Understanding Malaria: Etiology, Symptoms, and Treatment Strategies

Fogging and Space Spraying Fogging is done during outbreak situations or high transmission periods. This quickly kills adult mosquitoes but is a temporary solution.

B. Personal Protection Measures

Much can be done at the individual level to prevent mosquito bites.

Mosquito Repellents

  • DEET (N,N-Diethyl-meta-toluamide) based repellents are the most effective. These are applied to exposed areas of the skin. Picaridin and IR3535 are also good alternatives.

  • Repellent creams, lotions, or sprays can be used. It should be applied before evening time because Anopheles mosquitoes are active at night. Reapplication is required every 4-6 hours.

  • Natural repellents like citronella, neem oil, and eucalyptus oil are also effective to some extent but less so than synthetic repellents.

Protective Clothing Full-sleeved shirts and long pants should be worn, especially in the evening and at night. Light-colored clothes should be preferred because mosquitoes are more attracted to dark colors. Permethrin-based repellent can also be sprayed on clothes, which provides extra protection.

Other Measures

  • Window and Door Screens: Mesh screens should be installed on windows and doors to prevent mosquitoes from entering. The screens should not have holes.

  • Mosquito Coils and Vaporizers: Mosquito coils, liquid vaporizers, or electric mats can be used for indoor use. They should be used with proper ventilation.

  • Avoiding Outdoor Activities: As far as possible, outdoor activities should be avoided between dusk and dawn, as this is the peak biting time for Anopheles.

C. Community-Based Prevention

Awareness and collective action at the community level are very important.
