Sonbhadra, Uttar Pradesh: “Jab machhar sab khoon pi lela, jab beemari ho jala, tab dawai chidki ka baa? [What is the use of spraying insecticide after the mosquitoes are done feeding on our blood and giving us the disease?],” eighteen-year-old Seeta Devi’s voice cuts through the heat, as she talks from the doorway of her hut on a baking-hot day in April. Her mother-in-law Gulabi Devi (60) and sister-in-law Sonu Devi (34) are battling high fever, chills and severe body aches that have lasted for over a fortnight.
Seeta Devi’s village Sendur is 64 km away from Robertsganj, the headquarters of Sonbhadra district in south-eastern Uttar Pradesh. There is no public transport connecting these hamlets, often forcing the residents to walk anywhere between 6-12 km to reach the main road where the bus service runs. The term ‘jada-wala-bukhar’ — fever with chills — is the common reference to malaria in this isolated hamlet and associated with the rains, but malaria is no more a monsoon disease.
“After the unexpected rains in February and March, there are clouds of mosquitoes everywhere and we are getting bitten. People have begun to fall sick,” said a visibly wan Sonu Devi. “I’m barely able to fetch water or handle my household chores, leave alone weeding the fields.”
In 2018 and 2019, Uttar Pradesh, India’s most populous state, had a fifth of all malaria cases in the country, followed by Chhattisgarh (18.3%). This reporter filed a right-to-information (RTI) request with the National Vector-Borne Diseases Control Programme, under the National Centre for Vector Borne Diseases Control (NCVBDC) for district-wise malaria testing, caseloads and fatalities on April 24, 2024. In 2020, Odisha (41,739), Chhattisgarh (36,667) and Uttar Pradesh (28,668) had the most cases in the country, the NCVBDC revealed in a response dated May 17. Over the next two years, fewer cases were registered in Uttar Pradesh — 10,792 in 2021 and 7,039 in 2022. Testing rates fluctuated — from 2.01% in 2017 to 2.32% in 2018 to 1.8% in 2021, before recovering to 4.5% in 2023.
A potentially life-threatening disease, malaria is caused by microscopic parasites grouped under the Plasmodium genus. The parasites inhabit the gut and salivary glands of female Anopheles mosquitoes. Humans develop malaria after 10 to 14 days of being bitten by an infected mosquito. According to the NCVBDC, most cases of malaria in India are caused by Plasmodium vivax and Plasmodium falciparum, the latter infection being more serious and more likely to be fatal. Anopheles mosquitoes breed in stagnant water such as in pools and puddles.
Sonbadhra is full of them. Between the rocks and the forests, the terrain is pockmarked by innumerable pits filled with rainwater that stagnate for months, providing rich breeding sites for Anopheles. “Pani hai to machhar hai [If there is water, there will be mosquitoes],” said Shubham Singh, district vector-borne disease consultant, Sonbhadra.
“Each block here has 50 to 60 small and big dams, with pits and creeks alongside,” he said pointing at the wall-sized district map put up in the District Malaria Unit. The RTI response by the NCVBDC revealed that in 2019, Sonbhadra recorded 3,689 malaria cases, the third highest after Bareilly at 46,717 and Badaun at 20,339. In the non-monsoon months between January and April 2019, Sonbhadra recorded 593 malaria cases — 16% of its annual malaria caseload, the highest among Uttar Pradesh’s districts. In these four months, Bareilly trailed with 560 cases and Badaun with 307. In 2021, these months accounted for 10% of its 1,978 cases, while 33% were recorded during November-December. More recently, the district saw 57% of its cases in 2022 during January-April. The District Malaria Unit has placed 196 villages out of 1,440 in Sonbhadra on red alert for malaria.

In Makra village of Myorpur block, 52-year-old farmer Kamalbhan (he uses one name) said he burns neem leaves to repel mosquitoes. A pile of half-burnt neem leaves is heaped in a corner of his home, with a sackful nearby, kept ready for the evening.
“If they had done the chidkaav [spraying insecticide], the mosquito nuisance would have lessened. I am worried about the health of my grandchildren,” Kamalbhan gestured at the children playing in his courtyard. The National Health Mission had supplied him with two Long-Lasting Insecticidal Nets — one in 2023 and the other earlier — under the NCVBDC’s malaria elimination programme. They had proved invaluable for a good night’s sleep. “But the mosquitoes bite us day and night and we can’t use them throughout the day, right?” he grinned.
