Polio

 

What is Polio?

Poliomyelitis (polio) is a highly contagious and infectious disease caused by the polio virus. This enters the body through the mouth and multiplies in the throat and intestines. The disease attacks the nervous system and can cause paralysis, which is almost always permanent. In the most severe cases, polio is fatal.

What Are The Symptoms?

Polio infections can produce symptoms with varying degrees of severity. The majority of individuals have no symptoms at all. However, some people may experience a number of symptoms including fever, headaches, vomiting, constipation, stiffness in the neck and pain in the limbs.

Of those who do contract polio, only a small percentage will develop the paralytic disease.

How Is It Contracted?

Transmission of the polio virus most often occurs through either person to person contact, or by faecal-oral contact - as a result of poor hand washing, from ingestion of contaminated food or water, and in environments where hygiene and sanitation are poor. Those infected with the virus can excrete the virus in their stools for several weeks and are most contagious 7 to 10 days before and after the onset of symptoms.

Where Are You At Risk?

Polio transmission has stopped in almost all industrialised countries, and remaining countries are expected to be free from polio by 2005. However, travellers are still at risk in the following areas:

  • Indian subcontinent
  • Egypt, Sudan, Somalia, Nigeria and Angola

Vaccination

Following several epidemics throughout the early to mid 20th century, there has been a worldwide effort to eliminate the virus. While the disease is now rare in the Western and Northern Hemispheres owing to vaccination, it remains common in some parts of the world. Vaccination is available through your doctor's surgery.

When Should You Be Vaccinated?

Polio vaccination is usually given as a live oral vaccine, which is deposited directly onto the tongue. In he past, administering it with a sugar lump masked the bitter taste of the vaccine. This practice has fallen out of favour owing to the risk of tooth decay.

Infants should be vaccinated with a series of doses at an early age, and then boosters given before starting and leaving school. Individuals born before 1958 may not have been vaccinated as part of the childhood immunisation programme, and should check whether they need to complete a polio vaccination programme as adults. Anyone considering travel to an area where the disease is more common should consult his or her practice nurse or doctor for polio vaccination advice.

If you have never been vaccinated against polio, you can have your first dose at any time, followed by two or more doses at intervals of four weeks. Although a booster dose is not routinely necessary for adults, it is advisable for those exposed to continuing risk - travellers to high risk areas and healthcare workers exposed to the polio virus - to have a single booster dose every 10 years.

Check with your practice nurse as soon as you have decided where and when you are travelling, and they will advise on an appropriate vaccination schedule for you.

Visit Thailand

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 tend to use Agoda to book all of my own hotels in Thailand and the Southeast Asia region. I generally find Agoda hotel rates to be the lowest and I have received good customer service, therefore I am happy to recommend the company to other people.

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.
