Navigating Health Risks While Traveling Overseas: Expert Insights

As international travel resumes, health experts are reiterating the importance of remaining vigilant against infectious diseases, particularly COVID-19, in popular holiday destinations across Asia. With over 236,000 recent COVID-19 infections reported in South-East Asia, including more than 85,000 in Thailand alone, travelers must prepare adequately to minimize health risks during their travels.

The World Health Organization (WHO) has noted the emergence of new COVID-19 subvariants, including NB.1.8.1, which are contributing to increased case numbers in the region. According to Dr. Paul Griffin, an infectious diseases expert at the University of Queensland, “The risk of COVID is still significant—both while traveling and here in Australia.” He emphasizes that vaccination remains a crucial line of defense, yet current vaccination rates lag behind what is necessary for optimal protection.

Despite the ongoing pandemic, Australians are not hesitating to travel, with outbound travel increasing significantly. Reports from the Australian Travel Industry Association (ATIA) reveal that visits to Indonesia, Thailand, and Vietnam have risen by 16.4%, 19.7%, and 25% respectively in the year leading up to April 2025. ATIA Chief Executive Dean Long attributes this uptick to travelers prioritizing value and climate over health concerns, stating, “COVID is not really part of the decision-making process for most people.”

In light of these developments, health experts suggest several strategies for staying healthy while traveling. These include receiving up-to-date vaccinations at least two weeks prior to departure, practicing good hand hygiene, and wearing masks in crowded spaces. Additionally, Professor Griffin advises travelers, particularly older individuals or those with pre-existing conditions, to seek tailored medical advice before leaving.

Preparation is critical for those who do fall ill while overseas. Travelers are encouraged to pack a basic health kit that includes hand sanitizers, masks, and any necessary medications. If sickness does occur, the Australian Department of Foreign Affairs and Trade (DFAT) recommends seeking local medical assistance immediately and contacting travel insurance providers early to arrange treatment or coverage. DFAT can also assist in locating English-speaking medical professionals.

Travel insurance is essential, particularly as some policies may not cover pre-existing conditions or additional COVID-19-related expenses. Professor Griffin warns that many insurers have scaled back the extensive COVID protections that were introduced during the pandemic, making it vital for travelers to carefully review their policies. “If you can’t afford travel insurance, you can’t afford to travel,” Mr. Long asserts, underscoring the importance of having adequate coverage.

As travel continues to rebound, Australians are encouraged to remain informed about health advisories and to practice responsible travel habits to safeguard their health and well-being. For those planning trips to countries with rising COVID-19 cases, it is advisable to stay updated on local health measures and to monitor the situation closely through resources like Smartraveller, provided by DFAT.
