Zakażenie układu oddechowego
Objawy

Zakażenia układu oddechowego (RTI) obejmują spektrum od łagodnych infekcji górnych dróg oddechowych (URTI) do ciężkich zakażeń dolnych dróg oddechowych (LRTI), takich jak zapalenie płuc. Objawy URTI to m.in. ból gardła, katar, niewysoka gorączka i kaszel, natomiast LRTI charakteryzują się dusznością, gorączką, kaszlem z odkrztuszaniem zielonej lub żółto-brązowej plwociny oraz bólem w klatce piersiowej. Przebieg infekcji różni się w zależności od lokalizacji i wieku pacjenta – u dzieci mediana czasu trwania objawów wynosi około 9 dni, a u dorosłych 7-10 dni dla URTI i do 2-3 tygodni dla LRTI. Szczególnie niebezpieczne są zakażenia dolnych dróg oddechowych u niemowląt, osób starszych (>65 lat) oraz pacjentów z osłabionym układem odpornościowym lub chorobami przewlekłymi.

Objawy zakażenia układu oddechowego

Zakażenie układu oddechowego (RTI – Respiratory Tract Infection) to infekcja dotykająca części ciała zaangażowanych w oddychanie, takich jak zatoki, gardło, drogi oddechowe lub płuca. Spektrum kliniczne tych infekcji może być bardzo zróżnicowane – od łagodnych, samoograniczających się chorób, po ciężkie, zagrażające życiu stany wymagające hospitalizacji.12

Główne objawy zakażenia układu oddechowego

Typowe objawy zakażenia układu oddechowego obejmują:12

  • Kaszel (suchy lub produktywny, czasem z odkrztuszaniem plwociny)
  • Kichanie
  • Zatkany lub cieknący nos
  • Ból gardła
  • Bóle głowy
  • Bóle mięśniowe
  • Duszność
  • Uczucie ucisku w klatce piersiowej lub świszczący oddech
  • Wysoka temperatura (gorączka)
  • Ogólne złe samopoczucie

Objawy zakażeń górnych dróg oddechowych są zazwyczaj łagodniejsze i obejmują głównie dolegliwości ze strony nosa, gardła oraz zatok. Z kolei zakażenia dolnych dróg oddechowych często wiążą się z cięższym przebiegiem i mogą prowadzić do poważniejszych komplikacji.12

Różnice w objawach między zakażeniami górnych i dolnych dróg oddechowych

Symptomy zakażeń górnych dróg oddechowych (URTI – Upper Respiratory Tract Infection) obejmują:12

  • Ból gardła
  • Katar
  • Przekrwienie błony śluzowej nosa
  • Ból głowy
  • Niezbyt wysoka gorączka
  • Ucisk w okolicy twarzy
  • Kaszel

Natomiast objawy zakażeń dolnych dróg oddechowych (LRTI – Lower Respiratory Tract Infection) są zwykle poważniejsze i obejmują:12

  • Duszność
  • Osłabienie
  • Gorączka
  • Kaszel z odkrztuszaniem zielonej lub żółto-brązowej wydzieliny (plwociny)
  • Zmęczenie
  • Bóle mięśniowe
  • Ból lub dyskomfort w klatce piersiowej

Infekcje dolnych dróg oddechowych są zwykle dłuższe i cięższe niż infekcje górnych dróg oddechowych.12

Progresja i czas trwania objawów

Typowy przebieg czasowy zakażenia

Większość zakażeń układu oddechowego ustępuje w ciągu 1-2 tygodni.12 Jednak przebieg czasowy może się różnić w zależności od rodzaju zakażenia oraz ogólnego stanu zdrowia pacjenta:

  • Przeziębienie (common cold) – objawy zazwyczaj trwają 7-10 dni1
  • Kaszel może utrzymywać się do 3 tygodni, nawet po ustąpieniu innych objawów1
  • Grypa (influenza) – objawy mogą trwać do 2-3 tygodni, przy czym kaszel i zmęczenie mogą utrzymywać się nawet po ustąpieniu innych symptomów1

