The unexpected visitor stayed with us

Abstract

By mid-December 2020, an unexpected, unwelcome visitor who stayed on our planet – the SARS-CoV-2 – has caused 74 million confirmed cases of infected people and more than 1,600,000 deaths in the world, mainly in the US, India, Europe and Latin America(1). And it will probably remain with us for many years. A few months ago, Peru was considered the fifth country with the most coronavirus infections in the world and the country with the highest death rate per 100,000 inhabitants(2). However, due to the renewed force of the pandemic in other countries, it now ranks as the 16th country with the most infections, soon to reach one million infected, and with around 37,000 deaths(1).
