The author discusses how women have been rendered invisible during the COVID-19 pandemic and how we have experienced a regression in gender biases.

The arrival of the COVID-19 pandemic has triggered the creative use of metaphors, which is particularly relevant in the case of cartoonists.

As the debate on vaccines grows, people with doubts will dissipate them and take a stand for or against them.

Essentially there is no supplement that can prevent the coronavirus, but many patients who have suffered from the coronavirus have vitamin D deficiency.

The virus has spread again in the different populations because we have lowered our protective measures, when we should have maintained them for a much longer period.

Although humans' irresponsible and indiscriminate use of the natural environment could be one of the causes behind the recent coronavirus crisis, bats have been targeted for their role as natural reservoirs of zoonotic pathogens.

The word science has never been as present in the media as it was during the COVID-19 pandemic, and if this continues to be the case in the coming months, it is very likely that something will remain even after the coronavirus disappears.

Embracing an evolutionary perspective thus helps to explain why men and women react differently to certain infectious diseases and to understand (and combat) the strategies of viruses in their relentless evolutionary race to infect and spread among us.

Despite all the achievements in such a short period of time, we must stress that obtaining a drug capable of inhibiting any of the proteases in SARS-CoV-2, or any other pathogenic agent, is a long and complex process that requires the participation of different branches of science.

Every historical period has had its epidemic executioner, and it has almost always been the ecological changes between human communities and the environment that have caused changes in pathogenicity and epidemic diseases.
