  • 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.

      Influenza of 1918
  • A viral infection of the respiratory passages known as influenza, or flu, may be accompanied by symptoms of fever, chills, headache, muscle ache, sore throat, and weakness. It is spread by breathing airborne droplets infected with one of three influenza viruses—A, B, or C. The incubation period is two to three days. In general, type A is more debilitating than type B, and type B more than type C. Since type C causes only minor illness, it is sometimes mistaken for a common cold. A person who has type C virus becomes immunized against type C for life. A person infected with a strain of type A or type B becomes immune to that strain but is still susceptible to infection with new strains of the virus. New forms of the type A virus arise throughout the world.
  • Since influenza is caused by a virus, the infection must run its course, usually lasting seven to ten days. Treatment includes bed rest, drinking fluids, and the use of pain relievers. Antibiotics may be used against secondary bacterial infection. The most effective preventive measure against influenza is vaccination. At the start of each year’s influenza season, vaccines of the various strains of type A and B viruses expected to be in circulation that season are available. The vaccine’s success rate is about 60 to 70 percent, and immunity is short-lived

      this is the transmission of the disease 
  • Yellow fever virus is an RNA virus that belongs to the genus Flavivirus. It is related to West Nile, St. Louis encephalitis, and Japanese encephalitis viruses. Yellow fever virus is transmitted to humans primarily through the bite of infected Aedes or Haemagogus species mosquitoes. Mosquitoes acquire the virus by feeding on infected primates (human or non-human) and then can transmit the virus to other primates (human or non-human). Humans infected with yellow fever virus are infectious to mosquitoes shortly before the onset of fever and for 3–5 days after onset.

  • Influenza is a viral infection that affects mainly the nose, throat, bronchi and, occasionally, lungs. Infection usually lasts for about a week, and is characterized by sudden onset of high fever, aching muscles, headache and severe malaise, non-productive cough, sore throat and rhinitis. The virus is transmitted easily from person to person via droplets and small particles produced when infected people cough or sneeze. Influenza tends to spread rapidly in seasonal epidemics. Most infected people recover within one to two weeks without requiring medical treatment. However, in the very young, the elderly, and those with other serious medical conditions, infection can lead to severe complications of the underlying condition, pneumonia and death.

  • There is no cure for yellow fever. Antibiotic drugs that can be used to treat other diseases do not stop yellow fever because they do not work against viruses. Treatment involves easing the patient’s symptoms with pain medication and fluids. Severe symptoms usually require treatment in a hospital.
