Signs & Symtoms of Swine Flu

In swine
Swine flu

In pigs influenza disease produce fever, lethargy, sneezing, coughing, difficulty breathing and decreased appetite. In some cases the disease can cause abortion. Although mortality is typically low (around 1-4%), the virus can make weight loss and poor growth, causing financial loss to farmers. Infected pigs can lose up to 12 pounds of body mass over a 3 to 4 week period.

In humans

Direct transmission of a swine flu virus from pigs to humans is irregularly possible (called zoonotic swine flu). In all, 50 cases are known to have occur from the first report in medical literature in 1958, which have resulted in a total of six death. Of these six people, one was pregnant, one had leukemia, one had Hodgkin disease and two were known to be before healthy. Despite these apparently low numbers of disease, the true rate of infection may be top, since most cases only cause a very mild sickness, and will probably never be reported or diagnosed.

swine symptoms in humans

According to the Centers for Disease Control and Prevention (CDC), in humans the signs of the 2009 "swine flu" H1N1 virus are similar to those of influenza and of influenza-like illness in general. warning signs include fever, cough, sore throat, body aches, headache, chills and fatigue. The 2009 outbreak has shown an greater than before percentage of patients reporting diarrhea and vomiting. The 2009 H1N1 virus is not zoonotic swine flu, as it is not transmitted from pigs to humans, but from person to person.

Because these symptoms are not exact to swine flu, a differential diagnosis of probable swine flu need not only symptoms but also a high likelihood of swine flu due to the person's recent history. For example, during the 2009 swine flu eruption in the United States, CDC advised physicians to "consider swine influenza disease in the disparity diagnosis of patients with acute febrile respiratory illness who have either been in contact with persons with definite swine flu, or who were in one of the five U.S. states that have reported swine flu cases or in Mexico during the 7 days preceding their sickness onset." A diagnosis of confirmed swine flu need laboratory testing of a respiratory sample (a simple nose and throat swab).

The most common cause of death is respiratory collapse, other causes of death are pneumonia (leading to sepsis), high fever (leading to neurological problems), dehydration (from excessive vomiting and diarrhea) and electrolyte imbalance. wounded are more likely in young children and the elderly.
