Dengue and Flu Cases Surge Amidst Monsoon Season in Chennai

As the Northeast monsoon brings heavy rains to Chennai, health concerns are rising due to a sustained increase in dengue and influenza cases. Local doctors are emphasizing the importance of preventive measures to combat these infections during this rainy season.

Current Situation of Dengue and Influenza

Dr. Suresh Kumar, a senior consultant in infectious diseases at Apollo Hospitals, highlights a concerning trend in patient overlap between dengue and influenza, noting that 15% to 25% of his patients exhibit symptoms of both illnesses. This dual presence extends the duration of fever to approximately 10 to 12 days.

Some patients are showing atypical symptoms attributed to dengue, such as elevated liver enzymes and neurological issues, which can lead to confusion and altered mental status. Fortunately, Dr. Kumar reports that recovery rates remain high, with most patients responding well to treatment.

Rising Fever Cases and Potential Risks

Doctors are observing spikes in fever-related cases with low platelet counts, a condition known as thrombocytopenia, particularly over the past month. Although the mortality rate remains low, the combination of tropical infections complicates diagnosis and treatment.

Dr. Sowmya Sridharan, a consultant in infectious diseases at Kauvery Hospital, noted a mild decrease in flu cases since mid-October, yet dengue cases continue to be significant. Severe symptoms have been reported, necessitating hospital admissions for some patients who arrive late in their illness—typically around day four or five, often presenting dehydration and organ dysfunction.

Guidance for Managing Fever

Medical professionals advise parents on how to manage fever symptoms in children. According to a government doctor, if a child remains active, eating normally, and does not exhibit vomiting or severe headaches, it is generally safe to use paracetamol as prescribed and monitor the situation at home. However, if warning signs arise—such as lethargy, vomiting, abdominal pain, and decreased urine output—prompt medical attention is advised.

Doctors stress that communication is key; parental anxiety can be alleviated through proper guidance from healthcare providers regarding when to seek further help.

Preventive Measures to Take

In light of increasing infections, it is crucial to adopt preventive strategies. Dr. Sridharan warns of the risk of gastroenteritis and bacterial infections like typhoid, which may be exacerbated by water contamination during the rains. Therefore, it is advisable to avoid consuming food from potentially unsafe sources during this time.

To mitigate dengue risk, residents should ensure that there is no waterlogging in and around their homes, as stagnant water can promote mosquito breeding. Utilizing mosquito nets and repellents can be effective preventive measures.

Vaccination remains an important line of defense against influenza; however, there is currently a shortage of the trivalent vaccine, with quadrivalent vaccines being available. Dr. Kumar emphasizes the need for addressing this supply issue to facilitate vaccination efforts.

As the monsoon continues, both healthcare providers and the public must remain vigilant to combat dengue and influenza effectively, ensuring health and safety in the community.
