Coronavirus is tightening its grip and claiming the lives of numerous people across the world. America, particularly witnessed its deadliest day so far due to COVID-19 as states across the nation begin to lift restrictions that were originally implemented to restrict the spread of the virus, according to data published by the WHO (World Health Organization).

An alarming number of people i.e. 2,909 succumbed to the deadly virus in only 24 hours, according to the data, which was collected on Friday, at 4 a.m. (ET). This is the highest daily coronavirus related death toll in the United States until now. This is based on the CNBC analysis of the WHO's daily COVID-19 situation reports.

Until last month, the highest daily death toll in America was 2,471, which was reported on Apr. 23 by the WHO. According to State officials, data on COVID-19 related deaths aren't easy to analyze as they usually include patients that became ill and were under medication weeks ago. WHO representatives didn't respond to CNBC's request for a remark.

America's deadliest day comes when state officials are considering reopening certain parts of the economy and lifting the strict stay-at-home orders. Epidemiologists and public health officials claim that as people get weary of the restrictions and businesses reopen, the virus is likely to spread even in communities that haven't experienced a major epidemic yet.

On Friday, protestors across at least ten states demanded that the government eases the stay-at-home orders, along with a slew of other restrictions that were put in place to restrict the spread of the virus. States that saw protests include Washington, Tennessee, New York, New Mexico, New Jersey, Illinois, Florida, Delaware, Colorado, and California.

A large of states have already unveiled their plans for reopening businesses, while some other states such as Texas, Tennessee, South Carolina, and Georgia have already allowed retailers to provide non-essential items to reopen. With more than 27 percent of all confirmed cases in the United States, according to Johns Hopkins University data, New York state has been hit the hardest by the outbreak.

New York has reported about 24,039, out of the country's 65,173 COVID-19 related deaths, according to Hopkins. This dead toll bears comparison with September 11, 2001, terrorist attacks, wherein 2,973 people were killed in one day, as per a government commission.

The WHO data does not coincide with the data collected by the CDC (Centers for Disease Control and Prevention), which does not report historical daily deaths from coronavirus. The CDC website suggests that 2,349 Americans died of COVID-19 on May 1.
