Major Infectious Diseases to Watch During UAE Travel
Mosquito-Borne Infections
In UAE's humid coastal regions, mosquito-borne infectious diseases are present.
| Infection | Vector Mosquito | Risk Areas | Characteristic Symptoms |
|---|---|---|---|
| Dengue fever | Asian tiger mosquito | Dubai, Abu Dhabi coast | Fever, joint pain, rash |
| Chikungunya fever | Asian tiger mosquito | Humid districts | High fever, prolonged joint pain |
| West Nile virus | Common house mosquito | Inland areas | Mild to severe neurological symptoms |
Prevention measures:
- Use mosquito repellent (containing 20-30% DEET): Insect Ecran® or Repel® are commonly available
- Wear long sleeves and pants (during early morning and evening activities)
- Verify mosquito netting at accommodation
- Check window screens
Pharmacist's note: Higher DEET concentrations provide longer protection, but 20-30% DEET offers sufficient effectiveness while balancing skin irritation concerns. Reapplication every 6 hours is recommended. For facial application, first spread on your hands, then apply—this two-step method enhances safety.
Intestinal Infections and Foodborne Illness
While UAE maintains relatively high hygiene standards among Middle Eastern countries, traveler's diarrhea remains a risk.
Common causative pathogens:
- Enterotoxigenic Escherichia coli (ETEC)
- Campylobacter
- Salmonella
- Cryptosporidium
Medications for symptom management:
| Medication | Active Ingredient | Purpose | Dosage |
|---|---|---|---|
| Loperamide | Loperamide | Antidiarrheal | 2 mg per episode, max 8 mg daily |
| Bismuth subsalicylate | Bismuth compounds | Diarrhea and indigestion | 2-4 tablets per dose, 3-4 times daily |
| Azulene-sulpyrine combination | Sodium azulene sulfonate | Intestinal inflammation relief | 1-2 packets per dose, 3 times daily |
Pharmacist's note: While loperamide effectively relieves symptoms, it should be avoided in bacterial enteritis. If high fever or bloody stools are present, seek medical attention first. Bismuth preparations may cause blackening of the tongue or stool, but this is harmless.
Respiratory Infections
Respiratory infections increase during UAE's winter months (November–March).
- Influenza (particularly Type A)
- COVID-19
- Common cold viruses
Recommended vaccinations:
- Influenza vaccine: recommended 2 weeks before travel
- COVID-19 vaccine: confirm based on current circumstances
- Pneumococcal vaccine (for ages 65+, or with underlying conditions)
Water and Food Safety in UAE
Water Quality
UAE's tap water is strictly regulated and generally safe for consumption. However, older buildings may have pipe contamination issues.
Recommendations:
- Accommodation tap water: generally safe to drink
- Ice at street stalls: best avoided
- Bottled water: domestic brands such as Al Ain® and Masafi® are reliable
- Coffee and tea: safe due to heat treatment during preparation
Food Selection Guide
| Food Category | Safety | Notes |
|---|---|---|
| Hotel and upscale restaurant meals | ★★★★★ | Strict hygiene standards |
| Large mall food courts | ★★★★☆ | Relatively safe, but verify compared to street vendors |
| Street stalls and street food | ★★☆☆☆ | Avoid raw vegetables and cold preparations |
| Raw vegetables and fresh fruit | ★★★☆☆ | Choose cooked or peeled varieties |
| Dairy products | ★★★★☆ | Most are pasteurized |
Pharmacist's note: For regional specialties like phoenix dates and hummus (chickpea paste), choose establishments with verified sanitation practices. When purchasing from street vendors, relatively safer options include stalls where food preparation is visible and where high customer turnover indicates rapid food rotation.
UAE Climate and Medication & Hygiene Measures
Climate Characteristics
UAE climate (particularly Dubai and Abu Dhabi):
- Summer (May–September): temperatures exceed 45°C, humidity 50-80%
- Winter (November–March): temperatures 20-30°C, humidity 30-60%
Summer Medications and Measures
Heat exhaustion and dehydration prevention:
- Oral rehydration solutions: Pocari Sweat®, Aqua Light ORS® (purchase before arrival recommended)

Skin trouble management:
| Problem | Cause | Treatment Medication | Prevention |

Pharmacist's note: UAE summer midday temperatures are extreme; avoid outdoor activities between noon and 3 PM. For heat illness preparedness, locate the nearest private hospital via GPS and confirm location before travel.
Winter Medications and Measures
Respiratory dryness prevention:
- Use a humidifier (if not provided by hotel)
- Nasal saline spray: Saline Rinse®
- Throat lozenges: propolis-containing or peppermint varieties
Adjustment to temperature fluctuations:
- Outdoor temperature (20-30°C) contrasts sharply with heavily air-conditioned indoor spaces (below 18°C)
- Keep lightweight layers handy
- Cold and flu medication: Benza Block®, Contac®
Medication Import Guidelines for UAE Travel
Prescription Medications
UAE maintains strict pharmaceutical import regulations.
Required procedures:
- Carry English-language physician's certificate
- Keep copy of prescription
- Transport medications in original containers (do not repackage into small bags)
- Declare at customs upon entry
Important note: Psychoactive medications (sedatives, antidepressants) may require pre-clearance. Verify latest requirements at the Embassy of Japan in the UAE.
