Polio — booster recommended; exit requirement applies
Pakistan is one of only two countries with endemic wild poliovirus (WPV1) transmission. Travelers should be fully immunized per the Swiss BAG schedule; adults who completed their childhood series should receive a one-time IPV booster before travel. Pakistan also imposes an EXIT requirement: travelers leaving the country after a stay of four weeks or more must show proof of polio vaccination received between 4 weeks and 12 months before departure, documented in an International Certificate of Vaccination (ICVP). Plan timing with your travel medicine specialist.

There is no yellow fever risk in Pakistan. A YF vaccination certificate is required only for travelers aged 1 year and older arriving from a country with risk of YF transmission. Direct travel from Switzerland is not affected.

Disease-specific guidance
Malaria
ModerateChloroquine-resistant malaria is present in all areas, including all cities, below about 2,500 m elevation. Chemoprophylaxis is recommended for travel to risk areas; areas above 2,500 m (high-mountain regions) are risk-free. P. vivax predominates, with P. falciparum also present.
- Risk
- All areas incl. cities below ~2,500 m
- No risk
- Above ~2,500 m (high-mountain regions)
- Species
- Mostly P. vivax; ~20% P. falciparum (chloroquine-resistant)
- Prevention
- Chemoprophylaxis recommended for risk areas
Yellow fever
NoneNo yellow fever risk in Pakistan. A YF certificate is required only for travelers aged 1 year and older arriving from a country with risk of YF transmission. Direct travel from Switzerland is not affected.
Dengue
HighEndemic with large seasonal outbreaks in major cities including Karachi, Lahore, and Rawalpindi/Islamabad; risk peaks during and after the monsoon (roughly August–November). Daytime mosquito-bite prevention is the main protection.
- Distribution
- Major cities: Karachi, Lahore, Rawalpindi/Islamabad
- Season
- Peaks August–November (post-monsoon)
- Mosquito
- Aedes aegypti — bites during daytime
Chikungunya
ModerateTransmission occurs with periodic outbreaks, including in southern urban centers. Same daytime Aedes mosquito vector as dengue, so dengue prevention also protects against chikungunya. Vaccination considered for extended stays in elevated-risk areas or outbreak settings (see EKRM statement).
General prevention
Food & water
Traveler's diarrhea, typhoid, and hepatitis A are common. Use bottled or properly treated water, avoid ice from unverified sources, and stick to thoroughly cooked food and fruit you peel yourself. An extensively drug-resistant (XDR) typhoid strain circulates, so food/water hygiene and typhoid vaccination are especially important.
Mosquito protection
Dengue causes large urban outbreaks (Karachi, Lahore, Rawalpindi/Islamabad), so daytime mosquito protection (DEET or picaridin repellent, long sleeves) is essential. Malaria is present in all areas below ~2,500 m including cities, requiring dawn/dusk and overnight protection; in rural areas also protect against Japanese encephalitis. Tick precautions reduce risk of Crimean-Congo hemorrhagic fever.
