Specific Vaccine Information
- Typhoid – Typhoid, caused by Salmonella Typhi, is primarily transmitted through tainted food and water. Protection against this disease involves vaccination combined with good hygiene and careful food consumption.
- Hepatitis A – Hepatitis A is a contagious liver infection caused by the hepatitis A virus, typically spread through ingestion of contaminated food or water, or close contact with an infected person. Symptoms include fatigue, stomach pain, and jaundice. The hepatitis A vaccine provides effective prevention against the virus. It is administered in a series of shots, usually starting in childhood, and is recommended for travel to areas with high infection rates.
- Japanese Encephalitis – Japanese encephalitis is transmitted by mosquitoes and causes neurological issues. It can be prevented through mosquito management, protective attire, and vaccination. Vaccination is key to prevention for travelers to effected regions.
- Chikungunya – Chikungunya, carried by Aedes mosquitoes, can be prevented through use of repellents, netting and vaccination.
- Rabies – Rabies is a life-threatening viral infection transmitted primarily through bites and scratches from infected animals. Vaccination is the key to prevention, offering pre-exposure protection to high-risk individuals and post-exposure treatment for those exposed to rabies.
- Hepatitis B – The hepatitis B virus causes liver infection, spreading through contact with infected bodily fluids. Prevention measures include safe practices and, notably, hepatitis B vaccination. This vaccine effectively triggers the immune system to produce antibodies, offering reliable, long-term protection against the virus.
- Measles, Mumps, Rubella (MMR) – Measles, mumps, and rubella are viral infections that can spread through close contact and respiratory droplets. Vaccination is the most effective way to halt their transmission. The MMR vaccine, given in two doses, strengthens immunity, reducing the chances of contracting and spreading these diseases.
Malaria in Cambodia
Malaria is present in all regions of Cambodia. Travelers are advised to take antimalarials to protect themselves from infection. Atovaquone, doxycycline and tafenoquine are recommended for travelers to the region. Malaria parasites in Cambodia are resistant to chloroquine and mefloquine. Speak with your travel health specialist to identify which antimalarial is best for your trip and medical history.
A Japanese encephalitis vaccine is recommended for some travelers. This is especially true if you will be staying longer-term or visiting rural areas.
Travelers should also take steps to avoid mosquito bites and mosquito-borne disease like malaria and dengue. Share your itinerary with a travel medicine specialist to see if there are other steps you can take to prevent malaria, including antimalarials.
