Malaria is known as an infectious disease spread by Anopheles mosquitos, which is current on some continent, especially in tropic zone. These mosquitos are active in the evening-night period.

Currently, the so called Aedes mosquitos are more widespread, that are responsible for spreading for example yellow fever, Zika, West Nile and Dengue viruses. These mosquitos are active by daytime.

Im some cases there is a special prevention available, for example yellow fever vaccination or malaria prophylaxis. Before prescribing any preventive medicine, malaria risk assessment must be done by considering facts such as destination, duration of stay, night accommodation type, extent of outdoor activities.

Nonspecific protection – avoiding mosquito bites – has great relevance under every condition. There are physical and chemical methods, e.g. using nets, tents impregnated with permethrin, wearing long clothes, applying mosquito repellents externally. Repellents offering many hours of protection are preferred: those containing DEET, IR3535, and Picaridin (KBR 3023).
