Weekly round-up of the world's travel health news from Nomad
Malaria claimed 185 lives in the state from April 2010 to March 2011, which is the highest annual number of casualties from the disease reported in the last seven years. Of the 185 casualties, Mumbai alone accounted for 137.
The National Malaria Control Programme (NMCP) has declared a malaria outbreak in the Sidvwashini area of Northern Hhohho and surrounding locations at Masutaneni, Nya-katfo, and Ngonini. Over 20 malaria cases have been detected in the area through community screening and have been referred for treatment to the local health facility.Although investigations are still ongoing, the outbreak was likely due to someone who travelled outside the country and became infected after being bitten by malarial mosquitoes. When the traveller returned to the community, he/she was bitten by local mosquitoes, which transmitted malaria to surrounding neighbors.
Mosquitoes are common in the Sidvwashini area due to stagnant water related to agricultural operations.
Health authorities say they have detected another case of malaria in the Torres Strait. Four people became ill on Saibai and Dauan islands last month and authorities were optimistic the outbreak had been contained. But a fifth case of malaria has now been detected.
Advice to travellers
Travellers to the affected area should seek expert advice before they travel regarding the most suitable form of malaria tablets for their trip and medical history (if tablets are required). Always wear 20-50% DEET on all exposed skin, sleep under a mosquito net and wear long clothing to protect you. Malaria carrying mosquitoes generally bite between sunset and sunrise.

Dengue fever is spread by daytime biting mosquitoes normally from sunrise to sunset and is more common in urban areas. It causes a high ‘breakbone’ fever (pain all over), accompanied with headache, rash. It lasts a few days and will resolve itself. If caught a second time it has a two per cent chance of developing into Dengue Haemorrhagic fever which can be fatal. There is currently no vaccine available and therefore insect bite avoidance is essential.
The Health Department is warning about the ongoing risk posed by a potentially deadly soil disease, which has infected 56 people in the Northern Territory this wet season. Melioidosis claims a number of lives each year in the Territory but its impact has been more significant in the past two wet seasons with a record number of infections, including some in Central Australia.
Advice to travellers
Melioidosis is a disease caused by a bacteria that resides in soil and warm waters of rivers, seas and plantation paddy fields. It is acquired mainly via skin penetration but also by the respiratory route and by drinking contaminated water. Symptoms may include pain in chest, bones, or joints; cough; skin infections, lung nodules and pneumonia.
Travellers to affected areas (mainly Asia and Australia) should avoid bathing or walking in rice paddies, still waters, plantations and other water logged soils other than when wearing protective garments.
