According to the Director-General of the World Health Organization (WHO), Tedros Adhanom Ghebreyesus, the WHO has officially declared the Ebola outbreak in Central Africa a health emergency of international concern, requiring a coordinated response from multiple continents.
To date, the epicenter of the outbreak, the Democratic Republic of Congo, has recorded at least 51 confirmed cases of Ebola through in-depth testing. Epidemiologists from the WHO believe the actual scale of this Ebola outbreak may be much larger than the reported figures suggest.
International surveillance systems have noted that nearly 600 suspected cases are still awaiting confirmed test results, and approximately 139 other directly related cases are on a special medical monitoring list.
Although the risk index remains low when calculated globally, the volatile nature and rapid spread of this virus do not allow any healthcare system to be complacent. Identifying the source of infection and contact tracing on the ground remains challenging, prompting countries and territories as far away as Asia to proactively erect early disease prevention measures to thoroughly prevent the risk of this dangerous virus entering through air travel and border trade.
Many Asian countries are strengthening border controls and raising health response levels following emergency alerts.
In South Korea and China, authorities have mandated that all passengers arriving from or having traveled through areas affected by the outbreak, such as the Democratic Republic of Congo, Uganda, and South Sudan, must complete a detailed health declaration form before entry.
Any individual exhibiting clinical signs such as high fever, nausea, or identified as having epidemiological exposure to the source of infection will be immediately placed in temporary isolation and transferred directly to specialized medical facilities for further in-depth assessment.
The Hong Kong (China) authorities are proactively preparing the Penny's Bay quarantine facility on Lantau Island. This large-scale quarantine center, which was used effectively during the Covid-19 pandemic, has now been maintained and is ready to be activated to receive suspected or confirmed cases as soon as signs of the virus appear.
Tourists need to be truthful about their travel itinerary and health status to facilitate contact tracing.
In Singapore, Japan, Indonesia, and Nepal, the health monitoring process is extended to 21 days from the date passengers leave the affected area, which is also the maximum incubation period of the Ebola virus according to scientific studies. The Singapore Infectious Diseases Agency confirms that direct health checks will be conducted at border crossings for any passengers showing suspicious symptoms.
In South Asia, the Indian government has designated the National Institute of Virology in Pune as the primary testing center responsible for expanding rapid diagnostic capacity and ensuring accurate detection of cases in the shortest possible time.
In Vietnam, the Ministry of Health is closely monitoring every small change in the global pandemic situation, maximizing health quarantine measures at border crossings, especially at major international airports that receive transit flights from Africa. Remote body temperature measurement systems and temporary isolation rooms at border crossings are kept ready for operation 24/7.
Health experts advise people to carefully consider and closely monitor epidemiological information if they plan to travel to Central and East Africa.
To prevent the catastrophic spread of infectious diseases from distant sources, the Vietnamese Ministry of Health recommends that people entering the country with a travel history through affected areas proactively monitor their health strictly for 21 days. People must absolutely avoid direct contact with individuals suspected of having Ebola, and must not come into contact with the blood, bodily fluids, or personal belongings of infected individuals.
People are also advised to carefully consider and thoroughly research epidemiological information before deciding to travel to Central and East Africa at this time. For passengers who are required to travel through international border crossings, truthfully declaring their travel history and health status is a mandatory obligation to protect themselves and society.
People also need to raise their awareness of disease prevention by avoiding contact with people who have high fever, unexplained bleeding, and absolutely staying away from wild animals of unknown origin in disease-prone areas.
