  https://www.mayoclinic.org/diseases-conditions/respiratory-syncytial-virus/symptoms-causes/syc-20353098

  Respiratory syncytial virus (RSV) causes infections of the lungs and respiratory tract. It’s so common that most children have been infected with the virus by age 2. Respiratory syncytial (sin-SISH-ul) virus can also infect adults. […] In adults and older, healthy children, respiratory syncytial virus (RSV) symptoms are mild and typically mimic the common cold. Self-care measures are usually all that’s needed to relieve any discomfort. […] RSV can cause severe infection in some people, including babies 12 months and younger (infants), especially premature infants, older adults, people with heart and lung disease, or anyone with a weak immune system (immunocompromised). […] Signs and symptoms of respiratory syncytial virus infection most commonly appear about four to six days after exposure to the virus. In adults and older children, RSV usually causes mild cold-like signs and symptoms. These may include: Congested or runny nose, Dry cough, Low-grade fever, Sore throat, Sneezing, Headache.

  RSV is a viral illness that causes symptoms such as trouble breathing. Its the most common cause of inflammation of the small airways in the lungs (bronchiolitis) and pneumonia in babies. […] Symptoms start about 2 to 5 days after contact with the virus. […] The early phase of RSV in babies and young children is often mild, like a cold. In children younger than age 3, the illness may move into the lungs and cause coughing and wheezing. In some children, the infection turns to a severe respiratory disease. Your child may need to be treated in the hospital to help with breathing. […] The most common symptoms of RSV include: Runny nose, Fever, Cough, Short periods without breathing (apnea), Trouble eating, drinking, or swallowing, Wheezing, Flaring of the nostrils or straining of the chest or stomach while breathing, Breathing faster than normal, or trouble breathing, Turning blue around the lips and fingertips.

• #1 RSV Timeline of Symptoms and Contagion

  https://www.webmd.com/lung/rsv-timeline

  Respiratory syncytial virus (RSV) is a common respiratory virus. Most people have it before age 2, but older kids and adults also get it. […] RSV symptoms in adults usually go away in about a week or two. The virus is usually contagious for 3 to 8 days, often even before you know you have it. […] Most of the time when you have RSV, you’ll be contagious for 3 to 8 days. You could spread it before you know you’re sick. But babies and people with weak immune systems can carry RSV for a lot longer. It also can cause severe illness in some cases. […] RSV symptoms in adults usually go away in about a week or two at most. It’s possible you could be sick longer if you end up with pneumonia or some other complication. […] RSV can be worse and sometimes even dangerous for babies and very young children. But most kids get it early, and it usually looks like a cold and gets better. Some kids can get sick for longer and can spend time in the hospital. It’s also possible for infants to spread RSV for up to 4 weeks, even after they don’t seem sick anymore.

  Respiratory syncytial virus (RSV) is an RNA virus that belongs to the Pneumoviridae family along with the human metapneumovirus and consists in two genotypes (A and B). RSV causes a wide spectrum of respiratory disease, from mild upper respiratory tract infections (in most cases) to life threatening lower respiratory tract infections. Infants, especially those under six months of age, are at highest risk of severe RSV disease and death. […] Signs and symptoms of upper respiratory illness include: runny nose, sore throat, headache, fatigue, fever. It is to be noted that although most children may present with fever during RSV infection, a certain proportion of young children may not. Signs and symptoms consistent with lower respiratory tract infection include: cough, shortness of breath, fast breathing, bronchospasm, wheezing. Severe lung disease can result in low oxygen levels in the body, respiratory muscle fatigue and can sometimes result in death. RSV-LRTI in early life may lead to long-term respiratory consequences, including repeat hospitalizations for respiratory illness during infancy, recurrent wheeze and/or asthma, and impaired lung health beyond infancy. […] RSV infection in elderly adults can exacerbate chronic underlying illnesses, such as lung and heart disease.

Most people recover in a week or two, but RSV can be serious, especially for infants, young children, older adults and people with a compromised immune system. […] RSV causes coughs and colds every winter and is the most common cause of bronchiolitis (inflammation of the small airways in the lung) and pneumonia (lung infection) in infants under 1 year of age. […] Symptoms can appear between 2 to 8 days after a person is infected and include the following: Fever, Runny nose, Sneezing, Cough and sometimes croup (a barking cough caused by inflammation of the upper airways), Wheezing, Decreased appetite, Ear infections (in children). […] In very young infants, irritability, decreased activity and breathing difficulties may be the only symptoms of infection. Lower respiratory tract infection, such as bronchiolitis, pneumonia or pneumonitis, are most likely to occur during a child’s first infection with RSV. […] Immunity is incomplete and short-lived with RSV. Repeated respiratory infections can occur, though these are usually mild and become less common with increasing age.

