Although yellow fever does not occur in Laos, an official yellow fever vaccination certificate may be required depending on your itinerary.
- Requirement: A vaccination certificate is required for travelers coming from countries with risk of YF transmission.
Depending on your itinerary, your personal risk factors, and the length of your visit, your health care provider may offer you vaccination against hepatitis A, hepatitis B, influenza, Japanese encephalitis, measles, mumps, rubella, rabies, or typhoid fever. Routine immunizations, such as those that prevent tetanus/diphtheria or "childhood" diseases, should be reviewed and updated as needed.

High risk exists throughout the country, with moderate risk in deluxe accommodations. Food and beverage precautions may reduce the likelihood of illness.
Travelers should carry loperamide for self-treatment of diarrhea and, if risk is moderate to high, an antibiotic to add if diarrhea is severe. Consult a knowledgeable health care provider regarding which antibiotic is appropriate for you and most effective for your destination.

Other Disease and Health Risks
The material below includes information from the U.S. Department of State (DOS), U.K. Foreign & Commonwealth Office (FCO), Global Affairs Canada (GAC), and Australia's Department of Foreign Affairs and Trade (DFAT), as well as from additional open-source material. Standard safety precautions that apply to all international travel can be found in the Library article Safety and Security.
Consular Travel Advice
Due to ongoing violence, Canada (GAC) advises avoiding travel to Xaisomboun Province. U.S. (DOS), U.K. (FCO), and Australia (DFAT) advise reconsidering travel (or avoiding nonessential travel) to Xaisomboun Province.
No intrinsic risk of attack by terrorist groups exists, but unforeseen attacks are possible.
Risk of violent crime (armed robbery, sexual assault, carjacking, and murder) and high risk of petty crime exist in Vientiane, Luang Prabang, Vang Vieng, and other cities; Phou Khao Khouay National Park; and prior to and during local festivals and events.
Scams involving motor vehicle rentals have been reported.
Protests and demonstrations may infrequently occur and have the potential to turn violent without warning.
A dangerous security environment exists in Xaisomboun Province and in areas bordering Burma.
Landmines and other unexploded ordnance are present in Luang Prabang and Xiangkhouang provinces and in areas bordering Vietnam (including areas along the former Ho Chi Minh trail).
Hazardous water conditions (including currents, tides, and undertows) may occur, especially in the Mekong River. Heed posted warnings, and avoid beaches that are not patrolled. Do not swim alone or after dark, and do not walk on any beach after dark.
Passenger boats may be unsafe, including speedboats on rivers, especially the Mekong River. Decline water transportation in vessels that appear overloaded or lack personal flotation devices or life jackets.
Basic safety standards for recreational water activities (including rafting, kayaking, and tubing) are often not in place. Rent water sports equipment from reputable operators.
Basic safety standards for adventure activities (including recreational off-roading and ziplining) are often not in place. Travelers should only use reputable adventure-sport operators for activities and equipment rentals.
High risk of traffic-related injury or death exists. The road-traffic death rate is 12 to 24 per 100,000 population. The rate is < 10 in most high-income countries. Speed laws are poorly enforced. Driving at night is not advised. Seek local advice before traveling on roads outside urban areas after dark.
Due to security concerns, travel on portions of Route 13 (from Kasi, Vientiane Province to Phou Khoun, Louangphabang Province), the "new road" (from Road 4 junction to Kasi, Vientiane Province), Route 7 (from Phou Khoun, Louangphabang Province to Phonasava, Xiangkhouang Province), and Route 6 (near Sam Nuea, Houaphan Province) is unsafe.
Many taxis are unsafe. Use taxis from official ranks or dispatched via smart phone app or radio from a reputable company. Ascertain the license or identification number of the dispatched vehicle.
Traffic flows on the right-hand side of the road. Travelers (including drivers and pedestrians) accustomed to traffic moving on the opposite side should be vigilant when navigating traffic.
The monsoon season is from May through November, coinciding with the typhoon season. Floods, mudslides, and landslides may occur, especially along the Mekong River.
