WHO says coronavirus death rate is 3.4% globally, higher than previously thought – millions of potential deaths in models?

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. The World Health Organization had said last week that the mortality rate of COVID-19 can differ, ranging from 0.7% to up to 4%, depending on the quality of the health-care system where it’s treated. Early in the outbreak, scientists had concluded the death rate was around 2.3%.

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. “This is a unique virus, with unique features. This virus is not influenza,” Tedros said Monday. “We are in uncharted territory.”

Dr. Mike Ryan, executive director of WHO’s health emergencies program, said Monday that the coronavirus isn’t transmitting the same exact way as the flu and health officials have been given a “glimmer, a chink of light” that the virus could be contained. “Here we have a disease for which we have no vaccine, no treatment, we don’t fully understand transmission, we don’t fully understand case mortality, but what we have been genuinely heartened by is that unlike influenza, where countries have fought back, where they’ve put in place strong measures, we’ve remarkably seen that the virus is suppressed,” Ryan said. –CNBC

Frightening numbers showing up in the latest models: Boston — The coronavirus death toll now tops 3,000 worldwide, with nearly 90,000 cases. But even those numbers are nothing compared to what could happen in the months ahead. CBS News spoke to one of the country’s top experts on viruses, Marc Lipsitch from Harvard University, who cautions that 40-70% of the world’s population will become infected — and from that number, 1% of people who get symptoms from COVID-19, the disease caused by the coronavirus, could die. The virus can spread rapidly and people can transmit it before they know they are infected. Lipsitch breaks down his findings in this extended conversation with CBS News. The following transcript has been lightly edited for clarity.  –CBS News

The implication of a global pandemic infection as Marc Lipsitch modeled it, generates numbers too staggering for most people in the world to even process. A global population of 7.8 billion people (as of March 2020) at even a 50% infection rate would be 3.9 billion people times a 3.4% mortality rate would be 132 million people could potentially die. This is COVID-19  nightmarish scenario is altogether both unthinkable and unfathomable.
