Flu Swine Symptoms

The swine flu is caused by the H1N1 influenza type A virus. Viral infections resulting in seasonal flu usually subside after a week or so. However, the swine flu is a newly recognized strain of influenza that has the potential to cause serious health complications, including death. Rapid transmission and global mobility has allowed the virus to infect a large number of people at the same time.

With a virulent virus like the swine flu, a pandemic crisis can develop that may be difficult to control. In this article you will learn about swine flu symptoms and how they differ from normal seasonal flu symptoms.

Symptoms of Seasonal and Swine Flu

Influenza type A and B are responsible for the seasonal flu. Influenza type B has mild to moderate symptoms and is not associated with pandemic flu. Influenza type A is responsible for moderate to severe symptoms, and may lead to further health complications. The swine flu is an influenza type A virus.

Symptoms of seasonal flu and swine flu include:

  • Body aches
  • Chills
  • Coughing
  • Dizziness
  • Fatigue
  • Fevers (up to 106 degrees Fahrenheit)
  • Flushed face
  • Headache
  • Nausea
  • Sneezing
  • Sniffling
  • Vomiting.

One does not have to express all of the listed symptoms to qualify for an influenza infection. Fevers, chills, fatigue, sneezing, and coughing are usually the most common symptoms reported.

Symptoms Specific to Swine Flu

Because the swine flu is an influenza type A virus, the symptoms include all of the ones listed above for the seasonal flu. It is actually very difficult to determine if one has the seasonal flu or the swine flu simply based upon symptoms.

Data collected from health professionals suggest that swine flu symptoms usually include diarrhea and vomiting. Fatigue is also reported in nearly every case. Though it is very rare, as with the seasonal flu, neurological symptoms may occur and include seizure-like activity or mental status changes.

Doctors will not know for sure if you have the swine flu unless a swab sample is sent for laboratory testing. The testing has to be done early in the infectious phase while the viral particles are still shedding. Testing is usually reserved for those in high-risk groups, such as immunocompromised patients, so that proper treatment can be executed. Usually, the diagnosis of swine flu infection is made clinically by asking questions about proximity to confirmed outbreak locations, sick contacts, and other pertinent social history.
