Lymphatic filariasis is a vector-borne neglected tropical disease that causes damage of the lymphatic system and can lead to lymphoedema (elephantiasis) and hydrocele in infected individuals. The global baseline estimate of persons affected by lymphatic filariasis is 25 million men with hydrocele an...d over 15 million people with lymphoedema. At least 36 million persons remain with these chronic disease manifestations. The disease is endemic in 72 countries. In 2016, an estimated total population of 856 million were living in areas with ongoing transmission of the causative filarial parasites and requiring mass drug administration (MDA). Lymphatic filariasis disfigures and disables, and often leads to stigmatization and poverty. Hundreds of millions of dollars are lost annually due to reduced productivity of affected patients. WHO has ranked the disease as one of the world’s leading causes of permanent and long-term disability.

Arsenic contaminated tube well water was first detected in Bangladesh in early 1990s. The arsenic comes from naturally arsenic-rich material delivered by the region's river systems, deposited over many years to make up the land of Bangladesh. Arsenic contamination is not caused by tube wells, or by ...irrigation or application of fertilizers.
Today, although 98 per cent of the population uses an improved drinking water source the safe water coverage of Bangladesh is 86 per cent because of arsenic contamination.

In the Region of the Americas, the leishmaniases are a group of diseases caused by various species of Leishmania, which cause a set of clinical syndromes in infected humans that can involve the skin, mucosa, and visceral organs. The spectrum of clinical disease is varied and depends on the interacti...on of several factors related to the parasite, the vector, and the host. Cutaneous leishmaniasis is the form most frequently reported in the Region and nearly 90% of cases present single or multiple localized lesions. Other cutaneous clinical forms, such as disseminated and diffuse cutaneous leishmaniasis, are more difficult to treat and relapses are common. The mucosal form is serious because it can cause disfigurement and severe disability if not diagnosed and treated early on. Visceral leishmaniasis is the most severe form, as it can cause death in up to 90% of untreated people.

COVID-19 outbreak is associated with the generation of many types of infectious wastes, including infected masks, gloves and other protective equipment, together with a higher volume of general waste of the same nature.
It is Zika virus (ZIKV) that most often causes these neurological effects it appears to be the only arbovirus than can cause congenital malformations such as microcephaly. In any case, more scientific tests are needed to establish the causal relationship between the virus and this malformation (7-10...).
This document is a practical tool designed to help health workers improve clinical diagnosis and provide timely care for patients infected
with the dengue, chikungunya, or Zika virus. It is intended mainly for
health workers in primary care facilities where laboratory diagnosis of
arboviruses is not always available. However, this guide may also be
very useful in hospitals that provide second- and third-level care, as it
describes the clinical manifestations of each of the three most important
arboviral diseases currently found in the Region, the elements for
differential diagnosis, and their clinical behavior.

About six to seven million people worldwide, mostly in Latin America, are estimated to be infected with
Trypanosoma cruzi, the parasite that causes Chagas disease (WHO data from 2021). Chagas disease is
found mainly in endemic areas of 21 Latin American countries. Chagas disease was once entirely

confined to rural areas but in the last decades, due to population movements, most infected people live
in urban settings and the disease has spread to other continents. The burden of disease is due to its
chronic progression with people still suffering years later after initial infection.

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.

Smallpox eradication was certified in 1980. Mpox has been endemic in Central and West African countries since it was first detected in 1958 . It is a zoonosis; cases are often found close to tropical rainforests where various animals carry the orthopoxvirus that causes the disease. In endemic countr...ies, most mpox infections in humans result from a primary animal-to-human transmission. Human-to-human transmission can result from close contact with respiratory secretions, skin lesions of an infected person, or recently contaminated objects. Transmission can also occur via the placenta from mother to fetus or through close contact during and after birth.

This is a case-ascertained prospective investigation of all identified health care contacts working in a health care facility in which a laboratory confirmed 2019-nCoV infected patient (see 2.2 Study population) receives care. Note that this study can be done in health care facilities at all 3 level...s of a health system – not just in hospitals. It is intended to provide epidemiological and serologic information which will inform the identification of risk factors 2019-nCoV infection among health care workers.
There are three primary objectives of this investigation among health care workers in a health care setting where a 2019-nCoV infected patient is being cared for:
To better understand the extent of human-to-human transmission among health care workers, by estimating the secondary infection rate1 for health care worker contacts at an individual level.
To characterize the range of clinical presentation of infection and the risk factors for infection among health care workers.
To evaluate effectiveness of infection prevention and control measures among health care workers
To evaluate effectiveness of infection prevention and control programmes at health facility and national level

The Zambia Population Based HIV impact assessment of 2016, reported the prevalence of viral hepatitis in Zambia as ranging between 5.6% among adults aged 15 to 59% in the general population, and 7.1% among HIV infected individuals. It is estimated that the majority of persons with chronic hepatitis ...B and/ or hepatitis C are unware of their infection and do not benefit from promotive, preventive and curative services designed to reduce onward transmission. Zambia introduced hepatitis B virus vaccine to the routine Under 5 vaccination schedule in 2005. Preliminary results from the ZAMPHIA indicate that hundreds of infections have been abated in children since then. However, its also clear that we continue to miss key opportunities to prevent transmission, diagnose and treat infections, prevent serious disease, and in many cases cure people. In addition, high risk groups inter alia health care workers still have limited access to the vaccine.

Soil-transmitted helminths are a group of intestinal worms that include Ascaris lumbricoides (giant roundworm), Trichuris trichiura (whipworm), and Ancylostoma spp. (A. duodenale, A. ceylanicum) and Necator americanus (hookworms). Despite the clear biological differences among the different species,... their transmission is characterized by the same sequence of events: (i) infected individuals excrete worm eggs through their stool in soil; (ii) under optimal conditions of moisture and temperature the excreted eggs develop into infectious stages; and (iii) finally, infection occurs through oral uptake (Ascaris, Ancylostoma and Trichuris) or skin penetration (Ancylostoma and Necator) of these infectious stages (embryonated eggs and third stage larvae) that reside in the soil and/or in the environment (referring to their common name).
