Following initial infection via the eyes or nose, the virus infects the epithelial cells of the upper and lower airway, causing inflammation, cell damage, and airway obstruction. [2] A variety of methods are available for viral detection and diagnosis of RSV including antigen testing, molecular testing, and viral culture. [3]
Acute bronchiolitis is usually the result of viral infection by respiratory syncytial virus (RSV) (59.2% of cases) or human rhinovirus (19.3% of cases). [7] Diagnosis is generally based on symptoms. [1] Tests such as a chest X-ray or viral testing are not routinely needed, but may be used to rule out other diseases. [2]
Croup (/ k r uː p / KROOP), also known as croupy cough, is a type of respiratory infection that is usually caused by a virus. [2] The infection leads to swelling inside the trachea, which interferes with normal breathing and produces the classic symptoms of "barking/brassy" cough, inspiratory stridor and a hoarse voice. [2]
One of the most common causes is Staphylococcus aureus and often follows a recent viral upper respiratory infection. Bacterial tracheitis is a rare complication of influenza infection. [ 4 ] It is the most serious in young children, possibly because of the relatively small size of the trachea that gets easily blocked by swelling.
(a) hMPV model structure indicating viral proteins encoded by (b) the viral genome. The genomic organisation of HMPV is similar to RSV ; however, HMPV lacks the non-structural genes , NS1 and NS2, and the HMPV antisense RNA genome contains eight open reading frames in slightly different gene order than RSV (viz. 3’-N-P-M-F-M2-SH-G-L-5’).

Fact check: FDA still recommends COVID-19 vaccine, contrary to viral claim He added that the study results are not applicable to adults because the study only included children and adolescents.
Viral pneumonia is a pneumonia caused by a virus. Pneumonia is an infection that causes inflammation in one or both lungs. Pneumonia is an infection that causes inflammation in one or both lungs. The pulmonary alveoli fill with fluid or pus making it difficult to breathe. [ 1 ]
This medicine does not effectively treat a viral infection like sore throats, influenza, bronchitis, sinusitis and common respiratory tract infections. [15] [16] This is because antibiotics were developed to target features of bacteria that are not present in viruses, and so antibiotics are ineffective as antiviral agents. [17] [18]
