The rural regions of Yavatmal district witnessed 58 confirmed cases of scrub typhus between September and October 2025, claiming two lives in the Wani and Arni areas.

The bacterial infection, transmitted through the bites of infected chigger mites thriving in agricultural fields and bushy areas, has established a pattern of recurring outbreaks across Vidarbha that exposes critical gaps in disease control infrastructure and support systems available to farming communities.

Agricultural labourers and families working in cotton fields, paddy cultivation zones and forest-edge settlements bear the brunt of this preventable disease, which continues to spread despite known transmission patterns and available treatment protocols.

The surge in infections follows a familiar trajectory for Vidarbha. Between August and October 2018, the region experienced its first major recorded outbreak when 200 cases emerged across multiple districts, resulting in 35 deaths. Nagpur district alone recorded 101 cases, with Nagpur Rural reporting 60 infections during that period.

The disease had remained largely undiagnosed in the area until diagnostic facilities at Government Medical College and Hospital in Nagpur began testing samples through the Integrated Disease Surveillance Programme. Prior to 2018, only 29 samples were received for testing during the same months in 2017, with just two showing positive results.

The 2025 outbreak in Yavatmal district demonstrates how the disease persists in affecting the same vulnerable populations. September recorded 27 cases, followed by 24 new infections within the first ten days of October.

Kalamb, Arni and Yavatmal talukas reported the highest concentration of cases. District health authorities responded by distributing doxycycline tablets in high-risk zones and launching BTI insecticide spraying to control mite breeding in affected areas.

Maharashtra as a whole recorded 132 cases and five deaths by September 2025, marking the highest annual fatality count in recent years. The previous year saw 130 cases with one death, while 2023 recorded 196 cases and one death.

Impact on Farmers and Rural Health

The bacterial infection, caused by Orientia tsutsugamushi, presents symptoms resembling malaria, dengue or chikungunya.

Patients develop high fever, severe body aches, headaches and weakness. A pathognomonic sign called eschar, a cigarette butt-like blackish mark or scab at the site of the mite bite, appears in some patients.

Studies conducted in Vidarbha found eschar in only 5.3 per cent of positive patients tested during the 2018 outbreak, while research from Yavatmal's Shri Vasantrao Naik Government Medical College showed the characteristic mark in 31.03 per cent of 29 confirmed cases. The presence or absence of eschar varies significantly, complicating early diagnosis for clinicians treating fever cases in rural settings.

Agricultural workers face heightened exposure during specific seasonal windows. The disease typically surfaces between August and October, coinciding with the monsoon and post-monsoon harvest season when vegetation growth peaks and mite populations flourish. Cotton farmers in Yavatmal district, which hosts approximately 3.4 million cotton cultivators across the region, spend extended hours in fields where the larvae of trombiculid mites attach to human skin while feeding.

The chiggers, measuring merely 0.1 to 0.2 millimetres, remain virtually invisible to the naked eye. Farmers working in paddy fields, those engaged in clearing vegetation around farms, and labourers collecting firewood from forest areas equally face infection risks.

The lack of protective measures compounds exposure risks. Farmers and agricultural workers rarely use full-body protective clothing while working in fields. The cost of appropriate gear, combined with intense heat during working hours, discourages the use of long-sleeved shirts, full-length trousers and covered footwear recommended for mite bite prevention.

Insect repellents containing DEET, dimethylphthalate or benzyl benzoate remain largely unavailable or unaffordable in rural areas. Field workers often cannot afford to reduce working hours or take protective breaks, as their daily earnings depend on covering maximum acreage during peak agricultural seasons.

The economic distress pervading Vidarbha's farming communities further restricts their capacity to adopt preventive measures. Between 2001 and 2016, Yavatmal district recorded over 3,500 farmer suicides, earning the grim designation as the farmer suicide capital.

The region struggles with massive debt burdens, with 95 per cent of cotton farmers facing financial strain.

Rising cultivation costs, plummeting cotton prices, repeated crop failures, lack of irrigation facilities and dependence on erratic rainfall create an environment where health concerns take secondary priority to economic survival.

Farmers lacking basic social infrastructure, including all-weather roads, regular electricity supply and accessible primary healthcare facilities, cannot prioritise protective equipment purchases when facing choices between agricultural inputs and health precautions.

