Dengue does not come from lifestyle choices or chronic conditions. It comes from a mosquito bite during the morning commute, from water stagnating in a construction site adjacent to the office, from a monsoon that arrived two weeks ago and has not let up. The employee did nothing wrong. But the hospitalization was still preventable with earlier testing, earlier treatment and a workplace ecosystem that made seeking care easy rather than difficult.
This is the story of workforce infections. Not a disease of negligence or vulnerability. A disease of exposure, timing and access to early care.
When 9% of all hospitalizations stem from preventable infections, and when employees and children account for most of those cases, we’re not looking at bad luck. We’re looking at systematic vulnerabilities that workplace health programs can address.
The infections claims story
Section titled “The infections claims story”Infections are the fourth-largest claims chapter, after injuries (10%).
Three infection types (viral fevers, respiratory infections and intestinal infections) drive 83% of this burden. This positions infections as a high-volume, high-frequency category with strong implications for sudden absences, transmission risk and predictable seasonal disruption.
Unlike chronic diseases that build gradually or planned procedures with advance notice, infections create immediate operational challenges: an employee is at work one day, hospitalized the next, potentially spreading illness to teammates before symptoms appear.
Top insights and trends
Section titled “Top insights and trends”Insight 1: Working-age employees and their children, not vulnerable elderly populations
Section titled “Insight 1: Working-age employees and their children, not vulnerable elderly populations ”When we analyzed who’s getting hospitalized for infections, the distribution was striking:
| Relationship | % of total claims | Hospitalization rate (per 1,000 lives) | Average cost per claim | Key insight |
|---|---|---|---|---|
| Child | 20.70% | 5.63 (highest risk) | ₹27,782 | Children are hospitalised most frequently, often due to infections and acute symptoms that escalate quickly |
| Employee (self) | 45.70% | 3.62 | ₹42,901 | Employees account for the largest share of claims, reflecting direct impact on workforce productivity |
| Spouse | 14.40% | 3.36 | ₹40,535 | Spouse claims are moderate in both frequency and cost, driven largely by maternity and general illnesses |
| Parents | 16.10% | 3.06 | ₹68,435 (costliest) | Parents have the highest cost per claim, driven by chronic conditions, surgeries and age-related complications |
Adults in their prime working years should have stronger immune systems than elderly populations, yet they’re getting hospitalized for infections at rates far exceeding older dependents.
This points to exposure patterns: daily commutes through crowded public transport, eating at street vendors or shared canteens, inadequate access to clean drinking water during work hours and poor hygiene facilities in public spaces.
Children amplify this pattern through school and daycare transmission chains. At 20.70% of infection claims, children are a larger share here than in any other chapter except general symptoms. The child infection burden drives parental disruption: emergency leave, hospital visits and caregiving stress.
Parents represent only 16.10% of infection claims, remarkably low given they dominate kidney (63.7%), cataract (26%) and heart disease claims. Infections are overwhelmingly a young-population problem.
Insight 2: Two infection types dominate
Section titled “Insight 2: Two infection types dominate”There is no mystery about what is driving hospital infections in the Indian workforce. Two ailment categories account for 83.3% of all claims in this chapter. Everything else (tuberculosis, hepatitis, fungal infections, parasitic diseases) combined makes up the remaining 17%.
| Infection type | % of chapter | Average cost per claim |
|---|---|---|
| Arthropod-borne viral fevers (dengue, chikungunya) | 46.4% (largest) | ₹35,841 |
| Intestinal infectious diseases (typhoid, dysentery, food-borne) | 36.90% | ₹33,615 |
| Viral hepatitis | 3.60% | ₹38,984 |
| Other viral diseases | 3.60% | ₹31,555 |
| Other bacterial diseases (septicaemia, leptospirosis) | 3.00% | ₹94,915 (costliest bacterial) |
| Protozoal diseases (malaria) | 2.20% | ₹41,645 |
| Tuberculosis | 1.20% | ₹1,08,996 (costliest overall) |
| All others (7 categories) | 3.10% | n/a |
The two leading diseases are largely preventable through vaccination, hygiene protocols, safe food and water access and early treatment. Their persistence as major hospitalization drivers signals that preventive interventions aren’t reaching the workforce effectively. These are largely treatable conditions when addressed early.
Insight 3: The dengue and chikungunya story, 46.4% of all infection claims
Section titled “Insight 3: The dengue and chikungunya story, 46.4% of all infection claims”Dengue and chikungunya together represent nearly half of all infection hospitalizations. These are mosquito-borne diseases that spike sharply during and after the monsoon, when stagnant water around residential areas and construction zones accelerates mosquito breeding.
