As far as crime goes, the UAE is a very safe region. The main danger is bad driving - many drivers don't seem to have a concept of other cars, and courtesy on the road simply does not exist. Although many of the beaches in the country look calm, they often have dangerous rips. If swimming at an unpatrolled beach (no public beaches are patrolled) be very careful. There are regular reports of people drowning, particularly at the beaches in Dubai.
Several different viruses cause hepatitis; they differ in the way that they are transmitted. The symptoms in all forms of the illness include fever, chills, headache, fatigue, feelings of weakness and aches and pains, followed by loss of appetite, nausea, vomiting, abdominal pain, dark urine, light-coloured faeces, jaundiced (yellow) skin and yellowing of the whites of the eyes.
There are 6 known types of viral hepatitis:A, B, C, D, E and G. G is not dangerous. A and E are passed on by the fecal-oral route of transmission; there is a vaccine. Seek medical advice, but there is not much you can do apart from resting, drinking lots of fluids, eating lightly and avoiding fatty foods. A and E cause an acute illness, but you will recover fully from it.
B and D are passed on via blood, saliva, semen and vaginal fluids. They can be passed on by close contact, sexual contact, and blood-to-blood contact. The symptoms of hepatitis B may be more severe than type A and the disease can lead to long-term problems such as chronic liver damage, liver cancer or a long-term carrier state. There is a vaccine.
Hepatitis C is only passed on from blood-to-blood contact. There is no vaccine.
