Typhoid Leads India’s Confirmed Monsoon Fever Test Positivity
PharmEasy studied fever test results from 209 Indian cities during the monsoon.
Typhoid had the highest share of positive tests, with about one in four tests positive.
Dengue had fewer positive tests, followed by chikungunya and malaria.
Typhoid can spread through unsafe food and contaminated water, not just mosquitoes.
This means clean drinking water, safe food and good sanitation are important during rainy weather.
Seven of the 10 high-risk cities were mainly affected by typhoid signals.
Gwalior and Amritsar had the strongest typhoid laboratory signals in the data.
Overall fever risk increased as rainfall and weather conditions changed.
The company said its data shows risk patterns, not a diagnosis or a count of individual cases.
PharmEasy data through August 12, 2026, showed typhoid test positivity at 25.5%, compared with dengue at 8.5%.
Chikungunya and malaria recorded lower positivity rates of 1.8% and 1.4%, respectively.
Typhoid was linked to seven of the 10 cities classified as high risk by Fever Watch.
Gwalior and Amritsar recorded the highest typhoid laboratory signal, scoring 100.
National fever risk rose from 47 at the start of the season to 61 by August 12, alongside increased rainfall and weather-related risk signals.
