Avian influenza

A vaccine is a suspension of attenuated/weakened or killed microorganisms of a virus or bacteria administered for prevention, improvement of severity or treatment of infectious disease. The devastation of mankind by small pox many centuries ago lead to the origins of immunization. Smallpox is believed to have appeared around 10’000 BC. Mankind had long been trying to find a cure for this epidemic. The fatality of the disease caused deaths of hundreds of thousands of people annually while leaving…

abdominal muscles; a change skin hue to a sort of bluish-grey” (Douglas). This illness claimed approximately one million two hundred and fifty thousand people from 1831-1832 and 1847-1851. Another common disease in this era was influenza, or common day flu, common to today’s influenza the symptoms included fever, chills, muscle aches, cough, congestion, runny nose, headaches, dehydration and fatigue. This is an airborne disease unlike cholera…

“The Great Influenza” by John M. Barry is a narrative of the events that occurred during the Influenza pandemic of 1918. The author goes into depth about how the pandemic began as it slowly made its way around the world and how society reacted/changed from the disease. John Barry thoroughly explained the process of how the scientist answered the questions on Influenza. Such as the pathogen of the disease, the transmission, and ways to prevent it. As he explained the evolution of the disease, he…

Teaching is not only sharing knowledge and providing guidance for people to understand, it is also about learning. I’ve had prior teaching opportunities and have done a number of work-related, in-service education sessions in my place of employment, most considered informal. Presenting and teaching to an unfamiliar audience in the community, however, it’s a whole different experience. It’s an experience where I learned a great deal. This paper will discuss the overall teaching experience…

1 Mr I is suffering from seasonal influenza as he shows symptoms including sneezing, headache, muscle ache, malaise, dry, chesty cough, fever, fatigue and weakness because he can hardly sit up. These are all the symptoms of seasonal influenza (NICE, 2015). Although symptoms of colds and influenza are very similar, but his symptoms developed within two days which is relatively fast, proving that he suffers from influenza instead of cold. As symptoms of influenza develop a lot faster than cold.…

Public Health Problem Severe acute respiratory syndrome also known as SARS was caused by an unfamiliar animal coronavirus that highly took advantage of the “wet markets” in southern China to adapt and succeed as an infectious virus between humans. Hospitals and international travel were the main pathways that led to a local outbreak and eventually to a global scale. According to the World Health Organization (WHO) between November 2002 and July 2003, the outbreak of SARS caused 8,096 cases and…

Influenza Virus The flu is one of the most common diseases in the world. The cause of it is the influenza “flu” virus. The viruses’ structure plays a big part in how it spreads. It affects systems in the body and causes them to malfunction. When the systems malfunction, it causes flu-related symptoms. The flu is often confused with the common cold, but it’s much more deadly and, in some cases, can even be fatal. The influenza virus affects the respiratory, immune, and digestive systems. The…

The war has just begun. The war may be fought for maybe 2-14 days, cells against viruses making a splash but we never know who will win-- the cells or the virus. Ninety five percent of people exposed to rhinovirus say that they have never had it. Rhinovirus is a very deadly cold that makes 75 percent of those infected become ill. Rhinovirus harms the cells of the respiratory system making people have trouble breathing. A malfunction with rhinovirus is that it can cause many other infections. The…

The common cold is a common viral infection of the nose and throat. It has more than 3 million US cases per year. It spreads easily, is self-treatable, is self-diagnosable, lab tests and imaging are not required, and is short term, so it almost always goes away within days to weeks. Although more than 100 viruses can cause a common cold, there are two main ones. They are the Rhinovirus, which is most active in early fall, spring, and summer. It causes 10-40% of colds. The second one is the…

DNA viruses by inhibiting the enzyme inosine monophosphate dehydrogenase, which is needed for the synthesis of guanosine triphosphate. The final step in the process of events is lethal mutagenesis of the RNA genome. In vitro inhibition of RSV, influenza viruses and parainfluenza viruses is achieved at ribavirin concentrations of 3-10 mL. Ribavirin can be given by mouth intravenously or as an aerosol. In adults an oral dose of 600 mg slows peak plasma levels of 1.3 mL, and large dose of 1000 mg…
