To stay safe and secure abroad and to be prepared in
case things go wrong, it is important to take a few simple
precautions before you go and while you are there.
Diseases like Hepatitis A can be caught from drinking or swimming in contaminated water. Unless you know the water supply is safe only use bottled, boiled or sterilised water, even for cleaning your teeth and avoid ice in drinks. Contaminated food is the most common
source of many diseases abroad. You can help to prevent it by following these guidelines:
Travellers’ diarrhoea is the most common illness, rehydration is very important
Diseases such as Hepatitis B and HIV infection can be serious and can be transmitted by medical procedures, using unsterilized equipment, inadequately screened blood transfusions, unprotected sexual contact, tattoos and body piercing.
Mosquitoes, flies, ticks and bugs can cause many different diseases eg malaria, dengue fever and yellow fever Avoid being bitten by: applying insect repellents on exposed skin eg. 50% DEET, spray your clothes with repellents. If your room is not air conditioned, but
screened, close shutters before dusk and spray your room with insecticide spray. In malarious areas if camping or sleeping in unprotected accommodation, always sleep under a mosquito net impregnated with permethrin. Avoid camping near areas of stagnant water, which are common breeding ground for mosquitoes. Electric
insecticide vaporizers are effective. Electric buzzers, garlic and vitamin B12, yeast extract etc are ineffective for bite prevention.
This is one of the most serious diseases travellers will be exposed to when visiting a tropical country. Malaria is an infection from a parasite, which occurs when an infected mosquito bites you. There are four different types and the most serious is Plasmodium Falciparum, which can kill you in some circumstances within 24 hours of developing the symptoms of malaria. It is essential you prevent malaria by:
A - Awareness – being aware of whether malaria is present at your destination and how severe the risk is
B - Bite prevention – taking all precautions to minimize your chances of getting bitten
C - Chemoprophylaxis – making sure you take the correct tablets and complete the course
D - Diagnosis and prompt treatment – knowing that malaria presents like a flu like illness, sometimes with a cough and diarrhoea. If you get these symptoms especially in the first three months after you return but up to a year after your trip, you must seek urgent medical advice, and tell them you have been abroad.
Sunburn and heat stroke cause serious problems in travellers
