Pune PMC Launches Two-Month Night Blood Survey to Detect Elephantiasis Among Migrant Workers
The Pune Municipal Corporation (PMC) has launched a two-month night blood survey to detect lymphatic filariasis, commonly known as elephantiasis, among construction workers and migrant labourers in the city.
The campaign began on October 14, 2026, with blood samples being collected between 9 pm and midnight. The survey focuses on construction sites and other locations where workers stay overnight, as the parasites responsible for the disease are detectable in human blood at night.
Pune is not considered an endemic area for filariasis and currently has seven old cases, according to PMC’s information. However, migrant workers arriving from states where the disease is more prevalent have prompted the PMC to identify infected individuals early and prevent local transmission.
A 12-member team is conducting the campaign, comprising six PMC employees and six staff members from the state health department. The civic body has directed vector-borne disease prevention inspectors at ward offices to remain present at survey locations. Six ward office employees have also been assigned to assist the state health team with sample collection.
Filariasis is a parasitic disease transmitted through the bite of an infected female Culex mosquito. The infection can remain without symptoms for months or years. If left untreated, it can cause severe swelling of the limbs, genital complications and permanent disability.
The campaign aims to identify infected individuals and ensure timely treatment to prevent the disease from spreading within Pune.
