Mumbai: Cases of mosquito-borne diseases, including Malaria, Dengue and Chikungunya, are reportedly increasing across Mumbai amid intermittent monsoon rainfall. Residents in several parts of the city have raised concerns over mosquito breeding and alleged delays in fumigation and other preventive measures by the Brihanmumbai Municipal Corporation (BMC).
Residents say stagnant water in residential areas, construction sites and other locations has created favourable conditions for mosquito breeding. Some citizens have also questioned whether preventive fogging and pest-control measures were initiated early enough to control the spread of vector-borne diseases.
Residents Demand More Fogging and Mosquito-Control Measures
Residents of areas such as Juhu Koliwada and Cuffe Parade have expressed concerns about increasing mosquito activity and rising cases of Malaria and Dengue.
A Juhu Koliwada resident said that fumigation and awareness posters appeared in the area only after several residents were diagnosed with mosquito-borne diseases. According to residents, preventive action earlier in the monsoon season could help reduce mosquito breeding and disease transmission.
Housing society representatives have also reportedly approached civic authorities seeking additional fumigation and mosquito-control measures in their neighbourhoods.
Residents say mosquitoes have become particularly troublesome after sunset, making it difficult for people to spend time outdoors. Watchmen and other people who remain outdoors for extended periods are among those facing greater exposure.
Stagnant Water Remains a Major Challenge
One of the major challenges in controlling mosquito populations is the presence of stagnant water.
BMC Executive Health Officer Dr Santosh Gaikwad said the civic body faces difficulties in addressing stagnant water in certain locations. Water can accumulate on blue tarpaulin sheets covering slum settlements, while inaccessible locations, including unused textile mill premises, can also become potential mosquito-breeding sites.
Construction sites, open containers, puddles and poorly drained areas can similarly provide breeding grounds for mosquitoes when water remains stagnant for several days.
Experts have repeatedly highlighted the importance of eliminating stagnant water as part of mosquito-control efforts, particularly during the monsoon season.
Intermittent Rain Can Increase Mosquito Breeding
Dr Shalini Suralkar, Director of General Medicine at LH Hiranandani Hospital, said the combination of intermittent rainfall and periods of sunshine can contribute to mosquito breeding.
The changing weather conditions can leave behind pockets of stagnant water, while warmer conditions between showers may support mosquito development. Extensive construction activity in different parts of Mumbai can add to the number of locations where water accumulates.
This makes regular inspection and removal of stagnant water an important part of preventing mosquito-borne diseases.
Who Is at Higher Risk of Severe Dengue?
According to Dr Suralkar, certain groups may be more vulnerable to developing severe illness from Dengue.
These include:
- Young children
- Elderly people
- Pregnant women
- People with diabetes
- People with heart disease
- Individuals with chronic kidney disease
- People with chronic liver disease
- People with other underlying health conditions
People who have previously had Dengue may also require particular attention if they develop symptoms again.
Symptoms That Should Not Be Ignored
Common symptoms associated with mosquito-borne infections can include fever, headache, body aches, weakness and chills, although symptoms can vary depending on the illness.
People experiencing persistent or high fever, severe weakness, unusual bleeding, breathing difficulties, severe abdominal pain, persistent vomiting or other concerning symptoms should seek medical attention promptly.
Residents should avoid self-medication and consult a qualified healthcare professional when symptoms suggest a possible mosquito-borne infection.
What Can Residents Do to Prevent Mosquito Breeding?
While civic authorities play an important role in vector control, residents can also reduce mosquito-breeding opportunities around their homes and buildings.
Simple preventive steps include:
- Remove stagnant water from containers, flowerpots and other household items.
- Keep water-storage containers properly covered.
- Regularly clean drains and areas where water can accumulate.
- Ensure construction sites do not have exposed stagnant water.
- Use mosquito nets, screens or appropriate repellents.
- Wear clothing that provides greater protection from mosquito bites, particularly during peak mosquito activity.
- Report mosquito-breeding sites to the relevant civic authorities.
Mumbai’s Mosquito-Control Challenge
The rise in Malaria and Dengue concerns during the monsoon highlights the importance of continuous mosquito-control efforts rather than relying only on fumigation after cases are reported.
Fogging can be one component of mosquito control, but eliminating breeding sites and preventing stagnant water accumulation are also essential. Cooperation between civic authorities, housing societies, construction-site operators and residents can help reduce mosquito populations.
With intermittent rainfall continuing to create potential breeding sites, regular monitoring and timely preventive action remain important to limit the spread of Malaria, Dengue and Chikungunya in Mumbai.
FAQs
Why are mosquito-borne diseases increasing during the monsoon in Mumbai?
Intermittent rainfall can create stagnant-water pockets, which can become breeding sites for mosquitoes. Construction activity and inadequate drainage can further contribute to the problem.
Does fogging prevent Dengue and Malaria?
Fogging can help reduce adult mosquito populations in targeted areas, but eliminating stagnant water and mosquito-breeding sites is an important part of long-term prevention.
Who is at higher risk from severe Dengue?
Young children, elderly people, pregnant women and people with certain underlying health conditions may be at greater risk of severe illness.
How can residents prevent mosquito breeding?
Residents can remove stagnant water, cover water containers, clean drains regularly and report potential mosquito-breeding sites to civic authorities.
When should someone consult a doctor?
Anyone with persistent or high fever or concerning symptoms should seek medical advice promptly, particularly if they are in a higher-risk group.