Employees commuting through urban environments, living near water bodies, or working outdoors are at elevated exposure. A dengue admission typically runs five to seven days, platelet monitoring requires daily pathology and in severe cases, it progresses to ICU admission.
The intestinal infection story, 36.9% of all infection claims
Section titled “The intestinal infection story, 36.9% of all infection claims”Typhoid, dysentery, acute gastroenteritis and food-borne illness are the conditions behind intestinal infection claims.
These are water and food safety failures: contaminated drinking water at field sites, street food consumed during long commutes, canteen hygiene lapses and contamination of monsoon-season water supplies. Intestinal infection incidence rose from 0.75 per 1,000 in 2023 to a peak of 1.62 in 2025. It has not recovered to anything near its baseline.
The hidden concern: tuberculosis growing quietly
Section titled “The hidden concern: tuberculosis growing quietly”Tuberculosis (TB) accounts for only 1.2% of infection claims by volume, but at ₹1,08,996 per claim it is the costliest infection in the dataset, and it is growing.
TB predominantly affects the 21 to 30 age band and enrolled parents, meaning both the core productive workforce and older dependents are being diagnosed. TB requires prolonged treatment, long-term absence management and contact tracing. Its quiet escalation in this data warrants active screening, particularly in high-risk geographies.
Other bacterial diseases, which include severe systemic infections like septicaemia and leptospirosis, cost ₹94,915 per claim on average. At 3% of infection volume, this category has an outsized financial footprint. These are infections that arrive late, escalate fast and are expensive to manage. Earlier diagnostic access would reduce both their frequency and their cost.
Insight 4: Seasonal infection spikes create predictable quarterly disruption
Section titled “Insight 4: Seasonal infection spikes create predictable quarterly disruption”Overall infection seasonality shows extreme concentration in the monsoon season. Nearly 67% of all infection claims fall in Q2 and Q3 combined. The seasonality is stark and predictable.

| Category | Share of infection claims |
|---|---|
| Q1 (Apr–Jun) | 17% |
| Q2 (Jul–Sep) | 35% |
| Q3 (Oct–Dec) | 32% |
| Q4 (Jan–Mar) | 16% |
Viral fevers surge during the monsoon when mosquito breeding accelerates. Intestinal infections spike when water contamination and food spoilage risks increase. These are not surprises; they are foreseeable disruptions that can be planned around.
Why this matters for workplaces
Section titled “Why this matters for workplaces”Infection-related hospitalizations may not dominate cost, but they dominate disruption:
- Sudden sick leave
- Child-care emergencies for working parents
- Short but intense productivity loss
- Spillover transmission within teams
Because infections affect younger populations, they directly impact the most economically active segments of the workforce.
What HRs can do
Section titled “What HRs can do”Infections in workforce claims are less about pathogen virulence and more about timing, immunity and access to care. Organizations that invest in prevention and early intervention see material reductions in infection-related hospitalizations.
A. Preventive actions
Section titled “A. Preventive actions”Build immunity through comprehensive vaccination programs:
- Annual flu vaccines for all employees, especially before peak seasons
- Typhoid vaccination for employees in areas with unsafe water or food risks
- Hepatitis A vaccination, especially relevant given high intestinal infection rates
- Pneumococcal vaccines for employees with chronic conditions or compromised immunity
- Pediatric vaccination tracking for dependents (rotavirus, hepatitis A, flu): reducing the child infection burden prevents parental disruption
Address immunity gaps identified in health screenings:
- Iron supplementation for employees with anemia improves infection resistance
- Vitamin D correction for deficient employees directly supports immune function
- Diabetes management programs: better glucose control reduces infection risk and severity
- Nutrition counseling focused on immune-supporting foods (zinc, vitamin C, protein)
Strengthen workplace hygiene infrastructure:
- Ensure clean drinking water access throughout work premises and during field assignments
- Hand hygiene stations with soap and sanitizer at multiple locations
- Food safety protocols for workplace canteens: regular inspections, handler hygiene, proper storage
- Enhanced sanitation during peak infection seasons (Q2 and Q3, the monsoon months)
- Mosquito control measures around premises during monsoon to reduce dengue exposure
B. Policy and coverage
Section titled “B. Policy and coverage”- Comprehensive OPD packages for employees, so they can go to the doctor if they have fever, diarrhea, or respiratory symptoms
- 24/7 tele-consultation for initial symptom assessment and triage guidance
- Diagnostic testing for dengue NS1, typhoid, malaria and stool cultures
- Dependent coverage for pediatric infections: reducing the child infection burden prevents parental work disruption
- Pre-monsoon awareness campaigns or wellness sessions about dengue, leptospirosis and foodborne illness prevention