Vulnerabilities in Healthcare and Prevention

Diagnostic infrastructure gaps perpetuate the cycle of delayed treatment and complications. Before 2018, Vidarbha lacked widespread testing capabilities for scrub typhus.

Establishing diagnostic facilities at the Government Medical College and Hospital in Nagpur marked a turning point, but peripheral areas continue facing severe constraints.

Primary health centres in rural Yavatmal, Wardha, Chandrapur and Gadchiroli districts lack sufficient laboratory technicians trained in conducting rapid diagnostic tests.

The Weil-Felix test, though less sensitive than ELISA-based methods, serves as the primary diagnostic tool at peripheral health facilities. Samples requiring confirmation through IgM ELISA or PCR testing must be transported to district headquarters or tertiary care centres, causing delays of several days during which the disease can progress to severe stages.

The shortage of healthcare personnel intensifies diagnostic challenges. Vidarbha faces the worst healthcare manpower deficit in Maharashtra, with districts reporting shortfalls ranging from 25 to 60 per cent in medical officers, nursing staff and paramedics.

Nagpur experiences a 25 per cent shortfall in primary healthcare doctors and a 30 per cent deficiency in paramedics. Amravati operates health centres with 40 per cent fewer doctors than required.

Yavatmal, already strained by agrarian distress, functions with a 50 per cent shortfall in doctors at sub-district hospitals. Gadchiroli, with its predominantly tribal population, reports 60 per cent of medical officer posts remaining unfilled. These vacancy rates contrast sharply with western Maharashtra and Konkan regions, where average shortfalls remain under 20 per cent.

Healthcare workers at peripheral facilities often lack adequate training in recognising scrub typhus among acute febrile illness cases. The non-specific presentation of symptoms leads to misdiagnosis as viral fever, dengue, malaria or leptospirosis.

A study examining physician knowledge in endemic districts of Andhra Pradesh found that case detection practices remained poor, with significant gaps in awareness about changing disease epidemiology. The absence of regular training programmes for primary healthcare physicians, coupled with the limited availability of educational materials on rickettsial diseases, hampers early suspicion and empirical treatment initiation.

Treatment protocols, though straightforward and effective, face implementation barriers in rural settings. Doxycycline, administered at 100 mg twice daily for seven days in adults, produces rapid fever reduction within 36 to 48 hours when started early. Children receive 2.25 mg per kilogram of body weight twice daily for the same duration.

Azithromycin serves as an alternative for pregnant women and children. However, the policy of empirical doxycycline use for all acute undifferentiated febrile illness cases, adopted by Vidarbha district health administrators in September 2018, requires consistent drug availability at health facilities and proper adherence to treatment protocols.

The availability of doxycycline and other essential medicines fluctuates across rural health centres.

Supply chain disruptions, procurement delays and inadequate forecasting of seasonal disease patterns leave peripheral facilities understocked during outbreak periods.

Patients seeking treatment at primary health centres sometimes face drug shortages, forcing them to purchase medications from private pharmacies.

For economically stressed farming families, even the modest cost of a week-long antibiotic course can pose a financial burden. Those unable to afford complete treatment courses risk developing complications, including acute respiratory distress syndrome, meningitis, multi-organ dysfunction and death.

Recurring Risks and Uncoordinated Response

Vector control measures implemented during outbreaks reveal systemic limitations. District health teams conduct BTI insecticide spraying in affected areas to control mite breeding, but the effectiveness of these interventions remains questionable.

Research on scrub typhus vector control shows that compounds like dieldrin, applied at 2.5 pounds per acre, can reduce chigger populations by over 91 per cent for at least two years.

However, concerns about environmental impacts and wildlife hazards limit the use of long-acting organochlorine insecticides. Alternative compounds like organophosphates and carbamates require reapplication every few weeks, demanding sustained resources and coordination that overstretched district health departments struggle to maintain.

Habitat modification, recognised as a crucial component of vector control, receives minimal attention in Vidarbha's agricultural landscape. Clearing vegetation around habitation areas, managing rodent populations that serve as natural hosts for mites and maintaining good sanitation in farm areas could significantly reduce human exposure to infected chiggers. Yet farmers lacking resources for basic agricultural inputs cannot prioritise habitat modification activities.

The absence of coordinated community-level interventions, combined with fragmented agricultural extension services, leaves individual farmers to navigate disease prevention without institutional support.

Public awareness campaigns about scrub typhus remain inadequate across rural Vidarbha. The disease, unlike dengue or malaria, lacks widespread recognition among farming communities.

