Unidentified illness hospitalizes more than 300 people in India

An unidentified illness has hospitalized more than 300 people in southeastern India, including one who has died, according to local officials investigating the cases, the CNN reported.

Patients in the city of Eluru, in the state of Andhra Pradesh, reported a range of symptoms including seizures, loss of consciousness and some nausea over the weekend, said Dolla Joshi Roy, the district surveillance officer of Eluru's West Godavari District.

This comes as India continues to battle the Covid-19 pandemic, with the world's second-highest number of infections. Andhra Pradesh is one of the worst-affected states, and currently has more than 800,000 confirmed cases.

But Covid-19 wasn't the cause of the mass hospitalizations over the weekend.

"All patients have tested negative for Covid-19," said Roy, adding that about 180 patients have now been discharged, while the rest are "stable." The patient who died had reported similar symptoms to the others, but then had a fatal but unrelated cardiac arrest, she said.

A note released by Andhra Pradesh's Health Department said that initial blood tests did not find any evidence of a viral infection, such as dengue or chikungunya, which are both caused by mosquito bites.

Authorities are now testing water samples in Eluru for contamination, after all the patients were found to receive their water from a common source. Samples have been collected from 57,863 households and sent to a forensic laboratory.

"The cause is still unknown but still we are doing all kinds of testing, including testing food and milk," said Roy.
Specialists from the All India Institute of Medical Sciences and a neurologist from out of state have also arrived in Eluru to conduct further neurotoxic tests, and are waiting for the results.

The Chief Minister of Andhra Pradesh, Y.S. Jaganmohan Reddy, visited the patients on Monday.
