The serological survey in Delhi will begin today and it will be carried out jointly by the National Centre for Disease Control (NCDC) and Delhi Government. Training of all the concerned survey teams was completed on Thursday.
Two age categorizations have been set to conduct the survey, one is for below 18 years of age group and another for above 18 years.
Depending upon the level of sero-prevalence of infection, appropriate public health interventions can be planned and implemented for prevention and control of the disease.
As per the Indian Council of Medical Research, periodic sero-surveys are useful to guide the policy makers to conduct surveys in high risk areas or vulnerable population who have been infected in the past and has now recovered.
The survey will involve collection of blood samples from randomly selected individuals. Blood samples will be collected for detecting IgG antibodies and it would be conducted using an IgG ELISA kit.
