Without treatment, the disease is invariably fatal, with progressive mental deterioration leading to coma, systemic organ failure, and death. An untreated infection with T. b. rhodesiense will cause death within months [17] whereas an untreated infection with T. b. gambiense will cause death after several years. [18]
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
Widespread non-communicable diseases such as cardiovascular disease and cancer are not included. An epidemic is the rapid spread of disease to a large number of people in a given population within a short period of time; in meningococcal infections , an attack rate in excess of 15 cases per 100,000 people for two consecutive weeks is considered ...
This is a list of countries by risk of premature death from non-communicable disease such as cardiovascular disease, cancer, diabetes, or chronic respiratory disease between ages 30 and 70 as published by the World Health Organization in 2008. Measuring the risk of dying from target NCDs is important to assess the extent of burden from ...
For example, various Global Burden of Disease Studies investigate such factors and quantify recent developments – one such systematic analysis analyzed the (non)progress on cancer and its causes during the 2010–19-decade, indicating that 2019, ~44% of all cancer deaths – or ~4.5 M deaths or ~105 million lost disability-adjusted life years ...
The plague is considered the likely cause of the Black Death that swept through Asia, Europe, and Africa in the 14th century and killed an estimated 50 million people, [1] [10] including about 25% to 60% of the European population. [1] [11] Because the plague killed so many of the working population, wages rose due to the demand for labor. [11]
Two individuals in the southern Ashanti Region of Ghana developed Marburg disease-like symptoms—including diarrhea, fever, nausea, and emesis—before dying in a hospital. [1] [8] The two victims were unrelated. [8] Tests for Marburg virus conducted in Ghana were positive for both. This was revealed on 8 July 2022. [1]
