As of September 27, India reported six lab-confirmed Nipah infections, including two fatalities, from Kozhikode, Kerala. All cases were males aged 9 to 45.
“The first death occurred on August 30, 2023, and the second death on September 11, 2023,” WHO noted. “The source for the first case is unknown, but subsequent cases are contacts of the first case.”
