Other things that should be observed are general cleanliness of restaurant or food preparation area. A restaurant with no electricity, meat covered in flies hanging on hooks and perhaps a few stray animals wandering around is hardly likely to be a good risk!
There are also risks that can be avoided much more easily. These include casual sexual contact, intravenous drug use and other skin piercing activities such as tattooing and ear-piercing.
It is also important that you mention to your doctor that you have been travelling overseas to developed countries if you develop any symptoms such as nausea, lethargy, fever or jaundice after your return. These can often be categorised as a flu or common virus, when in fact they may be symptoms of a hepatitis infection. With full travel details, doctor will be more able to make a correct diagnosis and suggest necessary further testing.
With almost all health issues, key to disease free overseas travel is common sense. If you are going to be visiting a developing area, take time to ensure you receive necessary vaccinations in plenty of time for your trip. After all, that small amount of forethought may prevent a great deal of trouble later on. Copyright Felicity Walker 2005
