Mosquito-borne diseases may cause serious illness. You can protect yourself and your family by getting rid of mosquito breeding sites (i.e., areas with standing water) around your home and by taking steps to protect yourself from mosquito bites (like using mosquito repellent).
Mosquito-borne diseases are not felt to be an immediate threat in Hawaii-e.g., because travelers are usually vaccinated (yellow fever) or disease spread requires a sick bird to travel all the way from the mainland (West Nile virus). Some mosquito-transmitted diseases (e.g., malaria or Japanese encephalitis virus) are not likely to ever be a threat because the mosquito species needed to spread the disease are not found in Hawaii. However, it is important for travelers to be aware of these serious diseases and where they occur in the world so they may protect themselves.