U dzieci obserwuje się dłuższy czas trwania objawów. Badania wskazują, że u 90% dzieci objawy ustępują po 23 dniach. Średni czas trwania objawów u dzieci wynosi 9 dni, przy czym u dzieci poniżej 3 roku życia mediana czasu trwania objawów wynosi 11 dni, a u starszych dzieci – 7 dni.12

Rozwój objawów w czasie

Przebieg zakażenia układu oddechowego zazwyczaj charakteryzuje się określoną sekwencją objawów:1

  1. Ból gardła jest często najwcześniejszym objawem
  2. Po 1-2 dniach dołącza się katar i kichanie
  3. Następnie pojawia się przekrwienie błony śluzowej nosa, zapalenie krtani i kaszel
  4. W początkowej fazie infekcji często występuje również złe samopoczucie, niewysoka gorączka, bóle mięśniowe i ból głowy

Objawy przeziębienia zazwyczaj nasilają się w ciągu pierwszych 2-3 dni, a następnie stopniowo ustępują.1 W przypadku infekcji bakteryjnych, jeśli nie są leczone, objawy mogą się utrzymywać lub nasilać.1

Objawy alarmowe wymagające interwencji medycznej

Chociaż większość zakażeń układu oddechowego ustępuje samoistnie, niektóre objawy powinny skłonić do kontaktu z lekarzem. Należy zasięgnąć porady medycznej, jeśli wystąpią następujące symptomy:12

  • Bardzo złe samopoczucie lub nasilające się objawy
  • Wysoka gorączka utrzymująca się ponad 3 dni
  • Odkrztuszanie krwi lub plwociny podbarwionej krwią
  • Kaszel utrzymujący się ponad 3 tygodnie
  • Ciąża
  • Wiek powyżej 65 lat
  • Osłabiony układ odpornościowy (np. z powodu chorób, takich jak cukrzyca, lub w wyniku chemioterapii)
  • Przewlekłe schorzenia, takie jak choroby serca, płuc lub nerek

Natychmiastowa pomoc medyczna jest zalecana, jeśli wystąpią następujące objawy:12

  • Utrzymująca się wysoka gorączka, która nie ustępuje
  • Szybki lub utrudniony oddech
  • Ból w klatce piersiowej
  • Objawy odwodnienia
  • Splątanie, dezorientacja lub senność
  • Sinawe zabarwienie skóry lub warg (sinica)

U dzieci dodatkowe objawy wymagające natychmiastowej konsultacji lekarskiej to:1

  • Zawroty głowy, omdlenia lub utrata przytomności
  • Gorączka powyżej 39,4°C
  • Świszczący oddech i/lub wysoki, piskliwy dźwięk podczas oddychania (stridor)
  • Wyraźne zapadanie się klatki piersiowej podczas oddychania lub kaszlu

Specyficzne objawy różnych typów zakażeń układu oddechowego

Przeziębienie

Przeziębienie (common cold) jest najczęstszym zakażeniem górnych dróg oddechowych. Jego objawy obejmują:12

  • Ból gardła
  • Katar
  • Kichanie
  • Kaszel
  • Ból głowy
  • Niewysoka gorączka
  • Zatkany nos

  • Chrypką lub utratą głosu
  • Bólem gardła
  • Suchym kaszlem
  • Koniecznością częstego odkrztuszania
  • Obrzękiem węzłów chłonnych

Zapalenie płuc

Zapalenie płuc (pneumonia) to poważna infekcja dolnych dróg oddechowych, której objawy obejmują:12

  • Ból w klatce piersiowej
  • Kaszel (często z odkrztuszaniem wydzieliny)
  • Gorączka
  • Zmęczenie
  • Trudności z oddychaniem
  • Utrata apetytu
  • Szybkie bicie serca
  • Potliwość i dreszcze
  • Sinawe zabarwienie skóry (w ciężkich przypadkach)