• #1 Respiratory Syncytial Virus Infection Clinical Presentation: History and Physical Examination

  https://emedicine.medscape.com/article/971488-clinical

  Patients with respiratory syncytial virus (RSV) infection may present with the following symptoms: Fever (typically low-grade) […] Cough […] Tachypnea […] Cyanosis […] Retractions […] Wheezing […] Rales […] Sepsislike presentation or apneic episodes (in very young infants). Physical examination of the infant with RSV lower respiratory tract infection (LRTI) reveals evidence of diffuse small airway disease. On inspection, the characteristic examination findings are the presence of rhinorrhea, tachypnea, intercostal and subcostal retractions. Nasal flaring and tracheal tugging may be present in severe cases of bronchiolitis. On auscultation, the presence of coarse or fine crackles (rales) are typical, sometimes associated with prolonged expiratory phase. The course of bronchiolitis varies and may require serial observations to adequately assess illness acuity. The decision to hospitalize an infant with RSV infection can be challenging. Among the more consistent and reliable findings in severe RSV disease are decreased oxygen saturations; thereby hypoxia (oxygen saturation 90 %) in an infant should be considered an indication for further inpatient monitoring. Rapid fluctuations in clinical manifestations are characteristic of RSV, thereby serial assessments either in the office or the hospital settings are helpful.

  The majority of children hospitalized for an RSV infection are under the age of six months. The elderly (those 65 years of age and older), premature infants, persons with chronic lung or heart problems, or persons with weak immune systems are at higher risk for developing serious illness. […] The diagnosis is usually made by the pattern of a child’s symptoms (a clinical diagnosis), especially if he or she has a cold and is wheezing. RSV can be confirmed by checking for the virus in nasopharyngeal specimens or by growing the virus from nasal swabs, nasal washes, or tracheal secretions. […] There is currently no vaccine to prevent RSV infection. Researchers are working to develop RSV vaccines. Because RSV infection is often resolved on its own, treatment of mild symptoms is not necessary for most people. For babies and children who are at high risk of developing severe RSV, preventive medication is available. Parents of an infant who is premature, has a chronic lung or heart condition, or has a weak immune system should contact their doctor or healthcare provider.

  https://www.ncbi.nlm.nih.gov/books/NBK459215/

  The human respiratory syncytial virus (RSV) is one of the most common viruses to infect children worldwide and increasingly is recognized as an important pathogen in adults, especially the elderly. The most common clinical scenario encountered in RSV infection is an upper respiratory infection, but RSV commonly presents in young children as bronchiolitis, a lower respiratory tract illness with small airway obstruction, and can rarely progress to pneumonia, respiratory failure, apnea, and death. […] The mainstay of treatment for the vast majority of RSV infections is supportive, but passive preventive immunization is available for at-risk children, including premature infants and infants with a history of cardiac, pulmonary, or neuromuscular diseases. […] RSV typically manifests as an upper respiratory illness, with the possibility of lower respiratory tract involvement, and historical and examination findings differ based on the location and severity of the disease. If limited to the upper respiratory tract, RSV presents with rhinorrhea, nasal congestion, cough, sneezing, and sometimes fever and myalgia. In some patients, especially those with risk factors for severe disease who are under the age of 2 years, RSV will progress to lower respiratory tract involvement with various permutations of the classic findings of bronchiolitis: rhonchorous breath sounds, tachypnea, accessory muscle use, wheezes, and prolonged expiration. In severe cases, it may also present with findings of viral pneumonia, hypoxia, lethargy, apnea, and acute respiratory failure.

  Respiratory syncytial virus (RSV) is an RNA virus that belongs to the Pneumoviridae family along with the human metapneumovirus and consists in two genotypes (A and B). RSV causes a wide spectrum of respiratory disease, from mild upper respiratory tract infections (in most cases) to life threatening lower respiratory tract infections. Infants, especially those under six months of age, are at highest risk of severe RSV disease and death. […] Signs and symptoms of upper respiratory illness include: runny nose, sore throat, headache, fatigue, fever. It is to be noted that although most children may present with fever during RSV infection, a certain proportion of young children may not. Signs and symptoms consistent with lower respiratory tract infection include: cough, shortness of breath, fast breathing, bronchospasm, wheezing. Severe lung disease can result in low oxygen levels in the body, respiratory muscle fatigue and can sometimes result in death. RSV-LRTI in early life may lead to long-term respiratory consequences, including repeat hospitalizations for respiratory illness during infancy, recurrent wheeze and/or asthma, and impaired lung health beyond infancy. […] RSV infection in elderly adults can exacerbate chronic underlying illnesses, such as lung and heart disease.

Physical examination of the infant with RSV lower respiratory tract infection (LRTI) reveals evidence of diffuse small airway disease. On inspection, the characteristic examination findings are the presence of rhinorrhea, tachypnea, intercostal and subcostal retractions. Nasal flaring and tracheal tugging may be present in severe cases of bronchiolitis. On auscultation, the presence of coarse or fine crackles (rales) are typical, sometimes associated with prolonged expiratory phase. The course of bronchiolitis varies and may require serial observations to adequately assess illness acuity. The decision to hospitalize an infant with RSV infection can be challenging. Among the more consistent and reliable findings in severe RSV disease are decreased oxygen saturations; thereby hypoxia (oxygen saturation 90 %) in an infant should be considered an indication for further inpatient monitoring. Rapid fluctuations in clinical manifestations are characteristic of RSV, thereby serial assessments either in the office or the hospital settings are helpful.
