Report on Keralites Tested Positive Outside Kerala
As the first case of COVID19 got detected in Kerala, the Surveillance Unit of Directorate of Health Services was alert to identify the
cases and their contacts. Whenever any contacts are found to be of other states, that information was shared with the respective
States. Eg the family came from Italy later got detected positive, the inmates of the flights from other states was informed to them.
When the cases started getting detected in other states, the surveillance unit was active to identify the cases getting detected
outside Kerala. This was important from the point of view of doing contact tracing here and ensure that the infection source, if it is in
Kerala, the containment is possible.
Among the line list from NCDC Portal, a total of 110 persons were tested outside Kerala and found positive as on 30th June 2020. Out
of these 3 were duplicate entry and are excluded from the report.
Out of total 107, a total of 96 persons could be studied and it is deduced from the field investigations, the departure time study that 90
persons have not contracted virus in Kerala and the 6 persons have possible chances of got infected in Kerala.
The Department of Health and Family Welfare is further examining the six cases areas regarding number of positive cases and the
time period of the symptomatic positives. The teams have been asked to do further back series studies to see whether there were
more cases during the same time period. It is also instructed to do more testing in these panchayaths to see whether there is an
active infection source in the localized areas.
