Urogenital schistosomiasis is a common neglected tropical disease in many rural communities in African countries, with patches of infection in the Eastern Mediterranean Region. Globally, an estimate...d 239 million people are currently infected, with burden estimated at more than 3.5 million disability-adjusted life years (DALYs). In many endemic areas, severely infected individuals may suffer fibrosis of the bladder, kidney damage, bladder cancer, and death if untreated. This, however, depends on several factors such as host-parasite genetics, degree and length of exposure, intensity of infection, host immune response to the parasites, and coinfections with other tropical diseases such as malaria and HIV-1.

Rabies is a devastating and societally important zoonotic disease, which is transmitted principally to humans through the bite of infected dogs. This acute, progressive viral encephalitis has the hi...ghest case fatality of any infectious disease and kills tens of thousands of people annually, with children and impoverished communities being affected disproportionately.

A wide spectrum of disease severity has been described for Human African Trypanosomiasis (HAT) due to
Trypanosoma brucei rhodesiense (T.b. rhodesiense), ranging from chronic ...-to-highlight medbox">disease patterns in southern countries of East Africa to an increase in virulence towards the north. However, only limited data on the clinical presentation of T.b. rhodesiense HAT is available. From 2006-2009 we conducted the first clinical trial program (I MPAMEL III) in T.b. rhodesiense endemic areas of
Tanzania and Uganda in accordance with international standards (ICH-GCP). The primary and secondary outcome measures were safety and efficacy of an abridged melarsoprol schedule for treatment of second stage disease. Based on diagnostic findings and clinical examinations at baseline we describe the clinical presentation of T.b. rhodesiense HAT in second stage patients from two distinct geographical settings in East Africa.

Technical package for cardiovascular disease management in primary health care.
The new treatment recommendations that extend the 2018 treat all recommendation for adults with chronic HCV infection to include adolescents and children down to 3 years, and to align the existing recommended pangenotypic direct-acting antiviral (DAA) regimens (SOF/DCV, SOF/VEL and G/P) for adults, ...to those for adolescents and children. This alignment is expected to simplify procurement, promote access to treatment among children in low- and middle-income countries and contribute to global efforts to eliminate the disease

Onchocerciasis causes skin and eye disease, visual impairment and neurological problems. It is mostly found in Africa, but also in Latin America and Yemen. The common name, ‘river blindness,’ gives a good indication where the ...ute-to-highlight medbox">disease can be found: the vector of the parasite, a small black fly of the Simulium species, breeds in rivers where there is turbulence in the water, such as rapids, or where the flow is disturbed by overhanging vegetation.

Cystic fibrosis (CF) was earlier thought to be a disease prevalent in the West among Caucasians. However, quite a number of recent studies have uncovered CF cases outside ...highlight medbox">of this region, and reported hundreds of unique and novel variant forms of CFTR. Here, we discuss the evidence of CF in parts of the world earlier considered to be rare; Africa, and Asia. This review also highlighted the CFTR mutation variations and new mutations discovered in these regions. This discovery implies that the CF data from these regions were earlier underestimated. The inadequate awareness of the disease in these regions might have contributed towards the poor diagnostic facilities, under-diagnosis or/and under-reporting, and the lack of CF associated health policies. Overall, these regions have a high rate of infant, childhood and early adulthood mortality due to CF. Therefore, there is a need for a thorough investigation of CF prevalence and to identify unique and novel variant mutations within these regions in order to formulate intervention plans, create awareness, develop mutation specific screening kits and therapies to keep CF mortality at bay.

The cardiovascular disease continuum begins with risk factors such as diabetes mellitus (DM), progresses to vasculopathy and myocardial dysfunction, and finally ends with cardiovascular death. Diabetes is associated with a 2- to 4-fold increased ris...k for heart failure (HF). Moreover, HF patients with DM have a worse prognosis than those without DM. Diabetes can cause myocardial ischemia via micro- and macrovasculopathy and can directly exert deleterious effects on the myocardium. Hyperglycemia, hyperinsulinemia, and insulin resistance can cause alterations in vascular homeostasis. Then, reduced nitric oxide and increased reactive oxygen species levels favor inflammation leading to atherothrombotic progression and myocardial dysfunction. The classification, diagnosis, and treatment of HF for a patient with and without DM remain the same. Until now, drugs targeting neurohumoral and metabolic pathways improved mortality and morbidity in HF with reduced ejection fraction (HFrEF). Therefore, all HFrEF patients should receive guideline-directed medical therapy. By contrast, drugs modulating neurohumoral activity did not improve survival in HF with preserved ejection fraction (HFpEF) patients. Trials investigating whether sodium-glucose cotransporter-2 inhibitors are effective in HFpEF are on-going. This review will summarize the epidemiology, pathophysiology, and treatment of HF in diabetes.

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 coronavirus disease 2019 (COVID-19) pandemic has created a global and gendered crisis that is compounding existing inequalities and disproportionately affecting girls and women. Emerging evidence from the COVID-19 crisis in 2020 shows school clo...sures, disruptions in essential services and rising poverty contributed to girls’ increased risk of female genital mutilation (FGM). School closures limited the monitoring and reporting of cases of FGM. Rising household monetary poverty may have contributed to families adopting negative coping mechanisms, including having girls undergo FGM as a precursor to marriage to reduce household costs. A report from the United Nations Population Fund (UNFPA) estimates 2 million additional cases of FGM by 2030 due to the pandemic.

Rreport of a WHO Consultative Meeting Kolkata India 2012
Specific measures are being taken within the National Tuberculosis Control Programme (NTP) to address the MDR TB problem through appropriate management of patients and strategies to prevent the prop...agation and dissemination of MDR TB.
The term "Programmatic Management of Drug Resistant TB" (PMDT) refers to programme based MDR TB diagnosis, management and treatment. This guideline promotes full integration of basic TB control and PMDT activities under the NTP, so that patients with TB are evaluated for drug resistance and are placed on the appropriate treatment regimen and properly managed from the outset of treatment, or as early as possible. The guidelines also integrate the identification and treatment of more severe forms of drug resistance, such as extensively drug resistant TB (XDR TB).
At the end, the guideline introduces new standards for registering, monitoring and reporting outcomes of multidrug resistant TB cases.

Lymphatic filariasis is a neglected tropical disease that can cause permanent disability through disruption of the lymphatic system. This disease i...s caused by parasitic filarial worms that are transmitted by mosquitos. Mass drug administration (MDA) of antihelmintics is recommended by WHO to eliminate lymphatic filariasis as a public health problem. This study aims to produce the first geospatial estimates of the global prevalence of lymphatic filariasis infection over time, to quantify progress towards elimination, and to identify geographical variation in distribution of infection.
