RSV infection shows distinctly different symptoms, depending on the age of the infected person. In children under two, the virus causes a serious lower respiratory infection in the lungs. In older children and healthy adults, it causes a mild upper respiratory infection often mistaken for thecommon...
commonly bacterial or viral. In the viral type, a pathogen replicates inside a cell and causes a disease, such as the flu. Chronic diseases, such as asthma, are persistent and long-lasting. They can relapse and the patient can go into remission, only to suffer symptoms again at a later ...
filamentous hemagglutinin. The bacteria then grow at the site of infection and cause disease symptoms through the production of exotoxins. One of the main virulence factors of this organism is anA-B exotoxincalled thepertussis toxin (PT). When PT enters the host cells, it increases the cyclic...
During their first RSV infection, 25–40% of infected infants and young children have signs or symptoms of bronchiolitis or pneumonia and 0.5–2% require hospitalization. In contrast, hospitalization will be required in up to 25% of high-risk children such as those with a history of prematurity...

In total, 357 students living in 86 dormitory rooms in Shanxi University were randomly selected to survey symptoms of infections. Settled air dust was collected to characterize bacterial compositions by 16S rRNA sequencing. The overall microbial richness was not associated with respiratory infections, ...

Additionally, a significantly higher bacterial burden was found in the lungs of 1,25(OH)2D3-treated mice compared to the control group, hence implying the potential benefit of vitamin D supplementation in a better clearance of Mtb infection [89]....
Nausea,vomiting, anddiarrheaare not usually associated with an acute upper respiratory infection; however, further evaluation by a healthcare practitioner may be necessary if these symptoms occur. Although infants often catch colds, babiesless than 3 months of age who develop fever should be seen im...