Zapalenie płuc może być poważną i potencjalnie śmiertelną infekcją, szczególnie u małych dzieci, osób starszych i pacjentów z istniejącymi wcześniej schorzeniami, u których istnieje zwiększone ryzyko powikłań, takich jak wysięk opłucnowy, ropień płuca lub sepsa.1

Zakażenia górnych/dolnych dróg oddechowych u dzieci

Zakażenia układu oddechowego są szczególnie częste u dzieci, zwłaszcza w wieku przedszkolnym i wczesnoszkolnym. Dzieci są bardziej podatne na te infekcje ze względu na relatywną niedojrzałość ich układu odpornościowego.12

Specyfika zakażeń układu oddechowego u dzieci

U dzieci zakażenia układu oddechowego mają pewne charakterystyczne cechy:12

  • Wyższa częstotliwość występowania – dzieci mogą doświadczać 5-10 przeziębień rocznie (w porównaniu do 2-4 u dorosłych)
  • Dłuższy czas trwania objawów – mediana 9 dni, ale u dzieci poniżej 3 roku życia może wynosić 11 dni
  • Większe ryzyko powikłań ze względu na węższe drogi oddechowe
  • Możliwość szybszej progresji choroby i rozwoju ciężkich objawów

Wąskie drogi oddechowe u małych dzieci mogą być znacznie zwężone przez stan zapalny i śluz, co utrudnia oddychanie. Niektóre dzieci z wirusowym zakażeniem dróg oddechowych mogą również rozwinąć zakażenie ucha środkowego (zapalenie ucha środkowego) lub tkanek płucnych (zapalenie płuc).1

Nawracające zakażenia dróg oddechowych u dzieci

Zakażenia układu oddechowego u dzieci mają tendencję do nawracania, co może prowadzić do znacznego obciążenia klinicznego i ekonomicznego dla pacjentów i ich rodzin. Nawracające infekcje mogą skutkować długoterminowymi powikłaniami, takimi jak:12

  • Infekcje wtórne
  • Świszczący oddech
  • Zwiększone ryzyko rozwoju astmy
  • Dysfunkcja układu odpornościowego wywołana przez wirusy

Nawracające infekcje dróg oddechowych u dzieci mogą prowadzić do błędnego koła nawracających RTI z nadkażeniami bakteryjnymi, zaostrzeniem kaszlu i zwiększonym ryzykiem rozwoju astmy.1

Czynniki ryzyka cięższego przebiegu i powikłań

Pewne grupy osób są bardziej narażone na cięższy przebieg zakażeń układu oddechowego i rozwój powikłań. Do głównych czynników ryzyka należą:12

Grupy zwiększonego ryzyka

  • Wiek – dzieci poniżej 5 lat (szczególnie niemowlęta) oraz osoby powyżej 65 roku życia
  • Osłabiony układ odpornościowy – osoby z chorobami takimi jak cukrzyca, poddawane chemioterapii, przyjmujące leki immunosupresyjne
  • Przewlekłe schorzenia – choroby serca, płuc (np. POChP, astma), nerek
  • Ciąża – kobiety w ciąży są bardziej podatne na powikłania zakażeń dróg oddechowych
  • Niedożywienie – stan odżywienia może wpływać na przebieg infekcji, szczególnie u dzieci

Potencjalne powikłania zakażeń układu oddechowego

Zakażenia układu oddechowego, szczególnie infekcje dolnych dróg oddechowych, mogą prowadzić do różnych powikłań:12

  • Zapalenie płuc – zakażenie tkanki płucnej prowadzące do zapalenia pęcherzyków płucnych
  • Zapalenie ucha środkowego – infekcja ucha środkowego, częsta u dzieci
  • Zapalenie opon mózgowych – w rzadkich przypadkach bakterie mogą dotrzeć do opon mózgowo-rdzeniowych
  • Gorączka reumatyczna – powikłanie zakażeń wywołanych przez paciorkowce grupy A
  • Szkarlatyna – powikłanie zakażeń paciorkowcowych
  • Sepsa – uogólniona, zagrażająca życiu reakcja organizmu na infekcję
  • Uszkodzenie narządów – w ciężkich przypadkach może dojść do uszkodzenia różnych narządów

