H1n1 Influenza Pandemics

Influenza, a common disease frequently referred to as the “flu”, is one of the most widespread illnesses in the world. The disease, caused by the influenza virus, has infected both humans and animals for several centuries and has made its presence on every continent. In the past year, more than three million people were infected with influenza in the United States (Influenza “Flu”). Around 55,000 of those three million died, which makes influenza the eighth leading cause of death in the United States

most risk are airborne.”(Senthilingam, 2015). Therefore, I believe Influenza will cause the next pandemic. Reason being, the flu has the ability to disseminate before a person’s symptoms become visible. Unlike Ebola and SARS, which are only contagious once symptoms emerge (Senthilingam, 2015). Influenza viruses are significant human respiratory pathogens that cause both seasonal, endemic infections and periodic, unpredictable pandemics (Taubenberger

Influenza, Avian Influenza, and the Impacts of Past and Looming Pandemics Avian influenza is a disease that has been wreaking havoc on human populations since the 16th century. With the recent outbreak in 1997 of a new H5N1 avian flu subtype, the world has begun preparing for a pandemic by looking upon its past affects. In the 20th Century, the world witnessed three pandemics in the years of 1918, 1957, and 1968. In 1918 no vaccine, antibiotic, or clear recognition of the disease was known. Killing

BACKGROUND OF DISEASE The Spanish influenza was known by a few names such as the “mother of all pandemics” or “La Grippe”. It lasted from 1918 to 1919 and caused a global disaster. It killed more people than the “great war” which is known today as World War I. The Spanish flu took the lives of about 40-50 million people total. The Spanish influenza was so severe that it killed more people in just one year than in the four years of the Black Death Bubonic Plague, which lasted from 1347

Abstract Influenza has been around for thousands of years. It’s a disease that is responsible for the greatest viral outbreak in modern history. The amount of death each year associates with influenza is still among the thousands in fully developed countries. Influenza is a difficult disease to battle due to its high rate of mutation combined with its ability to bounce around different species. There are three type of influenza that are of most concerned when it comes to human’s pathology: Type A

Introduction The avian influenza virus is a type A influenza virus which is normally found in birds. Wild birds are the natural hosts for all known influenza type A viruses. This includes waterfowl, gulls and shorebirds. Ironically wild birds do not normally show symptoms of the influenza virus however when avian influenza type A viruses are passed onto domesticated birds, they are extremely susceptible to highly pathogenic avian influenza (HPAI) with a mortality rate of 90% to 100%1. Avian H2

Influenza is one of the most important human respiratory infections and its seasonal recurrence is a major contributor to human morbidity and mortality. Seasonal influenza has an estimated annual attack rate of 10-20%, leading to 3-5 million cases of severe illness and 250,000 to 500,000 deaths each year [1]. Throughout history, influenza A has also been the greatest contributor of human pandemics. During the last century, four influenza A pandemics (1918, 1957, 1968 and 2009) caused over 50 million

Avian influenza is a severe, often fatal flu virus of birds, especially poultry, that is transmissible from them to humans. Avian influenza A viruses are continuously detected in wild birds. From time to time, outbreaks of the influenza in poultry have occurred all around the world, causing illness and death in humans in Asia, Africa, Europe, the Pacific, and the Near East. On rare occasions, some avian influenza A viruses have also caused illness in humans in North America. Outbreaks of Avian flu

Influenza viruses are unique. They have the ability to avoid host immunity, therefore causing annual reoccurring epidemics of disease, and sometimes, major worldwide pandemics. The recognition of the variability in antigenic characteristics of influenza strains led to the establishment of a global Influenza Surveillance Network by the World Health Organization. The network monitors changes in viruses that cause outbreaks of influenza throughout the year all around the world. This article aims to

Spanish Influenza, took hold on Americans all over the country. There were three waves of pandemic which struck in the summer of 1918, fall of 1918, and the spring of 1919. After each wave, the virus mutated in order to adapt to the medicines and vaccines developed at the time in turn causing more and more death along the way. Due to the mutating illness, there were over 675,000 deaths in America; there were 50 million deaths worldwide. There were more deaths in one year of influenza pandemic than all
