Sri Lanka surge: Approximately 35,000 dengue cases reported; hospitals described as under strain. Post-Diwali season risks were highlighted in commentary. Media reports were the dominant source.

Delhi pre-monsoon operations: The MCD intensified larvae surveillance and source reduction activities, including water accumulation checks on rooftops and government offices, and oil/insecticide spraying in areas such as Green Park. Special drives were extended to government premises. Both dengue and malaria larvae were targeted. Operationally and officially driven.

Kerala alert: A dengue alert was issued for the Kochi/Thripunithura municipality. Individual and community responsibility for source reduction was emphasised alongside official messaging.

National dengue vaccine discussion: This generated the most policy debate of the week.

• Brazil scaling one-shot Butantan dengue vaccine rollout attracted comparative attention.
• India: Qdenga (Takeda TAK-003) approval was characterised as a “landmark” development; commercial launch described as imminent but affordability concerns raised prominently.
• Calls for urgent rollout cited India’s estimated case burden (20–40 million cases per year in some commentary, though this figure varies considerably by source).
• Key caveats included: vaccine alone insufficient; needs sustained pharmacovigilance, phased rollout, and integration with vector control. Comparisons to Dengvaxia safety concerns in seronegative individuals were raised.
• Interest in affordable Indian-manufactured tetravalent options noted; potential Russia-India co-production mentioned in passing.

• Nipah differential outbreak risks (India): A new report in Nature (covered by the Indian Express) explored why Kerala and West Bengal experience different outbreak patterns despite sharing the same virus. Ecological factors and differential health system strength were highlighted. ICMR-Delhi was referenced. Expert and analytical in character; not acute outbreak reporting.
• Bangladesh – Nipah survivorship: Long-term functional, cognitive, psychosocial, and economic hardship extending well beyond the acute phase was highlighted from a newly published study. Low engagement, but scientifically substantive.
• Karnataka (Kodagu/Kushalnagar) – post-Bakrid sanitation: Overflows of animal blood into drains, associated foul odours, and vermin proliferation raised local concerns about animal-to-human disease transmission risk. Shared as an operational observation with video. Low engagement, but a relevant One Health weak signal.

• Digital tools and community engagement: MoHFW actively promoted the #TBMuktBharat App, a digital platform linking Ni-kshay Mitra, volunteers, district administration, and patients, with an emphasis on transparency and streamlined access to care.
• Nikshay Poshan nutrition support: Ongoing district-level distributions were reported (Indian Red Cross Society in Ajmer, Rajasthan; Gujarat State TB Cell health bulletins). Part of routine TBMuktBharat implementation.
• Vaccine advocacy: Articles highlighting the urgent need for an effective TB vaccine cited the PreVenTB trial as a hopeful signal. Tagged to ICMR-Delhi and MoHFW. Low frequency but substantive.

Karnataka AMR Surveillance (lead story): TIGS-India, in collaboration with the Karnataka Department of Health and Family Welfare, launched a statewide AMR Surveillance Programme to track resistance trends, strengthen preparedness, and support evidence-based action. Reported in The Hindu. This is a concrete and significant operational development.

Global and technical posts with India relevance:

• NDM carbapenem-resistant infections: US surveillance data showing a sharp rise in NDM-producing organisms was discussed, with implicit relevance to India given the epidemiological linkage.
• OXA-1054 carbapenemase: New characterisation in Pseudomonas aeruginosa was noted in technical posts.
• Candida auris education: Posts covering its emergence as a multi-drug-resistant nosocomial yeast, high mortality, and hospital environmental persistence were circulating. No India-specific outbreak reports were captured.
• Colistin MIC and outcomes: Post-hoc data from the OVERCOME trial examining the impact of colistin MIC on outcomes in carbapenem-resistant Gram-negative bacteraemia/pneumonia was shared.
• India-specific call to action: An explicit comment calling for routine AMR susceptibility testing in Indian critical care settings prior to antibiotic initiation (as standard in many Western hospitals) was visible. Low engagement but clinically pertinent.

Hospital IPC (operational): A medical college hospital (MLNMC Prayagraj/SRN Hospital) shared a comprehensive modular kitchen hygiene exercise including deep cleaning, rodent-entry sealing, and chimney repairs for patient food safety.

• ICMR-NIHR Jodhpur: Hosted a hands-on workshop in Exploratory Data Analysis and Statistical Modelling with R, aimed at researchers, faculty, and students.
• ICMR-National Institute of Nutrition: Participation in World Food Safety Day discussions covering unsafe food hazards and safety measures.
• Academic programmes: Delhi University ACBR summer undergraduate research activities tagged to ICMR-Delhi.
• MoHFW activities: Heatwave precautions, World Environment Day (tree plantation at NEIGRIHMS Shillong), anti-vaping messaging, and TB digital app promotion. No acute microbiology or ID outbreak alerts issued from MoHFW in this monitoring window.
• Health system pressures (peripheral): Commentary noted challenges in deploying specialised staff and equipment at taluk/general hospital level, with most complex cases referred to medical colleges (contextual to one state).

• Ebola vigilance: Intensified screening at Indian airports and seaports in response to Bundibugyo strain activity in Central Africa (Congo/Ethiopia context). Lucknow hospital isolation bed preparations reported. Samples directed to specialised laboratories (Pune referenced in one report). Emphasis on rapid diagnostics and coordinated action. Preparedness-focused; not India-endemic.
• Fever and rash surveillance: Field investigations and house-to-house activities reported in Assam (Kokrajhar district). Routine operational surveillance.

This was a relatively quiet week for acute crisis-driven or high-technical-depth microbiology/ID/AMR discussions on public X in India and South Asia. Activity was skewed towards routine operational prevention, programme implementation, state-level surveillance building, and analytical or policy commentary.