Chociaż zakażenia górnych dróg oddechowych, takie jak przeziębienie, rzadko prowadzą do powikłań, zakażenia dolnych dróg oddechowych mogą powodować zapalenie w płucach, prowadząc do zapalenia płuc, które może być szczególnie niebezpieczne dla osób z grup podwyższonego ryzyka.1

Rozpoznanie i diagnostyka zakażeń układu oddechowego

Prawidłowe rozpoznanie zakażenia układu oddechowego jest kluczowe dla odpowiedniego postępowania i decyzji dotyczących leczenia.1

Diagnostyka kliniczna

Diagnoza zakażenia układu oddechowego jest zazwyczaj stawiana na podstawie objawów klinicznych i badania fizykalnego.1 Podstawowe elementy oceny obejmują:

  • Wywiad medyczny (czas trwania objawów, ich nasilenie, czynniki ryzyka)
  • Badanie fizykalne (ocena gardła, węzłów chłonnych, osłuchiwanie klatki piersiowej)
  • Pomiar parametrów życiowych (temperatura ciała, częstość oddechów, tętno)

W większości przypadków zewnętrzne objawy i symptomy są wystarczające do zdiagnozowania zakażenia układu oddechowego.1

Badania dodatkowe

W niektórych przypadkach, szczególnie przy podejrzeniu cięższych zakażeń dolnych dróg oddechowych lub powikłań, mogą być zalecane dodatkowe badania:12

  • Badania laboratoryjne – morfologia krwi, CRP (białko C-reaktywne), markery stanu zapalnego
  • Badania mikrobiologiczne – posiew plwociny, badanie wydzieliny z nosa/gardła
  • Badania obrazowertg klatki piersiowej (przy podejrzeniu zapalenia płuc)
  • Szybkie testy diagnostyczne – na obecność określonych patogenów (np. grypa, RSV, COVID-19)

Poziom podwyższenia CRP zwykle odpowiada nasileniu infekcji. Chociaż test ten nie może jednoznacznie określić rodzaju infekcji, zakażenia bakteryjne generalnie powodują większy wzrost CRP niż zakażenia wirusowe.1

W niektórych przypadkach konieczne może być badanie próbki wydzieliny w celu identyfikacji patogenu wywołującego zakażenie układu oddechowego.1

Przebieg i rokowanie

Większość zakażeń układu oddechowego ma stosunkowo dobry przebieg i rokowanie, szczególnie u zdrowych osób dorosłych.12

Typowy przebieg zakażenia

Przebieg zakażenia układu oddechowego zależy od lokalizacji infekcji i czynnika etiologicznego:12

  • Zakażenia górnych dróg oddechowych – zwykle trwają 7-10 dni, choć kaszel może utrzymywać się dłużej
  • Zakażenia dolnych dróg oddechowych – mogą trwać dłużej, nawet 2-3 tygodnie
  • W większości przypadków objawy osiągają szczyt w ciągu 2-3 dni, a następnie stopniowo ustępują

Według Amerykańskiego Towarzystwa Pulmonologicznego, zdrowa młoda osoba dorosła może wyzdrowieć z zakażenia dolnych dróg oddechowych, takiego jak zapalenie płuc, w ciągu około 1 tygodnia. U osób starszych pełny powrót do zdrowia może zająć kilka tygodni.1

Czynniki wpływające na rokowanie

Rokowanie w zakażeniach układu oddechowego zależy od kilku czynników:12

  • Rodzaj patogenu – infekcje wirusowe są zwykle łagodniejsze niż bakteryjne, choć istnieją wyjątki
  • Lokalizacja infekcji – zakażenia dolnych dróg oddechowych mają zazwyczaj cięższy przebieg
  • Wiek pacjenta – dzieci i osoby starsze są bardziej narażone na ciężki przebieg
  • Stan zdrowia – osoby z chorobami współistniejącymi mają wyższe ryzyko powikłań
  • Szybkość rozpoczęcia leczenia – wczesna interwencja może zmniejszyć ryzyko powikłań

