In 1979 an outbreak of hepatoenteritis, also known as the Palm Island mystery disease, was reported and described a hepatitis-like illness (associated in many cases with dehydration and bloody diarrhoea) in 148 people (138 children and 10 adults) of Aboriginal and Torres Strait Islander descent in Palm Island, Queensland.

Symptoms of hepatoenteritis included diarrhoea, vomiting attacks, loss of balance and disorientation.

The perinatal effects of cyanobacteria contamination of drinking water include prematurity, low birth weight and congenital defects detected at birth. In 1996 there were 63 deaths attributed to drinking water contamination in Caruaru, Brazil.

The presence of avian botulism is extremely hard to detect before an outbreak. Frequent surveillance of sites at risk is needed for early detection of the disease in order to take action and remove carcasses. Vaccines are also developed, but they are expected to have limited effectiveness in stemming outbreaks in wild waterbird populations. However may be effective in reducing mortality for endangered island waterfowl and small non-migratory wild populations. Field tests are needed.

The diagnosis by symptoms is not reliable enough so it’s better to do a molecular diagnosis based in test samples. Some of these methods (like Dot-blot hybridisation) allow the scientists to detect the viroid even six months before noticing the first symptoms.

The first step is the purification to obtain the nucleic acids of the plant cells. The leaves of the plant located four or more below the spare leaf are cut. Afterwards, they are blended (homogenize) with sodium sulfite. Then the extract is filtered and clarified by centrifugation (10.000 g during 10 minutes). The next step is to add polyethylene glycol (PEG). Finally, after nearly two hours of incubation at 4 °C, and after another centrifugation (at low speed) the nucleic acids can be extracted by chloroform procedures, for example.

When approximately 1 g of coconut tissue has been purified, the electrophoresis method can be started, which will help to identify the viroid by its relative mobility. The CCCVd is analysed in one or two dimensional polyacrylamide gels with a silver stain.

The viroid can also be detected by a more sensitive method called dot blot molecular hybridization. In this method CCCVd is amplified by the PCR (polymerase chain reaction) and the clones of CCCVd are used as templates to synthesize a complementary DNA or RNA chain. These sequences are radioactively labelled so when they are put over the samples with the intention to analyse (on a supporting membrane) and exposed to x-ray film, then if CCCVd is present it will appear as a dark colour. This dark tonality only appears when nucleic acid hybridisation occurs.

Only specialized laboratories can adequately diagnose "Babesia" infection in humans, so "Babesia" infections are considered highly under-reported. It develops in patients who live in or travel to an endemic area or receive a contaminated blood transfusion within the preceding 9 weeks, so this aspect of the medical history is vital. Babesiosis may be suspected when a person with such an exposure history develops persistent fevers and hemolytic anemia. The definitive diagnostic test is the identification of parasites on a Giemsa-stained thin-film blood smear.

So-called "Maltese cross formations" on the blood film are diagnostic (pathognomonic) of babesiosis, since they are not seen in malaria, the primary differential diagnosis. Careful examination of multiple smears may be necessary, since "Babesia" may infect less than 1% of circulating red blood cells, thus be easily overlooked.

Serologic testing for antibodies against "Babesia" (both IgG and IgM) can detect low-level infection in cases with a high clinical suspicion, but negative blood film examinations. Serology is also useful for differentiating babesiosis from malaria in cases where people are at risk for both infections. Since detectable antibody responses require about a week after infection to develop, serologic testing may be falsely negative early in the disease course.

A polymerase chain reaction (PCR) test has been developed for the detection of "Babesia" from the peripheral blood. PCR may be at least as sensitive and specific as blood-film examination in diagnosing babesiosis, though it is also significantly more expensive. Most often, PCR testing is used in conjunction with blood film examination and possibly serologic testing.

Other laboratory findings include decreased numbers of red blood cells and platelets on complete blood count.

In animals, babesiosis is suspected by observation of clinical signs (hemoglobinuria and anemia) in animals in endemic areas. Diagnosis is confirmed by observation of merozoites on thin film blood smear examined at maximum magnification under oil using Romonovski stains (methylene blue and eosin). This is a routine part of the veterinary examination of dogs and ruminants in regions where babesiosis is endemic.

