Even the fully vaccinated should continue to wear masks, warns o World Health Organisation, in order to slow the spread of the Delta variant of COVID-19.
Although several countries (including the US) have eased mask requirements in recent weeks, the WHO warns that new, highly contagious variants of the coronavirus could be a major problem.
The Delta variant of COVID-19 is one of the most recently observed, but also one of the most worrying for scientists. Cases are increasing in the US and since last weekteam, 1 in 5 recent coronavirus cases were from the Delta variant, according to the CNBC.
According to forecasts of the US Centers for Disease Control and Prevention, the Delta variant is poised to become the second most prevalent type of COVID-19 in America in the first half of June.
Current mRNA vaccines being developed in the US by Pfizer and Moderna are believed to be effective against the Delta variant. However, World Health Organization officials warn that the growing prevalence of the variant means that even vaccinated individuals should not leave the masks.
"People can't feel safe just because they did it two doses", says Dr Mariangela Simao, of the WHO. "They must continue to protect themselves."
The vaccine will not stop the spread of COVID-19. Although it works as designed (to reduce the severity of symptoms and overall impact of coronavirus infections, thereby dramatically reducing the chance of hospitalization or death) immunization will not occur. The vaccine simply reduces the chance that something serious will occur damage.
"People need to continue to use masks consistently, to be in ventilated areas, and to be careful with hand hygiene," added Dr Simao. if you have been vaccinated while the virus continues to be transmitted. ”
So the WHO is appealing to those who have already been vaccinated to continue wearing a mask when circulating in public. This way, people who have not been vaccinated will be at less risk. It is not just altruism that can motivate. If variants of COVID-19 allow it to spread faster, there is a chance that they will mutate further and become even faster, with unpredictable effects even on those who have been vaccinated.
