Symptoms of Swine Influenza

Common Symptoms of Swine Influenza Virus

During the mid 20th century, a new strain of H1N1 influenza virus, which contains parts of swine, avian and human influenza was first identified in humans in Mexico. These human infections became pandemic around the world causing public health emergency of international concern. As the swine influenza virus is derived from animals, humans have very little or no immunity to prevent or control this disease. Transmission of influenza virus from pigs to humans occurs very rarely and does not always lead to human flu unless the individual has direct contact with pigs or someone with swine influenza symptoms.

Swine Influenza Symptoms

  • Influenza A H1N1 virus is just like another type of flu virus, with symptoms similar to the typical seasonal pandemic. The main difference between these two is that the swine influenza virus is new which most of us don’t have any resistance to it. Like normal seasonal flu, the swine influenza symptoms may include fever, sore throat, runny or stuffy nose, shortness of breath, fatigue and headache etc.
  • Depending upon the severity, the swine influenza symptoms may also include severe pneumonia and respiratory failure. However, in some cases it is also associated with vomiting and diarrhea. These signs may generally vary from person to person based on age and previous health condition.
  • Persons with swine influenza symptoms having serious infection are considered as potentially communicable for up to 7 days from the onset of the illness. Normally these signs appear between two to four days after getting exposed to this contagious virus.

For More Complicated Cases In Swine Influenza

  • Children under the age of two, pregnant women and persons with chronic medical problems are considered as high risk groups with more vulnerability to the complicated illnesses and life threatening infections. If swine influenza symptoms are more predominantly seen in these groups then it is advised to seek medical attention immediately.
  • It is very important to recognize the swine influenza symptoms at an early stage before it turns into a serious illness. Patients with confirmed suspicion for influenza infection are required to take antiviral treatment along with additional supportive measures to reduce these symptoms severity and decrease the high risk of complications.
