"Even countries that have demonstrated the ability to suppress transmission of Covid-19 must remain alert to the possibility of a resurgence" of the virus, warned WHO Director-General Tedros Adhanom Ghebreyesus. “Last week, China reported a new outbreak in Beijing, after more than fifty days without any cases in this city. Over a hundred cases have now been confirmed. The origin and extent of the epidemic are under investigation ”, he added. Responsible for managing the pandemic at the UN agency, Maria Van Kerkhove said that no deaths have been recorded so far.
SARS-CoV-2, the pathogen behind Covid-19, appeared to be almost eradicated in China, where it appeared in late 2019 in Wuhan, in the center of the country. Until an outbreak was spotted in the capital last week. This rebound in disease has led to new confinements of residential areas and additional screenings. Sports and cultural sites have also been closed.
US withdraws emergency authorization for hydroxychloroquine
U.S. health officials on Monday withdrew permission to use two treatments against Covid-19, chloroquine and hydroxychloroquine, a drug that was previously championed by President of the United States, Donald Trump.
"It is no longer reasonable to believe that oral administration of hydroxychloroquine and chloroquine is effective in the treatment of Covid-19", Denise Hinton, chief scientist of the United States Medicines Agency (FDA), said in a letter. "Nor is it reasonable to believe that the known and potential benefits of these products exceed their known and potential risk", she said, announcing the end of their emergency use.
The FDA had given the green light on March 30 so that these antimalarial treatments were prescribed, only in the hospital, to patients contaminated by the new coronavirus. Trump then had high hopes for hydroxychloroquine, the effectiveness of which against Covid-19 has never been rigorously demonstrated.
"There is a good chance it can have a huge impact. It would be a gift from heaven if it worked. ”, he said in particular. The Republican President himself later received preventive treatment with hydroxychloroquine for two weeks. But FDA warned April 25 of using two antimalarials "Outside of a hospital or clinical trials because of the risk of heart rhythm disorders".
The United States, which had recorded 382 additional deaths from the virus on Sunday (the lowest daily toll for several weeks), continues to register some 20 new cases of contamination every day.
India to reconfigure the big city of Chennai
In India, where containment has been largely relaxed since early June, the epidemic shows no sign of ebb; many patients die after being denied hospital treatment due to lack of beds, local media reported. The country has recorded nearly 9 deaths and bodies are piled up in morgues because the staff of cemeteries and crematoriums cannot keep up with the rate of deaths.
Faced with the deteriorating situation, the state of Tamil Nadu in the south of the country on Monday ordered the reconfiguration of the agglomeration of Chennai, which has more than 15 million inhabitants, from Friday until the end June.
In neighboring Pakistan, the government has warned that the number of cases could double by the end of June and exceed one million by the end of July.