Zapalenie płuc może być poważną i potencjalnie śmiertelną infekcją, szczególnie u małych dzieci, osób starszych i pacjentów z istniejącymi wcześniej schorzeniami, u których istnieje zwiększone ryzyko powikłań.1

Zakażenia dolnych dróg oddechowych są główną przyczyną zgonów wśród wszystkich chorób zakaźnych i stanowią znaczące obciążenie dla systemów opieki zdrowotnej na całym świecie.12

Rokowanie w poszczególnych grupach wiekowych

Rokowanie różni się znacząco w zależności od grupy wiekowej:12

  • Dzieci – zwykle dobra odpowiedź na leczenie, ale u niemowląt wyższe ryzyko powikłań
  • Dorośli – najczęściej dobry przebieg i pełne wyzdrowienie
  • Osoby starsze – wolniejszy powrót do zdrowia, wyższe ryzyko powikłań i śmiertelności

U osób starszych powrót do pełnej sprawności po zakażeniu dolnych dróg oddechowych może zająć nawet kilka tygodni.1

Mimo że większość zakażeń układu oddechowego ustępuje samoistnie, ważne jest monitorowanie przebiegu choroby, szczególnie u osób z grup podwyższonego ryzyka, aby w razie potrzeby wdrożyć odpowiednie leczenie.22

    https://www.nhs.uk/conditions/respiratory-tract-infection/
    Respiratory tract infections (RTIs) are infections of parts of the body involved in breathing, such as the sinuses, throat, airways or lungs. Most RTIs get better without treatment, but sometimes you may need to see a GP. […] Symptoms of a respiratory tract infection include: a cough you may bring up mucus (phlegm), sneezing, a stuffy or runny nose, a sore throat, headaches, muscle aches, breathlessness, tight chest or wheezing, a high temperature, feeling generally unwell. […] Most respiratory tract infections (RTIs) pass within 1 to 2 weeks. You can usually treat your symptoms at home. […] You have symptoms of a respiratory tract infection and: you feel very unwell or your symptoms get worse, you’ve had a high temperature for more than 3 days, you cough up blood or bloodstained mucus, you’ve had a cough for more than 3 weeks, you’re pregnant, you’re over 65, you have a weakened immune system for example, because you have a condition like diabetes or you’re having chemotherapy, you have a long-term health condition, such as a heart, lung or kidney condition.

    https://healthify.nz/health-a-z/r/respiratory-tract-infections
    Respiratory tract infections (RTIs) can affect both the upper and lower parts of your respiratory (breathing) system. […] They often occur after you get a cold or flu-like illnesses. […] Upper RTIs (eg, colds or sinus infections) can mostly be treated at home, but lower RTIs (eg, pneumonia) are more serious and generally need medical care. […] Lower RTIs, such as pneumonia, tend to be more serious than upper RTIs, such as colds or a sinus infection. […] Most upper RTIs can be treated at home, but young children, older adults, pregnant people or people with long-term health conditions who get a lower RTI may need to see a healthcare provider. […] Symptoms of upper URIs include: sore throat, runny nose, nasal congestion, headache, low-grade fever, facial pressure, cough. […] Symptoms of lower RTIs include: shortness of breath, weakness, fever, coughing with green or yellow/brown mucus (phlegm or sputum), fatigue, aching muscles, chest pain or discomfort.

    Symptoms will usually be at their worst after 23 days and will generally last for 58 days. However, some of the symptoms of flu (eg, cough and tiredness) can last for as long as 23 weeks. […] Laryngitis is an infection of your larynx, which results in a hoarse voice and difficulty speaking. […] Pneumonia is an inflammation of your lung tissue that is caused by an infection. The infection may be in one or both of your lungs and it can be caused by bacteria or a virus. […] A sore throat (throat infection, pharyngitis) is caused when a virus (or bacteria) infects the area at the back of your throat (pharynx). This causes redness and swelling (inflammation), and can be painful, especially when you swallow. […] Whooping cough (pertussis) can be a very serious respiratory tract infection that is very easily spread (highly contagious). Whooping cough usually starts off with cold-like symptoms, and develops into a cough.

