The Covid-19 warning was issued by the World Health Organization (WHO) in the context of some countries starting to relax the blockade and social isolation.
AP on April 21, citing WHO Director General Tedros Adhanom Ghebreyesus, warned that "the worst is still ahead" during the Covid-19 pandemic, after the world recorded nearly 2.5 million people infected and 170,000 deaths. casualties.
"Let's stop this tragedy. It is a virus that many still do not understand. ” Mr. Tedros called for, although he did not specify the forecast of disease trends based on what grounds.
Earlier, the WHO Director-General and some experts warned that the situation of Covid-19 epidemic in Africa could be worse because the health system is still limited.
The WHO Director-General made an appeal in the context of a number of European and Asian countries gradually easing their social isolation measures. For example, close schools and limit crowds after the number of infections and deaths from Covid-19 decreases.
Regarding US President Donald Trump's allegations that WHO did not share information "promptly and transparently" when the Covid-19 epidemic broke out in China, Tedros said there was "no secret at WHO because keeping secrets is dangerous, this is a health problem. ”
“This virus is dangerous. It takes advantage of the rift between us when we don't share the same opinion, ”he said.
Virus mutates in many directions
Related to the new strain of Corona virus (SARS-CoV-2) causing Covid-19, the South China Morning Post on April 21 cited research by Professor Ly Lan Quyen and colleagues at Zhejiang University (China). The virus can mutate rapidly and increase toxicity.
The team randomly took samples from 11 patients in Hangzhou to test the virus's ability to bind and kill cells. Results showed that the virus "mutated diversity", including strains can create viral load 270 times higher than the weakest strains.
Another study published in The Lancet found that the virus attacks blood vessels throughout the body and can lead to multiple organ failure.
"This virus not only attacks the lungs, it attacks blood vessels throughout the body," said Frank Ruschitzka at the University Hospital of Zurich (Switzerland), a member of the research team.
This may explain why smokers, pre-existing illnesses that weaken endothelial cells or have unhealthy blood vessels are more likely to become seriously ill when infected with Covid-19, he said.
