Download our poster of the biggest milestones, from the discovery of the viral family in humans in the 1960s to the identification of SARS-CoV-2.

Milder, cold-causing members of this pathogenic viral family long remained under the radar, although they aren’t entirely harmless.

The host transcriptional signature elicited by the coronavirus appears to be less robust and lacks the induction of key antiviral genes.

The symptoms suggest SARS-CoV-2 might infect neurons, raising questions about whether there could be effects on the brain that play a role in patients’ deaths, but the data are preliminary.

Emerging data as well as knowledge from the SARS and MERS coronavirus outbreaks yield some clues as to why SARS-CoV-2 affects some people worse than others.

Under careful watch of the World Health Organization, doctors will test a range of COVID-19 therapies, including HIV and flu antivirals, blood plasma infusions, and traditional Chinese medicines.

The National Institute of Allergy and Infectious Diseases releases a series of images that offer a close up look at the novel coronavirus SARS-CoV-2.

The virus, which has sickened at least 59 people, does not appear to transmit easily between humans.

Health authorities have ruled out the usual suspects, leading to fears that a novel virus is causing the infections in Hubei Province.
