A couple in the Indian state of Chhattisgarh have named their newborn twins Corona and Covid.

The twins — a boy and a girl — were born during the ongoing 21-day long nationwide lockdown that began on March 24.

“The delivery happened after facing several difficulties and therefore, my husband and I wanted to make the day memorable,” Preeti Verma, the 27-old mother of the twins, told news agency Press Trust of India.

The couple said the names would remind them about the hardships they faced during the lockdown and ahead of the successful delivery in a government hospital last week.

The lockdown in India has resulted in the suspension of trains and airline services and effectively kept 1.3 billion Indians at home for all but essential trips to places like markets or pharmacies.

India has 2,909 confirmed cases of the coronavirus across the country, including 68 deaths.

The overall number of known cases in India is small compared with the United States, Italy and China, but health experts say India could be weeks away from a huge surge that could overwhelm its already strained public health system.
