Health experts warned Monday that the national capital has seen a surge in dengue, flu, and throat infections due to the unrelenting rains.

Experts claim that these conditions are exacerbated by high humidity, temperature swings, and waterlogging in many places.

Because of their high rate of transmission, seasonal illnesses like dengue and influenza are becoming more prevalent this season. The majority of instances resolve on their own without the need for hospitalization or active medication, according to Dr. Harshal R. Salve, an additional professor at AIIMS’ Centre for Community Medicine in New Delhi.

“The number of dengue cases has increased during the last few weeks. Fever, joint problems, body aches, rashes, and occasionally bleeding from either side are among the frequent symptoms that patients experience, said Dr. Rishikesh Desai, an expert in internal medicine from a prestigious city hospital.

The vector-borne infections, which include chikungunya and malaria, are brought on by mosquitoes growing in stagnant water.

In 2025, there have been 499 occurrences of dengue, 235 cases of malaria, and 37 cases of chikungunya, according to the most recent weekly data from the Municipal Corporation of Delhi. This is more than the 29 occurrences of chikungunya, 210 cases of malaria, and 481 cases of dengue that were reported during the same time period in 2024.

Delhi has seen a lot of rain in recent weeks, which has caused waterlogging. In addition to the extreme humidity, the temperature varies significantly. According to Desai, all of these characteristics have the potential to impact health and result in vector-borne, water-borne, and respiratory or airborne illnesses.

“Throat infections are also being caused by the rise in humidity,” he said. In addition to fever, the patients are complaining of throat pain, congestion, or running noses.

According to the doctors, additional typical symptoms during this time include fever, vomiting, loose movements, abdominal pain, and dehydration.

“Cough hygiene, handwashing, controlling hydration, and preventing transmission by donning a surgical mask are all preventive measures for the flu.” See your physician if any of these conditions exist. Salve advised against taking any antibiotics without a prescription.

In order to prevent mosquitoes from breeding, the expert also suggested keeping the area clean and avoiding letting water stand still. Wearing full-sleeved clothing and applying insect repellents during the day can also be beneficial.
