Travel Vaccines and Advice for Zimbabwe

• Typhoid – Salmonella Typhi causes typhoid, a potentially life-threatening illness spread through contaminated food and water. Vaccination is a critical preventive measure, especially for travellers heading to endemic regions or individuals with an increased risk of exposure.
• Cholera – Cholera, a diarrheal illness triggered by Vibrio cholerae, spreads through contaminated water and food. Preventing cholera entails sanitation, hygiene, and safe food practices. The PHAC recommends cholera vaccination for travellers in high-risk areas and outbreak responses as an effective preventive measure against this infectious disease.
• Hepatitis A – Hepatitis A, caused by the hepatitis A virus (HAV), is a contagious liver infection. It spreads through contaminated food, water, and close contact. Preventive measures include vaccination, good hygiene, and avoiding raw shellfish. The hepatitis A vaccine is highly effective, requiring two doses for long-term protection.
• Rabies – Rabies is a deadly viral disease that affects mammals and spreads through the saliva of infected animals, primarily through bites or scratches. Preventing rabies involves vaccinating pets, avoiding contact with wild animals, and seeking immediate medical attention if exposed. The rabies vaccine is a crucial preventive measure that stimulates the immune system to produce antibodies against the virus.
• Hepatitis B – The hepatitis B vaccine is a potent shield against this liver virus, recommended for all travellers and crucial for healthcare workers. Alongside vaccination, practicing safe sex and avoiding needle sharing are essential in hepatitis B prevention.
• Measles, Mumps, Rubella (MMR) – Measles, mumps, and rubella are contagious viral infections, causing various symptoms and complications. To prevent them, vaccination is key. The MMR vaccine, given in two doses, safeguards against all three diseases and helps establish herd immunity, reducing the risk of outbreaks.

Antimalarials are recommended for travellers to all regions of Zimbabwe. Chloroquine resistance is present in the country. Atovaquone, doxycycline, mefloquine and tafenoquine are suggested as antimalarials if travelling to the region. Consult with a travel health specialist on which antimalarial will best fit your needs.

Bug bite prevention strategies involve wearing appropriate clothing and utilizing EPA-approved repellents such as DEET or picaridin, as suggested by the PHAC. Stay cautious during peak bug activity periods, clean the affected area, refrain from scratching, and consider over-the-counter remedies while promptly consulting a healthcare professional for severe reactions.

Safeguard your health while abroad by consuming cooked and hot foods, opting for bottled or sealed drinks, and practicing proper hand-washing. Limit your exposure to risky local dishes. To prevent travellers’ diarrhea, maintain these precautions: eat carefully prepared foods, avoid untreated water, sanitize your hands, consider probiotics, and exercise caution with unfamiliar cuisine.

Altitude sickness, also known as acute mountain sickness (AMS), arises at high elevations due to decreased oxygen levels. To prevent AMS, ascend gradually, stay hydrated, and consider medications like acetazolamide. If symptoms like headaches or fatigue develop, descend to lower altitudes for rest and recovery, seeking medical help if necessary.

• African Sleeping Sickness – African Sleeping Sickness, caused by parasites transmitted through tsetse fly bites in Africa, can be prevented by insect repellent, and avoiding fly-prone areas.
• African Tick-Bite Fever – African Tick-Bite Fever (ATBF) is a disease transmitted through tick bites in sub-Saharan Africa. Preventive measures include wearing protective clothing, using insect repellent, and performing tick checks. Consult a healthcare professional before travelling to endemic areas.
• Crimean-Congo Hemorrhagic Fever – Crimean-Congo Hemorrhagic Fever, which spreads through ticks and human-to-human contact, can be mitigated by practicing tick bite prevention. Vaccinations against the disease are in development.
• Dengue – Dengue fever, transmitted by Aedes mosquitoes, significantly impacts global health, affecting up to 400 million people yearly. Without specific antiviral treatments, prevention through avoiding mosquito bites is key. Repellents and nettings are recommended.
• Marburg Hemorrhagic Fever – Combating Marburg Hemorrhagic Fever involves ongoing research on vaccination, a crucial tool in prevention. MHF transmission stems from contact with infected animals and individuals, underscoring the significance of protective measures.
• Rift Valley Fever – To prevent Rift Valley Fever, vaccination of livestock is crucial, along with controlling mosquito populations and ensuring safe animal handling practices. Public health education plays a vital role in raising awareness about RVF risks.
• Schistosomiasis – Schistosomiasis, caused by parasitic flatworms, is prevalent in areas with contaminated freshwater sources. Prevention involves staying out of potentially infected waters and using protective clothing. Recognizing symptoms such as fever and seeking medical help promptly is crucial for diagnosis and treatment.
