Here are some frequently asked questions (FAQs) and top 5 things to consider as you prepare for your next trip abroad !

Pre-Travel Travel Vaccinations

1. Where are you going ?

It is advisable to check with your doctor the necessary vaccinations and medications you should be getting to protect yourself before the trip.

Furthermore you can visit for more country specific information. If we have been there before, we might even exchange tips on best places to visit or things to try! Tag: travel vaccinations

2. Purpose of travel and activities at destination

Routine vaccinations are those that you would have already received through your country’s immunization programme. Travel vaccines are usually not part of the schedule of vaccinations you would have received in the programme.

There is also a window to take note for the effectiveness of these vaccinations. Unfortunately, exceeding the duration would require a reimmunization.

Doses Years
Yellow Fever 1 10 Years
Typhoid 1 3 Years
Rabies 3 5 Years
Polio 1 10 Years
Tetanus 1 10 Years
Influenza 1 1 Year

If in doubt, there are confirmatory tests which can also be done to check for certain immunities, mainly –  MMR, Varicella, Hepatitis A, Hepatitis B.

Malaria is a mosquito-borne disease caused by a parasite. It is transmitted through the bite of an Anopheles mosquito. In the body, these parasites replicate in the liver, and subsequently infect the red blood cells of the body.

Symptoms occur 1-2 weeks after the initial bite and may present with persistent fever, flu-like illness, stomach discomfort (bloating, nausea, diarrhoea, bloody stool), headache. As the infection persists, symptoms occur in cycles that last two to three days each time. There may also be a late presentation of symptoms several months after leaving an endemic area.

Left untreated, Malaria may cause life threatening complications.

Risk varies from place to place and also within a country. Your doctor will often check with the latest updates from CDC (communicable disease center) and discuss with you further, your options.

Protection from Mosquito-borne Diseases:

  • Wear light-coloured, long sleeve clothings especially at night.
  • Use insect repellent on exposed skin.
  • Sleep under a mosquito net.
  • Light a mosquito coil before going to bed.
  • malaria prophylaxis.

These are some of the commonly used malaria prophylaxis medications.

Rabies is a disease that spreads from animals to humans. The mode of transmission is usually through the saliva after a bite from an infected animal.

The initial symptoms always mimick a flu-like illness but subsequently, patients with rabies develop the following symptoms

  • Agitation, Anxiety, Confusion
  • Hyperactivity
  • Difficulty swallowing, Excessive salivation
  • Fear of water (hydrophobia) because of the difficulty in swallowing
  • Hallucinations, Insomnia
  • Partial paralysis

Travellers to rabies-affected areas according to the level of risk in that area may also receive prophylactic vaccination. Since 2018, this is 2 separate vaccinations at day 0 and 7 and for those who are immunocompromised, a third vaccination at 21 or 28 days after the initial vaccination.

If however you suspect the bite of an animal which may have rabies, you may contact the TTSH traveler’s clinic within 7 days for Post Rabies Exposure treatment.

At 2,500 metres (8,000 ft), the changes in altitude result in some people developing acute mountain sickness.

The symptoms include headache, lethargy and light-headedness, stomach symptoms (poor appetite, nausea, vomiting) and difficulty sleeping.

Some tips to overcome this would include ascending gradually if possible, staying hydrated, minimizing physically demanding activity and last but not least, inquiring with our team for Altitude Sickness medications such as Diamox (Acetazolamide).

Adult circumcision
  • Flights can be quite a dehydrating affair to the body. It is always advisable to eat light, drink lots of fluids and avoid alcohol.
  • To prevent blood clots from forming in your leg (which can be nasty), exercise your leg muscles with regular stretches and take regular walks around the cabin every few hours if possible.
  • Lastly try to get as much rest and sleep as possible. It will help your body recover faster from the effects of traveling
  • To minimise the effects of jet lag, eat and sleep according to the local time at your destination as soon as you can. There are over the counter medications (melatonin) and prescription medications which you can take to aid you in your sleep as well if you have difficulty sleeping or adjusting jet lag.
  • At your destination, food and water precautions should be observed.

– Check that food is well cooked.
– Avoid undercooked food, salads and fruits.

– Eat food that is hot when served.
– Use a serving spoon when eating from a common plate.

– Avoid tap water and ice cubes.
– Drink only bottled water or boiled water
