Under the sero- survey, the Division will reach out to the community to collect blood samples for the test. The sero-survey involves the testing of blood serum of individuals to detect the history of prevalence of virus on the human body. It is a serological test to check for the prevalence of antibodies on the human body to find whether a person has already been infected by the COVID-19 virus.
About 97 percent of COVID-19 infected in the country are asymptotic. The Division will focus on the areas reporting a higher number of cases in all the seven states. The Division's senior public health office administrator Mahendradhwaj Adhikari said the preparations to launch the survey has reached a final phase.
A total of 315,570 people have undergone the PCR tests, and 17,658 have been tested positive for the virus. The number of recovery cases is 11,695 and the death toll from the virus has reached 40 in the country.
