Tajikistan is malaria-free. Ticks and sand flies are the bites to plan for.
- No CDC travel notice for mosquito-borne disease
The World Health Organization certified Tajikistan malaria-free in 2023, and CDC lists no dengue, chikungunya or Zika. On a June–September trek, mosquitoes aren't a reported problem. Ticks in the southern lowlands and night-biting sand flies in some village homestays are what to plan for.
Are there mosquitoes in Tajikistan? Some, near rivers and lakes, and none that carries a disease of concern. The World Health Organization certified Tajikistan malaria-free in 2023, and CDC lists no dengue, chikungunya or Zika. On a summer trip to the Pamir Highway or the Fann Mountains, the bites that deserve a routine are ticks in the south and sand flies in some villages at night.
Malaria-free since 2023
Malaria had been eliminated by the early 1960s, then returned in a 1990s epidemic of more than 400,000 cases before control was restored, a 2017 review in Malaria Journal recounts. WHO certified the country malaria-free in 2023. CDC's Tajikistan page has no malaria section, and its list of vaccines and medicines has no malaria entry. Tajikistan isn't on CDC's global dengue list, and CDC's Zika page puts it among areas with no mosquitoes that spread Zika, the same Aedes mosquitoes that carry dengue. The yellow fever vaccine is neither recommended nor required.
Ticks in the south, sand flies in the villages
CDC lists Crimean-Congo hemorrhagic fever (CCHF), spread by tick bites or by touching the body fluids of an infected person or animal. It is endemic in Tajikistan, which records 5 to 38 cases a year from its southern regions, and researchers sequenced the virus from patients and from Hyalomma ticks collected in 2017–2023 (PLOS Neglected Tropical Diseases, 2026). The exposure is livestock contact and tick bites in the rural south. A hotel stay in Dushanbe isn't the risk. Walking through grass or near herds there, tuck long trousers into socks, use a repellent with 20% or more DEET as CDC suggests for ticks, check your whole body afterward and stay away from animal handling and slaughter.
CDC also lists leishmaniasis, spread by tiny sand flies that bite from dusk to dawn. A serosurvey published in 2016 tested 1,963 residents, mostly children, and 779 dogs and found visceral leishmaniasis antibodies in 35 people in Penjikent district and 9 in Darvaz district, most of them infants, and in up to 13% of dogs. The authors read that as active foci in villages. Penjikent is the usual gateway to the Fann Mountains' Seven Lakes, and Darvaz takes in Kalaikhum on the lower Pamir Highway. In village homestays in those districts, sleep under a net or in a closed, screened room, and cover up outdoors after dark.
Ticks and sand flies tend to be warm-season biters, so a spring or late-fall trip is likely to bring fewer. Mosquitoes aren't a reported problem on the trekking routes, and the high Pamir plateau around Murghab tends to have few biting insects of any kind.
Where you're going
Dushanbe
No mosquito-borne disease in the capital, and a hotel stay here isn't the CCHF exposure. The tick routine starts when you head into the southern countryside or spend time around livestock.
Fann Mountains & the Seven Lakes
Penjikent district, the usual gateway, has a documented visceral leishmaniasis focus in its villages, so sleep under a net in homestays there. On the trails themselves, bites tend to be few.
Pamir Highway & the Wakhan Valley
A high, dry route where biting insects tend to be few on the plateau. Darvaz district, around Kalaikhum on the lower stretch, has a visceral leishmaniasis focus, so use a net or a closed, screened room for homestay nights there.

The Tajikistan kit
- Permethrin 0.5% for trousers, socks and boots: treat them at home 48 hours before you fly. Treated fabric repels and kills on contact through several washes and helps against both ticks and sand flies. Clothing only, never skin.
- A repellent with 20% or more DEET for exposed skin, which CDC suggests for ticks.
- A lightweight bed net for homestays around Penjikent and Darvaz without screened rooms.
What travelers report
Paraphrased from a TripAdvisor thread and linked so you can read it in full. It isn't dated, and it speaks for one summer on one route.
- Fann Mountains · summer
Asked whether mosquitoes are a problem in summer, especially around the Fann Mountains, the one reply came from someone who had hiked there in summer and said no. TripAdvisor ↗
One more rule outlasts the trip. Any fever during or after your trip, especially after a tick bite, means a doctor visit, and so does a skin sore or a long-lasting fever after you get home. Tell the doctor you were in Tajikistan and where you stayed.
Traveler questions
Is there malaria in Tajikistan?
No. The World Health Organization certified Tajikistan malaria-free in 2023, after a 1990s epidemic of more than 400,000 cases had been brought back under control. CDC's Tajikistan page has no malaria section, and its list of vaccines and medicines has no malaria entry. The yellow fever vaccine is neither recommended nor required.
What is CCHF, and how do I avoid it?
Crimean-Congo hemorrhagic fever is a virus spread by tick bites or by touching the body fluids of an infected person or animal. Tajikistan records 5 to 38 cases a year, from its southern regions, and the exposure is livestock contact and tick bites in the countryside. In the rural south, wear long trousers tucked into socks, use a repellent with 20% or more DEET as CDC suggests for ticks, check your whole body after walks and stay away from animal handling and slaughter. See a doctor for any fever after a tick bite.
Are there sand flies on the Pamir Highway or near the Seven Lakes?
The documented foci are in villages. A study published in 2016 found visceral leishmaniasis antibodies in residents of Penjikent district, the gateway to the Seven Lakes, and Darvaz district, around Kalaikhum on the lower Pamir Highway, and in up to 13% of dogs there. Sand flies bite from dusk to dawn, so sleep under a net or in a closed, screened room in homestays in those districts and cover up after dark.
