Enhanced screening at Phnom Penh airport over hantavirus

On May 9, 2026, a senior Cambodian health official inspected preparations at Phnom Penh International Airport. The goal: strengthen health screening in response to the hantavirus outbreak affecting several countries. The World Health Organization (WHO) classifies this outbreak as low risk, but Cambodia decided to intensify screening at points of entry.

Measures include temperature checks, a health questionnaire, and increased monitoring of passengers from affected areas. No hantavirus cases have been reported in Cambodia to date.

If you travel via Phnom Penh airport, expect additional checks upon arrival. Allow extra time for border clearance. Domestic flights to Siem Reap are not subject to these enhanced measures.

For expats residing in Siem Reap, the risk remains very low. No travel restrictions are in place for Siem Reap province or the Angkor temples. Daily life is unaffected.

If you plan to travel via Phnom Penh:

• Arrive at the airport earlier than usual to account for checks.
• Have your passport and visa ready.
• Answer the health questionnaire honestly.
• If you have symptoms (fever, cough), report them to staff.

For expats already on the ground, no specific action is needed. Stay informed via official channels.

Don't panic: hantavirus is not a new virus, and WHO considers it low risk. Avoid sharing unverified information on social media. Rumors of border closures or quarantine are unfounded for now.

Beware of fake health workers who might try to scam you. Official checks are conducted by uniformed airport staff.

The situation is evolving. If the outbreak worsens, Cambodia could extend checks to other entry points, including the Poipet land border and Siem Reap airport. Monitor announcements from the Ministry of Health and WHO.

For now, the risk to expats remains negligible. Continue basic hygiene practices and stay informed through reliable sources.
