Several international passengers who travelled with negative Covid-19 reports have been found positive for the pathogen when tested on arrival at the international airport here, airport sources said.
Cases of international passengers being found positive in tests conducted at the airport despite having a negative report were being reported on a regular basis, they said. Confirming that such cases had been noticed, Union Health Ministry official Anuradha Medoju here said that the information on positive cases was shared with state government officials for quarantining and other purposes.
"A few cases (of Covid-19 positive on arrival) are reported in spite of them carrying negative report...," she told PTI.
The official, however, said that she does not have details immediately on the number of such passengers. State health officials could not be reached for their comments.
Airport sources said that those arriving from the Middle-East and the UK are tested mandatorily, while passengers from countries like the US, Singapore and Maldives are allowed to go home if they carry a negative RT-PCR report of 72 hours.
While it was doubted that some might be faking their test reports in order to travel, the airport sources said in the case of positive results on arrival, it could be due to the quick incubation of the virus (during the journey). It was also possible that a person might be tested negative for some reasons before the journey despite him carrying the virus in reality.
