Community spreadDate: 22 March 2020 Tags: Disaster & Disaster Management
The government is yet to establish the source of infection of a 20-year-old Delhi resident who tested positive for coronavirus in Tamil Nadu, sending alarm bells ringing and raising questions if this is India’s first case of community transmission of the deadly contagion.
In countries such as Italy or South Korea, the number of Covid-19 cases and related fatalities surged once community transmission of the disease began, making it difficult for governments to contain the rapid spread of the infection.
The ICMR had picked 1,020 random samples of people with severe acute respiratory illness pneumonia and influenza-like symptoms for testing for Covid-19. The results of 500 samples are negative, a sign that community-level transmission of the coronavirus may not be taking place in India still.
If a positive case turns up in these random samples, the ICMR said, it would indicate community transmission and they would enforce localised quarantine and testing measures in the areas from where samples were collected.
The virus that causes COVID-19 seems to be spreading easily and sustainably in the community (“community spread”) in some affected geographic areas.
- Community spread means people have been infected with the virus in an area, including some who are not sure how or where they became infected.
