Delta variant and slow vaccination

09 Aug

The delta variant of covid 19 has lit a warning around the world that the pandemic may not yet be under control. In Brazil, the recent Oswaldo Cruz Foundation Bulletin (FioCruz) states after a study that there is a dangerous combination, high Delta contagion and slow vaccination .

The risk of the explosion of a new wave of contamination and infection is worrying, the study points out that Brazil already has 435 confirmed cases of the Delta variant and in 19 states the levels of contamination are dangerous despite being declining.

In an interview with CNN, last Friday (08/06), deputy director Jarbas Barbosa of the Pan American Health Organization (PAHO) warned that confirmed cases of the Delta variant in Brazil are just the “tip of the iceberg” and highlighted the importance “that the vast majority of cases of the variant are asymptomatic or mild, which do not realize and are not tested”.

We cannot relax prevention and isolation measures, recalled Jarbas Barbosa, in the cases of Chile and Uruguay that after relaxing measures had a new wave of infections, although Uruguay announced a weekend without deaths for the first time.

The contagion comparison made with the Delta variant is didactic, as contagious as chickenpox, can cause more severe symptoms than the previous variants and are also transmissible among vaccinated, according to the US Centers for Disease Control and Prevention ( CDC), in an article published in The Washington Post, in a note signed by Maíra Menezes, the Fiocruz postcard also warns of the danger of this variant.

Vaccination is important, which is still slow, the current numbers are close to 45 million for the two doses and 100 million for the first dose, it is possible to accelerate and as there is still no explosion of the Delta variant in the country, if combined with preventive measures, we can prevent a new wave of infections, hospital overflows and deaths.

Both infections and deaths that fall slowly in Brazil have a tendency towards stability with a slight increase, it is too early to say that it is the Delta variant, but a policy of testing and prevention would be important, researchers of Fiocruz warns of the lack of a plan B.
