Dengue Cases Surge in Delhi: Symptoms, Risks, and Prevention Tips
Dengue Outbreak in Delhi
Recent statistics from the Municipal Corporation of Delhi (MCD) reveal that August saw the highest incidence of dengue cases this year, with numbers more than doubling compared to July. By August 29, the capital reported 311 dengue cases, alongside 119 malaria and 22 chikungunya cases. Interestingly, 52 dengue cases were also identified in April. Fortunately, there have been no fatalities linked to these diseases thus far.
Efforts to Control Mosquito Population
In response, the MCD is actively working to reduce the mosquito population. Inspections have been conducted in over 25 million households, revealing mosquito larvae in approximately 125,000 of them. Insecticides have been applied in around 575,000 homes, and legal notices have been issued to more than 90,000 residents. This article will delve into how dengue spreads and its symptoms.
Understanding Dengue and Its Symptoms
What is Dengue?
Dengue is a viral illness transmitted through the bites of infected mosquitoes found in tropical areas. It’s crucial to understand that dengue does not spread directly between people; rather, it is carried by mosquitoes. After recovering from one strain of the dengue virus, individuals gain immunity to that specific type but remain susceptible to the other three strains.
Symptoms generally manifest between 4 to 10 days following a mosquito bite and are often confused with the flu. Key symptoms include:
- High fever, potentially reaching 104°F
- Severe headaches and pain behind the eyes
- Muscle, joint, and bone pain
- Nausea or vomiting
- Swollen glands and a red rash on the skin
Most individuals recover within one to two weeks, although fatigue may linger for several weeks.
When Dengue Becomes Critical
Identifying Severe Dengue
While many recover within a week or two, some may experience prolonged weakness. The real concern arises when severe symptoms develop a day or two after the fever subsides. This condition, known as 'Severe Dengue' or 'Dengue Shock Syndrome,' occurs when blood vessels leak and platelet counts drop significantly. Serious warning signs include:
- Intense abdominal pain and ongoing vomiting
- Bleeding from the nose or gums
- Blood in vomit, urine, or stool
- Difficulty breathing, extreme fatigue, and persistent irritability
- Bruising or dark patches under the skin
Pregnant women with dengue are at a heightened risk of complications such as premature delivery or low birth weight.
Managing Dengue Symptoms
What to Do If You Have Dengue
Diagnosis of dengue is based on travel history and blood tests. While there is no specific treatment, symptom management is essential:
- Stay Hydrated: Drink plenty of fluids to prevent dehydration, which is a significant risk with dengue. Seek medical attention if you notice dry mouth, reduced urine output, or cold extremities.
- Choose Pain Relief Wisely: Use acetaminophen for fever and pain relief.
- Avoid Certain Medications: Steer clear of ibuprofen, aspirin, or naproxen, as these can increase the risk of internal bleeding.
In severe cases, hospitalization may be necessary for intravenous fluids and monitoring.
Preventing Dengue
Best Practices for Prevention
The most effective way to protect yourself from dengue is to avoid mosquito bites. Prevent water accumulation, as mosquitoes breed in stagnant water. Regularly change water in containers like animal troughs, old tires, and flower vases to keep them clean.
To keep mosquitoes at bay, install mesh screens on windows and doors or stay in air-conditioned environments. Dengue-carrying mosquitoes are most active during the morning and evening hours.
