Coronavirus: ICMR study hints at community transmission in India

The report quoting health experts said that this appeared to be an indication of community spread.

On Friday, Punjab Chief Minister, Amarinder Singh asserted that community transmission appeared to have started in the state. He said that in the wake of the increased number of positive cases, the lockdown and curfew should continue.

He said that the state has controlled the pandemic to some level, but this will spread. We have to keep our contingency plan ready, he also said.

The World Health Organisation says, " community transmission is evidenced by the inability to relate confirmed cases through chains of transmission for a large number of cases, or by increasing positive tests through sentinel samples."

The ICMR study said that COVID-19 positivity among SARI patients has increased from zero before March 14 to 2.6 per cent for the week ending April 2. Between March 22 and April 2, when the COVID testing strategy was expanded to include all SARI patients, 102 of the 4,946 samples tested positive.

The study, however, said that the data of SARI patients pertained to selected sentinel hospitals, predominantly in the public sector ones in urban areas and it may not be representative of the entire district, state or country. However the trend on COVID-19 positivity among SARI patients could provide reliable information about its spread in the area, the report also said.
