NEW DELHI: A toxic smog shrouded the Indian capital on Tuesday, driving air quality in some areas into the “severe” range ahead of winter, when cold air traps pollutants and brings a spike in respiratory illnesses.

The mix of smoke, emissions, and dust is an annual problem for authorities in New Delhi, with vehicles, construction dust, and smoke from farm fires in the adjoining northern states of Punjab and Haryana among the major contributors.

“The outlook for the subsequent six days: the air quality is likely to be in the ‘very poor’ to ‘severe’ category,” said the earth sciences ministry.

The city’s overall score on an air quality index kept by India’s top pollution authorities was ‘very poor’ at 384, the ministry added, and was likely to stay there until Thursday.

An index range of 401 to 500 falls into the ‘severe’ category, implying it affects healthy people, but is more serious for those already fighting disease.

Ministry data showed farm fires have increasingly swelled the pollution over the last three days, for a share of more than 23 percent on Monday, from about 15 percent on Saturday.

About a third of the city’s 39 monitoring stations showed a ‘severe’ score of more than 400 on Tuesday, said the Central Pollution Control Board (CPCB), well short of an air quality score of zero to 50 that it rates as ‘good’.

Swiss group IQAir also rated Delhi the world’s second most polluted city on Tuesday, after Lahore in neighboring Pakistan, where authorities also took emergency measures in the wake of Sunday’s unprecedented pollution levels.

The government in the eastern province of Punjab, home to Lahore, has blamed deteriorating air quality on pollution wafting in from India, an issue it has vowed to take up with its neighbor through the foreign ministry.

KARACHI: Pakistan’s southwestern Balochistan province has detected a fresh poliovirus case in a male child, the country’s polio eradication program said on Tuesday, taking the total number of cases reported this year to 46 as Islamabad struggles to clamp down on the infection. 

The National Institute of Health’s (NIH) laboratory confirmed detecting the virus in a male child from Killa Saifullah district in Balochistan, the program said. 

“This is the second polio case from Killa Saifullah, where several environmental samples have tested positive for WPV1,” the Pakistan Polio Eradication Program said. “So far, 23 cases have been reported from Balochistan province, 12 from Sindh province, nine from KP and one each from Punjab and Islamabad.”

Pakistan and Afghanistan are the only two countries where polio remains endemic. Since late 2018, Pakistan has seen a resurgence of cases and increased spread of poliovirus, highlighting the fragility of gains achieved in the preceding years when cases dropped in 2023 to six, from 20 in 2022 and just one in 2022. Misinformation about vaccinations and attacks by militants on polio teams have been major impediments to immunization campaigns.

At least seven people, including five school students, were killed and 23 injured in a blast in southwestern Pakistan that targeted a polio vaccination team vehicle on Friday, police said. No group has claimed responsibility for the attack. Last Tuesday, a policeman was killed in an attack on a health office that manages door-to-door polio vaccination campaigns.

The attacks have coincided with Pakistan’s third nationwide polio campaign this year, launched last week with the aim to administer vaccine drops to more than 45 million children.

Pakistani Prime Minister’s Focal Person for Polio Eradication, Ayesha Raza Farooq, has said that the government is revamping its polio eradication program to make the country free of the virus by mid next year.

“WPV1 has been detected in 76 districts, indicating widespread circulation of the virus and a continued serious risk to children’s well-being from a disease that can paralyze them for life,” the polio eradication program said. 
“Multiple doses of the oral polio vaccine and completion of the routine vaccination schedule for all children under the age of five is essential to keep them protected.”
