Avian Flu
KUMAMOTO JAPAN: Two Japanese chicken farms had to put down 112,000 chickens because of a new outbreak of bird flu. While there hasn’t been any transmission between birds and humans in Japan ever, the Avian Influenza Type A virus is still being handled with significant care to avoid any possibility of human harm. A Japanese Food Safety Commission publishing noted that avian flu was quickly broken down by stomach acid so there wouldn’t be foreseeable harm to any people if they ingested some of the contaminated chicken or their eggs. As a further precaution, authorities are banning the transportation of chickens and eggs within the affected areas. Additionally, vehicles are being inspected and disinfected near the chicken farms. These restrictions are posing financial problems for the farm owners who rely on steady sales to keep operating—the trade embargo and loss of a significant amount of livestock can be troublesome.
Avian Influenza has been documented in over 100 different types of birds. However, it is important to distinguish between the LPAI (low pathogenic avian influenza) and HPAI (high pathogenic avian influenza) variants of bird flu. LPAI can have side effects as negligible as rumpled feathers or a decreases in egg production. Sometimes it isn’t even detected by livestock keepers. While LPAI doesn’t seem very bad, the potential for real harm happens when LPAI Bird Flu virus mutates into the highly lethal HPAI type. The virus can mutate very quickly since it is a single-stranded RNA virus, characterized by often and extreme mutations. Birds infected with the high pathogenic avian influenza suffer a 90%-100% mortality rate in less than two days! The birds die from rapid degradation of many internal organs. Int...

Reducing the risk of salmonellosis from these farms would include food safety practices such as: washing eggs and hands thoroughly, making sure that the farm is kept in good condition, feeding the chickens good food, and using fresh water
I am a dedicated, focused student looking to push the boundaries of Engineering Physics with creative out of the box thinking. I have the drive to be successful and positively represent UBC Engineering Physics. I have a passion for physics and math which is why I believe this program is so appealing and a perfect choice. Having already started, run and sold a successful landscaping company, I have experience in entrepreneurship and have determined being an entrepreneur is something I want to pursue in the future. I believe Engineering Physics would give me the opportunity and breadth of knowledge to make my entrepreneurial vision a reality and allow me to find solutions to the issues that will impact the future of humanity.

However due to globalization, import and export viruses is more easily transmitted. Over the past century the global community especially Asian has been affected with new strains of the influenza virus. The changes in the virus can occur in two ways “antigenic drift” which are gradual changes in the virus over time. This change produces new strains that the antibody may not recognize. “Antigenic shift” On the other is a sudden change in the influenza virus which ‘’ results in a new influenza A subtype or a virus with a hemagglutinin or a hemagglutinin and neuraminidase combination that has emerged from an animal population,” as seen with H5N1 virus. This change leaves people defenseless against this new virus. (CDC, 2013) Currently there is no vaccine to combat all strains therefore “Planning and preparedness for implementing mitigation strategies during a pandemic requires participation by all levels o...
On January 4, 2011 President Obama signed into law The Food Safety Modernization Act (FSMA). This law has shed new light on the safety and security of our food supply. The last update to the food safety laws in the United States was in 1938. The food safety modernization act pays special attention at trying to modernize the food safety policies in the United States in hopes to prevent problems and concerns before they happen. As we all know, most of our food comes from overseas or sometimes from your neighboring state. The food products travel by car, truck, airplane, boat, or even train. We are all very happy to be receiving our bananas from Costa Rica and all of our other fresh fruits and vegetables that are imported into the United States, but we never stop to think about what pathogens are contaminating our produce and other foods on the way over and if they are safe for us to eat. In an article by Neal Fortin, he states that the law also gives the FDA new standards to hold imported foods to the domestic food standards and it also encourages the FDA to establish and develo...
Influenza is a major public health problem which outbreaks all over the world. Resulting in considerable sickness and death rates. Furthermore, it is a highly infectious airborne disease and is caused by the influenza virus. Influenza is transmitted easily from one person to another person which has a great impact on society. When a member of society becomes sick, it is more prone to spread to other people. In the United States, every year between 5 to 20 percent of the population is affected by influenza. As a result of this, between 3,000 and 49,000 deaths have occurred per year (Biggerstaff et al., 2014). Therefore, the influenza vaccine is the most effective strategy to prevent influenza. This essay will examine two significant reasons for influenza vaccination which are the loss of workforce and economic burden as well as one effect regarding herd immunity.

Food safety is an increasingly important public health issue. Governments all over the world are intensifying their efforts to improve food safety. Food borne illnesses are diseases, usually either infectious or toxic in nature, caused by agents that enter the body through the ingestion of food. “In industrialized countries, the percentage of people suffering from food borne diseases each year has been reported to be up to 30%. In the United States of America, for example, around 76 million cases of food borne diseases, resulting in 325,000 hospitalizations and 5,000 deaths, are estimated to occur each year.” (Geneva 2)

From a very young age, I have enjoyed reading a wide spectrum of topics. However, during high school, I had become preoccupied with physics during my studies and readings, and so I began to focus my attention upon the materials that further shed light on the science. The more I read, the more I became intrigued with the interrelations between matter, energy, and time and space motion illustrated through the science. Therefore, motivated to become one of Saudi Arabia’ few female physicists, upon graduating from high school I opted to major in the science that captivated me like no other....
The swine influenza or swine flu is a respiratory disease in pigs that is caused by the type A influenza viruses. These viruses are referred to as swine flu viruses but scientifically the main virus is called the swine triple reassortant (tr) H1N1 influenza virus. When the viruses infect humans they are called variant viruses. This infection has been caused in humans mainly by the H1N1v virus in the United States. The H1N1 virus originates in animals due to improper conditions and the food they ingest. The virus stays in latency form, thus harmless to the respective animal. The longer the animals survive the more likely the virus is to develop and strengthen making it immune to vaccines. The virus reproduced through the lytic cycle. The virus injects its own nucleic acids into a host cell and then they form a circle in the center of the cell. Rather than copying its own nucleic acids, the cell will copy the viral acids. The copies of viral acids then organize themselves as viruses inside of the cell. The membrane will eventually split leaving the viruses free to infect other cells.

In 1918-19 approximately 50 million deaths were a detriment of the Spanish H1N1 virus pandemic; a respiratory virus. According to the World Health Organization, the second Influenza A H1N1 pandemic in 2009 spread to more than 200 countries causing more than 18 000 deaths. Before the World Health Organization had announced the official end of the pandemic in August 2010, in July 2009 the World Health Organization sent out a phase 6 warning that H1N1 could soon be a global pandemic. It is important to recognize that the 2 different outbreaks had different A/H1N1strains effecting the world population; this suggests A/H1N1has a high ability for mutation, severely complicating the human body’s natural immune mechanism of antigenic drift.