Many agricultural workers remain unaware that the fever and body aches they experience could result from mite bites sustained while working in fields. The absence of visible vectors, unlike mosquitoes in malaria or dengue, contributes to a low perception of risk.

Educational programmes through village health nutrition days, school sensitisation and women's group meetings occur sporadically rather than as sustained awareness-building efforts. Information about protective measures, symptom recognition and the importance of seeking prompt medical care fails to reach the majority of at-risk populations.

The seasonal predictability of scrub typhus outbreaks should enable proactive preparedness measures. Veterinary researchers studying the disease cycle predicted a second outbreak wave during the harvest season in late January following the 2018 monsoon outbreak, noting that mite larvae require three months to reach adulthood.

This predictable pattern creates opportunities for pre-positioning diagnostic kits, ensuring adequate medicine stocks, conducting pre-seasonal training for healthcare workers and launching awareness campaigns before transmission periods.

However, disease surveillance systems lack the integration and responsiveness needed to translate knowledge about seasonal patterns into effective preventive action.

The integration of scrub typhus into routine disease surveillance frameworks remains incomplete. The Integrated Disease Surveillance Programme, under which samples reached laboratories during the 2018 outbreak, functions primarily as a reporting mechanism rather than an active surveillance system, enabling early outbreak detection and rapid response.

Fever surveillance protocols at primary health centres do not consistently include scrub typhus as a differential diagnosis.

The absence of systematic vector surveillance to identify high-risk mite-infested areas prevents targeted interventions in hotspots before human cases emerge.

Research examining risk factors for scrub typhus in highly endemic settings challenges conventional assumptions about agricultural exposure.

A cohort study in rural Tamil Nadu found that agricultural activities showed only a weak association with infection in high-prevalence areas, suggesting that substantial transmission occurs within human settlements rather than exclusively in fields. Women, more often engaged in peri-domestic activities near residences, showed higher infection rates than men in highly endemic regions. These findings indicate that control strategies focused solely on protecting field workers may miss important transmission pathways occurring around homes and villages.

The convergence of agricultural distress and public health vulnerabilities creates a reinforcing cycle of disease burden in Vidarbha.

Farmers lacking economic resources to invest in protective measures continue working in high-risk environments without adequate safeguards. Those developing infections face barriers to accessing timely diagnosis and complete treatment due to healthcare infrastructure deficits. The resulting disease complications impose additional economic costs on already stressed households, further depleting their capacity to adopt preventive measures in subsequent seasons.

Breaking this cycle requires coordinated interventions addressing both the structural determinants of health vulnerability and the immediate technical aspects of disease control.

The absence of a comprehensive scrub typhus control programme leaves response efforts fragmented across districts. Unlike vector-borne diseases such as malaria and dengue that benefit from dedicated control programmes with defined strategies, scrub typhus response depends on ad-hoc measures during outbreaks.

Proposals for structured control programmes, including those developed for endemic states like Odisha, emphasise the need for systematic case detection, community-level health worker training, establishment of laboratory networks with quality assurance and integration of preventive measures into primary healthcare delivery.

Vidarbha lacks such systematic approaches despite experiencing repeated outbreaks over multiple years.

The disease burden extends beyond confirmed cases to include undiagnosed and unreported infections. Studies estimating scrub typhus incidence through serological surveillance found that nearly 10 per cent of rural populations in endemic areas experience infection annually, with most cases remaining asymptomatic or presenting as mild illness not requiring hospitalisation.

However, between 8 and 15 per cent of infections progress to fever requiring medical care, with some developing severe complications. This hidden burden suggests that the 58 confirmed cases in Yavatmal during September and October 2025 represent only a fraction of actual infections occurring in farming communities.

The recurring pattern of scrub typhus emergence in Vidarbha, from the 2018 outbreak through subsequent annual cases to the 2025 surge, demonstrates that current approaches fail to address the fundamental drivers of disease persistence.

Farmers continue working in mite-infested environments without protective equipment. Healthcare systems continue struggling with diagnostic delays and treatment access barriers.

Vector control efforts remain reactive and short-lived rather than sustained. Public awareness remains limited despite known risk factors and preventive measures.

The gap between understanding disease transmission and implementing effective prevention widens with each outbreak cycle, leaving rural families to bear the recurring threat of a preventable bacterial infection.
