The Delta variant of the coronavirus that causes COVID-19, first detected in India, is the one that transmits the fastest, and can take advantage of the relaxation of health prevention measures in many countries to expand, warned the World Organization of the Health (WHO).
“This variant worries us a lot, and is already circulating in 92 countries,” Maria Van Kerkhove, head of the WHO’s anticovid technical cell, underlined at a press conference.
The delta variant now has the opportunity to be transmitted with increased socialization, if the relaxation of the measures is done too early at a time when large populations are still unvaccinated, the American expert added.
Van Kerkhove stressed that, on the positive side, there are no indications that the delta variant represents an increase in mortality among those affected by COVID-19, and that vaccines remain effective against it, at least in reducing cases. serious.
“In any case, it is important to underline that it is necessary to receive two doses of the vaccine to be completely protected,” she also stressed in relation to the delta variant.
Health measures are effective in stopping the transmission of this variant first detected in India, which she in her opinion could mean “that they have to be applied for a longer period of time.”
“It is the fastest variant, and it can easily affect the most vulnerable,” insisted the director of health emergencies at WHO, Mike Ryan.
The director general of the WHO, Tedros Adhanom Ghebreyesus, indicated that global cases of COVID-19 have fallen for eight consecutive weeks and deaths for seven, although the figures are still high (2.5 million infections in the world and 64,000 deaths in the last seven days).
