The impact of veterinary medicine on the health of man and animals.

The impact of veterinary medicine on the health of man and animals cannot be underestimated as its known that 65% of infectious diseases in man stem from animals. The increased interaction between man and and animals has presented a platform for cross infection as in zoonotic diseases. The good-news about this is that since they share common causative agents ,research into prevention and treatment are often carried out using animal models which will eventually translate to use in man after clinical trials. e.g Dogs develop cancers with many similar characteristics to human cancers hence animal studies/trials are advancing management protocols.see The one health approach to diagnosis and treatment is borne out of the understanding that animal health is human health as such the National Institutes of Health just awarded a $1.5 million grant—to a veterinary lab. to find a cure for a bacterial infection that kills 30,000 Americans annually. Scientists at North Carolina State University's College of Veterinary Medicine will use that funding to study how the Clostridium difficile bacteria affects animals, with the hope that what they discover will apply to humans, too. That's the nature of medical progress—where insights gleaned from research in one species apply to others, including humans. Holistic approaches to health—ones that take into account human, animal and ecosystem health—could be the key to understanding and eventually defeating the diseases of the our modern age. Many diseases are transmitted from animals to humans. Mosquitoes carry Zika, malaria and West Nile virus. The Ebola outbreak that reached U.S. shores in 2014 was traced back to a diseased bat. Up to 60,000 Americans get rabies vaccinations each year after coming in contact with potentially rabid animals. The Centers for Disease Control and Prevention estimates that over 75 percent of infectious diseases originate in animals. Studying and treating diseases in animals often leads to advances in human medicine. One gene therapy for blindness in dogs proved so promising that researchers are now testing it on people. Veterinarians have discovered a protein that helps animals' broken bones heal quicker—and it works for humans, too. By studying the animals that transmit these diseases, health professionals can prevent epidemics. Consider the University of Pennsylvania veterinary school's "geographic information system," which monitors chicken populations for avian flu. The system helped identify and contain an avian flu outbreak in Pennsylvania before it could spread to other flocks—or humans. Losses totaled just $400,000. By contrast, an outbreak in Virginia led to $100 million in damages—and risked giving the disease time to mutate and infect people—because such surveillance technology wasn't employed.Mammals and humans also suffer from some of the same non-communicable diseases. Horses, for example, can develop cardiovascular disease. Dogs develop cancers with many similar characteristics to human cancers.Studying and treating diseases in animals often leads to advances in human medicine. Studying animals can even help us diagnose disease in humans. For example, dogs can smell cancerous masses. Doctors and engineers are now exploring whether it's feasible to develop an electronic system that can mimic dogs' sense of smell in order to accurately and efficiently diagnose cancer in patients. Given the links between human and animal health, it makes sense to tear down the walls between human and veterinary medicine. Some universities are doing just that.Tufts University offers a joint doctor of veterinary medicine/master of public health degree. During their first summer, students spend eight weeks in the field volunteering with a health organization, where they put both their veterinary and human health training to work.continue
