The COVID-19 pandemic is the coronavirus disease pandemic, that outbreak in Wuhan, capital of the province of Hubei in central China, where it was first identified, in . SARS-CoV-2 virus is responsible for the disease.
The name was chosen by the WHO after genomic sequencing revealed a strong similarity, around 70%, with the SARS-CoV virus, responsible for the first coronavirus pandemic in . Also WHO, after defining the Wuhan episode as a public health emergency of international concern on , declared pandemic on . Since the early Wuhan cases, more than thirteen million people have contracted the disease in over 180 countries, causing over half a million deaths worldwide.
Disease transmission occurs between people while they are in close contact, very often through the inhalation of saliva droplets, produced when speaking, coughing or sneezing. These droplets end up depositing on the ground or on surfaces, where the virus can resist for many hours, and which can transmit the disease by touching them with your hands and then with these touch your face or eyes.
More recent studies, as Identifying airborne transmission as the dominant route for the spread of COVID-19, published last , have shown how, in addition to droplets, the virus can also be transmitted through the air by aerosol, especially in closed environments, where the particles can remain in suspension for several hours.
The main symptoms are: fever, cough, weakness, shortness of air and loss of smell. Pneumonia, thrombosis, kidney and liver, nervous system and heart damage can occur as major complications. It has been verified that some of these problems can become permanent, that is, they persist in technically healed patients, such as loss of smell, shortness of breath, sense of weakness and various neurological problems, both to the brain and the nervous system.
