Yaws is a non-venereal endemic treponemal infection caused by Treponema pallidum sub-species pertenue, a bacterium closely related to Treponema pallidum ssp. pallidum, the agent of venereal syphilis. Yaws predominantly affects children living in tropical regions of the world. It causes lesions of th

e skin, mucous membranes and bones which, without treatment, can become chronic and destructive. There is no widely available test to distinguish yaws from syphilis. Thus, migration of people from yaws-endemic areas to developed countries may present clinicians with diagnostic dilemmas. The other endemic treponemal infections are bejel (endemic syphilis) caused by Treponema pallidum ssp. endemicum and pinta caused by Treponema carateum.

Trachoma disease
Trachoma is a sequela following infection by the bacterium Chlamydia trachomatis (C. trachomatis). The disease is preventable, but still the cause of blindness in 1.9 million people world wide.
Trachoma is a bacterial eye infection found in poor, isolated communities lacking basic hygiene, clean water, and adequate sanitation.
Trachoma is easily spread from person to person through eye-seeking flies, hands, and clothes. Repeated infection over time leads to scarring and inward turning o

f the eyelid, causing the eyelashes to scratch the cornea — a very painful condition called trachomatous trichiasis — which eventually causes blindness if left untreated.
more
Trachoma is a bacterial eye infection, not unlike the common ‘pink-eye’ or conjunctivitis. Repeated reinfection, combined with the body’s immune reaction, often has devastating consequences.
Trachoma starts as an infection of the membrane that covers the outside of the eyeball and lines th
...
e inner surface of the eyelids (conjunctiva). Repeated infections can over years eventually lead to scarring that causes the margin of the eyelid to turn inwards.

People with Guinea worm disease (GWD) have no symptoms for about 1 year. Then, the person begins to feel ill. Symptoms can include the following:
Slight fever
Itchy rash
Nausea
Vomiting
Diarrhea
Dizziness
A blister then develops. This blister can form anywhere on the skin. However, the blis
...
ter forms on the lower body parts in 80%–90% of cases. This blister gets bigger over several days and causes a burning pain. The blister eventually ruptures, exposing the worm. The infected person may put the affected body part in cool water to ease the symptoms or may enter water to perform daily tasks, such as fetching drinking water. On contact with water, the worm discharges hundreds of thousands of larvae into the water.

Leptospirosis is a zoonotic disease with epidemic potential, especially after a heavy rainfall,
caused by a bacterium called Leptospira. Leptospira interrogans is pathogenic to humans and
animals, with more than 200 serologic variants or serovars. Humans usually acquire
leptospirosis through dire
...
ct contact with the urine of infected animals or a urine-contaminated
environment. Human-to-human transmission occurs only very rarely. Leptospirosis may present
with a wide variety of clinical manifestations, from a mild illness that may progress to a serious
and sometimes fatal disease. Its symptoms may mimic many diseases, such as influenza,
dengue and other viral haemorrhagic diseases; making the correct diagnosis (clinical and
laboratory) at the onset of symptoms is important to prevent severe cases and save lives,
primarily in outbreak situations.

Yaws, a neglected tropical disease (NTD) of the skin caused by the bacterium Treponema pallidum subspecies pertenue, is targeted in the latest WHO NTD Roadmap for eradication by 2030. In January, 2022, WHO published a manual that outlines the key activities that Ministries of Health in endemic count

ries should undertake to achieve this goal. The aim of the manual is to provide guidance on surveillance and evaluation of yaws as programmes progress towards eradication. However, yaws eradication in Africa faces several challenges.

J Glob Health Sci. 2020 Jun;2(1):e3. A group of enzootic and zoonotic protozoan infections, the leishmaniases constitute among the most severely neglected tropical diseases (NTDs) and are found in all continents except Oceania. Representing the most common infectious diseases, NTDs comprise an open-
...
ended list of some 20 parasitic, bacterial, viral, protozoan and helminthic infections. Called “diseases of the poor,” because of their characteristic prevalence in poor populations regardless of a country's income status, they infect over one billion people in over 140 countries, with about 90% of the global burden in Africa. While NTDs do not contribute significantly to global deaths, they are debilitating and remain the most common infections among the poor worldwide, preventing them from escaping poverty by impacting livelihoods such as agriculture and livestock, and affecting cognitive, developmental and education outcomes.
