    Marshall Islands: Govt. move over Hep A outbreak

    The hepatitis A outbreak reported in last week’s post has now spread to at least 89 people, with more suspected cases undergoing testing.

It is a common infection in travellers and is a significant risk in most developing countries where sanitation and hygiene are lacking. A course of hepatitis A vaccine offers immunity that is 99%-plus effective and protects for 20-30 years. Travellers should also follow these guidelines for safe food and water.

    Chad: Unknown source of outbreak in SE

    The World Health Organization (WHO) has confirmed an outbreak of hepatitis E among people suffering from acute jaundice syndrome (AJS) in Am Timan, capital of the south-eastern region of Salamat. To date there have been 693 cases and 11 deaths – around half of those tested were positive for Hep E infection.

    The number of avian influenza outbreaks and the different strains of the virus involved are concerning the World Health Organization (WHO), with the director-general, Dr Margaret Chan, issuing a warning this week. Dr Chan also spoke of novel bird flu strains (such as H5N6), which become virulent through gene-swapping (this strain has killed humans in China as late as December 2106). This comes as the total of H7N9 strain cases reported in the first 2 weeks of January hit 111. Hong Kong's Centre for Health Protection (CHP) has been monitoring the situation and cautioned that the current winter season is “progressing much faster than the situation last winter." Read more.

    Advice for travellers: Human H7N9 cases continue to be reported in mainland China, possibly linked to the sale of poultry. However, there has been no sustained person-to-person transmission.

However, Australians visiting the popular destination should be aware of the importance of avoiding contact with wild and domestic animals – especially dogs, the main source of infection.

    Mexico: Dengue mozzie hits the heights

    While dengue fever, Zika virus and chikungunya are present in Mexico, until now the risk of infection has been restricted to regions under 1,700 metres above sea level (masl) as they offer the best conditions for the vector, the Aedes aegypti mosquito. Now, a recently published study has released details of the discovery of the insect in 2 popular localities of Mexico City in 2015. The capital has not previously been a likely habitat of the insect due to its elevation (2,250masl) which gives the city its cool and dry climate. Read more (study abstract).

    Puerto Rico: 1 in 20 people exposed to Zika infection

    The majority of the 112 new Zika virus infections reported in US territories last week were in Puerto Rico, where some specialists in the field believe up to 20 percent of the population has been infected. Read more.

    Advice for travellers: Zika’s symptoms include a rash, pain in the joints, and the eye condition, conjunctivitis lasting 4-7 days. Long-term ill-effects are rare, although the joint pain may linger for weeks, even months. Like dengue and chikungunya, Zika is spread by Aedes mosquitoes which bite by day and are found in urban setting, including leafy gardens and outdoor restaurants – even in upmarket hotels and resorts. Transmission of Zika virus has also occurred during pregnancy, breastfeeding, sexually and also through blood or blood products. Travellers should take particular care to avoid being bitten just after sunrise and just before sunset, the main feeding time for Aedes mosquitoes. All travellers, but particularly pregnant women or those planning pregnancy, should seek medical advice before travel to Zika-affected areas. Read information on smartraveller (DFAT).

    Authorities are carrying out vaccination campaigns ahead of a predicted outbreak of meningococcal A disease.

Parts of northern Uganda lie at the eastern end of the so-called African Meningitis Belt. Read more.  

    Advice for travellers: Meningococcal meningitis is an acute bacterial disease transmitted from person-to-person through close (kissing, sharing eating utensils) or extended contact. Risk factors include extensive travel in crowded conditions or extended contact with local people in crowded places. South Sudan lies in North Africa’s ‘meningitis belt’, where meningitis outbreaks occur in the dry season (Dec-April) and just prior to the rainy season (May-June). If you plan to visit this region, call Travelvax Australia’s free travel health advisory service (1300 360 164 - toll-free for landlines) for further advice. Read more about Men. meningitis.

    Australia: Imported measles for VIC and NSW

    Anyone who has visited areas near Rowville in Victoria and the Macleay Valley in NSW recently is asked to be on alert for symptoms following the notification of measles infections to local health authorities. The Victorian cases (2) had travelled on a flight from Kuala Lumpur and were possibly infectious at that time; the NSW case had also contracted the infection while overseas. Measles symptoms include fever, malaise, cough, cold symptoms and conjunctivitis, followed by a rash that starts on the face before becoming widespread. As noted in the Australian Immunisation Handbook, measles is often a serious disease that leads to acute encephalitis in one in 1,000 cases. It is highly infectious.  

    Advice for travellers: Measles is a highly contagious virus and can cause serious illness in people of all ages. The majority of the rising number of cases reported in Australia are linked to overseas travel - both developing and developed countries.
