The low incidence of the virus in the Islands is not related to the weather

It should be remembered that the second wave of this global pandemic broke out in the middle of August, when temperatures were very high. In fact, the accelerated spread of the virus led the Canary Islands to tighten restrictions and record its worst data a few weeks later, reaching a daily record of 382 infections on September 4. Just 24 hours earlier, the region had added 381.

The panorama puzzled the experts. And it is that there were many who endorsed that SARS-CoV-2, like other coronaviruses, would not have the ability to resist heat and, therefore, would not wreak havoc in summer. However, once again, the pathogen showed that its behavior is unpredictable.

“High temperatures do not stop the virus, but with cold people occupy more closed spaces”

Based on the criteria of the head of the Epidemiology and Prevention section of the General Directorate of Public Health of the Government of the Canary Islands, Amós García Rojas, the summer showed that the heat does not help to contain the spread of the disease. “The only seasonal factor that can influence is that, when it is cold, people tend to occupy more closed spaces, which favors the transmission of the infection. However, the temperature as such does not stop this new coronavirus ”, indicates the doctor.

Likewise, as detailed, the episodes of haze that often affect the community do not influence the evolution of the pandemic either. “There is no logical relationship that allows us to understand that the dust in suspension can have a positive or negative influence on the problem”, adds the specialist. “What we do know,” he continues, “is that the good data we handle is associated with the good behavior of the general public, the excellent work being done by the trackers and the proper functioning of the health system.”

Regarding whether the arrival of winter could increase the risk of coinfection between influenza and Covid-19, the expert is blunt in saying that, “the influenza virus is seasonal and always has a greater presence in winter , unless the response to the vaccination campaign is as important as the one we are having. If we add to this compliance with all security measures, we can ensure that there are hardly any cases of the flu “.

According to García Rojas, the evolution of the SARS-CoV-2 pandemic in the Islands can be described as “favorable”, taking into account that the difficult situation that many autonomous communities are going through has been decisive in decreeing a new state alarm. “We have an incidence that, within the context we are experiencing, is more than acceptable. We must bear in mind that, if we want to preserve it, we must insist on maintaining correct hand hygiene, interpersonal distance and the use of masks ”, emphasizes the section chief.

In this sense, the epidemiologist defends that the only instrument that will allow modulating the spread of the pathogen will be the vaccine. Until then, it is advisable to be alert and not lower your guard. “Bad decisions can throw all advances overboard,” he highlights.

Given this reality, it highlights that a large part of the Covid-19 outbreaks are being detected in meetings between friends or family. A fact that leads him to appeal to prudence and responsibility. “Even if we are with people who are part of our narrower circle, it is important to respect physical distance and use masks. The Christmas period is approaching and, of course, it will not be a holiday like the ones we have had so far. We are living in an exceptional situation and we all have to collaborate to end this conflict as soon as possible, ”García Rojas says.
