Hong Kong dengue bulletin stops short of Bali Zika alert
A Hong Kong Travel Health Service bulletin reiterates general dengue precautions for travellers to Indonesia but does not issue a Zika alert for Bali or provide Bali-specific dengue figures or trends.

Denpasar — A recent travel-health bulletin from Hong Kong’s Centre for Health Protection advises general dengue precautions for travellers to Indonesia, but it does not issue a Zika alert for Bali or provide Bali-specific dengue figures.
The bulletin appears under the headline “Bangladesh: Dengue Fever [Update]” on Hong Kong’s Travel Health Service outbreak news page and focuses primarily on the dengue situation in Bangladesh. Within the wider travel advice, dengue is described as endemic in more than 100 countries across Africa, the Americas, the Eastern Mediterranean, Southeast Asia and the Western Pacific, including popular destinations such as Indonesia.
The dengue guidance lists Indonesia among places where travellers should take precautions against mosquito bites, but the text does not break down case numbers by Indonesian province or island. No specific totals for Bali are given, and there is no indication that the advice is tied to a new epidemiological development on the island.
What the Hong Kong bulletin says about dengue
According to the Travel Health Service, dengue fever is now endemic in over 100 countries worldwide, including Indonesia and several other Southeast Asian destinations. Travellers planning to visit these areas are advised to adopt mosquito-avoidance measures, such as using insect repellent and wearing long sleeves and trousers.
The bulletin directs readers to a detailed dengue situation report hosted by Hong Kong’s Centre for Health Protection, which compiles imported case data for Hong Kong and overseas figures from national health authorities. However, that material aggregates Indonesia-wide data and does not provide a separate figure for Bali.
The practical advice is general: anyone travelling to areas where dengue fever is prevalent should take precautions, and travellers who feel unwell after returning should seek medical advice promptly and tell clinicians about their recent travel. The Hong Kong guidance does not recommend cancelling trips to Bali or Indonesia solely on the basis of dengue risk.
What the notice does not say about Zika
The Hong Kong bulletin does not identify any Zika cases in Bali, does not declare a Zika outbreak in Indonesia and does not announce a Zika-specific travel recommendation for the island. It does not attribute a Zika warning to the U.S. Centers for Disease Control and Prevention (CDC), the World Health Organization (WHO), Indonesia’s Ministry of Health or Bali’s provincial health authorities.
Separate reporting indicates that the CDC has issued a Level 2 travel health notice for Zika linked to travel to Bali, advising pregnant people to avoid the island and other travellers to practise enhanced precautions. Indonesian media also report that the national Ministry of Health has publicly stated there are no confirmed Zika cases detected in Bali, despite the CDC notice.
Those Zika statements and responses come from other organisations and outlets; they do not appear in the Hong Kong Travel Health Service dengue bulletin, which is limited to general dengue risk and prevention advice.
Why dengue and Zika alerts should be kept separate
Dengue fever and Zika virus disease are different illnesses, even though both are transmitted primarily by Aedes mosquitoes. A general reminder to take dengue precautions in Indonesia therefore cannot be treated as evidence of a Zika outbreak or a Zika-specific travel notice for Bali.
In Indonesia, the CDC’s Zika notice and the responses from Bali’s health authorities and the Ministry of Health are being handled through separate channels and statements. Travellers considering medical or itinerary changes in relation to Zika or dengue should consult the latest advisories directly from their national health agencies, Indonesia’s Ministry of Health, Bali’s provincial health office and international bodies such as WHO.
The Hong Kong dengue bulletin remains a generic resource: it underscores that dengue is endemic in Indonesia and other tropical destinations and that travellers should protect themselves against mosquito bites and seek care if they become ill after returning home. It does not confirm a Bali-specific Zika alert or quantify current dengue trends on the island.