"Babesia canis" and "B. bigemina" are "large "Babesia" species" that form paired merozoites in the erythrocytes, commonly described as resembling "two pears hanging together", rather than the "Maltese cross" of the "small "Babesia" species". Their merozoites are around twice the size of small ones.

Cerebral babesiosis is suspected "in vivo" when neurological signs (often severe) are seen in cattle that are positive for "B. bovis" on blood smear, but this has yet to be proven scientifically. Outspoken red discoloration of the grey matter "post mortem" further strengthens suspicion of cerebral babesiosis. Diagnosis is confirmed "post mortem" by observation of "Babesia"-infected erythrocytes sludged in the cerebral cortical capillaries in a brain smear.

The botulinum neurotoxin is lethal because it causes paralysis. Field identification involves locating birds showing flaccidity in the legs, wings and neck, as well as the presence of protuberant nictitating membrane. The presence of several dozen, or even hundreds, of fresh waterbird carcasses is the stereotypical sign an outbreak has occurred. In this case the specimens need to be taken to disease laboratory to determine the cause of mortality. Most commonly, detection of "C. botulinum" in carcasses during lab work is accomplished through analysis of polymerase chain reactions (PCR) and is often the most successful method.

During the latest outbreak of the disease (2004), several treatment methods were tested. Main treatment involved the administration of antibiotics, in some cases glucose solution or dietary mixtures were additionally supplemented. Outcome of the different treatment methods varied greatly. Especially the success of antibiotic treatment and a widespread use on wild animals remains a matter of debate.

Jembrana disease is an acute viral disease of cattle. While it produces relatively mild symptoms in taurine cattle, the Jembrana virus is particularly severe in Bali cattle where it has a fatality rate of approximately seventeen percent. Its first documented outbreak occurred in 1964 in the Jembrana district of Bali, Indonesia. Within two years of its appearance the disease had killed an estimated 26,000 of the approximately 300,000 cattle on Bali Island. The virus belongs to the Lentivirus genus, which include immunodeficiency viruses such as HIV. Instead of the chronic disease produced by most Lentivruses, Jembrana disease produces acute effects. After an incubation period of 5–12 days the disease produces symptoms including loss of appetite, fever, lethargy, enlargement of the lymph nodes, and diarrhea. There is at least one strain that has been sequenced.

Coconut cadang-cadang disease has no treatment yet. However, chemotherapy with antibiotics has been tried with tetracycline solutions; antibiotics failed trying to alter progress of the disease since they had no significant effect on any of the studied parameters. When the treated plants were at the early stage, tetracycline injections failed to prevent the progression of the palms to more advanced stages, nor did they affect significantly the mean number of spathes or nuts. Penicillin treatment had no apparent improvement either.

Control strategies are elimination of reservoir species, vector control, mild strain protection and breeding for host resistance. Eradication of diseased plants is usually performed to minimize spread but is of dubious efficacy due to the difficulties of early diagnosis as the virus etiology remains unknown and the one discovered are the three main stages in the disease development.

Coxsackie B virus is spread by contact and epidemics usually occur during warm weather in temperate regions and at any time in the tropics.

Treatment of asymptomatic carriers should be considered if parasites are still detected after 3 months. In mild-to-moderate babesiosis, the treatment of choice is a combination of atovaquone and azithromycin. This regimen is preferred to clindamycin and quinine because side effects are fewer. The standard course is 7 to 10 days, but this is extended to at least 6 weeks in people with relapsing disease. Even mild cases are recommended to be treated to decrease the chance of inadvertently transmitting the infection by donating blood. In life-threatening cases, exchange transfusion is performed. In this procedure, the infected red blood cells are removed and replaced with uninfected ones.

Imizol is a drug used for treatment of babesiosis in dogs.

Extracts of the poisonous, bulbous plant "Boophone disticha" are used in the folk medicine of South Africa to treat equine babesiosis. "B. disticha" is a member of the daffodil family Amaryllidaceae and has also been used in preparations employed as arrow poisons, hallucinogens, and in embalming. The plant is rich in alkaloids, some of which display an action similar to that of scopolamine.

The illness lasts about a week and is rarely fatal. Treatment includes the administration of nonsteroidal anti-inflammatory agents or the application of heat to the affected muscles. Relapses during the weeks following the initial episode are a characteristic feature of this disease.

