Field teams, made up of Asha agents and village / neighborhood volunteers, would visit each household. And suspected cases would be referred to doctors for Covid-19 testing.
The state relied heavily on door-to-door fever surveys in the first and second waves due to its strong 2.5 lakh volunteer network. The state conducted the investigation for five rounds during the first wave last year to contain the spread of infection in the community and for the early detection of cases.
Full door-to-door investigations of the first wave identified nearly 32,700 suspected cases and the state put them all for Covid-19 testing.
The state has further stepped up investigations into the fever during the ongoing second wave. The investigations of the second wave itself identified more than 1.55 lakh of suspected cases. These suspected cases are followed up via call center 104 during the second wave.
The state has hired nearly 5,500 doctors in the current second wave to offer teleconsultation services to patients and other suspected cases through its 104 call center reactivated in the second wave. The call center served all suspected 1.55 lakh cases identified in the second wave fever investigations.
Meanwhile, the state has set up helplines at all airports in the state and neighboring states to monitor Covid-19 testing of foreign returnees in preparation for the new Omicron variant. Speaking to ToI, director of the Andhra Pradesh Department of Public Health and Family Welfare, Dr G Hymavathi, said the state was reasonably well prepared for any eventuality or even the third wave.
