At-home mask makers should carefully consider fit and fabric variables when designing face coverings to help prevent transmission of SARS-CoV-2.
Winter is flu season – could it be coronavirus season as well? The research is mixed, but other factors besides temperature and humidity have more to do with the spread of SARS-CoV-2.
Ever heard of 229E, OC43, NL63 and HKU1?
Two phrases you hear a lot these days are viral load and infectious dose. What do they mean? Do they reflect the severity of disease or whether someone will get severely ill? Two experts explain.
Some people’s immune systems aren’t able to stop foreign invaders, such as COVID-19, as well as the rest of the population. There are many reasons for this, including illness, medications and age.
Some of the false claims about coronavirus may be harmless. But others can be potentially dangerous.
Most people with coronavirus will recover but how long until you’re no longer infectious? Here’s what the science tells us so far.
When a new virus emerges and triggers a pandemic, it is important to trace its origins. Knowing more about how the virus jumped species in the first place can help curb future zoonotic diseases.
Africa is better prepared now to perform research in emerging infections than during the Ebola epidemics in West Africa.
University of Pittsburgh researchers are developing a vaccine patch for COVID-19 that is as easy to apply as a Band-Aid.
Australia is making good progress in flattening the curve, which will save our hospitals from being overwhelmed. But we still have to work out what comes next and how restrictions can be safely eased.
To boost your immune defenses against corona and other viruses, one of the most effective things you can do is maintain your natural circadian rhythms. Here’s how to do that.
For some diseases, the dose of virus a person is exposed to is directly linked to how severe the disease is.
Cooped up with a partner and nowhere to go to break it up? Coronavirus social distancing… or another day in retirement? Research on older couples holds tips for everyone else on how to deal.
The head lice drug Ivermectin has stopped SARS-CoV-2, the virus that causes COVID-19, from replicating in lab tests. But we don’t know if it will work as a treatment for people with coronavirus.
