Outbreaks of polio

There are polio outbreaks in a number of countries overseas. The current list of polio-infected countries is available on the Global Polio Eradication Initiative website.

The World Health Organization (WHO) recommends that all travellers to polio-affected areas be fully vaccinated against polio. Residents (and visitors for more than 4 weeks) from infected areas should receive an additional dose of OPV or inactivated polio vaccine (IPV) within 4 weeks to 12 months of travel.

The 3 October 2019 statement of the 22nd IHR Emergency Committee Regarding the International Spread of Poliovirus is available on the WHO website.

More information about the situation in infected regions can be found on the WHO website and the Global Polio Eradication Initiative website.

Japanese encephalitis

There is an outbreak of Japanese encephalitis (JE) in Australia. Information about the outbreak is available on the Australian Government Department of Health website.

Japanese encephalitis is a disease transmitted to humans by mosquitoes infected with the Japanese encephalitis virus. Most infections are asymptomatic or with mild symptoms, but occasionally (less than one percent of cases) it can result in severe disease and/or death. Initial symptoms are usually a sudden onset of fever, headache and vomiting and present about 5 to 15 days after infection. If you develop symptoms, have been in an affected region in Australia and think that you may have been infected with Japanese encephalitis virus, seek urgent medical assistance

Japanese encephalitis virus is not present in New Zealand.

If you are planning to travel to Australia or to another country with diseases transmitted by mosquitoes, the best protection is to avoid mosquito bites. Information on avoiding mosquito bites is available at avoiding bug bites while travelling.

A vaccine against Japanese encephalitis is available in NZ. However, vaccination needs to be planned in well in advance of the travel with travel health clinics.
