Changing weather patterns and heavy rainfall are contributing to a rise in fever cases in the city. Infections such as leptospirosis and dengue are also being reported in the district.
A total of 9,848 fever cases were reported in the month up to November 18, according to Health department statistics. Of these, 9,516 were outpatient (OP) cases, with the remainder being inpatient (IP) cases. District health authorities have confirmed 89 dengue infections.
One of the major reasons for the persistently high number of fever cases is the inclement weather. “During the rainy season, respiratory illnesses and viral fevers circulate more for several reasons. People crowd indoors, and these confined spaces make it easier for respiratory viruses to spread. Viruses also remain viable in the air for longer when humidity rises, as happens during the rainy season,” said Dr. Rajeev Jayadevan, convenor, Research Cell, Kerala State Indian Medical Association.
“Fever is commonly caused by various respiratory viruses. Among them, the influenza virus can lead to severe symptoms, which in rare cases may be fatal, but serious outcomes can be prevented through vaccination. Older adults, in particular, should consider getting vaccinated against influenza,” he added.
He added that, besides hand-washing to remove viruses from the fingertips, an effective way to prevent the spread of illness is to take leave from work or school when running a fever. “Students should not be sent to school if they have a fever. This simple precaution can help limit further spread in the community,” he said.
In October, as many as 16,169 fever cases were recorded in the district, including 15,636 OP cases and the rest IP cases. The district also reported the highest number of dengue cases in the State that month, with two deaths being recorded. This marked a spike compared to September, when the district had registered a total of 533 suspected and confirmed cases, including 138 confirmed dengue infections and 395 suspected cases.
