I attended Friday evening’s speaker session by Nathan Wolfe and found Wolfe’s presentation very intriguing. As an epidemiologist and microbiologist, Wolfe investigates outbreaks in animals. In the beginning, he explained that we think we know almost everything about living organisms in this world, yet do not. A lot of the microbial world remains completely unknown. If we were to create an encyclopedia of all living organisms, than 27 books out of 30 would consist of microbial organisms. There exists tremendous diversity in the microbial world, and although some are deadly, most can be helpful for us and the environment. However, humans’ first approach to the microbial world has been studying the most deadly ones. I am currently taking an introductory microbiology course, and thus, Wolfe’s talk about the microbial world and his investigations regarding various disease causing agents sounded extremely relevant and interesting for me.
Most of the diseases and epidemics that arose among human population originated from viruses and microbes in wild life animals. Occasionally, microbial-caused disease crossovers to humans to become human exclusive. Once this occurs, then the disease spreads over to a larger population, causing an epidemic. By the time that we reach this point, then it is too late and there is little that we can do to prevent the disease/harm. Due to the development of air transportation, connectivity across the globe has greatly increased, and such connected world allows for faster and more dangerous spread of these diseases. This is why Wolfe sought out to find ways to detect the disease-causing agents before they cross over or break out among the human or animal population. His research group goes out in the fields to monitor and detect indications of viruses and microbes that might cause diseases. He particularly studies individuals such as hunters who have direct contact with wild animals. These people have the risk of getting viruses from animals and spreading them to larger populations. Wolfe’s team have discovered several retroviruses in human and animal populations. By discovering these diseases, Wolfe hopes to build a global safety net that protects humans and animals. Fundamental awareness of these viruses/microbes are important even if we don’t find ways to prevent them. For example, if we had known that HIV was transmitted through heterosexual contact, then the political framing of AIDS and the negative socializing of the gay population could have been prevented.
Overall, I really enjoyed listening to Wolfe’s presentation which opened new perspectives in the field of global health. He seems like a great scientist with brilliant accomplishments for global public health!
