AGE AND SARS-COV2 INFECTION
Th e beginning of 2020 was marked by the emergence of the 2019 COVID-19 pandemic (Corona Virus Disease from 2019) caused by the new corona virus, SARS-CoV-2 (also known as new CoV, 2019-nCoV or COVI-19), a name derived from the syndrome name, i.e. Severe Acute Respiratory Syndrome, which fi rst appeared in China at the end of 2019 (1) and then spread rapidly around the world. So far, the animal from which the SARS-CoV-2 was transmitted to humans is not known yet with certainty. In addition to the previously known MERS-CoV and SARS-CoV, which can cause severe clinical presentation (Middle East Respiratory Syndrome and Severe Acute Respiratory Syndrome), four other human coronaviruses (229E, NL63, OC43 and HKU1) have been shown to cause infection only in the upper respiratory tract and cause relatively minor symptoms. SARS-CoV-2 has the ability to infect and actively reproduce in the upper respiratory tract.
