**2. Pandemic conditions and preventive measures**

This virus spreads mainly from person to person, mainly through the respiratory secretions produced by an infected person when they cough or sneeze. It is possible for these droplets to land in the mouths or noses of nearby people or even to be inhaled into the lungs. Unfortunately, there are no medications that have been tested in controlled studies and have been approved by the FDA for this global pandemic [8]. As a result of prevention measures, cases are being limited as much as possible. The disease must be diagnosed, isolated, and treated early to avoid further spread. The best preventive strategies focus on the isolation of patients and the careful control of infection, including measures to adopt during diagnosis and treatment of an infected patient [9]. A summary of COVID-19 preventive measures is shown in **Table 1**.
