Background: East African trypanosomiasis is an uncommon, potentially lethal disease if not diagnosed and treated in a timely manner. South Africa, as a centre for emergency medical evacuations from much of sub-Saharan Africa, receives a high proportion of these patients, mostly tourists and expatria...te residents.
Methods: The cases of East African trypanosomiasis patients evacuated to South Africa, for whom diagnostic and clinical management advice was provided over the years 2004–2018, were reviewed, using the authors’ own records and those of collaborating clinicians.
Results: Twenty-one cases were identified. These originated in Zambia, Malawi, Zimbabwe, Tanzania, and Uganda. Nineteen cases (90%) had stage 1 (haemolymphatic) disease; one of these patients had fatal myocarditis. Of the two patients with stage 2 (meningoencephalitic) disease, one died of melarsoprol encephalopathy. Common problems were delayed diagnosis, erroneous assessment of severity, and limited access to treatment.
Conclusions: The key to early diagnosis is recognition of the triad of geographic exposure, tsetse fly bites, and trypanosomal chancre, plus good microscopy. Elements for successful management are rapid access to specific drug treatment, skilled intensive care, and good laboratory facilities. Clinical experience and the local stock of antitrypanosomal drugs from the World Health Organization have improved the chance of a successful outcome in the management of East African trypanosomiasis in South Africa; the survival rate over the period was 90.5%.

Yaws is a chronic skin infection characterized by papillomas (noncancerous lumps) and ulcers. It is caused by the bacterium Treponema pallidum subspecies pertenue, which belongs to the same group of bacteria that causes venereal syphilis.
The trematodes Fasciola hepatica (also known as the common liver fluke or the sheep liver fluke) and Fasciola gigantica are large liver flukes (F. hepatica: up to 30 mm by 15 mm; F. gigantica: up to 75 mm by 15 mm), which are primarily found in domestic and wild ruminants (their main definitive host...s) but also are causal agents of fascioliasis in humans.

• Leptospirosis is a disease that is caused by
spirochete bacteria in the genus Leptospira.
There are 10 pathogenic species, and more
than 250 pathogenic serovars.
• While leptospirosis occurs worldwide, it is
more common in tropical or sub-tropical
climates.
Les objectifs de ce document sont de contribuer à ce que l’ulcère de Buruli (infection
à Mycobacterium ulcerans) soit mieux reconnu et d’inciter à intensifier les efforts pour
détecter les cas à un stade précoce de l’infection. Aujourd’hui, les malades peuvent
être guéris par des... antibiotiques s’ils sont diagnostiqués suffisamment tôt, ce qui
permet d’éviter des souffrances et des incapacités inutiles. Nous espérons que tous les
utilisateurs de ce document participeront à la réalisation de ces objectifs.

Chagas disease (American trypanosomiasis) is endemic in 21 countries of the Americas, where control is largely focused on elimination of the domestic insect vectors (Triatominae) coupled with measures to extend and improve the screening of blood donors in order to avoid tranfusional transmission. Th...rough national programmes and multinational initiatives coordinated by WHO-PAHO, much has been accomplished in these domains in terms of reducing transmission. Attention now turns to consolidating the successes in interrupting transmission, and improved treatment for those already infected and those who may become affected in the future. This article, based on technical discussions at the "Epidemiological and Sociological Determinants of Chagas Disease, Basic Information to Establish a Surveillance and Control Policy " meeting in Rio de Janeiro, is designed to open the debate on appropriate strategies for continuation of the successful initiatives against Chagas disease.

Rabies is a fatal viral zoonosis and serious public health problem.1 All mammals are believed to be susceptible to the disease, and for the purposes of this document, use of the term animal refers to mammals. The disease is an acute, progressive encephalitis caused by viruses in the genus Lyssavirus....
2 Rabies virus is the most important lyssavirus globally. In the
United States, multiple rabies virus variants are maintained in wild mammalian reservoir populations such as raccoons, skunks, foxes, and bats. Although the United States has been declared free from transmission of canine rabies virus variants, there is always a risk of reintroduction of these variants.The rabies virus is usually transmitted from animal to animal through bites. The incubation period is
highly variable. In domestic animals, it is generally 3 to 12 weeks, but can range from several days to months, exceeding 6 months.8 Rabies is communicable during the period of salivary shedding of rabies virus. Experimental and historic evidence documents that dogs, cats, and ferrets shed the virus for a few days prior to the onset of clinical signs and during illness. Clinical signs of rabies are variable and include inappetance, dysphagia, cranial nerve deficits, abnormal behavior, ataxia, paralysis, altered vocalization, and seizures. Progression to death is rapid. There are currently no known effective rabies antiviral drugs.

Several Public Health Services and general practitioners in the Netherlands observed an increase in scabies in the Netherlands. Since individual cases of scabies are not notifiable in the Netherlands, the epidemiological situation is mostly unknown. To investigate the scabies incidence in the Nether...lands, we described the epidemiology of scabies between 2011 and 2021.

Theodor Bilharz, a German professor of anatomy and chief of surgery at the Kasr El Ani Hospital of Cairo from 1850, first identified an infective organism, Distomum hematobium in 1851, which was renamed Schistosoma haematobium in 1858. It arose from a cestode worm, Hymenoleptis nana, lying in the sm...all colon of an Egyptian patient. He also discovered a trematode worm at the same time from an autopsy, thought to be the cause of urinary Schistosomiasis. Bilharz died from typhoid fever in 1862 at the age of 37. The Theodor Bilharz Research Institute in Giza, Egypt, stands as a tribute to him today. F. Milton published the first recorded peer-reviewed article report on Schistosomiasis in 1914.

Worldwide, over 6 million people are infected with Trypanosoma cruzi, the pathogen that causes Chagas disease (CD). In the Americas, CD creates the greatest burden in disability-adjusted life years of any parasitic infection. In Co...lombia, 437 000 people are infected with T. cruzi, of whom 131 000 suffer from cardiomyopathy. Colombia’s annual costs for treating patients with advanced CD reach US$ 175 016 000. Although timely etiological treatment can significantly delay or prevent development of cardiomyopathy—and costs just US$ 30 per patient—fewer than 1% of people with CD in Colombia and elsewhere receive it.
