Mangaluru, Apr 16: An old refrigerator has been turned into a "disinfection chamber" by researchers who are striving to come up with solutions to tackle the spread of coronavirus.

Dr Arun M Isloor, head of Chemistry Department, National Institute of Technology Karnataka (NITK), Surathkal, along with research scholar Syed Ibrahim has come up with the device which can disinfect items kept inside it.

"We have named this as ZERO-COV," Dr Isloor said.

He says the device ensures 99.9 per cent destruction of microorganisms present on the surface of items.

"We can keep items like vegetables, currency notes, books or envelopes inside the chamber. Switching on the chamber for 15 minutes ensures 99.9 per cent destruction of microorganisms present in the surface of the items," Dr Isloor added.

"Death rate in Karnataka is 1.49 percent, while in Bengaluru is 1.28 percent, and our target is to bring it below 1 percent," Medical Education Minister K Sudhakar told reporters.

"The reason for spike in cases in Bengaluru and other places in recent days is because during the last four months of lockdown we had controlled it very well, but as we relaxed lockdown for economic activities we did not follow certain precautionary measures like distance among other things," he said.

The Minister also conceded that there were lapses on part of the government also in terms of tracing and tracking.

"It has to be improved especially in Bengaluru and we are taking steps in this regard."
