Delhi sees 4-year high in malaria cases this November
What's the story
Delhi has witnessed a spike in malaria cases this November, with 67 new infections reported. This is the highest number of cases for the month since 2021. The rise comes after a worrying trend in recent months, with 203 cases reported in September and 252 in October. The total number of cases for the year so far is 690. So far, however, no deaths due to malaria have been reported this year.
Dengue drop
Dengue cases decline significantly in Delhi
In contrast, dengue cases have declined sharply this year. To date, Delhi has reported 1,309 dengue cases, a steep decline from 4,978 in 2024 and 7,011 in 2023. The data up till mid-November reveals only 1,257 dengue cases compared to over 4,500 during the same period last year. However, two deaths due to dengue have been reported this year.
Malaria surge
Factors contributing to rise in malaria cases
Experts have cited several reasons for the rise in malaria cases. These include prolonged damp weather following the monsoon, more breeding grounds at construction sites, and potential lapses in mosquito larvae control efforts. Additionally, Anopheles mosquitoes, which transmit malaria, have become more active during cooler weather. To prevent mosquito bites, people are advised to use repellent sprays, wear long-sleeved clothing at night, and sleep under mosquito nets if windows are open or outside.
Disease symptoms
Symptoms of malaria and dengue
The symptoms of malaria include high fever, chills, headache, fatigue, nausea or vomiting, and muscle or joint pain. Dengue symptoms include sudden high fever, severe headache, pain behind the eyes, and joint/muscle/bone pain. If these symptoms worsen for over 24-48 hours, medical attention should be sought immediately. Public education drives, local clean-ups, and improved medical response systems contributed to a reduction in dengue infections and may prove effective against malaria as well.
