The discovery of Pteropine orthoreovirus raises the concern that dangerous bat viruses may be silently co-circulating with Nipah virus.
So far 5 hospital workers in Bengal state, India, have been infected with Nipah virus.
The study findings represent a "milestone" in efforts to prevent a deadly infection, experts say.
Those found in coastal South America, Southeast Asia, and equatorial Africa are more likely to carry pathogens such as SARS-CoV-2.
In September cholera cases were down 27% from August.
One child with an unknown exposure and 3 adults with a history of consuming raw palm sap, a known risk factor, died of unrelated infections.
The recent cases don't have epi connections, but fruit bats known to harbor the virus were seen in the outbreak area.
The man's illness was found during monitoring contacts of his father who recently died from a Nipah infection.
India has now reported 6 Nipah virus cases in the past year, all in the hot spot area in Kerala state.
So far, there are no known links between the 2 new cases.
