  Tropical Diseases
Tropical diseases are illnesses that either occur uniquely in tropical and subtropical regions (which is rare) or, more commonly, are either more widespread in the tropics or more difficult to prevent or control.
It is believed that diseased monkeys of Africa and tropical America are the primary source of infection and that carrier mosquitoes transmit the infection to humans.
The disease spread from its probable area of origin in the Indus Valley in India to the Mediterranean and North African regions; all of Europe was affected.

 Tropical disease - Wikipedia, the free encyclopedia
Tropical diseases are infectious diseases that either occur uniquely in tropical and subtropical regions (which is rare) or, more commonly, are either more widespread in the tropics or more difficult to prevent or control.
Some tropical diseases are very rare, but may occur in sudden epidemics, such as the Ebola hemorrhagic fever, Lassa fever and the Marburg virus.
Tropical countries like Brazil, which have improved their socio-economic situation and invested in hygiene, public health and the combat of transmissible diseases have achieved dramatic results in relation to the elimination or decrease of many endemic tropical diseases in their territory.

 ASTMH :: Questions & Answers : Tropical Diseases
Some of the organisms that cause tropical diseases are bacteria and viruses, terms that may be familiar to most people since these types of organisms cause illness common in the U.S. Less well known are those more complex organisms commonly referred to as parasites.
Malaria is caused by protozoa of genus Plasmodium.
Acute disease involves fever, swelling of the lymph nodes and, sometimes, inflammation of the heart muscle and of the brain.

Because some of these diseases show similar symptoms to a nasty case of the flu, the person is often able to spread the disease before they are aware of the fact that it is a tropical disease.
Very few tropical diseases can be prevented specifically by vaccination, so travellers to countries where diseases are prevalent are at an increased risk of picking up a disease against which they have no natural resistance.
Tropical diseases are a long way from being controlled or eradicated so it is imperative that travelers take precautions to protect themselves and others.

Although many of the tropical diseases this workshop will cover are diseases endemic to the tropical regions of Ecuador, this workshop will also have an overview of the history of epidemics in the region.
While these diseases are different in that they are carried into the area by outsiders as opposed to being common in the region, health care workers can learn a great deal about indigenous culture through their assessment of such epidemics.
Chagas’ Disease, which affects nearly 18 million people in the Americas, is a disease which is caused by bugs which live in and around the home, and pass the disease onto people.

 Marburg outbreak raises tropical disease profile
The Marburg virus disease, first identified in 1967 during simultaneous outbreaks affecting laboratory workers in Marburg and Frankfurt, Germany, and in Belgrade, in the former Yugoslavia, is an acute febrile illness accompanied by severe hemorrhagic manifestations.
The impact of tropical diseases is heightened by the significant lack of resources and infrastructure necessary to deliver general medical care in many developing countries.
Undoubtedly, awareness of the seriousness of tropical diseases, previously thought to be of low priority, has risen in recent years, and this latest outbreak serves as an effective reminder.

 Fish Health and Disease
Remember that disease organisms will always be present in the aquarium to some extent, but they will not normally affect a healthy fish.
Diseases take hold when fish are injured or weakened by stress, which may be caused by poor water quality, aggressive tankmates or simply the transportation and handling involved in acquiring new fish.
Introducing new fish to an established aquarium is a potential source of new disease organisms, to which the current inhabitants may have no resistance.

In areas of Africa where the disease is endemic (that is, constantly present), Lassa fever is a significant cause of morbidity and mortality.

 NIH Guide: TROPICAL DISEASE RESEARCH UNITS
RESEARCH OBJECTIVES Background Parasitic diseases continue to represent tremendous public health problems, especially for people living in the tropics where parasites are responsible for deaths and impaired growth and development of children and debilitating, chronic diseases among adults.
Currently, the parasitology and tropical disease program in the DMID, NIAID, consists primarily of investigator initiated research project grants focusing on the biology (molecular and cellular biology, immunology, and biochemistry) of the medically important protozoa and helminths as well as the invertebrate vectors.
For the purpose of this RFA, intervention strategies to be considered are: (1) vaccines to prevent infection and/or disease; (2) chemotherapeutic agents to prevent and/or treat infection; and (3) methods to control invertebrate vectors or interrupt the parasite's life cycle in the vector.

Of special interest to clinicians and public health workers in developed nations is the occurrence of severe parasitic disease in individuals who acquired their infection congenitally or as a result of immunosuppression.
The International Centers for Tropical Disease Research (ICTDR) network serves to coordinate many of the Institute's activities in the area of tropical infectious diseases.

It is a viral disease which affects select groups of fish such as cichlids, but does not affect cyprinids or catfish.
Adverse water conditions are the biggest predisposing factor to this disease followed by stress which can cause what may have been a dormant form of the virus to become active.
This disease also can be found in fish which have been artificially coloured or dyed, but it is not known if the reason for this is because of the techniques and equipment used for the colouring procedure on sick fish contaminating healthy fish, or from the stress response of the colouring itself.

 eMedicine - Endomyocardial Fibrosis : Article by James L Furgerson, MD
Tropical EMF and Löffler endocarditis should be distinguished from endocardial fibroelastosis, which is characterized by cartilaginous thickening of the mural endocardium, chiefly of the left ventricle.
This disease is most common in the first 2 years of life and, in some patients, appears to be an inherited disorder that is associated with congenital cardiac malformations.
The eosinophil is not present as frequently in cases of tropical EMF as in Löffler endocarditis; thus, the role of the eosinophil in the tropical disease is likely less significant.
