World health officials say the mortality rate for COVID-19 is 3.4% globally, higher than previous estimates of about 2%.

“Globally, about 3.4% of reported COVID-19 cases have died,” WHO Director-General Tedros Adhanom Ghebreyesus said during a press briefing at the agency’s headquarters in Geneva.

World health officials said Tuesday the mortality rate for COVID-19 is 3.4% globally, higher than previous estimates of about 2%.

“Globally, about 3.4% of reported COVID-19 cases have died,” WHO Director-General Tedros Adhanom Ghebreyesus said during a press briefing at the agency’s headquarters in Geneva. In comparison, seasonal flu generally kills far fewer than 1% of those infected, he said.

Death rates for most strains of seasonal flu are .1% or, one-tenth of one percent.

COVID-19 is now 34 times as lethal as the common flu.

The World Health Organization had said last week that the mortality rate of COVID-19 can differ, ranging from 0.7% to up to 15%, depending on the quality of the health-care system where it’s treated. Early in the outbreak, scientists had concluded the overall death rate was around 2.3%. The British medical journal, The Lancet, previously found a lethality rate of 16% in the early portions of the outbreak as clinical resources were overrun and Chinese citizens were left to their own fates, welded inside high rise apartment buildings without food or medicine.

During a press briefing Monday, WHO officials said they don’t know how COVID-19 behaves, saying it’s not like influenza. They added that while much is known about the seasonal flu, such as how it’s transmitted and what treatments work to suppress the disease, that same information is still in question when it comes to the coronavirus.
