What are the four stages of coronavirus transmission and where India is now:-
According to the Indian Council of Medical Research, India is currently in stage two of the transmission. But some question the numbers.
ICMR says that there are four stages of COVID-19 transmission.
Stage 1: When the disease is just introduced to a population. In India’s case, that is with imported cases – only those with travel history to affected countries tested positive for the infection.
Stage 2: This is the stage that India is at right now, according to ICMR. This is when there is local transmission of the disease – some of those in contact with persons with travel history in turn get infected.
Stage 3: In this stage, there is community transmission i.e. even those who have had no known contact with an affected person, and haven’t travelled to an affected country start contracting the coronavirus disease. According to the Centre for Disease Control and Prevention (CDC), community spread is when “people have been infected with the virus in an area, including some who are not sure how or where they became infected.” This stage makes it difficult to break the chain of transmission, thereby making the disease harder to contain.
Stage 4: The fourth stage is when there is a widespread outbreak, leading it to become an epidemic within the population and difficult to contain.
The World Health Organisation (WHO) in a March 8 release had also called for preparedness for the stages of transmission, although a little different from the ICMR’s categorizations. According to WHO, the first stage is one where there are no cases. The second is when there are sporadic cases – one or more, imported or locally detected. The third stage is when clusters of cases emerge in a time, geographical location and/or through common exposure. And the fourth stage is community transmission, which is defined as “larger outbreaks of local transmission”
