With simply 5% of the world’s inhabitants, South America had a per capita loss of life charge that was equal to eight occasions the world quantity.

However that may be a factor of the previous.

On the finish of June, the variety of infections started to say no steadily, turning the area right into a one of many areas of the world the place the pandemic appears to be higher managed.

Thus, whereas for this Monday the weekly common of confirmed instances per 100,000 inhabitants was 52 in the UK and 43 in the USA, Brazil solely reached 8, Argentina to six and Colombia to three, based on figures from Our World in Information.

This lower in infections has been key for South America to be at present one of many areas of the world that’s registering fewer instances of covid-19.

However how do you clarify this abrupt drop in infections in South America?

Between immunity and different unknowns

“The very first thing I might say to you is that I consider that we’re not totally clear”, Responds Andrés Vecino, researcher in well being programs on the Division of Worldwide Well being of the John Hopkins College of Public Well being (United States).

The researcher remembers that this isn’t the primary time that there was a lower in instances that appears to announce that the tip of the pandemic is approaching after which there’s one other wave of infections that reveals that it was not.

“You will need to say that we do not know precisely what that is and that the truth that instances are falling now doesn’t imply that it’s going to occur sooner or later. I wish to bear in mind what occurred in India, the place there was a comparatively low rely of instances for its inhabitants after which we noticed a big improve in instances with the delta variant, “the knowledgeable warns BBC Mundo.

GETTY IMAGES In latest months, South American international locations have made progress in vaccinations.

Dr. Carla Domingues, who led Brazil’s immunization program till 2019, lately issued an identical warning. “It’s a phenomenon that we have no idea tips on how to clarify,” mentioned this epidemiologist to the newspaper The New York Instances.

Nevertheless, specialists give some clues: amongst them, vaccination. South American international locations have accelerated the speed of inoculations in latest occasions, one thing that based on many specialists might have contributed to curbing infections.

Vecino agrees, however doesn’t level solely in the direction of vaccines however, extra broadly, to the immunity acquired by the inhabitants of the area each by injections and infections.

“I believe there is kind of consensus that it’s potential that the discount in instances in South America could also be associated to some extent of immunity within the inhabitants,” he highlights.

The knowledgeable explains that the completely different vaccines which have been utilized within the international locations of the area are an essential component to contemplate, as is the immunity achieved by those that have already had the an infection.

“Many individuals in a few of these international locations have been contaminated. A latest research they did in 12 cities in Colombia reveals that the 89% of the individuals in these localities have already been contaminated. With that one begins to suppose that it’s potential that in some locations there are such excessive ranges of an infection that we’re already starting to see a discount within the illness, ”says the knowledgeable.

Vecino warns that, for the reason that inhabitants isn’t homogeneous, this information can’t be interpreted as that 9 out of 10 those who one meets on the streets of these cities already had covid-19, so it’s not essential to belief.

“People are associated in teams, then there could also be teams of people that, for instance, haven’t but been contaminated or vaccinated and these teams of individuals can have outbreaks if, for instance, a extremely transmissible variant resembling mu, resembling delta or gamma arrives, the three which can be already in Latin America, to allow them to clearly trigger a rise in instances and deaths, ”he explains.

“Having mentioned that, it’s potential that the extent of immunity acquired by vaccines and former an infection is among the the reason why we’re seeing much less transmission at the moment,” he provides.

Making use of the suitable measures

Ciro Ugarte, Director of Well being Emergencies of the Pan American Well being Group (PAHO), confirms that there was a lower in instances and deaths in virtually all South American international locations, apart from Venezuela.

Ugarte explains that PAHO is working with the ministries of Well being and with specialists within the area to review these developments, in addition to the the reason why this decline has continued, and factors to the tightening of management measures after the numerous improve of instances within the area between the tip of 2020 and the primary months of 2021.

International locations carried out a lot stricter measures Concerning bodily distancing, the motion of individuals, the necessary use of masks, they began vaccination and prolonged it to different teams, primarily those that have been at higher threat. All of this could partly clarify this pattern, ”Ugarte says in response to a BBC Mundo question.

The director, nevertheless, warned the area in opposition to changing into complacent.

“We have now seen that when the instances lower it’s as a result of we’re doing issues nicely. In different phrases, we’re implementing public well being measures which have been confirmed again and again that they proceed to serve, ”he highlights.

“The worst factor that would occur to us and that would occur to the international locations of South America is that now that they’re with fewer instances chill out the measures as a result of that may be a nice alternative for the virus to be transmitted from individual to individual ”, he warns.

GETTY IMAGES PAHO urges the international locations of the area to keep up precautionary measures to keep away from contagion.

Thus, though the variety of instances is low for the time being, Ugarte considers that the suitable factor is to not decrease our guard:

“Our suggestion to your entire inhabitants of South America who’s seeing that transmission is reducing is to take note of that we’re in that section as a result of the suitable measures have been taken. Let’s not chill out them ”. (I)
