1,775 dengue cases in a month: Chennai's civic machinery fails its own people

CHENNAI: The Greater Chennai Corporation has taken its mosquito war to the skies. On Wednesday, drones swept over the Cooum river and the Buckingham Canal, spraying larvicide over the stagnant water below. It made for impressive footage. It was also an admission of failure. The city recorded 1,775 confirmed dengue cases in September alone, a number large enough to force the civic body to escalate its vector-control operation and intensify the hunt for mosquito breeding sources across the city. Dengue is not a mystery disease. It is monsoon arithmetic. The Aedes aegypti mosquito breeds in stagnant water: in open drains, in waterlogged lanes, in construction pits, in the discarded vessels and clogged culverts that every Chennai neighbourhood knows by name. When the drains do not flow and the garbage is not cleared, September writes its own case count. The Cooum and the Buckingham Canal are the city's oldest shame. Successive governments have announced grand cleaning drives, allocated crores and cut ribbons; the waterways remain open sewers and the most reliable mosquito nurseries in Tamil Nadu. That the corporation must now spray larvicide from the air over the same canal it has promised to clean for decades is the story in a single frame. This is also the first monsoon test of the TVK government's civic machinery. The administration inherited the drains, but it owns the response now. A drone fleet is a showcase; covered drains, cleared garbage and a year-round vector-control programme are a system. Tamil Nadu's public-health experts have warned for years that fogging and spraying campaigns conducted only after case counts spike are theatre. Breeding control has to run through the dry months, in the localities, with sanitation workers who are paid and staffed. The arithmetic of dengue is also the arithmetic of class. The cases do not cluster in gated communities. They cluster where water stagnates longest: in waterlogged slums, in tenements abutting open drains, in households that cannot afford private hospitals. The daily-wage worker who misses a week of work to dengue fever loses more than health; he loses the month's budget. Government hospitals absorb the surge every year, and every year the surge arrives on schedule. The corporation's drones will fly again, and the footage will air. The real test of the TVK government's first monsoon is simpler and harder: whether the drains flow, the garbage moves and the breeding sites are cleared in the next sixty days, before the next spike, not after it. If the count explodes again, it will not be an accident. It will be a choice.
