New Delhi (PTI): The prolonged heatwave sweeping large parts of the country has claimed more lives, with 143 recorded deaths and 41,789 people suffering from suspected heatstroke between March 1 and June 20 this year, Health ministry sources said on Friday.

However, the heatwave toll is expected to be higher than this as the data compiled under the National Heat-Related Illness and Death Surveillance by the National Centre for Disease Control (NCDC) does not have updated submissions from states.

Several health facilities are also yet to upload data on number of heatwave casualties.

According to the official data, on June 20 itself there have been 14 confirmed deaths due to heatstroke and nine deaths due to suspected heatstroke, taking the death toll in the March-June period to 143 from 114.

 Uttar Pradesh is the worst-affected, having reported 35 deaths followed by Delhi (21) and Bihar and Rajasthan (17 each), according to the data.

 Union Health Minister J P Nadda on Thursday asked officials to visit Central hospitals till the heatwave conditions persist to see if separate arrangements have been made for affected patients and also to assess the number of deaths due to heatstroke over the last few days.

 Swathes of northern and eastern India have been in the grip of a prolonged

heatwave, increasing heat stroke casualties and prompting the Centre to issue advisory to hospitals to set up special units to cater to such patients.

Nadda on Wednesday directed that special heatwave units to be set up in all central government hospitals to cater to those falling ill due to the heat. 

He also asked officials to ensure all hospitals are prepared for providing the best healthcare to the affected as he reviewed the situation across the country and preparedness of hospitals to deal with it.