At a bus stop in the village, Ramji (he uses one name) waits for his wife’s arrival under the scorching sun. The 50-year-old boatman is running a fever and wipes his face with his gamcha as he looks hopefully at each bus that comes to the stop. His wife Brihaspatiya Devi has been seeking out various healers for their 13-year-old son Suninder who is sick with malaria. It’s the sixth day Brihaspatiya Devi has skipped work as a daily wage construction labourer to take him to a doctor.
For the first three days of his fever, Suninder was given home care, where his mother simply swaddled him in blankets and hoped the fever would subside. When the boy’s health worsened, she walked him 6 km to a local jholachap or unlicensed medical practitioner. The nearest sub-centre/primary health centre is 4 km away, and takes 20 minutes by walk but the mother was unsure of finding a doctor there. She had borrowed Rs 180 to pay for Suninder’s treatment but, “the medicines didn’t work”, said a distraught Brihaspatiya Devi.
Two days later, they had again walked several kilometres to a main road, where she was able to catch a bus to see an allopathic doctor at a private clinic. A blood test was done and malaria was confirmed three days later. Suninder was given antimalarial drugs for 14 days and recovered. In all, the family had to spend Rs 3,000 on the diagnosis and medicines. Brihaspatiya Devi said she was thankful that her elder son Satinder (18) had migrated to Chennai for work. “At least he will escape these repeated threats of malaria,” she said.
“We lose sleep having to wave away mosquitoes,” added Ramji. Behind Ramji’s house is an unused well replenished with water all through the year, thanks to the erratic rainfall patterns.
New transmission windows emerge
While malaria is showing up unannounced, the district health department awaits guidelines for using a new compound for Indoor Residual Spraying (IRS) from the Department of Family and Health Welfare. IRS is recommended by the NCVBDC as a mosquito control measure and involves coating walls and other surfaces with an insecticide. DDT or dichloro-diphenyl-trichloroethane, which was the compound of choice for the purpose for decades, was phased out last December.
In May, as heatwave alerts were sounded in the district, Dharmendra Srivastava was at a malaria medical camp in Makra. The District Malaria Officer had been happy to note that bed nets were widely used, but added that, “till last year, DDT spraying was carried out twice a year, between May 15-June 30 and then again between September 15-October 15. For this year, we haven’t yet received any guidelines about the new insecticide.”

IRS is carried out during the peak months for malaria — that is, the post-monsoon months of September-October. Ideal ecological conditions are created for the mosquitoes to breed post rainfall and IRS can make the breeding sites inhospitable. But these timelines are now old, and “need to be revisited based on the extension of the malaria transmission window and must be planned at a localised level”, observed Ramesh Dhiman, former scientist at the National Institute of Malaria Research, who is currently the national coordinator for the Global Fund for Malaria, an international financing and partnership organisation to end the epidemics of HIV/AIDS, tuberculosis and malaria.
In two decades to 2019, Sonbhadra has seen declining rainfall. The following four years saw instances of erratic rainfall: 2020 and 2021 saw large amounts of rainfall pre-monsoon, while the monsoon was normal or near-normal; 2022 and 2023saw deficit monsoons. Farmers have been put to distress by the erratic rainfall and intermittent periods of drought. In recent years, a prolonged transmission window for malaria has also emerged in Sonbhadra. The monthly data obtained from the District Malaria Unit showed that in 2019, malaria caseloads peaked in September. In 2020, the peak season extended to October and then to December in 2021 and 2022.
This year, Sonbhadra received excess rainfall in February. The average mean temperatures hovered between 20-22°C. In March too, the district received excess precipitation, with a mean temperature between 24-26°C. Most Anopheles mosquitoes develop in the optimal temperature range within 20-30°C, making both months favourable for breeding.
“The caseload is high even in months which weren’t considered as malaria transmission window earlier. Rising heat and changing rainfall patterns directly impacts the malaria transmission trends,” said Rajib Chattopadhyay, scientist at the India Meteorological Department, Pune who is also heading the Climate Application and User Interface team to look at the correlation of climate and health. The behaviour of the malaria vector is changing with a changing climate.
“Some places in high altitude regions where malaria was unheard of are facing the disease now. These can be directly attributed to climate change. In such a scenario, Uttar Pradesh can easily transform from a low-risk area into a high-risk area,” he added. In Amroha district in north-west Uttar Pradesh, for instance, there was a malaria outbreak in January, observed Vikasendu Agarwal, state surveillance officer under the Integrated Disease Surveillance Programme.
