Covid-19 is an infectious respiratory disease caused by a newly discovered coronavirus

Mode of transmission

The virus can be transmitted through droplets/aerosols found in our respiratory system (nose and mouth).

Contact and droplet transmission Transmission can occur through direct, indirect, or close contact with infected people through infected secretions or respiratory droplets, which can be expelled when an infected person coughs, sneezes, talks or songs.

Airborne transmission – It’s a spread of an infected agent caused by the dissemination of droplet nuclei(aerosols) that remain infectious when suspended in the air over long distances and time. Airborne transmissions can occur during medical procedures that generate aerosols.

Fomite transmission – Respiratory secretions or droplets expelled by infected individuals can contaminate surfaces and objects, creating fomites (contaminated surfaces)

When can a person infected with SARS-CoV-2 infect others?​

Evidence suggests that SARS-CoV-2 RNA can be detected in people1-3 days before their symptom onset, with the highest viral loads observed around the day of the symptom onset. The duration of positivity generally appears to be to 1-2weeks for asymptomatic persons, and up to 3weeks or more for people with mild to moderate disease.

Preventative measures

  • Wear a mask. Every one should wear a mask in public.
  • Physical distancing. We should stand a 1meter apart especially around people who don’t live with you.
  • If someone in your household is infected, people in the household should take precautions including wearing masks to avoid spread to others
