India’s southern state of Kerala is currently facing an outbreak of the rare, but potentially serious Nipah virus with at least two deaths so far, according to local reports.

Health officials have closed schools and offices in Kerala and hundreds of residents are being tested.

Despite Nipah virus’s high fatality rate and no specific treatments available, experts said it’s very unlikely the virus will lead to a global emergency and that it’s a reminder of how habitat destruction has led to animals transmitting the disease to humans.
