How to Avoid Jet Lag

Jet lag occurs when we travel through several time zones which interrupt the normal body clock and causes disturbed sleep patterns and disorientation. When you fly East to West jet lag is worse as the body finds it hard to adapt to shorter days than longer ones.

Symptoms tend to only last a couple of days until your body has acclimatised to the new time zone and include:

• Sleep disturbance - the most common symptom
• Nausea or indigestion
• Altered bowel habits :constipation and diarrhoea
• Anxiety
• Irritability
• Clumsiness
• Memory problems
• Lack of energy
• Headaches
• Generally feeling unwell

How to avoid Jet Lag

• Before you travel make sure you feel rested and try to prepare your body for the new time zone. Go to bed slightly earlier if you are travelling east and going to bed later if flying west.
• When you board your flight adjust your watch to the time of your destination. If you are arriving in the evening, try not to sleep too much during the flight so that when you are you will be able to go to bed at your destinations night fall. If your flight arrives in the morning, try and sleep as much as you can during the flight, so you can stay awake during the day. Sleeping on a flight can often be difficult, use ear plugs and eye shades to help you sleep.
• Include a stopover on the way if possible. A stopover will make it easier for you to adjust to the time zone at your final destination.
• Avoid caffeine and alcohol during the flight as these can disturb sleep. Make sure you stay well hydrated as dehydration can intensify the symptoms of jet lag.
• Taking sleeping tablets are not recommended; as it does not help your body adjust to normal sleeping patterns.
• Try to get into the local routine as soon as you arrive. Spending time in natural light helps the body adjust quicker.
• Try to get the normal amount of sleep you would in every 24 hours. Try and have a minimum block of four hours sleep, known as 'anchor sleep' this helps you adjust to the new time zone. Try and make up the rest of your normal sleep hours by taking naps during the day.
• If you trip is short (3 to 4 days or less) if possible it may be better to stay on home time as this will minimise sleep disturbance on your return.

Disease Focus - Typhoid

Typhoid fever is a disease spread through ingestion of food and water contaminated with faeces or urine from a human carrier. It is caused by gram negative bacteria, Salmonella enterica serotype typhi.

Open sewer Thailand

Signs and Symptoms

It has an incubation period of 1 - 3 weeks. Symptoms range from mild to severe and include:
Mild cases: fever, constipation or diarrhoea abdominal pain, loss of appetite, headache, myalgia and a rash can develop.
Severe cases: disseminated disease with multi organ involvement and meningitis can occur.
10-15% of all cases develop complications which can include intestinal perforation, pneumonia, fits and meningitis. With prompt antibiotic treatment case fatality is less than 1%, but can be as high as 20% in untreated cases. 1-3% of people become long term carriers after infection with typhoid fever. [1]. 


Risk for Travellers

Typhoid fever can be found worldwide, but it is predominately in countries where hygiene standards are poor. The highest risk areas are the Indian subcontinent, Asia, Africa and Latin America. 16 to 33 million cases of typhoid occur each year according to the World Health Organisation (WHO) with approximately 500,000 to 600, 000 deaths.
The risk of contracting typhoid fever depends on the country visited, the highest risk remains in travellers visiting the Indian subcontinent with 17.3 cases per 100,000 travellers reported. Risk in high income countries remains low with less than 1 case per million visits [2]. 


Prevention

If you are travelling to a high risk destination where sanitation and food hygiene is poor you should consider getting a typhoid vaccination. For country recommendations visit Fit For Travel.

Food and water hygiene is equally important. You should:

• Only drink and clean teeth with bottled or boiled water
• Avoid  foods such as shellfish that may have come from contaminated water
• Avoid salads that may have been washed in contaminated water
• Avoid ice in drinks , unless you are sure it has been made with clean water
• Wash hands regularly or use an alcohol hand gel when washing facilities are not available

Staying safe when abroad- FCO report highlights problems Brits can encounter abroad

As a travel health nurse advisor, I tend to focus on health issues such as malaria and vaccine preventable diseases during my consultations with travellers. However, it is not just health risks that can ruin a trip abroad. Last year the Foreign Office (FCO) assisted 5700 cases of arrest abroad, a 10% drop on the year before, but despite the positive trend the report highlights that many travellers are not aware of the risks and troubles they can encounter.

