Disability-adjusted life year for childhood-cluster diseases per 100,000 inhabitants. These include pertussis , poliomyelitis , diphtheria , measles , and tetanus . no data
Pathogenic bacteria are also the cause of high infant mortality rates in developing countries. [5] A GBD study estimated the global death rates from (33) bacterial pathogens, finding such infections contributed to one in 8 deaths (or ~7.7 million deaths), which could make it the second largest cause of death globally in 2019.

Vibrio cholerae bacteria are transmitted through contaminated water. [10] Once ingested, the bacteria colonize the intestinal tract of the host and produce a toxin which causes body fluids to flow across the lining of the intestine. Death can result in 2–3 hours from dehydration if no treatment is provided. [11]
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.
Nutrition and growth during the early years of life can be related to the growth of diseases in humans later in their lives. For example, a study done in Jamaica showed that the blood pressure of children was associated with the mother's hemoglobin levels and body fat during pregnancy. [20]
Smallpox was an infectious disease caused by variola virus (often called smallpox virus), which belongs to the genus Orthopoxvirus. [7] [11] The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, [10] making smallpox the only human disease to have been eradicated to date.
In older children and adults the normal intestinal bacteria suppress development of C. botulinum. [ 52 ] While commercially canned goods are required to undergo a "botulinum cook" in a pressure cooker at 121 °C (250 °F) for 3 minutes, [ citation needed ] and thus rarely cause botulism, there have been notable exceptions.
Diagnostic methods that can identify influenza include viral cultures, antibody- and antigen-detecting tests, and nucleic acid-based tests. Treatment of influenza in cases of mild or moderate illness is supportive and includes anti-fever medications such as acetaminophen and ibuprofen , adequate fluid intake to avoid dehydration, and resting at ...
