After 6 infectees, Mumbai airport ‘segregates’ passengers from ‘high-risk’ countries

Published

on

In view of the threat from Covid-19 variant Omicron, the Chhatrapati Shivaji Maharaj International Airport on Wednesday started segregating passengers arriving here from the ‘high-risk’ countries, after six were found infected in the past few days, an official said.

The new exercise was implemented after six international passengers have tested positive for Covid-19, including two from South Africa and the rest from other high-risk countries in the past few days.

According to a state government official, one each was found positive in Mumbai, Kalyan-Dombivali and Mira-Bhayander, while one is from Pune and two others from Pimpri-Chinchwad.

Though all have tested positive, they are asymptomatic or displaying mild symptoms, but their samples have been sent for genetic sequencing and their contact tracing has been taken up.

As per the current guidelines, all passengers arriving from Europe and 11 other nations will be tested and samples of those found positive will be sent for genomic sequencing.

Those found negative shall also undergo quarantine for seven days before testing again, and random tests on 5 per cent of all passengers landing here shall be conducted with positive reports to be sent for genetic sequencing.

The CSMIA has also made adequate RT-PCR testing facilities at 48 registration counters and 40 sampling booths for international arrivals.

Besides three labs have been set up — Lifenity, Suburban Diagnostics and Acu-MDx (Mylabs) for the testing purposes.

Besides the existing regular RT-PCR, 30 Rapid PCR machines are made available for the passengers intending to catch connecting onward flights with short gaps, and the facilities shall be upscaled further if required.

For those passengers who have not pre-booked online RT-PCR tests, QR codes are displayed at various locations in the arrival corridor.

Physical forms for RT-PCR registration are available to the passengers on board which they can fill up before disembarking from the flight to avoid queues on arrival.

“The CSMIA has undertaken all necessary precautions to mitigate the spread of the new covid variant. For CSMIA, passengers safety, well-being, and security is of utmost importance,” said a spokesperson.

Tale of Mumbai’s rising trend of air pollution

Published

By

Every winter, smog-filled days and nights across entire north India are a common thing and by contrast, the western region looks much cleaner.

However, a new analysis of regional air pollution levels by the Centre for Science and Environment (CSE) has shown that proximity to the sea has not helped in containing the increasing air pollution in the financial capital, Mumbai.

Even though winter pollution levels in the western region are not as high as that seen in the Indo-Gangetic Plains due to its proximity to the sea and improved ventilation, the levels have been seen to be increasing despite the geographical advantages and favourable meteorology, the CSE analysis said.

In other words, increasing air pollution is not restricted to winters but is now an yearlong problem in Mumbai too.

“The number of bad-air days in Mumbai have doubled between 2019 and 2021, while good days are down by 20 per cent. This underscores the urgency of scaling up action across all sectors to prevent further worsening and to arrest the trend in this region,” executive director, research and advocacy, CSE, Anumita Roychowdhury said.

This new analysis, released on Wednesday, of real time pollution data is part of CSE’s air quality tracker initiative and also has an assessment of annual and seasonal trends in PM2.5 concentration for the period January 1, 2019, to January 9, 2022.

This analysis is based on the real time data available from the current working air quality monitoring stations. Review of data availability from the automated monitoring stations in the region under the continuous ambient air quality monitoring stations (CAAQMS) programme of Central Pollution Control Board (CPCB) shows major data gaps. When it comes to data availability calculated as number of days with adequate PM2.5 data for computation of a valid 24-hour average, among Mumbai stations, Kurla in east-central Mumbai had only 55 per cent data while Malady (West) in north Mumbai came up with 68 per cent.

“It is not clear why these stations have such poor data availability despite minimal problems of electricity and internet connectivity in the region,” said CSE’s programme manager, Urban Data Analytics Lab, Avikal Somvanshi.

Like other cities in Maharashtra and Gujarat, studied as part of the same analysis by CSE, Mumbai too has indicated a rising trend in annual PM2.5 levels after an initial drop during 2020 (when there were lockdowns) with a rebound and a rising trend visible in 2021.

The CSE analysis to indicate that the number of bad-air quality days are increasing in Mumbai is supported with Air Quality Index (AQI) data. Daily AQI analysis based on 10 oldest stations shows a 20 per cent drop in the number of good AQI days in the city between 2019 and 2021 — while days with poor or very poor AQI have doubled.

South Mumbai has the worst air within the city during winter: In December 2021, the stations in south Mumbai reported significantly higher PM2.5 levels compared to the rest of the city.

Mazgaon with a monthly average of 134 micrograms per cubic metres was the most polluted neighborhood of the city, followed by Navy Nagar, Colaba (124 micrograms per metre cube), Kurla (101 micrograms per metre cube), Vile Parle-West (101 micrograms per metre cube) and Worli (97 micrograms per metre cube).

Khindipada, in north Mumbai, which is at the edge of Sanjay Gandhi National Park in the suburbs with a monthly average of 54 micrograms per metre cube was the least polluted neighborhood. Bandra and Malad (West) reported low numbers, but the values are not considered valid due to a significantly large amount of missing data from these two stations, the CSE analysis showed.

Meanwhile, Maharashtra Health Minister Rajesh Tope said the Centre should think about enforcing mandatory Covid-19 vaccination to tide over hesitancy among a segment of people.

The state has reported 238 new cases of the omicron variant of coronavirus, raising their overall count to 1,605, a health department official said. Maharashtra’s positivity rate is 21.13 per cent, the official said.
