The recent swine flu outbreak in Mexico has caused much trepidation among the international community, especially because of the increasing number of fatalities.
It is important to recognize swine flu symptoms to prevent the spread of infection and illness.
Swine influenza is a respiratory infection caused by the influenza type A virus, endemic in domestic pigs.
In the past, this flu has infected people only rarely - those infected being ones who have had direct and close contact to infected pigs.
But the current swine influenza outbreak in Mexico is different, caused by a new strain of the swine influenza virus.
As per recent health reports, swine influenza is being transmitted with surprising speed in humans, spreading easily from person to person, causing serious illness among those infected.
It has been reported that the disease has been diagnosed in humans who haven't had any exposure to pigs.
Among pigs, swine flu symptoms include sudden onset of fever, depression, coughing, sneezing, breathing difficulties, redness or inflammation of the eye, going off feed, and discharge from the nose or eyes.
Like the influenza virus affecting humans, H1N1 flu viruses are constantly mutating.
Although the swine influenza viruses are not the same as human flu viruses, swine influenza symptoms resemble those produced by regular human seasonal influenza.
In humans, common swine flu symptoms are fever, chills, sore throat, muscle pain, severe headache, coughing, lethargy, lack of appetite, weakness, and general discomfort.
Some may even experience runny or stuffy nose, nausea, vomiting and diarrhea.
However in humans, self care measures and appropriate treatment in the early stages of infection can reduce the increased risk of these complications.
In order to confirm that the illness is the result of a swine flu virus, one must undergo laboratory testing.
Antiviral drugs such as Tamiflu and Relenza are considered effective for the treatment and/or prevention of infection by swine flu viruses.
