As cities across India report an alarming surge in dengue cases, the global scenario is equally concerning. In 2024, a record number of dengue cases have been recorded around the world, with countries like Brazil and others in South America worst affected. According to the World Health Organization (WHO), dengue cases have steadily increased yearly. The rapid spread of mosquito-borne diseases like dengue and chikungunya is posing a significant public health threat, and understanding how these diseases spread their symptoms, and ways to prevent them is crucial for public safety.
Globally, more than 12 million dengue cases and 6,991 deaths were recorded by August 2024, according to WHO's global dengue surveillance data. This figure is already more than double the 5.27 million cases recorded in all of 2023, which set a new record. Before 2023, global dengue cases hovered between two to three million annually over the past decade.
Experts suggest that even the current record numbers are likely an undercount, as not all countries—India included—report their complete data to global surveillance networks. Additionally, some dengue patients may not get tested or reported to health authorities, further masking the true extent of the outbreak.
India, too, is witnessing a sharp increase in dengue cases. By the end of June 2024, over 32,000 dengue cases and 32 deaths were reported across the country, according to the National Vector Borne Disease Control Programme. In just two months, this number is believed to have escalated drastically.
The geographic spread of dengue within India is also expanding. The disease, once limited to just eight states and Union Territories (UTs) in 2001, has been reported in every state and UT as of 2022, with Ladakh confirming its first-ever cases last year. This increased reach can be attributed to factors such as urbanization, changes in climate, and the growing adaptability of mosquito species.
Several factors are contributing to the rise in dengue cases both globally and in India. Some of these include:
Both dengue and chikungunya are transmitted by the Aedes mosquito and share similar early symptoms. Here’s what to look for:
Both diseases can have severe implications if not identified early. It’s important to seek medical attention at the first sign of symptoms to manage these infections effectively.

In addition to dengue and chikungunya, India is also seeing a worrying increase in swine flu (H1N1) cases this year. Swine flu, though not transmitted by mosquitoes, has similar flu-like symptoms and can lead to serious respiratory problems if left untreated. With multiple viral diseases circulating, the public needs to remain vigilant and follow preventive measures to safeguard their health.
Here are some steps you can take to reduce the risk of mosquito-borne infections:
India's surge in dengue and chikungunya cases serves as a reminder of the importance of preventive measures and early detection. The rapid spread of these diseases underscores the need for continued public health efforts, improved mosquito control, and community awareness. By taking proactive steps, individuals can protect themselves and help reduce the impact of these dangerous infections.
