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.
In 2015, about 60,800 people had mesothelioma, and 32,000 died from the disease. [8] [9] Rates of mesothelioma vary in different areas of the world. [3] Rates are higher in Australia, the United Kingdom, and lower in Japan. [3] It occurs in about 3,000 people per year in the United States. [14] It occurs more often in males than females. [3]
In a small study of 26 decedents, [better source needed] the pandemized COVID-19 and infection-related disease were "major contributors" to patients' death. [12] Such deaths are sometimes evaluated via excess deaths per capita – the COVID-19 pandemic deaths between January 1, 2020, and December 31, 2021, are estimated to be ~18.2 million ...
Usually no symptoms shown but if exposure is extensive, it can cause lung impairment. Pneumothorax: Some reports have also linked the condition of pneumothorax to asbestos related diseases. Malignant mesothelioma: an aggressive and incurable tumour arising from mesothelial cells of the pleura (the lining of the thoracic cavity).
Mesothelioma appears from 20 to 50 years after the initial exposure to asbestos. The symptoms include shortness of breath, chronic chest pain, cough, and weight loss. Diagnosing mesothelioma is often difficult and can include physical examination, chest X-ray and lung function tests, followed by CT scan and MRI. A biopsy is needed to confirm a ...

Unlike a disease's mortality rate, the CFR does not take into account the time period between disease onset and death. A CFR is generally expressed as a percentage. It is a measure of disease lethality, and thus may change with different treatments. [1] CFRs are most often used for with discrete, limited-time courses, such as acute infections.
Deaths from cancer were 5.8 million in 1990. [212] Deaths have been increasing primarily due to longer lifespans and lifestyle changes in the developing world. [25] The most significant risk factor for developing cancer is age. [213] Although it is possible for cancer to strike at any age, most patients with invasive cancer are over 65. [213]
