Exposure to high levels of dioxins in humans causes a severe form of persistent acne, known as chloracne. [34] High occupational or accidental levels of exposures to dioxins have been shown by epidemiological studies to lead to an increased risk of tumors at all sites. [35] Other effects in humans (at high dose levels) may include:
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.
For a given epidemic or pandemic, the average of its estimated death toll range is used for ranking. If the death toll averages of two or more epidemics or pandemics are equal, then the smaller the range, the higher the rank. For the historical records of major changes in the world population, see world population. [3]
Pinpoint pupils, or miosis, caused by opioids. Because of their effect on the part of the brain that regulates breathing, opioids can cause very slow or stopped breathing, during overdoses, leading to hypoxia [16] or death if left untreated. [1] Hypoxia is typically caused by respiratory depression.

Alcohol can exacerbate the symptoms and may directly contribute to increased severity of symptoms. The reasons for toxicity vary depending on the mixture of drugs. Usually, most victims die after using two or more drugs in combination that suppress breathing, and the low blood oxygen level causes brain death.
