There are 3 main forms of leishmaniases: visceral (the most serious form because it is almost always fatal without treatment), cutaneous (the most common, usually causing skin ulcers), and mucocutaneous (affecting mouth, nose and throat).
Leishmaniasis is caused by protozoan parasites which are tra...nsmitted by the bite of infected female phlebotomine sandflies.
The disease affects some of the world’s poorest people and is associated with malnutrition, population displacement, poor housing, a weak immune system and lack of financial resources.
An estimated 700 000 to 1 million new cases occur annually.
Only a small fraction of those infected by parasites causing leishmaniasis will eventually develop the disease.

Fascioliasis is an animal parasitic disease (in cattle and sheep, but also pigs, donkeys, Llamas and alpacas that can be transmitted to humans. The infection is caught when aquatic or semi-aquatic plants with the larvae of the worm attached to their stem or leaves are ingested raw or poorly cooked. ...Once in the human body, the worm lodges itself in the main bile ducts and is responsible for severe morbidity. Endemic areas are distributed globally, but some of the most affected communities are found in the Andean highlands of South America. Triclabendazole is the only drug recommended for prevention and treatment and is provided free-of-charge to endemic countries through WHO. It can be distributed in mass interventions when clusters of cases are detected.

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.

Snakebite envenoming is a neglected tropical disease (NTD) that is responsible for enormous suffering, disability and premature death on every continent. As over 5.8 billion people are at risk of encountering a venomous snake, it is not surprising but no less tragic that almost 7400 people every
da...y are bitten by snakes, and 220–380 men, women and children die as a result, adding up to about 2.7 million cases of envenoming and 8100–138 000 deaths a year.

Snakebite envenoming affects millions of people worldwide annually and is a significant source of mortality. Preventing and treating the problem is complex and requires collaboration among the fields of public health, medicine, ecology, and laboratory science. After being removed from the category A... neglected tropical disease (NTD) list in 2013, snakebite envenoming was reinstated in 2017 in response to antivenom shortages and advocacy from researchers and international NGOs. In 2019, the World Health Organization (WHO) set a target to halve the number of deaths and cases of snakebite envenoming by 2030.

As of 12 December 2022, over 645 million people worldwide have been diagnosed with COVID-19, with over 6.6 million deaths (4).
The Omicron variant, which emerged in late November 2021, and its subvariants, are now the dominant circulating viruses, contributing to the ongoing surge in several countr...ies (4). Vaccination has substantially reduced case numbers and hospitalizations in many countries,but limitations in global access to vaccines mean that many populations, including those in low- and middle-income countries, remain vulnerable. Even in vaccinated individuals, uncertainties remain about duration of protection and efficacy, and the degree of crossprotection with new variants.
There remains a need for more effective treatment and management for those affected by COVID-19. The pandemic – and the
explosion of both research and misinformation – has highlighted the need for trustworthy, accessible and regularly updated living
guidelines to place emerging findings into context and provide clear recommendations for clinical practice

Cervical cancer continues to be a significant public health problem and a major cause of premature mortality among women, disproportionately affecting the socioeconomically disadvantaged population in low- and middle-income countries (LMICs). In the absence of implementing the known evidence-based, ...cost-effective interventions, the number of deaths per year is projected to reach approximately 416 000 globally in 2035. It was estimated in 2020 that 32% of incident cervical cancer cases and 34% of cervical cancer deaths in the world occurred in the 11 Member States of the WHO South-East Asia (SEA) Region. In 2020, 190 874 new cases and 116 015 deaths were estimated due to cervical cancer, which is the third commonest cancer in the Region

Rabies is entirely preventable, and vaccines, medicines, tools and technologies have long
been available to prevent people from dying of dog-mediated rabies. Nevertheless, rabies still
kills about 60 000 people a year, of whom over 40% are children under 15, mainly in rural areas
of economically ...disadvantaged countries in Africa and Asia. Of all human cases, up to 99% are
acquired from the bite of an infected dog.

Clin Microbiol Infect 2010; 16: 225–231 Abstract In non-endemic countries, acute (invasive) schistosomiasis (AS) is typically seen in non-immune travellers, whereas chronic schistosomiasis is more frequently diagnosed in immigrants. Travellers with AS initially present with non-specific signs such... as fever, cough, headache, and urticaria. Life-threatening cardiac and neurological complications may occur. The positive diagnosis of AS relies on seroconversion, which appears together with hypereosinophilia approximately 3 weeks after the onset of symptoms. When prescribed during AS, praziquantel usually does not prevent the chronic phase of the disease and is associated with exacerbation of signs and symptoms in approximately 50% of cases. According to the published literature, corticosteroids may be recommended alone or in association with praziquantel. When associated with corticosteroids, pharmacokinetic interactions may impair the efficacy of praziquantel. We suggest that corticosteroids should be restricted to use in patients with systemic complications of AS, whereas praziquantel should be initiated only when ova are detected in either stools or urine, depending on the culprit species.

Each year 1–2 million people are diagnosed with a tropical disease called leishmaniasis, which is caused by single-celled parasites. People are infected when they are bitten by sandflies carrying the parasite, and often develop skin lesions around the bite site. Though mild cases may recover on th...eir own or with treatment, sometimes the parasites multiply and spread elsewhere causing further skin lesions and facial disfigurement. Furthermore, the parasites can also infect internal organs such as the spleen and the liver, which without treatment can be fatal.
