A New Threat: H7N9

The last week of classes is here, so naturally I'm studying for finals next week! The first final to study for is Epidemiology because I have that exam on Monday. Taking a break from studying, I decided to look into recent health news around the world and came across a story about Hong Kong confirming human cases of bird flu. The report was released today, December 3. For Hong Kong this is their first case of human bird flu. In February and April, China dealt with H7N9, but controlled the issue by shutdowns of chicken markets and farm quarantines. It has already taken the lives of 45 people in eastern China and a middle aged woman is in critical condition now. The woman may have become infected with the strain when she traveled to a bordering city called Shenzhen and bought and slaughtered a chicken. The virus is very lethal to humans, but birds show no symptoms at all. A few people have been in contact with the infected woman and are showing mild symptoms. Officials believe their are many more cases, but the lack of technology to diagnose the strain is a problem. The city's government has tightened their requirements, especially in hospitals, and is hoping to eliminate H7N9 soon. In order to control H7N9, the government may need to kill a number of birds, which is the global standard for controlling the avian flu that was established in 1997 after the H5N1 outbreak. Reading the article, I came across a segment about how diseases do not respect boundaries, I thought that was so interesting because as epidemiologists our work is not just isolated to an area, but may be spread out among many cities or even countries. It makes the job that much harder, but also that much more rewarding to trace how the disease traveled and figure out a plan of action for those affected. I’ll be following this story more as the government and health officials receive more information.
Stay tuned and happy studying to my fellow epidemiologists!

A Rare Re-emergence

In recent news, Princeton University has been making headlines, but not because of their brilliant students. Yesterday, ABC news reported the Ivy League university has been faced with the re-emergence of Meningitis B. Since March, seven cases have been diagnosed, a majority of these being students. There has been debate among the FDA, the nation and the school on whether to import the vaccine, Bexsero, into the United States, but after much deliberation, the FDA has approved the importation. The vaccine is approved in Europe and Australia, but not yet in the United States. Bexsero is the only vaccine used for the type B strain. Bacterial meningitis is pretty rare, but the B strain is seen frequently in the United States and Europe. One in ten die and one in five suffer permanent disability. New Jersey mandates those living in college dorms to receive the vaccine against the other strains of meningitis, but type B has a separate vaccination, which is why many are not aware. College campuses provide a perfect breeding ground for the bacteria and officials are urging students to not have close contact, drink from each other, share items, but to wash hands and cover their mouths. Symptoms can quickly develop and meningitis can be fatal! The major symptom attributed to meningitis is a stiff neck. Among the students interviewed, many seemed willing to consider the vaccine. From an epidemiologist standpoint, I would be interested in figuring out how the disease was transmitted among those infected individuals and why hasn't the U.S. approved this vaccine yet? I believe the United States needs to always be prepared for the re-emergence of once rare, or even eradicated diseases and have the necessary vaccines, prevention strategies and treatment to be as success as possible in all their efforts to eliminate the spread.

Water: Something We Shouldn't Take For Granted

On Monday, we had a guest speaker, Dr. Duran from Virginia Tech's faculty talk to our class about the water issues among developing countries around the world. He was such a knowledge person and very personable! I learned a lot from his lecture, but a very interesting finding he presented was how the women, in developing countries, were usually the gatherers of the water for the household. I found this unfair because women have so many other chores they must complete around the home daily and producing safe drinking water seems like the most daunting of the chores. In some developing countries, the government has installed pipes that run water into these areas, but when tested the water from the pipes usually contains fecal coliforms. We learned, the pipes do not circulate water continuously, creating pressure so this leads to cracking, which increases the chance of bacteria within the pipes.
Properly boiling and storing the water can prevent these fecal coliforms from appearing and reduce an individual's risk for illness, but many people in these developing areas run into obstacles. Dr. Duran was discussing how some people did not understand how to properly boil their water and were merely heating the water and then storing it in uncovered tubs. He also discussed how many people do not have the time or space to properly boil their drinking water and since those in their household seem free from disease, the "raw" water must be fine to consume without boiling. Listening to the guest speaker made me realize how I take such a basic necessity for granted. In our country, water is always available. We can make it hot or cold, run slow or fast, and have access to it everywhere! For those in developing countries, water can be deadly if it is not properly treated or an area is lacking it. I have found a new appreciation for my water and now I think twice about long showers and letting the water run continuously when brushing my teeth. Water shouldn't be something we take for granted, it should be something we always appreciate.

Let's Be The Cultural Cure!

