Travel Health: Vaccines, Malaria & Staying Healthy Abroad

Good travel health preparation takes 6–8 weeks before departure. The right vaccines, antimalarials, and hygiene habits make international travel safe and enjoyable.

Malaria Prophylaxis

DrugRegionDosingKey Notes
Atovaquone/proguanil (Malarone)Most areasDaily; start 1–2 days before; stop 7 days afterBest for short trips; few side effects
DoxycyclineSoutheast Asia, AfricaDaily; start 2 days before; stop 4 weeks afterCheapest; photosensitivity; avoid in pregnancy
Mefloquine (Lariam)Selected areasWeekly; start 2–3 weeks beforePsychiatric side effects — avoid if history of depression/epilepsy
Chloroquine + proguanilLimited areas now (mainly Caribbean)Daily; start 1 week beforeChloroquine resistance widespread — limited use
Bite Avoidance Is as Important as AntimalarialsDEET 50% repellent, long-sleeved clothing, permethrin-treated clothing, and insecticide-impregnated bed nets reduce malaria transmission independently of antimalarial medication. No prophylaxis is 100% effective.
How early should I see a travel health nurse?
Ideally 6–8 weeks before departure. Some vaccines (hepatitis B, rabies) require multiple doses over weeks. Yellow fever is given by certified centres. Some areas have rapidly changing risk profiles.
Does the EHIC/GHIC cover all healthcare abroad?
No. The GHIC (UK replacement for EHIC) provides access to state healthcare in EU countries at the same cost as locals — not private hospitals, not repatriation, not pre-existing condition cover. Travel insurance with adequate medical cover is essential.
What is traveller's diarrhoea?
The most common travel illness — bacterial gastroenteritis (usually E. coli) from contaminated food or water. Prevent with food hygiene (boil it, cook it, peel it, or forget it). Treat with oral rehydration; antibiotics (azithromycin or ciprofloxacin) for moderate-severe cases.
Can pregnant women travel abroad?
Generally yes, with precautions. Avoid malaria-endemic areas if possible (antimalarials have varying safety profiles in pregnancy). Yellow fever vaccine is contraindicated in pregnancy. Long-haul flights: low-dose aspirin + compression stockings for DVT prevention. Most airlines won't carry women past 36 weeks.
