Does African sleeping sickness make you sleep?

African trypanosomiasis is a parasitic disease transmitted by the tsetse fly. It gets its nickname ‘sleeping sickness’ because symptoms can include a disturbed sleep pattern.

What are the three stages of disease for African sleeping sickness?

The durations of untreated stage 1 (early stage, haemo-lymphatic) and stage 2 (late stage, meningo-encephalitic) human African trypanosomiasis (sleeping sickness) due to Trypanosoma brucei gambiense are poorly quantified, but key to predicting the impact of screening on transmission.

Is African trypanosomiasis a virus or bacteria?

Parasites – African Trypanosomiasis (also known as Sleeping Sickness) African Trypanosomiasis, also known as “sleeping sickness”, is caused by microscopic parasites of the species Trypanosoma brucei. It is transmitted by the tsetse fly (Glossina species), which is found only in sub-Saharan Africa.

How long does African sleeping sickness last?

It’s a short-term (acute) illness that may last several weeks to months. People from the U.S. who travel to Africa are rarely infected. On average, 1 U.S. citizen is infected every year.

How is sleeping sickness diagnosed?

How is sleeping sickness diagnosed? Diagnosing sleeping sickness involves invasive tests to confirm a positive result by the rapid diagnostic tests used for community screening. Diagnosis requires confirming the presence of the parasite in any body fluid, usually in the blood and lymph system through a microscope.

What are the stages of African trypanosomiasis?

Infection occurs in two stages, an initial haemolymphatic stage followed by a meningoencephalitic stage after the trypanosomes invade the central nervous system (CNS). However, many of the signs and symptoms are common to both stages, making it difficult to distinguish between the two stages by clinical features alone.

Is sleeping sickness a virus or bacteria?

Human African trypanosomiasis, also known as sleeping sickness, is a vector-borne parasitic disease. It is caused by infection with protozoan parasites belonging to the genus Trypanosoma.

How can African trypanosomiasis be prevented?

How can I prevent African trypanosomiasis and prevent other insect bites?

  1. Wear protective clothing, including long-sleeved shirts and pants.
  2. Wear neutral-colored clothing.
  3. Inspect vehicles for tsetse flies before entering.
  4. Avoid bushes.
  5. Use insect repellant.

Where is sleeping sickness most common?

West African trypanosomiasis can be contracted in parts of central Africa and in a few areas of West Africa. Most of the reported cases are found in central Africa (Democratic Republic of Congo, Angola, Sudan, Central African Republic, Republic of Congo, Chad, and northern Uganda).

Who is at risk for African sleeping sickness?

Who is at risk for African sleeping sickness? The only people at risk for African sleeping sickness are those who travel to Africa. That’s where the tsetse fly is found. The parasites that cause the disease are passed on only by the tsetse fly.

Is there a vaccine for sleeping sickness?

There is no vaccine or drug for prophylaxis against African trypanosomiasis. Preventive measures are aimed at minimizing contact with tsetse flies.

How many people have died from sleeping sickness?

Estimated Number of the Deaths When left untreated, the mortality rate of African sleeping sickness is close to 100%. It is estimated that 50,000 to 500,000 people die from this disease every year.

Can trypanosomiasis be cured?

There is no test of cure for African trypanosomiasis. After treatment, patients should be closely followed for 24 months and monitored for relapse. Recurrence of symptoms will require examination of body fluids, including CSF, to detect the presence of trypanosomes.

Which organ is affected by sleeping sickness?

Sleeping sickness is an infection caused by tiny parasites carried by certain flies. It results in swelling of the brain.

Is there a test for sleeping sickness?

CSF testing is done after a parasitologic diagnosis has been made by microscopic examination of blood, lymph node aspirates, chancre fluid, or bone marrow or when indications of infection are present that justify a lumbar puncture (e.g., clinical signs and symptoms of sleeping sickness or strong serologic suspicion).

What is the contagious period for sleeping sickness?

Usually 12 to 15 days elapse before flies that have picked up the parasites become infective toward humans.

Does sleeping sickness still exist?

Without treatment sleeping sickness typically results in death. The disease occurs regularly in some regions of sub-Saharan Africa with the population at risk being about 70 million in 36 countries. An estimated 11,000 people are currently infected with 2,800 new infections in 2015.

What do you do if you get bitten by a tsetse fly?

Seek immediate medical attention if bitten by a tsetse fly (the bite is painful) and symptoms appear. If untreated, African Trypanosomiasis can lead to a coma and be fatal. Treatment includes taking antiparasitic drugs.

Is there a vaccine for Chagas disease?

There is no vaccine for Chagas disease. T. cruzi can infect many species of triatomine bugs, the vast majority of which are found in the Americas. Vector control has been the most effective method of prevention in Latin America.

How many cases of sleeping sickness are there?

Although epidemics of sleeping sickness were a significant public health problem in the past, the disease is reasonably well-controlled at present, with less than 2000 cases reported in 2017–2018 (https://www.who.int/gho/neglected_diseases/human_african_trypanosomiasis/en/ ).

Are tsetse flies attracted to light blue?

The tsetse fly is attracted to bright colors, very dark colors, metallic fabric, particularly the colors blue and black.

Where are tsetse flies located?

Tsetse flies are bloodsucking flies of the genus Glossina. They occur only in tropical Africa and are important as vectors of African trypanosomiasis in both humans and animals. Sleeping sickness, as it is commonly called, is generally fatal in humans if left untreated.
