Bengaluru, Apr 5: The COVID-19 related lockdown has substantially improved the air quality of Bengaluru, taking it from satisfactory level to good, a senior state pollution control board offcial said here on Sunday.

It is between zero to 50 AQI (Air Quality Index) now. We have good quality air," the Karnataka State Pollution Control Board member secretary Basavaraj Patil told PTI.

He said the indicator for knowing the air quality in

"If the AQI is zero to 50 then it is good. If it is 50 to 100 then it is satisfactory. 101 to 150 is moderate and if it is 151 to 200, then it is poor, he explained.

Patil said as per available recrods, there has been a 60 to 65 per cent reduction in pollution during the lockdown.

The city railway station and Peenya industrial area, which used to be among the areas with highest AQI, has seen pollution levels come down significantly, he said.

Another major contributor of pollution was construction activities, which too had ground to a halt due to the lockdown, resulting in zero dust emission.

Patil opined that the improved air quality would boost the immune system of the people.

Bengaluru, May 7: Karnataka has revised its standard operating procedure (SOP) for international passengers. The first group of passengers will arrive in the state on May 8.

The number of categories has been reduced to two from three. Category A includes passengers symptomatic on arrival while Category B passengers are those asymptomatic on arrival. These are passengers who are either healthy or those having co-morbidities.

As per the revised SOP, the passenger will be released on the seventh day, if tested negative, to strict home quarantine for another seven days with stamping.

This norm is in contradiction to the Ministry of Home Affairs’ SOP for international passengers. As per the MHA’s SOP, the passengers (asymptomatic) will be under institutional quarantine for 14 days. Testing negative after 14 days, they will be allowed to go home and will undertake self-monitoring of their health for 14 more days.

On the contradiction, Pandey said, "We don't take chances as we rely on tests instead of just quarantining. Other states may be depending on just 14-day institutional quarantine."

"GOI SOP doesn't talk about Covid tests on international passengers. We have put an additional safety layer of three Covid tests on returnees -- one on arrival, second from 5-7 days and last on 12th day. This will ensure definite identification of positive cases even if they are asymptomatic and their subsequent treatment. We should look at the spirit behind the order," he added.

On the 14-day additional reporting period for category B, he said, "It is implied as category B patients should report to us for 14 days after their first 14-day quarantine period is over."

Medical Education Minister Dr K Sudhakar said that the State would follow the Centre’s norms.

Till Tuesday, Karnataka’s SOP had three categories. Under Category A (symptomatic), 14-day institutional quarantine at COVID-19 Health Care Centre was mandatory followed by 14-day reporting period. Under Category B (asymptomatic above 60 years with co-morbidities), seven-day institutional quarantine at hotel/hostel followed by seven-day home quarantine and 14-day reporting period had been recommended. The 14-day home quarantine and 14-day reporting period was mandatory for Category C (asymptomatic).