Key Findings 2010/11

• 25,969 Britain’s needed assistance for lost or stolen passports
• Though down by 20%, a total of 799 drug arrests were reported
• Countries with the majority of drug arrests include: Jamaica, Argentina, Brazil, Serbia and Peru
• The highest number of arrests took place in Spain
• 347 deaths were reported in Thailand- 60% died of natural causes
• The highest number of rapes occurred in Egypt, followed by Turkey.Cases of reported rapes has almost halved in Greece since 2009/10

How the FCO can help you abroad

If you do find yourself in trouble abroad the FCO can help you with the following:

• Issue emergency travel documents, such as a lost passport
• Give you details of local lawyers, funeral directors, doctors and interpreters
• Contact your friends and family back home
• Visit you in hospital if you have been arrested
• Provide you with information about transferring money

They cannot help with the following:

• Give legal advice
• Help with entry to a country without a passport or necessary visa's
• Financial help- paying bills or giving you money
• Making travel arrangements for you
• Get you better medical help in hospital than is given to local people

Tips for staying safe abroad

• Ensure you have adequate travel insurance, declare pre-existing medical conditions to your insurer and read the small print
• Study the local laws and customs of the country you are visiting
• Make sure you have enough cash to cover any emergency situations
• Check your passport is in date and you have any required visa's
• Make copies of any documents and store securely online.
• Tell someone where you are going and leave emergency contact details with them
• If you are sexually assaulted abroad, inform the local police and contact the Foreign Office who can offer you support
• Get the necessary travel vaccinations and malaria tablets before you travel
• Understand the risks you are taking if you get involved with illegal drugs. Many countries carry harsh sentences, including the death penalty in some countries.
• If you are visiting countries in the European Economic area, apply for a EHIC card online or by phone 0845 605 0707

Disease Focus - Hepatitis A

Hepatitis A is an infection of the liver and cases occur worldwide, although it is less common in Europe, North America, Australia and New Zealand. It is endemic in many low income countries. Around 1.5 million cases of hepatitis a occur each year.[1] It is spread through the faceal oral route, person to person spread or through eating and drinking contaminated food and water.Those working with human waste and sewage are also at occupational risk.

Signs and Symptoms

It has an incubation period of 2 - 6 weeks, but less than 10% of those infected develop symptomatic illness. Likelihood of symptomatic illness increases with age.Symptoms include mild fever, diarrhoea, nausea/vomiting and abdominal pain. Jaundice may follow and lasts up to 10 days. Recovery takes several weeks, but some patients are ill for longer. Complications can occur in those with pre - existing medical conditions or liver disease.There is no specific treatment for hepatitis a. Following infection  life long immunity occurs.

Risk for Travellers

Risk of contracting hepatitis a in high income countries is low. Non- immune travellers are at risk of contracting the disease when visiting countries where risk of infection is high. The risk of acquiring hepatitis A in high-income countries is low.  Non-immune travellers are at risk of contracting the disease during visits to countries of high or intermediate endemicity. Travellers to Africa, South East Asia, the Indian sub Continent and Latin America are at higher risk.In 2009, a total of 352 cases were reported in the UK, 61% of these where associated with travel. [2]. Although the incidence of hepatitis a infection amongst travellers is declining, it remains one of the most common vaccine preventable diseases amongst travellers. Risk is higher for those visiting friends and relatives abroad, long term travellers and those visiting countries where sanitation is poor.However, there have been cases occur in tourists staying in good quality accommodation. Many travellers think staying in a 5 star hotel puts them at lower risk, but because it can be transmitted person to person, staying in luxury accommodation in a high risk country still remains a risk.

Prevention

A every effective vaccine is available to prevent infection with hepatitis a. Two doses are required to offer long term protection ( up to 30 years) One dose will offer protection for up to 1 year, the booster dose should be given 6 - 12 months after the first dose. Ideally you should have the vaccine at least 14 days before travel, but because hepatitis a has a long incubation period it can be given at the last minute and still offer good protection. The vaccine can be given to travellers aged 1 year and over.Contraindications to having the vaccine include: acute febrile illness, previous reaction to hepatitis a vaccine and egg allergy for those receiving the brand Epaxal vaccine. Side effects to the vaccine are usually mild but can include pain and redness at the injection site, less common are mild fever, tiredness, headaches and dizziness.

Food and water hygiene is equally important. You should:

• Drink and clean teeth with bottled or boiled water
• Avoid shellfish that may have come from contaminated water
• Avoid salads that may have been washed in contaminated water
• Avoid ice in drinks , unless you are sure it has been made with clean water
• Wash hands regularly or use an alcohol hand gel when washing facilities are not available
