West Bengal Dengue Cases Double As Monsoon Raises Health Concerns
West Bengal is seeing dengue cases rise quickly during the monsoon season.
More than 5,000 cases were reported by September 11.
Murshidabad, Kolkata and North 24 Parganas have reported the most cases.
Mosquitoes that spread dengue can grow in small amounts of still water around homes.
People should empty or cover buckets, flowerpots and other containers that collect water.
Dengue can cause fever, headache, body pain, nausea, vomiting and rashes.
A person may become more seriously ill even after the fever starts to fall.
Severe stomach pain, bleeding, unusual sleepiness or fast breathing need urgent medical attention.
Doctors also advise against taking aspirin or ibuprofen unless a doctor recommends them.
West Bengal reported 5,002 dengue cases by September 11, up from fewer than 2,500 at the end of August.
Murshidabad recorded 1,072 cases, followed by Kolkata with 500 and North 24 Parganas with 450.
The state designated 29 municipalities, 85 community development blocks and 278 village panchayats as dengue hotspots.
Authorities ordered intensified surveillance, door-to-door monitoring and testing campaigns through October 15.
Doctors urged residents to remove stagnant water, avoid self-medication and seek care for persistent fever or warning signs.

How dengue should be controlled
Shared Public-Health Responsibility
State authorities and healthcare systems should lead vector control, surveillance, testing, breeding-site removal and public-awareness efforts.
Individual Household Prevention
Residents must regularly inspect and clear water from homes, terraces, balconies, gardens, drains and containers because dengue mosquitoes can breed in small amounts of stagnant water.
How illness should be managed

Health workers and doctors emphasize prompt testing, medical assessment and monitoring of warning signs, fluid status, urine output, haematocrit and blood counts.
