What Are Different Stages Of Coronavirus Outbreak?
Indian Council of Medical Research (ICMR) said that India was at the second stage of coronavirus pandemic. At this stage, there’s no fear of community transmission.
Stage 2 of coronavirus outbreak
ICMR Director General Balram Bhargava explained that India was on Stage 2 of the outbreak and not on Stage 3 where there was fear of community outbreak. Also, Mr. Bhargava hoped that Stage 3 would never arrive in India.
He further said that preventing the outbreak from reaching to Stage 3 depended on India’s response like closing borders and proactive stage. But he said that it was difficult to say that community transmission won’t happen.
Different stages of an outbreak
Stage 1: Transmission is imported from foreign nations through air traffic.
Stage 2: Local transmission starts after people start coming into contact with affected persons. For example, family members, friends, neighbors and colleagues of infected persons are tested positive for the infection.
In local transmission, the virus spread remains limited to certain pockets. Since its source is visible, it is easier to contain the virus at this level as opposed to community transmission.
Stage 3: It is the stage of community transmission where people start getting infection even without coming into contact with infected persons or getting exposed to infection.
At this stage, it becomes very difficult to track source of infection. Italy and Spain are in the Stage 3 of coronavirus spread.
Stage 4: It is the worst stage where disease becomes an endemic and there seems no end point. China is at the Stage 4 of COVID-19.
