Emergent Human Diseases Are Considered as Either

Emergent human diseases are considered as either new kinds of pathogens or old pathogens that have changed to become novel just like flu does on an annual basis. Generally, diseases have usually originated from wildlife and woods and penetrated into human populations such as malaria and plague. In last five decades, emerging human diseases have quadrupled mainly because of the increasing human encroachment into habit. These trends have specifically been worse in areas that are considered as disease hot spots across the globe, particularly in tropical regions. Notably, the potential for a severe outbreak in large populations is huge because of the modern air travel and enormous market in wildlife trafficking. As a result, the key to predicting and preventing the next pandemic is understanding the protective effects of nature intact as stated by experts.

An example of an emergent human disease and infectious disease is Hendra virus in Australia, which is closely related to Nipah virus in South Asia. While the virus originated with Pteropus vampyrus or flying boxes, its main cause is the disruption of the ecosystem. Hendra and Nipah viruses are closely linked in terms of henipah virus and originated with fruit bats, which are messy eaters. These bats usually hang upside down similar to Dracula that are bound tightly in their membranous wings as they eat fruit by chewing the pulp and then coughing up the seeds and juices (Robbins, 2012).

Once the virus breaks out from the fruit bats and into species that have not evolved with it, there is a likelihood of the occurrence of a horror show. For instance, in 1999 in rural Malaysia, it's possible that a bat dropped a piece of masticated fruit into a piggery in a forest. Consequently, the pigs got infected with the virus and amplified it before transmission into humans, which was startling in its lethality. Since there is no cure or vaccine for the virus, approximately 50% of the infected people died many suffered crippling and permanent neurological disorders. Generally, if henipah viruses evolve to be transmitted eagerly through casual contact, there are concerns that it could spread even rapidly and widely even throughout the world.

As noted in the past four decades, any emergent human disease and ecological infectious disease is usually caused by demographical changes and encroachment into wild lands. The failure to take care of the natural world can generally contribute to breakdown of the ecosystems that in turn result in emerging and ecological infectious diseases. The developing model of infectious diseases like SARS and Ebola that have taken place in the past several decades is because of the things people do to nature. Therefore, as it turns out, disease can largely be regarded as an environmental issue since 60% of emerging human and ecological infectious diseases originate in animals, especially wildlife. Consequently, several teams of conservation biologists and veterinarians are involved in global initiatives medical doctors, other clinical professionals, and epidemiologists to understand the ecology of disease.
