Passengers travelling from these countries will be required to provide documentation of their COVID negative report before being permitted to leave the airport, according to the state's amended requirements.

The Karnataka state government has just made home quarantine required for seven days for travellers arriving at the Bengaluru airport from six countries

China, Thailand, Hong Kong, Japan, South Korea, and Singapore. This measure comes in response to an increase in COVID instances in other nations. Meanwhile, the Center has already said that RT-PCR testing will be required for persons travelling from high-risk nations.
According to Karnataka's updated requirements, travellers arriving from these countries must present a COVID negative report before leaving the airport grounds. Furthermore, if any overseas travellers from the aforementioned nations are discovered to be symptomatic, they will be quarantined promptly and sent to the authorised medical institution, according to the instructions. In the meanwhile, their samples should be collected and sent for RT-PCR testing and genome sequencing.
Asymptomatic passengers, on the other hand, will be allowed to leave the airport but will be advised to self-monitor their health for COVID symptoms and strictly follow COVID appropriate behaviour, such as wearing face masks, maintaining social distance, practising hand hygiene, and remaining under home quarantine for the next seven days.
If they experience symptoms such as a cough, cold, fever, body ache, loss of taste and smell, trouble breathing, or diarrhoea, they must self-isolate and report to the local monitoring team for testing.
