The disease is also particularly dangerous for pregnant women and their fetuses during late pregnancy, as it may cause premature labor and fetal death. [ 37 ] [ 38 ] [ 39 ] A study done by the Centers for Disease Control (CDC) in Haiti found that in pregnant women who contracted the disease, 16% of 900 women had fetal death.
Cholera pandemics in the 19th and 20th centuries led to the growth of epidemiology as a science and in recent years it has continued to press advances in the concepts of disease ecology, basic membrane biology, and transmembrane signaling and in the use of scientific information and treatment design.
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
Symptoms of the disease appear between 12 hours and 5 days of infection; however, only 10% of infected people show severe symptoms of watery diarrhoea, vomiting and leg cramps. [8] Cholera is diagnosed through a stool test or rectal swab, and today treatment takes the form of an oral rehydration solution (ORS).
Medical microbiology, the large subset of microbiology that is applied to medicine, is a branch of medical science concerned with the prevention, diagnosis and treatment of infectious diseases. In addition, this field of science studies various clinical applications of microbes for the improvement of health.
A cholera vaccine is a vaccine that is effective at reducing the risk of contracting cholera. [10] The recommended cholera vaccines are administered orally to elicit local immune responses in the gut, where the intestinal cells produce antibodies against Vibrio cholerae, the bacteria responsible for the illness. This immune response was poorly ...
Chemical treatment with halogens—chlorine bleach, tincture of iodine, or commercial tablets—have low-to-moderate effectiveness against protozoa such as Giardia, but work well against bacteria and viruses. UV light is effective against both viruses and cellular organisms, but only works in clear water, and it is ineffective unless ...
An 1831 color lithograph by Robert Seymour depicts cholera as a robed, skeletal creature emanating a deadly black cloud.. The miasma theory (also called the miasmic theory) is an abandoned medical theory that held that diseases—such as cholera, chlamydia, or the Black Death—were caused by a miasma (μίασμα, Ancient Greek for 'pollution'), a noxious form of "bad air", also known as ...
