Thailand Mandates 21-Day Ebola Quarantine for Travellers from DR Congo and Uganda — Effective 27 May 2026

On 27 May 2026, Thailand's National Communicable Disease Committee — chaired by the Public Health Ministry and operationalised by the Department of Disease Control (DDC) — approved tightened entry measures for travellers arriving from or transiting through the Democratic Republic of Congo and Uganda. Both countries have been declared "dangerous communicable disease zones" for Ebola virus disease, unlocking the strongest set of controls available under Thai law.

The new measures took effect at 6:00 PM Bangkok time on the same day. Under the previous regime, arrivals from at-risk countries were simply kept under observation. Under the new regime, every qualifying arrival is now placed under a 21-day quarantine or isolation — the maximum incubation window for Ebola — and routed through a single airport for centralised screening.

The Department of Disease Control has been instructed to prepare quarantine facilities for arrivals from 6:00 PM on 27 May 2026. The table below contrasts the previous observation framework with the new mandatory regime.

Dr Montien Kanasawat, Director-General of the Department of Disease Control, said after the committee meeting: "I ask all travellers to provide their travel history truthfully so that disease prevention and control can be carried out effectively. I also ask the public to have confidence in Thailand's surveillance system, which is fully prepared in terms of personnel, medical supplies and high-level laboratories."

Thai officials have warned that travellers who disobey disease control orders face criminal penalties under the Communicable Diseases Act BE 2558 (2015). The penalties scale sharply depending on which order is breached.

The penalty regime is unusually severe for a public-health screening exercise — a deliberate signal from Thai authorities that quarantine compliance is not negotiable.

For the vast majority of UAE residents, this change has no practical effect — Thailand's standard visa-free, visa-exemption and e-Visa channels remain open as before for travellers whose recent itinerary does not include DR Congo or Uganda. The new screening applies only by travel history, not by passport nationality.

Dr Anek Mungaomklang, Deputy Director-General of the Department of Disease Control, confirmed that as of 26 May 2026, 53 travellers had entered Thailand from the affected countries (12 from DR Congo, 41 from Uganda) and that none had shown any symptoms. UAE residents who have moved between East Africa and Thailand in recent weeks should expect to be among future arrivals captured by the new screening.

Thailand's measures are part of a coordinated global response to a fast-moving Ebola outbreak in Central Africa. On 15 May 2026, the Democratic Republic of Congo's Ministry of Health officially declared an Ebola disease outbreak in the country's northeast. The outbreak is caused by the Bundibugyo virus — a rarer species of Ebola for which there is no approved vaccine and no approved treatment. On the same day, Uganda announced that the virus had crossed the border.

Two days later, on 17 May 2026, the World Health Organization declared the outbreak a Public Health Emergency of International Concern (PHEIC) — the highest alert level under the International Health Regulations. The WHO has reported that the outbreak may be spreading faster than originally thought, with hundreds of suspected cases and more than 130 reported deaths across multiple health zones.

1. 1Check your last 21 days of travel. If you have not been to DR Congo or Uganda in that window, no action is needed — your Thailand plans are unaffected.
2. 2If you have travelled to DR Congo or Uganda, plan to arrive at Suvarnabhumi (BKK) only. Other Thai international airports will not accept these arrivals under the new framework.
3. 3Budget for the 21-day quarantine. Expect to remain at a designated quarantine facility for the full 21 days, even if symptom-free.
4. 4Carry full travel-history documentation. Truthful declaration is mandatory; misrepresentation triggers separate offences under the Communicable Diseases Act.
5. 5If you are on humanitarian, NGO or business assignment in Central Africa with Thailand routing, consider an alternative stopover until the outbreak is downgraded.
6. 6Monitor the Department of Disease Control website and the WHO advisory feed for updates — the measures are subject to periodic review by the Thai authorities.

This update is based on publicly available information from Thailand's Department of Disease Control (via Nation Thailand reporting of Dr Montien Kanasawat and Dr Anek Mungaomklang), the World Health Organization, MSF and the US Embassy in Thailand, all verified as of 27 May 2026. Thailand has confirmed zero Ebola cases on its territory; the new measures are precautionary and apply only to travellers with a 21-day travel history that includes the Democratic Republic of Congo or Uganda.
