Many human infections with other viral pathogens, such as influenza virus, do not produce a durable immune response....
In the medical management of patients affected by COVID-19, some valuable therapeutic strategies imply the use of AIDs, especially those non-steroidal AIDs (NSAIDs), to mitigate the ongoing excessive inflammatory response occurring after the early phases of the disease [22]. Indeed, several observ...
[92]. SARS-CoV-2 infection of neurons during the early phases results in anosmia, closely resembling the loss of smell observed after COVID-19 infection. Studies suggest a correlation between disease severity and the viral infective dose in K18-hACE2 mice, which may vary with different virus...
For example, if someone gets natural immunity from a COVID-19 infection, the immunity may fade after 3 months. On the other hand, a child who getsmeaslesis unlikely to ever catch it again. Here’s a look at the different types of immunity, including the differences between natural andvacc...
An unseasonably early crush of respiratory viral infections has once again raised the spectre of an “immunity debt,” a concept described by some as an unintended boomerang effect of distancing, masking and other COVID containment measures used to slow SARS-CoV-2’s spread. ...
