Our first exposure to a pathogen, either naturally or via vaccination, can affect how our immune system responds in the future to the same or similar pathogens.
Some insights into previous outbreaks of human coronaviruses may be useful in explaining the comparatively ‘low’ numbers of COVID-19 infections and mortality in people with HIV in South Africa.
During the last six months, news reports have mentioned dozens of drugs that may be effective against the new coronavirus. Here we lay out the evidence and reveal which ones are proven to work. Or not.
Zoologists have known for decades that some of the most devastating viral infections originate from animals. Their data and research can be used in efforts to prevent pandemics.
Bats have been the reservoir for recent disease outbreaks, including SARS and the current COVID-19 pandemic. But it’s human activity that allows the virus to cross over.
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.
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.
The new coronavirus, SARS-CoV-2, spreads faster than the H1N1 influenza virus and is much deadlier. SARS-CoV-2 is particularly skilled at keeping cells from calling out for help.
In the most severe cases, COVID-19 patients need oxygen pumped directly into their airways, or even be hooked up to a machine that does the job of their heart and lungs.
A medicinal chemist addresses questions about chloroquine and hydroxychloroquine: what it is, whether it is effective against COVID-19 and whether it can treat and/or prevent this disease.
A new coronavirus related to SARS and MERS has now traveled from China to the United States. A genetic analysis reveals that this deadly pathogen may have originated in snakes.
