Influenza Vaccine Causes of the flu. The flu is caused by influenza virus types A, B, and C. Both type A and type B flu viruses are responsible for the seasonal outbreaks of flu. Type A flu viruses are found in many different animals, including ducks, chickens, pigs, and horses. Influenza B viruses circulate widely only among humans.nfluenza (also known as the flu) is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness, and at times can lead to death. The best way to prevent the flu is by getting a flu vaccination each year.

Types of Flu 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.

Hepatitis (Viral Hepatitis, A, B, C, D, E, G) 1 Viruses that primarily attack the liver are called hepatitis viruses. There are several types of hepatitis viruses including types A, B, C, D, E, and possibly G. Types A, B, and C are the most common. 2  All hepatitis viruses can cause acute hepatitis.  Viral hepatitis types B and C can cause chronic hepatitis.

The Agent There are three different types of influenza virus – A, B, and C. Type A viruses infect humans and several types of animals, including birds, pigs, and horses. Type B influenza is normally found only in humans, and type C is mostly found in humans, but has also been found in pigs and dogs.

- As determined by the CDC, the viruses in a flu shot and FluMist vaccine can change each year based on international surveillance and scientists' estimations about which types and strains of the flu will be most potent that year.irds are not cap able of carrying either type B or C influenza viruses. There are three main subtypes of avian flu, including H5, H7, and H9. The subtypes H5 and H7 are the most deadly, while the H9 subtype is less dangerous.

Types of Influenza Viruses Types of Influenza Viruses. Language: There are four types of influenza viruses: A, B, C and D. Human influenza A and B viruses cause seasonal epidemics of disease almost every winter in the United States. The emergence of a new and very different influenza A virus to infect people can cause an influenza pandemic.

Tension Headaches In this case, you might confuse your tension headache with a migraine, which is a type of headache that causes throbbing pain on one or both sides of the head. However, tension headaches do not cause all the symptoms of migraines, such as nausea and vomiting.

Hepatitis (Viral Hepatitis, A, B, C, D, E, G) The most common hepatitis viruses are types A, B, and C. Reference to the hepatitis viruses often occurs in an abbreviated form (for example, HAV, HBV, HCV represent hepatitis viruses A, B, and C, respectively.) The focus of this article is on these viruses that cause the majority of human viral hepatitis. All hepatitis viruses can cause acute hepatitis. 2  Viral hepatitis types B and C can cause chronic hepatitis. 3  Symptoms of acute viral hepatitis include fatigue, flu-like symptoms, dark urine, light-colored stools, fever, and jaundice; however, acute viral hepatitis may occur with minimal symptoms that go unrecognized.

Typhoid fever Hepatitis C type 1 virus is most common in the United States and Europe. Type 3 is most common in India, the Far East and Australia. And type 4 is most common in Africa and the Middle East. A global vaccine would have to protect against all these variants of the virus.

Viral Hemorrhagic Fever  (Crimean-Congo, Ebola, Lassa, Marburg, Rift Valley, Yellow Fever) All hemorrhagic fever viruses have single-stranded RNA genomes, which differ in polarity and in the number of segments (flaviviruses: positive-sense, 1 segment; filoviruses: negative-sense, 1 segment; arenaviruses: negative-sense, 2 segments; bunyaviruses: negative-sense, 3 segments).or example, many cases of Crimean-Congo hemorrhagic fever, Lassa or yellow fever are mild and go unrecognized, but Ebola and Marburg hemorrhagic fever is almost always a severe disease, in which the case fatality rate ranges from 50-90%.

Smallpox There are 2 clinical forms of smallpox: variola major and variola minor. Variola major is the severe and most common form of smallpox, characterized by a more extensive rash and higher fever. There are 4 types of variola major smallpox:

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.

Additional Tests You Might Need There are six major types of Hepatitis C around the world: genotypes 1, 2, 3, 4, 5 and 6. In the United States, genotypes 1, 2, and 3 are common: 1  Genotype 1: Most Americans (nearly 75%) with Hepatitis C have this type.  Genotype 2: About 10% of Americans with Hepatitis C have this type.

- Abstract. Bovine viral diarrhea virus 1 (BVDV-l) subtype b was isolated from premature Holstein calves from a dairy herd that experienced an outbreak of premature births, late-term abortions, brachygnathism, growth retardation, malformations of the brain and cranium, and rare extracranial skeletal malformations in calves born to first-calf heifers.

The emergence of a new and very different influenza virus to infect people can cause an influenza pandemic.nfluenza A viruses can be further broken down into different strains. Current subtypes of influenza A viruses found in people are influenza A (H1N1) and influenza A (H3N2) viruses. In the spring of 2009, a new influenza A (H1N1) virus (CDC 2009 H1N1 Flu website) emerged to cause illness in people.

- PATHOGENICITY/TOXICITY: Smallpox is an acute, contagious disease with two main forms, variola major and variola minor, both of which cause similar lesions(1). There are 4 types of variola major infection presentations.

Types of Flu Viruses Type A Flu Virus. The CDC distinguishes the subtype of influenza type A viruses by labeling it with an “H” and an “N,” depending on the type of proteins — hemagglutinin and neuraminidase — on its surface. Currently, there are two subtypes of A viruses that concern humans: The newer type is now simply known as H1N1.
