Turkmenistan is malaria-free. The desert sand fly is the bite to plan for.
- No CDC travel notice for mosquito-borne disease
The World Health Organization certified Turkmenistan malaria-free in 2010, and CDC lists no dengue or Zika. Cutaneous leishmaniasis, spread by night-biting sand flies, occurs in the Merv oasis and the desert, so a night at the Darvaza crater or an evening near Mary calls for a dusk-to-dawn routine.
Are there mosquitoes in Turkmenistan? A few, and CDC's Turkmenistan page lists no disease they spread. The World Health Organization certified the country malaria-free in 2010, and there are no reports of dengue, chikungunya or Zika. The insect to plan around is the phlebotomine sand fly, which spreads cutaneous leishmaniasis, a skin infection, in the desert and the oases.
Sand flies in the desert and the Merv oasis
CDC's Turkmenistan page lists leishmaniasis, spread by "sand fly bite." Its skin form has natural foci across the deserts of Turkmenistan and its neighbors, tied to colonies of great gerbils, a 2018 review explains. The Murgab oasis around Mary, where the ruins of Merv stand, is a long-studied focus. It can reach visitors. A 2013 report in the Journal of Travel Medicine described four European travelers who came home from western Turkmenistan with Leishmania major skin infections, some with unusual or multiple sores.
Sand flies bite quietly from dusk to dawn and are rarely noticed. A daytime visit to Merv carries little risk. A night at the Darvaza gas crater or an evening in the oasis is when the routine matters. Put DEET 20–30% or picaridin 20% on exposed skin before sunset, wear long sleeves and trousers after dark, and sleep in a closed tent, yurt or air-conditioned room. Sand flies can be small enough to slip through ordinary mosquito netting, so a closed shelter does more than a net. CDC recommends permethrin-treated clothing and gear.
CDC also lists Crimean-Congo hemorrhagic fever (CCHF), spread by tick bites and by touching the body fluids of an infected person or animal. It's a risk around livestock, not on city sightseeing days. Avoid handling animals, and check for ticks after rural walks.
When to go
April–May and September–October tend to be the easiest months, warm rather than scorching in the desert, and the best time for a comfortable Darvaza overnight. June to August is the hardest stretch, with extreme heat and the busiest sand flies at desert camps and in the Merv oasis. November to March tends to be cold and close to bite-free. Ashgabat is an easy stop in any month.
Where you're going
How the main stops compare across the year.
Ashgabat
A hotel-based city stay at the foot of the Kopet Dag, with little bite exposure. Hotels tend to be air-conditioned, so sightseeing days need nothing extra.
Darvaza gas crater
An overnight in the Karakum Desert, in sand fly country. Spray before sunset, cover up after dark and zip the tent or yurt shut. The moths and beetles circling the flames don't bite.
Merv & the Mary oasis
The ruins near Mary sit in the Murgab oasis, a long-studied leishmaniasis focus. A day visit carries little risk; staying into dusk or overnight in the oasis calls for the full sand fly routine.

The Turkmenistan kit
- Picaridin 20% travel sprays: odorless and easy to reapply before sunset at a desert camp. One 3.4 oz bottle covers about a week of daily use for one person.
- Permethrin 0.5% for evening clothes and gear: treat a long-sleeved shirt, trousers and socks at home 48 hours before you fly, as CDC recommends against sand flies. Clothing and gear only, never skin.
- A light long-sleeved shirt and long trousers for after dark, even when the desert evening is still warm.
What travelers report
Paraphrased from a FlyerTalk trip report and linked so you can read it in full. It isn't dated, and it describes one stop in northern Turkmenistan.
- Dashoguz (northern Turkmenistan)
In a trip report on flying Turkmenistan Airlines, a traveler counted the flies and mosquitoes, along with a waterless toilet in an airless hotel room, among the reasons a stop in Dashoguz was not great; the same poster found the ruins at Merv memorable. FlyerTalk ↗
One rule outlasts the trip. Any fever during or after your trip means a doctor visit, especially after a tick bite, and so does a skin sore that doesn't heal in the weeks after you get home. Tell the doctor you were in Turkmenistan and where you slept.
Traveler questions
Is there malaria in Turkmenistan?
No. The World Health Organization certified Turkmenistan malaria-free in 2010. CDC's Turkmenistan page has no malaria section and lists no malaria medicine. The yellow fever vaccine is not recommended, and it isn't required for entry.
Are there bugs at the Darvaza gas crater?
The crater has a reputation for drawing swarms of moths, beetles and other insects to its light and heat after dark, and those don't bite. The biter to think about is the sand fly, which is hard to see. Spray before sunset, wear long sleeves and trousers after dark, and sleep in a closed tent or yurt.
What is cutaneous leishmaniasis, and how do I avoid it?
It's a skin infection caused by a parasite that phlebotomine sand flies spread when they bite, from dusk to dawn. CDC lists leishmaniasis for Turkmenistan, and it occurs in the desert and the Merv oasis. A 2013 report described four European travelers infected in western Turkmenistan. Use DEET 20–30% or picaridin 20% after dark, cover up and sleep in a closed shelter. See a doctor about any skin sore that doesn't heal in the weeks after the trip, and say where you traveled.
