Mumbai has witnessed a significant reduction in dengue and malaria cases this monsoon season, attributed to the proactive efforts of the Brihanmumbai Municipal Corporation (BMC). Data indicates a promising trend, with fewer cases reported in June and July 2024 compared to the same months last year.
BMC data shows a dramatic drop in dengue cases, from 353 in June 2023 to just 93 in June 2024. Although July saw an increase to 535 cases, this still marks a 22% decrease from July 2023’s 685 cases. Similarly, malaria cases reduced slightly from 721 in July 2023 to 717 this July, despite a seasonal spike from June’s 443 cases. The monsoon season typically exacerbates the spread of vector-borne diseases due to the creation of mosquito breeding sites in stagnant water. Experts explain that the high humidity and frequent rainfall during this period provide an ideal environment for mosquitoes, leading to an increase in disease transmission. “The high humidity and frequent rainfall during this period create an ideal environment for mosquitoes, leading to more cases of these diseases,” said a Health Officer at BMC.
Despite the seasonal uptick, the overall downward trend underscores the effectiveness of BMC’s public health measures. Notably, the number of civic reporting units has expanded dramatically, from 22 to 880, improving the detection and management of these diseases. Medical professionals caution that the monsoon season, particularly in August, is likely to see a further rise in cases, a general physician, noted, “Continuous rainfall washes away mosquito breeding sites. However, once the rain stops and temporary water bodies form, mosquitoes exploit these stagnant waters to lay eggs. This often leads to a surge in mosquito-borne diseases in the months following intermittent rain, such as August.”
Interestingly, cases of gastroenteritis, another common monsoon-related illness, have decreased from 1,767 in July 2023 to 1,239 in July 2024. However, there was a notable increase from June 2024, which recorded only 722 cases. Data from the Indian Journal of Paediatrics indicates that children under five are particularly vulnerable, with up to 50% of paediatric hospital admissions during the monsoon linked to gastrointestinal infections. Official at Asian Institute of Medical Science, highlighted the impact of water-logging on drinking water quality and food safety, increasing the risk of gastrointestinal infections. “Water-logging severely affects the quality of drinking water and food, increasing the risk of gastrointestinal infections such as diarrhoea, vomiting, and abdominal pain. It is crucial to remain vigilant and implement preventive measures,” he advised.
Conversely, swine flu cases have surged by approximately 51.89% compared to July 2023, rising from 106 to 161 cases. Statewide data from January to July 2024 highlights significant improvements in disease management, with malaria cases dropping from 16,159 in 2023 to 7,447 in 2024, and deaths decreasing from 29 to six. Dengue cases also fell from 6,159 to 4,965, with fatalities reducing from 59 to three. Chikungunya cases decreased from 1,702 to 1,075, with no deaths reported in either year.
These statistics reflect the positive impact of BMC’s efforts in disease prevention and control. However, continued vigilance and proactive measures remain crucial as the monsoon season progresses, ensuring the health and safety of Mumbai’s residents.
