In early 2020 we didn’t know whether a COVID vaccine was possible. And we changed our minds on face masks and surface transmission.
Some viruses go extinct, while others stick around. The virus that causes COVID-19 seems likely to remain with us for the long term.
The research community is taking a closer look at the lab-leak hypothesis for the origin of COVID-19, prompting discussion about the risks and benefits of engineering viruses.
A bat virus discovered a decade ago in Cambodia indicates that pangolin trafficking remains a credible explanation for the origin of the Covid-19 pandemic.
The SARS-CoV-2 virus at the origin of the Covid-19 pandemic is one ten-thousandth of a millimeter in diameter. How can such a microscopic organism have such an immense impact on global health?
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.
Many people are reporting persistent symptoms like headaches and shortness of breath after two months or more since being infected.
Kinases are cellular control switches. When they malfunction, they can cause cancer. The coronavirus hijacks these kinases to replicate, and cancer drugs that target them could fight COVID-19.
Is it possible that people who recover from COVID-19 will be plagued with long term side effects from the infection? An infectious disease physician reviews the evidence so far.
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.
The use of antihypertension medication during the coronavirus pandemic has been a subject of hot debate but people should be cautious about simple conclusions.
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.
COVID-19 and SARS are both deadly – but different. SARS symptoms were quick to appear, making it easier to contain. Because health officials were able to contain it, the virus died off.
The danger of treating COVID-19 as an astronomically rare and improbable event is that we will treat it as such and fail to prepare for the next pandemic. And there will be another pandemic.
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.
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.
Could the 1889-1890 pandemic have been the result of cow coronaviruses jumping to humans?
Scientists need to close the knowledge gap around COVID-19 and the virus that causes it.
