While a strong immune response is essential to fight against viral infection, an immune system that continues to stay active long after the virus has been cleared can lead to lung damage.

Decreases in respiratory infections during the pandemic suggest there may be a continued role for the selective, non-mandated use of measures like masks and social distancing even post-COVID-19.
Infections diagnosed in a hospital between ages 11 and 19 are associated with an increased risk of multiple sclerosis.
Antibiotics do not shorten or reduce the severity of colds or flu, but they could produce adverse effects that make you feel even worse.
Resistant bacteria aren’t the only risk posed by overprescribing antibiotics. A more immediate risk is side-effects and reactions, which a new review shows are surprisingly frequent and often severe.
With all the attention focussed on combating the spread of COVID-19 it’s easy to forget the other health challenges that could affect us all.
Although it can sometimes be challenging, there are ways to distinguish respiratory symptoms caused by a virus and those caused by an allergy.

Scientists do not yet know the severity of the current coronavirus. A biologist who worked on the 2009 flu pandemic offers insights on that outbreak as well as the SARS outbreak.
Healthy, full-term Inuit babies are not eligible for palivizumab even though they have four to 10 times the rate of hospital admission compared to “high-risk” infants.
A drug called palivizumab can keep babies infected with respiratory syncytial virus (RSV) out of the hospital, but many Inuit babies, who have a higher risk of infection, are not getting it.
