NEW DELHI (CNN) -- Health officials in India's Gujarat state are investigating a hepatitis outbreak that has left 19 people dead in less than two weeks, authorities said Wednesday.
Malayappan Thennarasan, the top administrative official of the state's Sabarkantha district, told CNN that another 70 patients have been hit with the same strain of virus in the past 10 days.
Of them, 17 are under hospitalization, he said.
It's being examined whether it is hepatitis B, according to Thennarasan. "It appears to be a mutant form (of hepatitis)," he said.
Among those dead are four women.
Thennarasan said it's not yet clear what caused the infection.
