Intermittent rainfall is one of the main reasons for the rise in dengue cases this month, say city doctors. According to the BrihanMumbai Municipal Corporation (BMC), 68 cases of dengue were reported in the first week of October alone.
On Saturday, producer-director Yash Chopra was admitted to Lilavati Hospital, Bandra, and diagnosed with dengue. For the last few months, Chopra had been shooting for 'Jab Tak Hai Jaan' with Shah Rukh Khan, Katrina Kaif and Anushka Sharma. The film is scheduled for release on November 13.
Om Shrivastav, infectious disease specialist at Jaslok Hospital, Peddar Road, said that intermittent rainfall has created ideal breeding conditions for dengue-causing mosquito.
"Owing to scanty rainfall, there is a higher chance of formation of breeding grounds for dengue causing mosquitoes," said Dr Alan Soares, general physician, Holy Spirit Hospital who is treating five to ten cases of dengue every day.
The year as a whole has also seen an unusual rise in the number of cases. While 416 dengue cases were reported last year, the number has already crossed 500 in 2012.
Doctors said that dengue is caused by the morning bites of aedes mosquito. "A patient can get infected with the virus even at workplace. It is important to ensure that there is adequate sunlight in their work cabins," said Dr Shahid Barmare, physician, Kohinoor Hospital, Kurla.
Dengue patients usually suffer from high-grade fever, low platelet count and body ache. Doctors said that a few patients are also developing jaundice, hepatitis and Acute Respiratory Distress Syndrome because of dengue.
"Dengue cases usually die out by this month. But because of the late withdrawal of the monsoon we are still getting dengue cases. If there is no rainfall in the next few days, the numbers of new dengue cases will drop," said Dr Pratit Samdani, consultant physician, Breach Candy Hospital.
