A newly identified coronavirus that killed nearly 25,000 piglets in 2016-17 in China emerged from horseshoe bats near the origin of the severe acute respiratory syndrome coronavirus (SARS-CoV), which emerged in 2002 in the same bat species. The new virus is named swine acute diarrhea syndrome coronavirus (SADS-CoV). It does not appear to infect people, unlike SARS-CoV which infected more than 8,000 people and killed 774. No SARS-CoV cases have been identified since 2004. The study investigators identified SADS-CoV on four pig farms in China’s Guangdong Province.
MERS and SARS News Releases
An experimental treatment developed from cattle plasma for Middle East respiratory syndrome (MERS) coronavirus infection shows broad potential, according to a small clinical trial led by National Institutes of Health scientists and their colleagues. The treatment, SAB-301, was safe and well tolerated by healthy volunteers, with only minor reactions documented.
National Institutes of Health scientists and colleagues report that an experimental vaccine given six weeks before exposure to Middle East respiratory syndrome coronavirus (MERS-CoV) fully protects rhesus macaques from disease.
A two-step regimen of experimental vaccines against Middle East respiratory syndrome (MERS) prompted immune responses in mice and rhesus macaques, report National Institutes of Health scientists who designed the vaccines.
