One government hospital said it had seen 46 patients suffering from heatstroke this month alone. With more, here's our correspondent, Samira Hussain.

Follow me, we're gonna go into the critical care unit at this emergency ward in this government hospital here in central Delhi.

If you come in, you can see that half of the patients here are actually here because of heatstroke.

I mean, this particular hospital primarily sees day laborers, so these are people that are outside, migrant workers that are in this heat, that are working outside.

They also see a lot of elderly patients who are a lot more susceptible to these kinds of high temperatures.

You know, and there are people just coming in and out of here every minute. This particular hospital has actually built a heatstroke unit, and they have these large baths and ice making machines so they can cool down people's temperatures really quickly.

The head of emergency medicine here told me that just yesterday, for the first time in his career, he's recorded a temperature of 110 degrees in a patient.

Remember that normal body temperature is about 98 degrees, and when temperatures get that high, he said, well, that can lead to multiple organ failure, so it's really dangerous. Now, this hospital over the last two days has seen about two dozen heatstroke patients come in, of which five have died, and that gives you a sense of just how critical the situation is.

Remember, this is just one hospital in the capital of India, as the entire country is dealing with a heat wave.