The world is vast and full of unexplored outlets pertaining to health. Dr. Wallis and her Epidemiology class have begun to open my eyes to not only the issues existing in our own country, but those throughout the world. On Monday, we listened to a lecture on global health and it reinforced the notation that her class is providing insight into other parts of the world and the issues they are battling. On Monday, November 4, Nicaragua has been battling Dengue. This illness is a classic staple of the humid, South American climate and other parts of the world. Mosquitos are the main vector for the illness and thrive in moist, tropical climates. It has been an epidemic for some time and continues to cause illness throughout these populations. Currently, five children, ranging in age from 5 to 15, have Dengue fever and are in critical condition. Over 1,000 people have become hospitalized as a result of Dengue fever in Nicaragua. The government and Cuban health officials have acknowledged the current epidemic and are planning strategies to control the outbreak. Becoming educated about issues around the globe allows for a more diverse outlook on health prevention and treatment. It's so easy sometimes to enclose yourself in your own world and not explore areas outside of it. Dr. Wallis challenges me to take a step back out of this world and dive into one that I never paid attention too. By becoming educated and understanding other nations, you become more culturally competent and can then begin to think critically about prevention and implementation strategies that may be more successful than those strategies before. For example, the issue of unsuccessful relocation attempts of individuals living in urban slums, understanding their mindset, culture and way of life could lead to more successful strategies to overcome this problem not only in Europe, but throughout the world!

Around the World: Polio in Syria

In the United States, we have been fortunate enough to have a quite peaceful nation, free from many detrimental diseases. In Syria, the aren't as fortunate. Polio, an eradicated disease in many areas, like the United States, has resurfaced. The ongoing civil war is a major contributing factor in the resurfacing of the disease. Another factor is the prevalence of the disease among border countries, like Afghanistan. Officials believe twenty- two individuals have contracted Polio, a majority of these cases involve young children. To combat this suspected Polio outbreak, the World Health Organization is implementing a six month emergency vaccination program to hopefully prevent others from contracting Polio as well. Officials believe the only way to rid Syria of Polio is to "start over" with a new vaccination program. This new program would benefit all of the people of Syria, especially children. Children born after the beginning of the civil war have not had the opportunity to become vaccinated, thus leading to an increased likelihood of contracting Polio. Hopefully, the people of Syria can receive the vaccines and the prevention efforts will help to decrease Polio. THe ultimate goal is to eradicate the disease from the area, altogether.
In Epidemiology, I learned diseases don’t contain themselves within borders, they can spread amongst many countries and be detrimental to a vast majority of individuals. The study of Epidemiology can help to understand the spread of the disease throughout various populations, but also addresses ideas for prevention, like the implementation of the Polio vaccination program. They want to help prevent those who are not ill from becoming ill and limiting the amount of people that are sick. Throughout the class and writing these blogs I am learning so much about how Epidemiology can take many different shapes and help combat various issues all over the world.

The Gambia

On Monday, we were fortunate enough to have a guest speaker present via Skype. The guest speaker was Mr. Ed Sanyang from the University of The Gambia. He discussed with us the development of a study on traffic injuries within The Gambia. He was very passionate and had much knowledge about this developing study and I found it interesting how traffic injuries were such a big problem in the area. After class, I found a blog posting from last year addressing the number of crashes in The Gambia. The blog highlighted The Gambia has over 750 road traffic crashes a year and 95% can be prevented. The police reports suggest a major component is careless and irresponsible individuals. A point addressed by Mr. Sanyang that I thought was very surprising was the fact that alcohol and drinking under the influence is not a common problem associated with these traffic injuries, unlike crashes in the United States. The United States differs from The Gambia in this respect because in recent news many crashes in the U.S. involve distracted or drunk, irresponsible drivers. Mr. Sanyang agreed with the class that more road signs may help decrease traffic injuries, but with the geographical location of The Gambia many people travel through the area to get to other places, like Senegal. Having a guest speaker, like Mr. Sanyang increases my knowledge and awareness of other parts of the world. It is easy and common to enclose yourself in a bubble and never have the ability to gain knowledge outside of your own country. Listening to Mr. Sanyang speak about The Gambia makes me more aware of the problems and research going on in the area and also realize how diverse epidemiology can be.

Return of TB

Epidemiology is the glue of public health. It helps tremendously in uncovering the diseases within the populations all over the world. The study of epidemiology has helped the United States eradicate many, once fatal, diseases. Recent ABC news, from October 9, 2013, discusses a disease that has been at its lowest levels in the United States over the years has actually begun popping back up and claiming lives. Tuberculosis has been at record low findings among the United States populating for years, which is why doctors and other healthcare workers are having trouble recognizing the signs and symptoms. It is hard to understand a disease that has not been seen in our population for a long time. In Nevada, a mother of twins had a fatal encounter with the illness and so did her babies. After her death, an autopsy was performed, determining the cause was Tuberculosis. It is unclear whether the mother was tested for Tuberculosis, but only one of the twin babies was tested. In the hospital, screening took place among the workers there and 26 people tested positive for Tuberculosis. A major concern was the babies in the NICU. Special consideration must be taken with these babies because of their sensitive, underdeveloped immune systems. The attorney of the deceased woman is searching for answers and questioning the hospital staff in what tests where given and which ones were not. If the hospital failed to perform a Tuberculosis test then a lawsuit could happen. As we learned in class, mortality is always a tragedy, but the information gained from a death and the autopsy can hold valuable information for public health and epidemiology. Reading this article made me realize the realistic value of epidemiology and how the study of epidemiology applies to events like these in our own U.S. population.
