Community Transmission

What is community transmission?

According to the World Health Organization (WHO) says community transmission β€œis evidenced by the inability to relate confirmed cases through chains of transmission for a large number of cases.

In the simplest terms, community spread is when we do not know the source of the infection β€” you are unable to trace it back to someone who has travelled in an affected area overseas, or got it through contact with someone who is infected.

What does it imply?

Community spread implies that the virus is now circulating in the community, and can infect people with no history β€” either of travel to affected areas, or of contact with the infected person.

The members of the community who are infected could be circulating that haven't been tagged as infected yet.

When India consider that community transmission has begun?

According to  Ministry of Health and Family welfare  - We can consider that we are in the community transmission stage only when there are about 20 to 30 per cent cases with no clue on how they got the virus.
