NT Health has warned that recent wet weather conditions have caused mosquito numbers to explode and that Territorians should take the necessary precautions to protect themselves from contracting diseases this coming long Easter weekend.

The highest risk period for severe mosquito-borne diseases such as Murray Valley encephalitis (MVE) and Japanese encephalitis (JE) is from now until June.

Last year, eight cases of MVE were recorded in the NT, with one fatal case. Three cases of JE were recorded, with one fatal case in 2021 and 2022.

“To ensure the best protection from mosquito-borne diseases, it’s important to cover up, use insect repellents and avoid areas where mosquitoes are active, such as swamps and wetlands. Infants and children need to be protected,” NT Health Director of Medical Entomology Nina Kurucz said.

“Following the significant rainfall associated with Cyclone Megan, mosquito numbers are expected to increase dramatically this week across all regions.

“This is because rain, high temperatures and humidity create ideal breeding conditions for mosquitoes.”

The Easter long weekend is a timely reminder to stay protected from mosquitoes, with many people planning to participate in outdoor activities and camping trips, Ms Kurucz said.

NT Health said people should ensure the protection of infants and young children from mosquitos; wear long-sleeved shirts and pants, socks and shoes; use insect repellent containing DEET, picaridin or oil of lemon eucalypt; avoid areas where mosquitoes are active, especially after sundown; and use mosquito-proof tents when camping, to minimise the chance of being bitten.

Symptoms of mosquito-borne diseases include headaches, fever, nausea and vomiting, muscle aches, seizures, tremors or fits and can progress to delirium, coma, permanent brain damage or death.

Anyone concerned about symptoms should contact their local healthcare provider.

JE can also be prevented with vaccines. NT residents may be eligible to receive a free vaccine.
