TOPLINE WHO Director-General Tedros Adhanom Ghebreyesus on Monday issued a dire warning about the new variants of Covid-19 that are emerging across the globe, noting that because those variants can be more contagious, the surge in cases they’re likely to cause could further stress hospitals and health workers already stretched to the brink.
KEY FACTS
During a press briefing Monday, Ghebreyesus said that more contagious variants of the coronavirus “can drive a surge of cases and hospitalizations, which is highly problematic for health workers and hospitals already close to the breaking point.”
The added strain on hospitals puts other essential health services at risk, he added, meaning that critical surgeries or procedures may become more difficult because hospital resources are more limited.
While these variants have been found to be more contagious, experts say they don’t appear to cause more severe sickness or increase the risk of death.
Dr. Tom Frieden, a former director of the Centers for Disease Control and Prevention, warned last week that the U.S. is “close to a worst-case scenario” because of the rapid spread of a new, highly contagious strain of Covid-19.
KEY BACKGROUND
New variants of Covid-19 have been found in the United Kingdom, the United States (where 63 cases have been detected), Canada, South Africa, and Nigeria, among other countries, the CDC says. Japan’s health authorities announced over the weekend that they had detected a new variant of the virus in four travelers from Brazil, Reuters reported.
WHAT TO WATCH FOR
Scientists are keeping track of new mutations as they emerge and studying how they will impact the effectiveness of vaccines. “I’m quite optimistic that even with these mutations, immunity is not going to suddenly fail on us,” Jesse Bloom, an evolutionary virologist at the Fred Hutchinson Cancer Research Center in Seattle, told the healthcare publication STAT. “It might be gradually eroded, but it’s not going to fail on us, at least in the short term.” A recent study from the University of Texas and pharma giant Pfizer found that Pfizer’s Covid-19 vaccine is still effective in protecting against new variants of the virus.
