Transmission of coronavirus generally occurs through respiratory droplets and contact. Current evidence suggests that SARS-CoV-2 may remain viable for hours to days on surfaces made from a variety of materials. In the house, care must be taken for open outside doors and windows and the use of ventilating fans to increase air circulation. We recommend using masks to self-protect and to protect others around, during the COVID-19 pandemic, mainly in inside closed spaces as buildings and malls. Also, maintaining distance between each person helps us to control the transmission of coronavirus.
