  • What Are the Different Types of Flu?There are three types of flu viruses: A, B, and C. Type A and B cause the annual influenza epidemics that have up to 20% of the population sniffling, aching, coughing, and running high fevers. Type C also causes flu; however, type C flu symptoms are much less severe.The flu is linked to between 3,000 and 49,000 deaths and 200,000 hospitalizations each year in the United States. The seasonal flu vaccine was created to try to avert these epidemics.
  • What Is Type A Flu Virus?Type A flu or influenza A viruses are capable of infecting animals, although it is more common for people to suffer the ailments associated with this type of flu. Wild birds commonly act as the hosts for this flu virus.Type A flu virus is constantly changing and is generally responsible for the large flu epidemics. The influenza A2 virus (and other variants of influenza) is spread by people who are already infected. The most common flu hot spots are those surfaces that an infected person has touched and rooms where he has been recently, especially areas where he has been sneezing.
  • What Is Type B Flu Virus?Unlike type A flu viruses, type B flu is found only in humans. Type B flu may cause a less severe reaction than type A flu virus, but occasionally, type B flu can still be extremely harmful. Influenza type B viruses are not classified by subtype and do not cause pandemics.

  • How Is Type C Flu Virus Different From the Others?Influenza C viruses are also found in people. They are, however, milder than either type A or B. People generally do not become very ill from the influenza type C viruses. Type C flu viruses do not cause epidemics.

      what to look for the influenza
  • The 1918 Influenza causes twenty to forty million deaths worldwide. More than one half of the casualties from World War I were from the flu.The Flu infected 25% of United States troops during the war killing more than one million men, according to War Department records. The Flu caused 500,000 deaths in the United States. In the States alone, 25 million people became ill. Twenty Four out of Thirty Six military camps in the United States experienced an influenza outbreak. Thirty of the Fifty largest cities suffered from an "excess mortality" from the influenza
  • This flu virus had a high attack and mortality rate among young adults ages twenty to fifty and created a "W" shaped mortality curve as the youngest and eldest portions of the populations were at the extremes and young adults were the bulk of those infected. One of the major concerns with this strain of the influenza virus was that it caused pneumonia. The body's defenses are severely weakened which makes bacteria easier to invade and cause secondary complications.

  • influenza pandemic of 1918–19, also called Spanish influenza pandemic or Spanish flu,  the most severe influenza outbreak of the 20th century and, in terms of total numbers of deaths, among the most devastating pandemics in human history.
  • Influenza is caused by a virus that is transmitted from person to person through airborne respiratory secretions. An outbreak can occur if a new strain of influenza virus emerges against which the population has no immunity. The influenza pandemic of 1918–19 resulted from such an occurrence and affected populations throughout the world. An influenza virus called influenza type A subtype H1N1 is now known to have been the cause of the extreme mortality of this pandemic, which resulted in an estimated 25 million deaths, though some researchers have projected that it caused as many as 40–50 million deaths.
  • The pandemic occurred in three waves. The first apparently originated during World War I in Camp Funsto

  • n, Kansas, U.S., in early March 1918. American troops that arrived in western Europe in April are thought to have brought the virus with them, and by July it had spread to Poland. The first wave of influenza was comparatively mild; however, during the summer a more lethal type of disease was recognized, and this form fully emerged in August 1918. Pneumonia often developed quickly, with death usually coming two days after the first indications of the flu. For example, at Camp Devens, Massachusetts, U.S., six days after the first case of influenza was reported, there were 6,674 cases. The third wave of the pandemic occurred in the following winter, and by the spring the virus had run its course. In the two later waves about half the deaths were among 20- to 40-year-olds, an unusual mortality age pattern for influenza.
  • Outbreaks of the flu occurred in nearly every inhabited part of the world, first in ports, then spreading from city to city along the main transportation routes. India is believed to have suffered at least 12,500,000 deaths during the pandemic, and the disease reached distant islands in the South Pacific, including New Zealand and Samoa. In the United States about 550,000 people died. Altogether an estimated 25,000,000 persons throughout the world perished, most during the brutal second and third waves. Other outbreaks of Spanish influenza occurred in the 1920s, but with declining virulence

  • Rapid Worldwide SpreadWhen a pandemic flu virus emerges, expect it to spread around the world.You should prepare for a pandemic flu as if the entire world population is susceptible.Countries may try to delay the pandemic flu’s arrival through border closings and travel restrictions, but they cannot stop it.Overloaded Health Care Systems
  • Most people have little or no immunity to a pandemic virus. Infection and illness rates soar. A substantial percentage of the world’s population will require some form of medical care.Nations are unlikely to have the staff, facilities, equipment, and hospital beds needed to cope with the number of people who get the pandemic flu.Death rates may be high. Four factors largely determine the death toll:The number of people who become infectedThe strength of the virusThe underlying characteristics and vulnerability of affected populationsThe effectiveness of preventive measures
