Scientists have discovered a new coronavirus in a species of bat in Myanmar as part of routine surveillance for the PREDICT project. A second virus was also detected in Myanmar for the first time; it had been previously detected in bats in Thailand.
A newly identified coronavirus, swine acute diarrhea syndrome coronavirus (SADS-CoV), 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.
To date, there has been no effective antiviral drug for any known coronavirus.
Researchers identified from suckling piglets with diarrhea in China a new bat-HKU2–like porcine coronavirus (porcine enteric alphacoronavirus).
The finding could help researchers better predict where these viruses are likely to jump from animals to humans.
Experiments with the virus (PREDICT/PDF-2180) show that while its genetics are similar to MERS-coronavirus there are significant differences in its spike gene.
