What is Hepatitis B?
Hepatitis B is a viral disease that attacks the liver. If you contract the virus as an adult it will probably disappear on its own if it is acute, but it can lead to chronic Hepatitis B. If this happens it can develop into cirrhosis or liver cancer and be fatal.
What Are The Symptoms?
Some people who contract acute Hepatitis B may not develop any symptoms. Others may notice a yellowing of the skin and eyes (jaundice), dark urine, extreme tiredness, nausea, sickness and stomach pains.
How Is It Contracted?
The Hepatitis B virus is transmitted via blood and other bodily fluids, including saliva, menstrual, vaginal, and seminal fluids. It can be passed from mother to child at birth, and the risk of an infant developing chronic Hepatitis B is very high. Sexual transmission is also possible and drug users can contract it by sharing infected needles.
I am most familiar with Thailand and visitors should be careful if engaging in sexual activity with commercial sex workers, of which there are many.
Hygiene standards in Thai hospitals and dental surgeries tend to be quite high so I would imagine that the risk of contracting Hepatitis B through surgical instruments is quite low, however, many foreigners visiting Thailand like to have tattoos done and hygiene standards in some of Thailand's tattoo parlours may not be so stringent.
Who Is At Most Risk?
Hepatitis B is only dangerous if the acute version develops into a chronic version. This is fairly rare among adults (about 5%), but high with infants (80% to 90%) and young children (30% to 50%).
Where Are You At Risk?
Hepatitis B occurs worldwide, but with a higher risk in certain parts of Asia, Africa and South America. Vaccination programmes seem to have been very effective in lowering the risk of contractions.
In Western countries vaccination is normally carried out at birth. The vaccine will last for at least 20 years and probably for your lifetime. The Orld Health Organisation does not recommend booster jabs.
If you were vaccinated at birth, don't worry. If you weren't and you are considering visiting a country where there is a risk of contracting Hepatitis B you should consult your physician.
When Should You Be Vaccinated?
This is normally done shortly after birth.
Does The Vaccine Have Any Side Effects?
Like most injections, some people may experience tenderness and redness at the site of the injection. Children may become irritable and develop cold-like symptoms.

Thailand is an incredibly photogenic country, both for its landscapes and its people. Regardless of whether you enjoy large Asian cities, beaches and islands, or rice fields and mountains, Thailand has something for you and it is a dream destination for photographers.
One of the great things about visiting Thailand is that hotels are plentiful and a lot cheaper than in most other countries. Each link on the right will take you to the relevant page on the Agoda website where you can see photos, read reviews, and book on-line. I use Agoda to book all of my own hotels in Thailand and the Southeast Asia region. Agoda hotel rates are usually always the lowest and I have received good customer service, therefore I am happy to recommend the company to other people. Here is some analysis I did regarding booking hotels in Southeast Asia.
Booking.com used to be more expensive than Agoda, but when I have checked hotel prices recently I have found their rates to be quite competitive. Unlike Agoda, you don't need to pay at the time of booking with Booking.com - you can simply pay at the hotel when you check in. Also, Booking.com show you total prices whereas Agoda show you a price and then add on 17% for tax and service charge.
If you wish to compare prices between different on-line travel agents (OTAs) for a specific hotel, you can use a company such as HotelsCombined.
