What is Yellow Fever?
Like Malaria, Dengue Fever and Japanese Encephalitis, Yellow Fever is a mosquito borne disease. The culprit in this case is the Aedes aegypti, which is also responsible for some other nasty diseases including Dengue Fever.
Whereas mosquitoes are normally active from dusk until dawn and bite when it is dark, these mosquitoes are active and bite during the daytime.
What Are The Symptoms?
As with many tropical diseases, symptoms are flu-like and include high fever, sweating, headaches, nausea, vomiting and diarrhoea. Sufferes can have muscle pain and experience sensitivity to bright light. In most cases the symptoms don't last long and the patient recovers rapidly.
However, with some people the infection can come back and if it causes liver damage this can result in yellow skin (jaundice), hence the name.
How Is It Contracted?
The disease is contracted after being bitten by a mosquito carrying the disease. Mosquitoes carry the disease after biting infected monkeys or people. Yellow fever cannot be contracted directly from person to person.
Who Is At Most Risk?
Unvaccinated people who visit parts of the world where there is a high risk of contracting Yellow Fever and those with weak immune systems.
Where Are You At Risk?
Yellow Fever is prevalent in Africa, South America, Central America and the Caribbean.
Thailand, where I live, is free of Yellow Fever, but all the conditions are right for it to be a big problem. The weather is hot and humid and there are lots of Aedes aegypti mosquitoes.
To prevent the introduction of Yellow Fever the Thai government rightly insists that visitors arriving from countries where the risk of Yellow Fever is high must have a certificate to prove they have been vaccinated against the disease. These include:
Angola, Benin, Bolivia, Brazil, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Colombia, Congo, Congo Republic, Cote d' Ivore, Ecuador, Equatorial Guinea, Ethiopia, French-Guiana, Gabon, Gambia, Ghana, Guinea-Bissau, Guinea, Guyana, Kenya, Liberia, Mali, Mauritania, Niger, Nigeria, Panama, Peru, Rwanda, Sao Tome & Principe, Senegal, Sierra Leone, Somalia, Sudan, Suriname, Tanzania, Togo, Trinidad and Tobago, Uganda, Venezuela, Argentina, Paraguay.
Before you travel to another country always check the visa requirements and ensure you have everything required to be allowed into the country.
A vaccine is available and provides lifelong protection. In the UK it isn't free and there is a charge. The vaccine must be administered at least 10 days before travel.
To be allowed to enter certain countries it is necessary to show a cerificate stating that you have been vacinated against Yellow Fever. This certificate is issued when you are given the vaccine.
When Should You Be Vaccinated?
At least 10 days before you travel.
Does The Vaccine Have Any Side Effects?
Like most injections, some people may experience tenderness and redness at the site of the injection. Some people may suffer from headaches, fever, nausea, stomach pains or diarrhoea. There may be a mild rash and some muscle/joint/body aches and pains.

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. I always use Agoda to book hotels in Thailand. The company was established in Thailand and has great local knowledge, as well as a huge inventory of hotels.
If you click on one of the destinations opposite you will get a list of hotel deals from Agoda. It's generally a good idea to book on-line because you will get a good room rate and you won't suffer the disappointment of arriving at a hotel to find that it is full.
I book hotels regularly in Thailand and I have always found Agoda to be the best on-line travel agent. At times I have spent a lot of time researching hotel prices and although other deals sometimes look better at first I always end up returning to Agoda.
If you don't wish to pay for your hotel at the time of booking, Booking.com normally allows you to pay when you check in at the hotel. Some people prefer this method, but I have always found Booking.com to be more expensive than Agoda.
If you want to compare prices between different on-line travel agents (OTAs) for a specific hotel, you can use a company such as HotelsCombined. However, you will normally find that Agoda is the cheapest and therefore you can save yourself time and money by just booking through Agoda in the first place.