    It takes 23 days for 90 percent of children to recover from respiratory tract infection symptoms. […] Overall, median duration of symptoms was 9 days. For children three years of age or younger, median symptom duration was 11 days compared to seven days for older children. Children whose parents reported lower respiratory tract symptoms (such as wet cough and wheeze) had median symptom duration of 12 days compared to eight days for those who had only upper respiratory tract symptoms (such as runny nose and sore throat). Among children with only upper respiratory tract symptoms, the most persistent symptom was runny nose, while the fastest symptom to resolve was earache. For children with at least one lower respiratory tract symptom, all symptoms persisted for three weeks; runny nose and wet cough were the most severe symptoms.
  • #1 Upper Respiratory Tract Infections With Focus on The Common Cold – StatPearls – NCBI Bookshelf
    https://www.ncbi.nlm.nih.gov/books/NBK532961/
    Upper respiratory tract infections (URTIs) are the most common infectious disease cause for patient evaluations worldwide. URTIs are typically self-limited and mild to moderate in severity. The most common manifestation of URTIs is the common cold. Due to overlapping symptoms of various viral and bacterial infections that can result in URTIs, making the diagnosis of the common cold is a challenge. The common cold is a syndrome that manifests as a mild-to-moderate, self-limited URTI, characterized by inflammation that causes malaise, nasal congestion, rhinorrhea, sneezing, pharyngitis, cough, and occasional fever and headache. Individual symptoms of the common cold can vary in severity and duration. In general, and accepting their subjective nature, symptoms tend to be mild to moderate in severity. Sore throat is often the earliest symptom, followed 1 to 2 days later by rhinorrhea and sneezing. Nasal congestion, laryngitis, and cough typically develop shortly thereafter. Malaise, low-grade fever, myalgias, and headache are common during the early phase of infection. Symptoms typically last 7 to 10 days, although cough can linger for several weeks. URTIs are the most common acute infectious diseases in the world. In the vast majority of cases, they tend to be self-limited but, on occasion, can evolve into chronic and significant complications. The vast majority of URTIs are self-limited and mild to moderate in severity. Common cold symptoms typically last from 7 to 10 days, although cough can linger for several weeks.

    https://www.medicalnewstoday.com/articles/323886
    Some common symptoms of pharyngitis include: a sore or scratchy throat, inflammation, fever, headache, difficulty swallowing. […] An individual needs medical attention if the following occurs: a high fever, severe respiratory distress, difficulty swallowing. […] URIs may resolve without treatment, or the symptoms may be mild and easy to treat at home. […] If any symptoms do not resolve with home care or if they get worse, a person should contact a doctor. […] According to the American Lung Association, certain bacteria and viruses responsible for URIs can lead to pneumonia. […] Typically, a URI lasts 710 days and, sometimes, up to three weeks. In some cases, these infections develop into more serious issues, such as sinus infections or pneumonia. […] Most people recover from a URI within two weeks with or without OTC or home treatments. However, if the symptoms get worse or are severe, a person should contact a doctor.

    Whether you know it or not, chances are youve had a respiratory tract infection (RTI) or upper respiratory tract infection (URI) at some point in your life. […] A bacterial respiratory tract infection is an infection of the sinuses, throat, airway, or lungs. Bacterial infections may develop after having a viral illness like a cold or the flu. Symptoms tend to localize to one particular area. […] A few warning signs that your cold has progressed from a viral infection to a bacterial infection are: Symptoms lasting longer than 10-14 days […] A fever higher than 100.4 degrees […] A fever that gets worse a couple of days into the illness, rather than getting better […] White pus-filled spots on the tonsils.