There is no vaccine for SARS to date. Isolation and quarantine remain the most effective means to prevent the spread of SARS. Other preventative measures include:

- Handwashing

- Disinfection of surfaces for fomites

- Wearing a surgical mask

- Avoiding contact with bodily fluids

- Washing the personal items of someone with SARS in hot, soapy water (eating utensils, dishes, bedding, etc.)

- Keeping children with symptoms home from school

Many public health interventions were taken to help control the spread of the disease; which is mainly spread through respiratory droplets in the air. These interventions included earlier detection of the disease, isolation of people who are infected, droplet and contact precautions, and the use of personal protective equipment (PPE); including masks and isolation gowns. A screening process was also put in place at airports to monitor air travel to and from affected countries. Although no cases have been identified since 2004, the CDC is still working to make federal and local rapid response guidelines and recommendations in the event of a reappearance of the virus.

In cases of suspected copper poisoning, penicillamine is the drug of choice, and dimercaprol, a heavy metal chelating agent, is often administered. Vinegar is not recommended to be given, as it assists in solubilizing insoluble copper salts. The inflammatory symptoms are to be treated on general principles, as are the nervous ones.

There is some evidence that alpha-lipoic acid (ALA) may work as a milder chelator of tissue-bound copper. Alpha lipoic acid is also being researched for chelating other heavy metals, such as mercury.

Antibiotics are ineffective, as SARS is a viral disease. Treatment of SARS is largely supportive with antipyretics, supplemental oxygen and mechanical ventilation as needed.

People with SARS must be isolated, preferably in negative pressure rooms, with complete barrier nursing precautions taken for any necessary contact with these patients.

Some of the more serious damage caused by SARS may be due to the body's own immune system reacting in what is known as cytokine storm.

As of 2017, there is no cure or protective vaccine for SARS that has been shown to be both safe and effective in humans. The identification and development of novel vaccines and medicines to treat SARS is a priority for governments and public health agencies around the world. MassBiologics, a non-profit organization engaged in the discovery, development and manufacturing of biologic therapies, is cooperating with researchers at NIH and the CDC developed a monoclonal antibody therapy that demonstrated efficacy in animal models.

There is no known treatment for FTS, as the cause is not yet known. There are conflicting reports on whether the paralysis is reversible; some sources claim that moving an elephant away from the area in which it contracted the condition will allow it to recover, while others claim that damage to the trunk is irreversible.

In some extreme cases, wildlife managers have killed affected elephants for humane reasons.

Cookware in which copper is the main structural element (as opposed to copper clad, copper sandwiched or copper colored) is sometimes manufactured without a lining when intended to be used for any of a number of specific culinary tasks, such as preparing preserves or meringues. Otherwise, copper cookware is lined with a non-reactive metal to prevent contact between acidic foods and the structural copper element of the cookware.

Excepting for acute or chronic conditions, exposure to copper in cooking is generally considered harmless. Following Paracelsus, dosage makes the poison; as this pertains to copper "a defense mechanism has apparently evolved as a consequence of which toxicity in man is very unusual."

Acute exposure and attendant copper toxicity is possible when cooking or storing highly acidic foods in unlined copper vessels for extended periods, or by exposing foodstuffs to reactive copper salts (copper corrosion, or verdigris). Continuous, small ("chronic") exposures of acidic foods to copper may also result in toxicity in cases where either surface area interaction potentials are significant, pH is exceptionally low and concentrated (in the case of cooking with, for example, vinegar or wine), or both, and insufficient time elapses between exposures for normal homeostatic elimination of excess copper.

Exceptions to the above may be observed in the case of jam, jelly and preserve -making, wherein unlined copper vessels are used to cook (not to store) acidic preparations, in this case of fruit. Methods of jamming and preserving specify sugar as chemically necessary to the preserving (antibacterial) action, which has the additional effect of mediating (buffering) the interaction of fruit acid with copper, permitting the use of the metal for its efficient thermal transfer properties.

Diphtheritic stomatitis is a recently discovered disease and has thus far been reported only in Yellow-eyed penguins ("Megadyptes antipodes"). Its symptoms are similar to human diphtheria and is characterized by infecteous lesions in the mouth area that impede swallowing and cause respiratory troubles. The infection is caused by "Corynebacterium amycolatum", an aerobic Gram-positive bacterium and mainly affects very young chicks. However, it seems likely that a triggering agent (e.g. a virus) might be involved in which renders the corynebacterium a secondary pathogen.

