The unknown disease, recorded in the South Indian city of Eluru in Andhra Pradesh, is not transmitted from person to person, District Collector Mutyala Raju Revu said.
Until now, the disease has not been transmitted from one person to another. There is no age limit either. People from areas where municipal water supply to Eluru is not available also fell ill, the local authorities' representative said.
According to him, the disease has struck even those people who drink only mineral water,
Hospitalized patients complained of foam at the mouth, tremors, sudden fainting, and dizziness. A total of 340 people were hospitalized, one died. However, 168 people were later discharged.
Doctors took blood tests and cerebrospinal fluid from the sick, made their computed tomography scan, and even tested them for coronavirus, but could not determine what happened. Authorities checked more than 57,000 homes, examined drinking water for heavy metals, but did not find any anomaly.
