Because T. pallidum pertenue is temperature- and humidity-dependent, yaws is found in humid tropical forest regions in South America, Africa, Asia and Oceania. About three quarters of people affected are children under 15 years of age, with the greatest incidence in children 6-10 years old Yaws is an infection caused by a form of the Treponema pallidum bacteria. It is closely related to the bacterium that causes syphilis, but this form of the bacterium is not sexually transmitted. Yaws mainly affects children in rural, warm, tropical areas, such as, Africa, Western Pacific islands, and Southeast Asia Yaws, also called frambesia, contagious disease occurring in moist tropical regions throughout the world. It is caused by a spirochete, Treponema pertenue, that is structurally indistinguishable from T. pallidum, which causes syphilis Yaws is a common chronic infectious disease that occurs mainly in warm humid regions such as the tropical areas of Africa, Asia, South and Central Americas, plus the Pacific Islands. The disease has many names (for example, pian, parangi, paru, frambesia tropica)

Yaws is a disease of children (peak incidence at age 2 to 10 years) that is most common in warm, humid regions, including South and Central America, the Caribbean, equatorial Africa, and the equatorial islands of Southeast Asia.7,10,11 The prevalence and incidence of yaws declined markedly during the yaws eradication campaigns of the 1950s, but in recent years the disease has again become more common Yaws is an infectious disease that affects the skin and bones. It's a tropical illness that was once common in West Africa, Indonesia, New Guinea, the Solomon Islands, Haiti, Dominica, Peru, Colombia, Ecuador and parts of Brazil

The disease is found primarily in poor communities in warm, humid and tropical forest areas of Africa, Asia, Latin America and the Pacific. Most affected populations live at the end of the road, far from health services. Poverty, low socio-economic conditions and poor personal hygiene facilitate the spread of yaws. Scope of the proble Yaws is transmitted by direct skin-to-skin, non-sexual contact with infectious lesions. Because T pallidum pertenue is temperature and humidity dependent, yaws is found in warm, moist climates, mainly in forested tropical regions. The incidence of yaws skin lesions is higher in the wet season than in the dry season; 5

So Treponema pertenue, the bacterium that caused yaws in Hispaniola, might mutate to Treponema pallidum in Europe's climate, thus causing syphilis there Yaws is a lesser-known treponemal disease primarily of the skin that affects both humans and other primates in warm, tropical environments. Finding it in northern Europe in the mid-15th century.

Meteorology and Climate - (PP500) It is concluded that yaws is a rare disease in the United States in spite of its prevalence in the West Indies, that being a tropical disease it would not thrive in the northern states, and that even should it obtain a foothold in the southern states it could easily be eradicated.. Secondary yaws lesions may occur near primary lesions or elsewhere on the body and may last for weeks to more than 6 months. Macules, papules, nodules, and hyperkeratotic lesions may appear. Climate influences the morphology and the number of lesions. In the dry season, lesions are fewer and macular in appearance

Yaws: MedlinePlus Medical Encyclopedi

Yaws, a disease that penicillin nearly eradicated 40 years ago, has been re-emerging in rural tropical Africa, Southeast Asia and the Pacific islands — but a new study has shown that a modern. In the hot, humid climate of Sub-Saharan Africa, treponematosis originated from nonhuman primates as a childhood disease (yaws) transmitted by skin-skin contact. The bacteria evolved alongside humans in migrating hunter-gatherer populations throughout the Paleolithic In the 1950s, yaws was among the first diseases targeted for global eradication. Initial efforts were successful in reducing global disease burden from 50 million people to just 2.5 million by 1964, before surging back in recent decades as health care authorities redirected their funds and attention to other priorities

climate change may have on human health and analyses the various direct and indirect impacts that climate change will have on African populations. Due to the emerging nature of the issue and literature, there are many gaps in knowledge on the impacts climate change will have on human health They were denied access to the basic necessities for good sanitation, which made ideal breeding grounds for the disease. Although the climate of the colonial American south was milder than either Jamaica or Africa, the conditions were similar enough to the tropical regions where yaws is thought to have originated for the disease to proliferate Yaws is an infection that mainly affects the poorest populations living in humid tropical areas. We reviewed the literature on yaws, the most common non-venereal treponemal infection, using the standard Prescrire methodology. Yaws is often transmitted directly from person to person Yaws is found in tropical regions with warm and humid environments. The disease mostly affects children between the age of 2 to 15 who also serve as reservoirs for the spirochete. Infection is spread by direct skin to skin contact, and there has been a consideration for fly vectors although the latter is unproven Yaws is an endemic relapsing treponematosis caused by Treponema pallidum subspecies pertenue and is one of 17 neglected tropical diseases affecting primarily young children (<15 years of age) living in tropical regions with an average temperature of 80°F [1-3]. In endemic regions, it is known by many names, including pian (French)

Definition of yaws : a contagious tropical disease especially of children caused by a spirochete (Treponema pertenue) closely resembling the causative agent of syphilis and marked by infectious ulcerative skin lesions with later bone involvement — called also frambesia Examples of yaws in a Sentenc Meteorology and Climate - (PP500) It is concluded that yaws is a rare disease in the United States in spite of its prevalence in the West Indies, that being a tropical disease it would not thrive in the northern states, and that even should it obtain a foothold in the southern states it could easily be eradicated..

Yaws is a mutilating disease that leads to disability. The infection is transmitted through direct contact with an affected person. In Lihir, the scarcity of running water, lack of sanitation and overcrowded living conditions facilitate transmission of the disease, particularly among children aged between 5 and 15 years Yaws is a tropical disease that infects the skin, bones and cartilage. It is caused by the bacterium Treponema pallidum subspecies pertenue. Mostly children in remote tropical areas of Africa,..

During the coronavirus disease 2019 (COVID‑19) pandemic, some countries, including Indonesia, have faced a double burden with regards to disease control. As Indonesia is a tropical country, it serves as a suitable host for disease vectors and multiple microorganisms of causative agents of disease. In total, five of the neglected tropical diseases (NTDs) should be a consideration in Indonesia. Targets include the eradication of dracunculiasis (guinea worm) and yaws and a 90% reduction in the need for treatment for NTDs by 2030. `Ending the neglect to attain the Sustainable Development Goals: a road map for neglected tropical diseases 2021-2030´aims to accelerate programmatic action and renew momentum by proposing concrete actions.
