- Rabies – Preventing rabies involves avoiding contact with infected animals and ensuring timely vaccination. The rabies vaccine is a critical tool, offering protection through post-exposure prophylaxis (PEP) and preemptive vaccination for high-risk individuals like travelers.
- Hepatitis B – Hepatitis B, a liver infection transmitted through infected fluids, can be prevented through safe practices and the hepatitis B vaccine. The vaccine prompts the immune system to produce antibodies, offering robust and long-lasting protection against the virus.
- Measles, Mumps, Rubella (MMR) – Measles, mumps, and rubella are contagious diseases transmitted via respiratory droplets and touch. Preventing these illnesses is primarily achieved through vaccination, using the MMR vaccine. It’s administered in two doses and provides immunity against all three viruses.

Consult with a travel health specialist on which antimalarial will best fit your needs.

Although there is no risk of yellow fever in Laos, the government requires proof of yellow fever vaccination if you are traveling from a country with risk of yellow fever. This does not include the U.S.

What Is the Climate Like in Laos?
Laos has a tropical climate characterized by regular monsoon activity. Monsoons are most common during the rainy season from March through October, but varies based on locale.
Most of Laos sees a considerable amount of sun and heavy rainfall which can lead to uncomfortable amounts of humidity. But, mountainous regions have cooler and more temperate weather year-round.
- Pakse – Located in the southern region, it has a tropical savanna climate. Temperatures are particularly high in the months before monsoon season, which begins in March.
- Vientiane – Nestled in the northern-central region of the country, Vientiane is the capital of Laos. The city’s rainy season is from May through September with drier months from November through February.

How Safe and Secure Is Laos?
When traveling in Laos, it’s important to be aware of your surroundings and avoid suspicious people or areas. Respect the local customs and laws, like dressing modestly and not showing public displays of affection.
Keep your important documents in a safe place and don’t carry too much cash or valuable items with you. If you must travel at night, use a reputable transportation company and avoid traveling alone. Don’t buy drugs because it’s illegal, and the penalties can be severe.
Stay informed about any safety concerns or warnings from your embassy or local authorities and follow their recommendations. By using common sense and being respectful, you can enjoy a safe and enjoyable trip to Laos.
Is the Food Safe in Laos?
Laos boasts a large selection of unique cuisine. Most of this food is unfamiliar to the American palate, including Sai Uah (sausage) and Larb (a minced meat salad).
While most of these Asian delicacies are okay for consumption, take notice of how and where they are cooked. Diseases such as cholera, hepatitis A and typhoid spread in contaminated food and water.
Delicious-smelling street food, where meats are often cooked in the open-air, can be tempting. But, research which eateries are known for delivering high-quality options.

What Should I Take to Laos?
If you are going to travel to Laos, there are some important things to pack. Laos is a hot and humid country, so bring lightweight and loose-fitting clothes made of breathable fabrics, like cotton. It is also a good idea to pack comfortable shoes for walking on uneven terrain.
Laos is home to mosquitoes, so bring insect repellent to protect yourself from insect-borne diseases. Bring sunscreen with a high SPF to protect your skin from the sun’s harmful rays. Laos uses different power sockets, so you may need to bring a travel adapter.
It is also a good idea to bring any necessary prescription medications and a basic first-aid kit with essentials such as band-aids, antiseptic wipes, and pain relievers. Many places only accept cash, so bring enough cash to cover your expenses. Consider bringing a travel guidebook to help you navigate Laos and learn more about the country’s culture, history, and attractions. Finally, don’t forget to pack a camera or smartphone to capture your memories.