    RTIs are quite common and create hassles for the child, parents, siblings, teachers and school-staff. Frequent bouts of RTI lead to missed days from school or play, and reduced performance. This in turn can affect their emotional health. Parents should be vigilant about signs and symptoms of RTIs, so that timely treatment can be provided. […] Symptoms of RTIs caused by viruses include runny nose, cough, fever, sore throat, hoarse voice, fatigue, weakness, lack of energy, red eyes/pink eyes with yellowish discharge from the eyes, and swelling on the sides of the neck (due to swollen lymph nodes). […] When to see a doctor includes dizziness, fainting or loss of consciousness (called syncope), fever that’s higher than 103 F, rapid or heavy breathing and difficulty in breathing, frequent and severe cough accompanied by vomiting, wheezing and/or a high-pitched whistling sound while breathing out, retractions (a deep outline of the ribcage is visible) while breathing or coughing, and stridor, which is a harsh and raspy vibration while breathing out (similar to sounds made by a seal).

    https://brieflands.com/articles/apid-20283.html
    Respiratory tract infections (RTIs) affect children all over the world and are associated with significant morbidity and mortality. RTIs are usually triggered by viruses, though bacterial infections are also common. […] Children are particularly susceptible to RTIs due to the relative immaturity of their immune systems, and genetic factors (such as family history of atopy) and/or environmental factors (such as exposure to pollution and pathogens) also render certain populations more vulnerable to infection. Furthermore, RTIs tend to be recurrent and can result in multiple infections per year. […] The main pathogens that trigger respiratory infections are viruses (such as the respiratory syncytial viruses, rhinoviruses, and influenza viruses). Although viruses are often responsible for RTIs, bacterial super-infections commonly occur. Bacterial infections are observed in up to 60% of patients whose RTI symptoms last for 10 days or more.

    https://www.kauveryhospital.com/blog/pulmonology/respiratory-tract-infections-in-children-and-treatment-methods/
    Respiratory Tract Infections are a common condition with children in the age-group of 3 to 12 years. The Immune system of children are weaker compared to that of adults, so it’s easy to develop infections. While most infections are not very serious and can be easily managed, in some cases, they lead to complications or become fatal even. That is why, it’s important for parents and educators to be aware of them, so that timely action can be taken in the likelihood of infection. […] Children in the age-group of 2 to 12 are highly prone to RTIs. There are several reasons for this. To begin with, their immune systems are not as sturdy as that of adults. Secondly, they meet each other often at school and at play. Some of these infections spread through droplets in the air, so its easy to catch them. Further, when children come in contact with other infected children, and then touch their eyes, nose or mouth, the pathogens are easily ingested/inhaled into the body. Finally, children do not follow hand-washing routines as rigorously as adults do.

    Respiratory tract infection (RTI) refers to a range of infections that can occur in the upper and lower respiratory tract. Upper respiratory tract infections tend to be less severe than lower; for example tonsillitis, laryngitis and the common cold are URTIs, while bronchitis and pneumonia are LRTIs. […] RTI illnesses share many symptoms and signs, most notably sneezing, sore throat, cough, nasal congestion and discharge, and some malaise, muscle fatigue and pain. Symptoms of itchy, watery eyes, fever and headache may point toward an allergy or influenza rather than a URTI. […] The seriousness of LRTIs necessitates rapid and accurate diagnosis of the infection in order to minimise its effects. […] Diagnosis of an RTI can be achieved through a physical examination, as outward signs and symptoms will generally be enough to indicate the presence of an infection. […] A mild URTI will not require any medical intervention, while a serious LRTI will often lead to hospitalisation.

    Upper respiratory infection in cats are extremely common. Fortunately, however, severe illnesses that are secondary to URTIs are much less common and the vast majority of cats make a rapid and full recovery. Therefore, the prognosis is very good in most cats. Left untreated, feline upper respiratory infections can occasionally progress to pneumonia or have other serious complications, such as chronic breathing difficulties.

