COVID-19 Delta variant has potential to ‘dramatically curve the epidemic’


Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization.Who is the) Tell Journalists have been briefed regularly that deltas have been identified in at least 85 countries and that they are “spreading rapidly among the vulnerable population”.

“With some countries facilitating public and social health measures, we are starting to see increases in transmission around the world,” he said.

According to the head of the World Health Organization, the significant increase in the number of cases translates into more hospitalizations, which continue to stress health care workers and health systems while putting more people at risk of death.

He acknowledged that new variants are expected, saying “that’s what viruses do, they evolve” and stressing that by preventing transmission, we can stop variants from appearing.

“It is very simple: more transmission, more variables. Less transmission, fewer variables,” Tedros explained, stressing that it is urgent today to prevent transmission through the constant use of health and social measures along with vaccines.

“This is why the World Health Organization has been saying for at least a year that vaccines should be distributed equitably, to protect health workers and the most vulnerable,” he said.

“exponential” curve

Maria Van Kerkhove, Technical Leader of the World Health Organization COVID-19“The global situation is very fragile,” he said, and “countries must be careful.”

Noting that Delta has proven to be “highly contagious in any country it reaches,” she warned that it is transmitted between unvaccinated people, “even in countries with high rates of immunization.”

“The delta variable can make the epidemic curve exponential,” Dr. Van Kerkhove added.

“Constellation of Variables”

But Delta isn’t the only worrisome boom. According to the WHO expert, “there is a constellation of circulating variables”, including sub-variables, four of which are very worrying.

“Vaccines and treatments work, but these viruses can evolve,” she said, and existing shots “may not work” over time, emphasizing again that to reduce outbreaks, everyone must continue to maintain public health measures.

Emergency response

One of the most important ways the WHO coordinates the response to COVID-19 and other emergencies is through its global network of Emergency Medical Teams (EMTs).

When crises strike, WHO mobilizes these health professionals to support national responses, treat patients, provide training and oversight, and ensure standards of quality care.

“Globally, WHO has certified teams from 20 countries that have gone through a rigorous quality assurance process to ensure they meet internationally agreed standards,” Tedros said, adding that another 87 countries are either in the process of obtaining WHO certification, or are developing quality assurance systems on their own. national level.

Since the start of the pandemic, he said, the WHO has helped deploy more than 108 EMTs and international experts around the world.

new standards

Last week, the World Health Organization and its partners published new EMT dissemination standards for a range of situations, “from natural disasters to epidemics and conflict situations,” the head of the UN agency said.

“This represents a major step forward in ensuring that emergency medical teams meet the common standards for quality of care, whether they are deployed nationally or internationally,” he said.
