The first sero-survey conducted on July 11 indicated infection among 1.41% people who had subsequently developed antibodies. Antibody prevalence rose to 5.1%, suggested the 2nd survey conducted on August 28.
It takes at least 2-4 weeks to develop antibodies. So, the recent survey corresponds to the infection status before 3 weeks. If another survey is conducted now, it will further show positive results, said Pati.
Sero prevelance is more than 60% in five wards. 28% of the people from Ward No-55 and over 63% people in Ward No.16 have developed antibodies. This apart, another positive aspect of the survey is that 90% people had no major symptoms.
However, the 50% who are still not infected are vulnerable to the lethal virus.