    https://www.ncbi.nlm.nih.gov/books/NBK532961/
    Upper respiratory tract infections (URTIs) are the most common infectious disease cause for patient evaluations worldwide. URTIs are typically self-limited and mild to moderate in severity. The most common manifestation of URTIs is the common cold. Due to overlapping symptoms of various viral and bacterial infections that can result in URTIs, making the diagnosis of the common cold is a challenge. The common cold is a syndrome that manifests as a mild-to-moderate, self-limited URTI, characterized by inflammation that causes malaise, nasal congestion, rhinorrhea, sneezing, pharyngitis, cough, and occasional fever and headache. Individual symptoms of the common cold can vary in severity and duration. In general, and accepting their subjective nature, symptoms tend to be mild to moderate in severity. Sore throat is often the earliest symptom, followed 1 to 2 days later by rhinorrhea and sneezing. Nasal congestion, laryngitis, and cough typically develop shortly thereafter. Malaise, low-grade fever, myalgias, and headache are common during the early phase of infection. Symptoms typically last 7 to 10 days, although cough can linger for several weeks. URTIs are the most common acute infectious diseases in the world. In the vast majority of cases, they tend to be self-limited but, on occasion, can evolve into chronic and significant complications. The vast majority of URTIs are self-limited and mild to moderate in severity. Common cold symptoms typically last from 7 to 10 days, although cough can linger for several weeks.

    In another pilot study to investigate CRP POCT in a community pharmacy patients accessed the scheme by either referral from GPs, pharmacy staff or self-referral. This study showed high degrees of patient satisfaction with concurrent reduction in unnecessary antibiotic prescribing by 86%. […] The accurate and rapid assessment of whether patients need antibiotics when they present to primary care with symptoms of RTI continues to challenge primary care clinicians and researchers. […] There is overwhelming evidence that CRP POCT can offer a significant strengthening of primary care clinicians diagnostic precision in addressing whether or not a patient presenting with symptoms of RTI needs antibiotics or not.

    Some common symptoms of pharyngitis include: a sore or scratchy throat, inflammation, fever, headache, difficulty swallowing. […] An individual needs medical attention if the following occurs: a high fever, severe respiratory distress, difficulty swallowing. […] URIs may resolve without treatment, or the symptoms may be mild and easy to treat at home. […] If any symptoms do not resolve with home care or if they get worse, a person should contact a doctor. […] According to the American Lung Association, certain bacteria and viruses responsible for URIs can lead to pneumonia. […] Typically, a URI lasts 710 days and, sometimes, up to three weeks. In some cases, these infections develop into more serious issues, such as sinus infections or pneumonia. […] Most people recover from a URI within two weeks with or without OTC or home treatments. However, if the symptoms get worse or are severe, a person should contact a doctor.

    Respiratory tract infections (RTIs) are among the most common reasons why patients visit their physicians. These infections can range from mild, self-limiting, or life-threatening requiring hospitalization. […] RTIs can be classified as upper and lower respiratory tract infections depending on the site of the infection in the respiratory system. However, in many cases, viruses may enter the upper respiratory tract and subsequently reach the lower respiratory tract. […] Upper respiratory tract infections (URIs) affect the respiratory tract above the lungs including the nose, throat, nasopharynx, sinus, larynx, epiglottis, or trachea causing rhinitis, pharyngitis, nasopharyngitis, sinusitis, laryngitis, epiglottitis or tracheitis respectively. […] URIs are caused by viruses in approximately 90 to 98 percent of cases.

    Respiratory tract infections (RTIs) can affect both the upper and lower parts of your respiratory (breathing) system. […] They often occur after you get a cold or flu-like illnesses. […] Upper RTIs (eg, colds or sinus infections) can mostly be treated at home, but lower RTIs (eg, pneumonia) are more serious and generally need medical care. […] Lower RTIs, such as pneumonia, tend to be more serious than upper RTIs, such as colds or a sinus infection. […] Most upper RTIs can be treated at home, but young children, older adults, pregnant people or people with long-term health conditions who get a lower RTI may need to see a healthcare provider. […] Symptoms of upper URIs include: sore throat, runny nose, nasal congestion, headache, low-grade fever, facial pressure, cough. […] Symptoms of lower RTIs include: shortness of breath, weakness, fever, coughing with green or yellow/brown mucus (phlegm or sputum), fatigue, aching muscles, chest pain or discomfort.
