A mystery illness has reportedly left 227 people hospitalised and at least one dead in a town in India.

The patients in Eluru in the southern state of Andhra Pradesh are said to have suffered fits, burning eyes, vomiting and some have even been falling unconscious with the illness.

It comes as the country still has the second-highest coronavirus caseload in the world with over 9 million cases.

The state’s health minister, Alla Kali Krishna Srinivas, said that the patients who have the mystery illness had all tested negative for coronavirus.  

Blood samples were taken from patients and no evidence of any viral infection was revealed, according to Mr Srinivas.    

He said: ‘We ruled out water contamination or air pollution as the cause after officials visited the areas where people fell sick.

‘It is some mystery illness and only lab analysis will reveal what it is.’

Seventy people have been discharged, while another 157 are still being treated in hospitals.

One doctor in Eluru told The Indian Express: ‘The people who fell sick, especially the children, suddenly started vomiting after complaining of burning eyes. Some of them fainted or suffered bouts of seizures’.  

Jaganmohan Reddy, the state’s chief minister said that special medical teams are being sent to Eluru to investigate the cause of the illness. He also said he visited a hospital in the town to meet the patients and their families.
