Why pre-travel health matters
Modern international travel exposes you to infectious diseases, environmental hazards, and medical situations not encountered in everyday life in Singapore. A 30-minute pre-travel consultation can prevent illnesses that would otherwise turn a planned trip into a hospitalisation - or worse.
The benefits scale with the type of trip:
- Routine business travel to developed countries: modest but real (vaccine boosters, basic kit)
- Holiday travel to popular destinations: moderate (food and water precautions, basic vaccines, traveller's diarrhoea kit)
- Adventure travel, remote destinations, long stays, immunocompromised travellers: substantial (multiple vaccines, malaria prophylaxis, evacuation insurance, detailed medical kit)
When should I see a travel doctor?
Ideally 4-6 weeks before departure. This allows:
- Multiple-dose vaccines (rabies pre-exposure: 3 doses over a month; Japanese encephalitis: 2 doses 28 days apart; hepatitis B: ideally 3 doses but accelerated schedules exist)
- Yellow fever vaccine, where required, needs at least 10 days to develop protective immunity before the International Certificate of Vaccination or Prophylaxis becomes valid 1
- Time to obtain less commonly stocked vaccines if needed
- Time to discuss and adjust if reactions or contraindications arise
That said, last-minute consultations are still very useful. Many vaccines work with a single dose, accelerated schedules exist for several others, and travel kit and prophylaxis advice can be provided same-day.
What does a travel consultation cover?
- Itinerary review. Destinations, duration, urban vs rural, type of accommodation, planned activities (adventure, sex tourism, healthcare exposure, animal contact, water sports). Destination-specific vaccination requirements are checked against current guidance before your visit 2.
- Personal medical history. Existing conditions, medications, immune status, prior vaccinations, allergies.
- Destination-specific risks. Infectious diseases endemic in your destination, environmental hazards, healthcare quality, security considerations.
- Vaccinations - current routine immunisations, plus travel-specific vaccines indicated for your itinerary.
- Malaria prophylaxis if travelling to malarial regions.
- Traveller's diarrhoea kit including oral rehydration salts, anti-motility medication, and standby antibiotic where appropriate.
- Other prescriptions as needed: altitude sickness prevention, seasickness, motion sickness, sleeping aids for long flights.
- General advice on food and water safety, insect bite prevention, sun protection, sexual health while travelling, healthcare access.
- Documentation - international vaccination certificates where required.
Common travel vaccinations available at Hisential
- Routine boosters - tetanus-diphtheria, MMR, polio, varicella
- Hepatitis A - recommended for most international travel
- Hepatitis B - for longer trips, healthcare exposure, sexual contact, tattooing/piercing
- Typhoid - for many tropical and developing-country destinations
- Japanese encephalitis - for rural Asia travel, particularly during transmission seasons
- Rabies (pre-exposure) - for adventure travel, animal contact, remote areas
- Meningococcal (ACWY) - for Hajj/Umrah pilgrimage and certain other destinations
- Cholera - for selected high-risk destinations
- Influenza - recommended seasonally and for most travel
Malaria prophylaxis
Several options are available, each with different dosing schedules, side effect profiles, and contraindications:
- Atovaquone-proguanil: Daily dosing; well-tolerated; suitable for short trips and last-minute travel
- Doxycycline: Daily dosing; sun sensitivity caution; not for pregnancy or young children
- Mefloquine: Weekly dosing; suitable for longer trips; specific psychiatric and cardiac contraindications
Your doctor will recommend the right option based on destination, duration, and your individual factors.
Beyond medication, bite prevention is equally important: DEET-containing repellents, long sleeves at dusk, permethrin-treated clothing for adventure travel, mosquito nets where indoor protection is uncertain.
Traveller's diarrhoea
Common - particularly in South Asia, parts of Africa, and parts of Latin America. Hisential's standard advice and self-treatment kit:
- Prevention: Bottled or boiled water; avoiding ice; cooked foods served hot; peelable fruit; reputable establishments
- Oral rehydration salts for any episode
- Loperamide (anti-motility) for short-term symptom control
- Standby antibiotic (typically azithromycin) for moderate-to-severe cases, with clear instructions on when to use
Special situations
Altitude travel (Andes, Himalayas, parts of Africa): acetazolamide for altitude sickness prevention; advice on gradual ascent and recognising serious altitude illness.
Pregnancy and travel: specific considerations including which vaccines are safe, malaria prophylaxis options, Zika-affected destinations to avoid, travel timing.
Long-haul flight DVT considerations for higher-risk individuals.
Pilgrimage travel (Hajj/Umrah): meningococcal ACWY vaccine (mandatory for entry), influenza, food safety, heat illness prevention.
Sexual health while travelling: practical advice; emergency contraception; access to PEP if needed during travel; access to STI testing on return - see STD testing and HIV testing.
Post-travel: what if I'm sick after returning?
Several illnesses can present weeks to months after travel. Seek medical assessment promptly for:
- Fever after travel to malaria-endemic areas - this is an emergency until malaria is excluded
- Persistent diarrhoea beyond 2 weeks
- Unusual rashes following travel
- Jaundice - yellowing of skin or eyes
- Persistent cough beyond 3 weeks
- Genitourinary symptoms after sexual contact during travel
Hisential provides post-travel medical assessment for any returning traveller with concerns.
How much does travel health cost in Singapore?
- Vaccinations: Per-dose pricing varies by vaccine; common vaccines discussed transparently
- Malaria prophylaxis prescription: Quoted at consultation
- Traveller's diarrhoea kit: Quoted at consultation
Total cost depends on what your specific trip requires and is communicated openly.
Patient pathway and follow-up
A complete clinical episode at Hisential is structured around four clearly-defined stages, so patients understand what to expect at each visit and how decisions are made.
Stage 1 - Pre-consultation triage
Before your first appointment for travel health and vaccination, our care coordinators take a brief history by WhatsApp or phone to determine whether teleconsultation, an in-clinic visit, or a same-day workup is most appropriate. This avoids unnecessary travel for issues that can be triaged remotely, and ensures patients with urgent presentations are prioritised. Where laboratory tests, imaging, or fasting are likely to be needed, we explain the requirements in advance so the first visit is productive rather than purely exploratory.
Stage 2 - In-clinic assessment
The first consultation includes a structured medical history, focused examination, and - where clinically indicated - point-of-care or laboratory investigations. Doctors document findings in our digital records system and walk patients through the rationale for each test. Costs are confirmed before any chargeable investigation is performed; nothing is added without consent.
Stage 3 - Diagnosis, plan, and shared decision-making
Once results are available, the doctor reviews them with the patient in plain language, including normal ranges, areas of concern, and the level of evidence behind any proposed intervention. For travel health and vaccination, treatment options are framed in terms of expected benefit, realistic timelines, side-effect profile, and cost. Patients are encouraged to ask questions and may request a second appointment to consider their options before starting treatment - there is no pressure to decide on the day.
Stage 4 - Follow-up and continuity
Follow-up intervals are agreed at the end of the first visit and depend on the condition: chronic management is typically reviewed every 3-6 months, while acute episodes may be reviewed within 1-4 weeks. Teleconsultation (from S$50 after GST) is offered for routine follow-ups where physical examination is not required. Records are retained securely and remain accessible to the patient on request, including for onward referral or coordination with another doctor.
What we will not do
Hisential does not sell unproven therapies, does not recommend tests without a clinical indication, and does not extend treatment courses beyond what the evidence supports. If a condition falls outside our scope - for example, requiring inpatient care, surgical sub-specialty input, or oncology services - we say so and refer appropriately. Honest scope is part of the standard.
