What kind of doctor treats Dracunculiasis?
An infectious disease doctor, a doctor who treats infections from germs and parasites, can treat dracunculiasis. It is also called Guinea worm disease. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is dracunculiasis?
Dracunculiasis is an infection caused by a parasite named Dracunculus medinensis. A parasite is a living thing that lives on or inside another living thing. The infection is also called Guinea worm disease.
The disease affects communities in remote parts of Africa that do not have safe water to drink. Only a handful of countries still have it.
Symptoms
People do not usually have symptoms until about one year after infection. Then a mature female worm makes a blister on the skin. The worm comes out through this blister. It can be up to 3 feet (1 meter) long. Signs can include:
- Fever, swelling, and pain in the area, starting a few days to hours before the worm comes out.
- A very painful, burning blister that bursts within 24 to 72 hours.
- A wound where the worm comes out, most often on the legs and feet.
- Infection of the wound by bacteria, which can happen as the worm comes out.
When the worm comes out, it can be very painful and disabling. Removing it can take a long time.
Causes and who gets it
People get Guinea worm disease by drinking unfiltered water from ponds or other still water. This water can hold copepods, which are tiny water fleas. The copepods carry larvae, the young form of the worm. It is not normally caught from flowing water such as rivers and streams. People can also get it by eating raw or undercooked fish or frogs that carry the larvae.
It can happen at any age but is most common in young adults 15 to 45 years old. Farmers, herders, and people who fetch water for the home may be more likely to get infected. They may drink unfiltered water while away from home. Having the disease once does not make you immune. You can get it again.
How doctors diagnose it
Guinea worm disease shows itself when a mature female worm makes a blister on the skin and the worm comes out through it.
Treatment
There is no drug to treat Guinea worm infection and no vaccine to prevent it. Care means slowly pulling out the whole worm and caring for the wound. Steps include:
- Keep the infected person out of drinking water sources.
- Soak the wound in water, far from any water source. This helps the worm release larvae and makes it easier to remove.
- Wrap the worm around rolled gauze and pull gently. Stop pulling when you feel resistance, so the worm does not break.
- Put antibiotic ointment on the wound and cover it with clean gauze. This helps prevent infection.
- Medicines such as aspirin or ibuprofen can ease pain and swelling.
Pulling out the whole worm can take several days to weeks. The steps are repeated every day until the whole worm is out.
Prevention starts with safe water. Cloth and pipe filters remove copepods from drinking water. Safe supplies such as borehole wells and health education also help.
When to see a doctor
Get medical care if the worm breaks and part of it stays inside. This raises the risk of strong swelling and infection. It can also make the pain worse and last from weeks to months.
Get medical care for any Guinea worm wound, and get care quickly if the wound looks infected. Wound infection can lead to cellulitis, a skin infection, or an abscess, a pocket of pus. It can also lead to tetanus, a joint infection, or sepsis, a severe whole-body reaction to infection.
Call 911 or go to the emergency room for fainting, a sudden change in mental state, or severe trouble breathing.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either kind of doctor can review your symptoms and travel history, help with wound care, and refer you to an infectious disease doctor when needed.
Common questions
Can you get dracunculiasis more than once?
Yes. People do not become immune, so they can get it again. Having had the disease the year before is a risk factor for new infection.
Is there a medicine or vaccine for Guinea worm disease?
No. There is no drug to treat it and no vaccine to prevent it. Care focuses on removing the worm and caring for the wound.
Where does Guinea worm disease happen?
It happens in remote parts of Africa that do not have safe water to drink. Only a handful of countries still have the disease.
How can Guinea worm disease be prevented?
Drinking safe, filtered water helps prevent it. Cloth and pipe filters remove copepods, the tiny water fleas that carry the larvae. Safe water supplies and health education also help.
