Sri Lanka: Suicide bomber's family also killed in blasts

The coronavirus pandemic has sickened more than 2,425,000 people, according to official counts. So far at least 164,000 people have died, and the virus has been detected in at least 177 countries, as the following table shows.

Jun 9: The World Health Organization says it still believes the spread of the coronavirus from people without symptoms is “rare,” despite warnings from numerous experts worldwide that such transmission is more frequent and likely explains why the pandemic has been so hard to contain.

Maria Van Kerkhove, WHO''s technical lead on COVID-19 said at a press briefing on Monday that many countries are reporting cases of spread from people who are asymptomatic, or those with no clinical symptoms.

But when questioned in more detail about these cases, Van Kerkhove said many of them turn out to have mild disease, or unusual symptoms.

Although health officials in countries including Britain, the U.S. and elsewhere have warned that COVID-19 is spreading from people without symptoms, WHO has maintained that this type of spread is not a driver of the pandemic and is probably accounts for about 6 per cent of spread, at most.

Numerous studies have suggested that the virus is spreading from people without symptoms, but many of those are either anecdotal reports or based on modeling.

Van Kerkhove said that based on data from countries, when people with no symptoms of COVID-19 are tracked over a long period to see if they spread the disease, there are very few cases of spread.

“We are constantly looking at this data and we''re trying to get more information from countries to truly answer this question,” she said. “It still appears to be rare that asymptomatic individuals actually transmit onward.”

May 15: Global deaths linked to the novel coronavirus passed 300,000 on Thursday, while reported cases of the virus are approaching 4.5 million, according to a news agency tally.

About half of the fatalities have been reported by the United States, the United Kingdom and Italy.

The first death linked to the disease was reported on January 10 in Wuhan, China. It took 91 days for the death toll to pass 100,000 and a further 16 days to reach 200,000, according to the Reuters tally of official reports from governments. It took 19 days to go from 200,000 to 300,000 deaths.

By comparison, an estimated 400,000 people die annually from malaria, one of the world’s most deadly infectious diseases.

The United States had reported more than 85,000 deaths from the new coronavirus, while the United Kingdom and Italy have reported over 30,000 fatalities each.

While the current trajectory of COVID-19 falls far short of the 1918 Spanish flu, which infected an estimated 500 million people, killing at least 10% of patients, public health experts worry the available data is underplaying the true impact of the pandemic.
