The number of cases spikes as the World Health Organization plans an emergency meeting on containing the epidemic.

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.

The virus caused an outbreak that began in Guangdong Province and left nearly 25,000 piglets dead. 

Understanding the patterns of diversity in bat-hosted viruses may help researchers better predict when and where outbreaks may occur.

The creation of a chimeric SARS-like virus has scientists discussing the risks of gain-of-function research.

In the wake of a handful of biosafety lapses at federal research facilities, the US government is temporarily halting funding for new studies aiming to give novel functions to influenza, SARS, and MERS viruses.

Whole-genome sequences for two novel coronaviruses from Chinese horseshoe bats are the most closely related to the severe acute respiratory syndrome coronavirus to date.

As researchers test a treatment for Middle East respiratory syndrome, the deadly coronavirus that causes it slowly reveals itself.