The disease has been a serious cause of mortality in the 2002 and 2004 Yellow-eyed penguin breeding seasons. It seems that only the New Zealand South Island and Stewart Island/Rakiura were affected.

Ichthyoallyeinotoxism, or hallucinogenic fish inebriation, comes from eating certain species of fish found in several parts of the tropics, the effects of which are reputed to be similar in some aspects to LSD. Experiences may include vivid auditory and visual hallucinations. This has given rise to the collective common name "dream fish" for ichthyoallyeinotoxic fish.

The species most commonly claimed to be capable of producing this kind of toxicity include several species from the "Kyphosus" genus, including "Kyphosus fuscus", "K. cinerascens" and "K. vaigiensis". It is unclear whether the toxins are produced by the fish themselves or by marine algae in their diet, but a dietary origin may be more likely.

"Sarpa salpa", a species of bream, can induce LSD-like hallucinations if it is eaten. These widely distributed coastal fish are called "the fish that make dreams" in Arabic. In 2006, two men who ate fish, apparently the "Sarpa salpa" caught in the Mediterranean were affected by ichthyoallyeinotoxism and experienced hallucinations lasting for several days.

Other hallucinogenic fish are "Siganus spinus", called "the fish that inebriates" in Reunion Island, and "Mulloides flavolineatus" (formerly "Mulloidichthys samoensis"), called "the chief of ghosts" in Hawaii.

Flinders Island spotted fever is a condition characterized by a rash in approximately 85% of cases.

It is associated with "Rickettsia honei".

Taravana is a disease often found among Polynesian island natives who habitually dive deep without breathing apparatus many times in close succession, usually for food or pearls. These free-divers may make 40 to 60 dives a day, each of 30 or 40 metres (100 to 140 feet).

Taravana seems to be decompression sickness. The usual symptoms are vertigo, nausea, lethargy, paralysis and death. The word "taravana" is Tuamotu Polynesian for "to fall crazily".

Taravana is also used to describe someone who is "crazy because of the sea".

Avian malaria is a parasitic disease of birds, caused by parasite species belonging to the genera "Plasmodium" and "Hemoproteus" (phylum Apicomplexa, class Haemosporidia, family Plasmoiidae). The disease is transmitted by a dipteran vector including mosquitoes in the case of "Plasmodium" parasites and biting midges for "Hemoproteus." The range of symptoms and effects of the parasite on its bird hosts is very wide, from asymptomatic cases to drastic population declines due to the disease, as is the case of the Hawaiian honeycreepers. The diversity of parasites is large, as it is estimated that there are approximately as many parasites as there are species of hosts. Co-speciation and host switching events have contributed to the broad range of hosts that these parasites can infect, causing avian malaria to be a widespread global disease, found everywhere except Antarctica.

Lucio Godina (March 8, 1908 – November 24, 1936) and Simplicio Godina (March 8, 1908 - December 8, 1936) were pygopagus conjoined twins from the island of Samar in the Philippines.

At the age of 21 they married Natividad and Victorina Matos, who were identical twins. They performed in various sideshow acts, including in an orchestra on Coney Island and in dance with their wives.

After Lucio died of rheumatic fever in New York City, doctors operated to separate him from Simplicio. Simplicio survived the operation, but died shortly thereafter due to spinal meningitis.

Avian malaria is most notably caused by Plasmodium relictum, a protist that infects birds in all parts of the world apart from Antarctica. There are several other species of "Plasmodium" that infect birds, such as "Plasmodium anasum" and "Plasmodium gallinaceum", but these are of less importance except, in occasional cases, for the poultry industry. The disease is found worldwide, with important exceptions. Usually, it does not kill birds. However, in areas where avian malaria is newly introduced, such as the islands of Hawaiʻi, it can be devastating to birds that have lost evolutionary resistance over time.

FTS has been observed in the northwest of Zimbabwe, the Satara area of Kruger National Park, and Fothergill in Lake Kariba. The syndrome has only been observed in free-ranging elephants specifically "Loxodonta africana", and primarily affects older male elephants. Over thirty elephants were observed to be afflicted with this paralysis, including at least eight in Kruger National Park and twelve cases near Fothergill Island.
