Approximately 350 million people (5%– 7% of the world's population) are chronically infected with the hepatitis B virus (HBV), and 600,000 (0.2%) die each year of HBV-related disease and hepatocellular carcinoma [1–3]. Sub-Saharan Africa and the Far East have high HBV endemicity (population prevalence, 18%); eastern and southern Europe, South America, and the rest of Africa and Asia have interm...
This paper presents the results of a comprehensive examination of current distribution of Hepatitis A virus (HAV) seroprevalence and endemicity in Turkey and the possible links between HAV endemicity and socioeconomic development. We performed a systematic search in online resources published between January 2000 and August 2015. The 22 provinces were able to be assigned a hepatitis A endemicit...
Rift Valley fever is an endemic vector-borne disease in West Africa, which mainly affects domestic ruminants and occasionally humans. The aetiological mechanisms of its endemicity remain under debate. We used a simple spatially explicit model to assess the possibility of endemicity without wild animals providing a permanent virus reservoir. Our model takes into account the vertical transmission...
Blastomycosis a potentially fatal fungal disease, is well known from defined areas of endemicity in Ontario, primarily in the northern part of the province. We present 2 unusual cases that appear to extend the area of endemicity into urban southern Ontario, specifically Toronto. Both patients presented to a dermatology clinic with skin lesions. Chest radiography, history and general physical ev...
We used multilocus PCR and electrospray ionization mass spectrometry (PCR/ESI-MS) to determine the genotype and drug resistance profiles for 96 Mycobacterium tuberculosis isolates circulating in regions of high and low tuberculosis (TB) endemicity in China. The dominant principal genetic group (PGG) circulating in China was PGG1, and drug-resistant gene mutations were more diversified in the re...
An epidemiological cross-sectional study was undertaken to determine the endemicity of malaria among the Orang Asli population of Raub, Pahang. Malaria endemicity was measured in terms of the prevalence of parasitaemia and splenomegaly. A total of 520 Orang Asli were examined. The point prevalence of malaria was 24.2% (95% CI 20.7-25.1), with Plasmodium falciparum (67.5%) being the predominant ...
INTRODUCTION A few older publications describe leprosy associated with pregnancy, a situation that has been linked to leprosy exacerbation. This study aimed to describe the detection rate of this association in the State of Pará by county and Integration Region (IR) from 2007 to 2009 via an analysis of socio demographic, epidemiological and operational indices. METHODS This was a descriptive ...
Hepatitis B virus (HBV) infection is a public health problem as a cause of liver diseases including hepatocellular carcinoma and cirrhosis. It is estimated that 350 million people live with chronic infection and about one million people die every year from complication of this chronic disease in the world. So far, ten HBV genotypes (A-J) has been identified which show a geographical distributio...