Need for a holistic approach
According to the World Malaria Report 2023, there were an estimated 249 million malaria cases in 85 malaria-endemic countries and areas in 2022, an increase of 5 million cases compared with 2021. India accounted for 1.4% of the global caseload and for two in three cases in the WHO’s South-East Asia region. However, India also recorded the highest decline in cases (30%) during 2021-22 among 11 high-burden countries. Malaria deaths also fell 34%.
These gains may be short-lived: The report noted that climate change has the potential to trigger reintroduction of malaria in areas that have high receptivity and in which malaria has recently been eliminated.
The decline in India’s caseload has been evident since 2015, after the country launched a National Framework for Malaria Elimination Programme in 2016. The strategy is to eliminate the disease in a phased manner by 2030 and prevent its resurgence in areas where malaria transmission has been interrupted. However, a review of malaria elimination in 2022 warned that the effect of climate change on malaria is a crucial epidemiological aspect that cannot be ignored any longer.
The review makes a series of recommendations including two that can help tackle malaria holistically, deploying a One Health approach: carry out climate change studies to understand the resurgence of malaria in areas where it has been well-controlled or eliminated, and include multisectoral as well as cross-border collaboration as a standard agenda item in the monthly meetings of state, district and block-level task forces.
One Health is a collaborative, multisectoral, and transdisciplinary approach, working at the local, regional, national, and global levels. The goal is to achieve optimal health outcomes recognising the interconnection between people, animals, plants, and their shared environment. Although malaria is not specifically included in India’s national programmes for One Health, a One Health-informed multisectoral and cross-collaborative approach is discussed in the country’s malaria elimination programme.
The review acknowledged that the collaboration efforts between the health and non-health sectors, such as water resources, panchayati raj and rural development, and agriculture were “mostly episodic” and that this was a gap in malaria elimination efforts.

For example, Sonbhadra has the long-standing problem of poor groundwater reserves. A 2012 report by the Central Ground Water Board had recommended groundwater recharge structures like check dams to counter this problem, “which are now active breeding sites for Anopheles,” said the district malaria officer. The erratic rainfall throughout the year is making these breeding sites perennial — like the unused well outside Ramji’s house which has standing water year-round, and the creeks surrounding Gulabi Devi’s house, adjacent to Rihand dam, which are water-logged everytime it rains.
Intense entomological studies are also the need of the hour, according to Atul Kumar, India Program Head—Health in the NGO Prayatna. Kumar has 13 years of experience working on malaria, and noted that Anopheles mosquitoes have altered their biting patterns. “Unless we study the vector behaviour, how will we develop a message for the community?” he questioned.
But Sonbhadra has no appointed insect collector or district-level entomologist to conduct such studies. The state entomologist Vipin Kumar could not detail any specific studies conducted in this regard. Dhiman calls this a case of negligence.
More than a health crisis
The malaria patients in Sonbhadra’s villages are dependent on paracetamol and painkillers, procured from quacks. Gulabi Devi prefers the quack because “the hospital is too far and Rs 150 required to reach there is too much”. Brihaspatiya Devi took Suninder to a quack because she can pay him as and when she has money. Sonu Devi didn’t go to the nearest primary healthcare centre in Kunwari because the doctors may not be available.
The jholachaps or unlicensed medical practitioners here have the trust of the community. ‘Jhola’ refers to the bag of remedies which the healer carries, which villagers view as a sufficient stamp of authority ‘chaap’ to heal the sick.
Poor awareness about effective malaria treatment amongst locals challenges the healthcare system too. The health department finds it difficult to convince them for testing and complete the medication course. The district malaria officer Srivastava cites an example: “Once we came across a woman who needed immediate medical attention for malaria but her husband told us that he would rather get a new wife in the amount he needs to spend treating his current wife.”
Brihaspatiya Devi and her husband Ramji are marginal workers who make Rs 250 per day working on construction sites. Collectively they lost Rs 1,250 since their son fell ill with malaria. The family had spent Rs 3,000 for injections, tablets and transportation. It had taken Brihaspatiya Devi over a year to save that money.
Gulabi Devi in Sendur relates to these circumstances. Her family depends on a small general store for a hand-to-mouth income. The malaria expenses have put them in an economic spiral.
“But how do I weigh the value of Rs 1,100 with my life,” she questioned.
