Another case of a Buruli ulcer (flesh-eating disease) has emerged in the Far North, leading health officials to issue another warning about protecting against mosquitoes. Tropical Public Health Services acting director Dr Madhumati Chatterji said in both cases, there was most likely local exposure. “It is not known how the infection is contracted, there are various theories including the possibility of insect transmission,” she said. “While research is ongoing into how the infection is transmitted, people are advised to avoid contact with soil or water where possible, particularly in the Daintree/ Mossman area and to avoid mosquito bites by covering the body with clothing and using insect repellent.” Read more

Advice for travellers

Outbreaks of ‘Crypto’ are well documented, mainly as a result of swimming in swimming pools and water parks harbouring the parasite. While the parasite can be spread in several ways, swallowing contaminated drinking or recreational water is the most common. Cryptosporidium is a leading cause of water-borne disease in most developed countries, including Australia. For further information, see the NSW Health cryptosporidiosis factsheet.

However in the last 3 years there has been a change in transmission for YF in Brazil. During 2018, viral circulation continued during the period of low transmission (June to November).

Advice for travellers

Dengue is spread by two types of Aedes mosquitoes. Both breed close to dwellings, are found in shady areas and bite mainly during the daylight hours, making them difficult to avoid. Travellers should cover up with long-sleeved tops, long pants, and shoes and socks when mosquitoes are most active. Apply repellent containing an active ingredient, such as DEET, Picaridin, or PMD when outdoors to all exposed skin. Read more about dengue fever and preventing insect bites.
