Dengue Fever: The Threat of the Asian Tiger Mosquito

A Global Health Concern

What is Dengue Fever?

Dengue fever is a viral infection transmitted by Aedes aegypti and Aedes albopictus mosquitoes.

Epidemiology

• Estimated 390 million infections annually worldwide.
• Approximately 500,000 severe cases that require hospitalization.
• Can be fatal in severe cases.

The Invasive Asian Tiger Mosquito

Aedes albopictus, the Asian tiger mosquito, has spread rapidly worldwide.

Characteristics:

• Aggressive daytime biter.
• Transmits dengue, Zika, and chikungunya viruses.
• Prefers to breed in artificial containers, such as tires and flower pots.

Malaria vs. Dengue Fever

Malaria is a more serious disease, but progress has been made in combating it.

Key Differences:

• Malaria is transmitted by Anopheles mosquitoes, while dengue is transmitted by Aedes mosquitoes.
• Malaria can be fatal if untreated, while dengue is usually non-lethal.
• There is no vaccine for malaria, but there is a vaccine for dengue.

Prevention and Control

Preventing Mosquito Bites

• Use insect repellent containing DEET, picaridin, or IR3535.
• Wear long sleeves and pants.
• Use mosquito nets and window screens.

Mosquito Control

• Eliminate mosquito breeding sites (e.g., standing water).
• Use mosquito traps and larvicides.
• Support community-based mosquito control programs.

Conclusion

Dengue fever is a major global health concern. The Asian tiger mosquito is a key vector of this disease, and its spread has led to an increase in dengue fever cases.

Prevention and control measures, such as mosquito control and personal protective measures, are crucial to combat dengue fever. By working together, we can reduce the impact of this disease on human health.
