We recently heard reports of a new and dangerous 'hybrid' variant circulating in Vietnam. There is such as a thing as a hybrid viral variant — but this doesn't appear to be it.
The prevention of future pandemics requires examining viral family trees.

Bat hosts, lab leaks – tracing SARS-CoV-2 to its origins involves more than just tracking down patient zero.
We can help vaccines keep up with the mutating coronavirus by doubling down on preventive measures.
The UK government has claimed the new British variant of the coronavirus may be 30% more deadly.
Staff help a patient off the ambulance outside the hospital in Wuhan, China, January 2020.
The Conversation first reported on the novel coronavirus on January 13 2020. A virologist reflects on what happened since he first wrote that article.

It's the part of coronavirus that helps the virus get into your cells – and also the target of the leading vaccines.
There’s valuable data on the spread of COVID-19 in this wastewater.

As the world waits for vaccines against COVID-19, testing wastewater can give communities and smaller locales, such as school districts, valuable signals about infections trends.
People wearing masks walk in front of Pfizer’s headquarters in New York City. Pfizer and BioNtech are on track with a vaccine that is 90 per cent effective, say preliminary results, but they are not the only ones in the race.

Canada has set aside a total of 414 million doses of different types of vaccine. Some exploit known mechanisms, others are based on previously untested approaches.
Scientists handle virus samples every day but infections are incredibly rare – here's why.
An unprecedented level of research has gone into understanding the novel coronavirus. Here's what we still don't know.
The evidence suggests the novel coronavirus evolved naturally.
It's excellent this virus has been found early, but there is no evidence yet of human-to-human transmission.
A pandemic from a century ago doesn’t necessarily chart the course of the pandemic happening now.

Differences in the viruses' biology and societal contexts mean there's no guarantee today's pandemic will mirror the 'waves' of infection a century ago.
The US and its allies are demanding answers over how COVID-19 became a pandemic. But instead of pointing fingers at China, the inquiry should focus on scientific clues to help us thwart future disasters.
Rapid blood tests for coronavirus could fill a large gap in knowledge.

Expanding coronavirus testing is one of the most important tasks public health officials are tackling right now. But questions over accuracy of the two main types of tests have rightly caused concern.
While a few are killers, viruses are actually important to human health and incredibly useful in medicine.
