Tips To Prevent The Spread Of Swine Flu
Swine flu is a highly contagious disease caused by a virus. It is believed that this influenza virus is endemic in pigs. The symptoms of the disease are
similar to those of influenza with chill, fever, sore throat, headache, coughing and weakness being the common features. Swine flu is normally caused
by influenza A sub-types such as H1N1, H1N2, H1N3 and H2N3. Besides persisting in pigs, this has also been circulated in human beings and is
presently contributing to world wide influenza.
Further research has revealed that the current outbreak is the result of a new strain which has not been previously found in pigs. The outbreak of
swine flu in May 2009 is believed to have links with the pigs at a farm in Alberta, Canada that had links with swine pandemic in Mexico. The initial
reports identify the new strain as swine influenza but its origin is unknown. Several countries immediately took up precautionary measures to reduce
the chances of global pandemic of the disease.
People working with poultry and swine / hogs are actively exposed and are at increased risk as influenza virus is endemic in these animals.
Vaccinating the workers and keeping a close watch on new strain may be an active public health measure to block its spread. Other professionals at
risk are veterinarians and meat processing workers. However, the risk element is less for such professionals than the farm workers.
Pigs which are infected with this influenza strain show feverish condition, lethargy and have apparent breathing difficulty. Direct transmission of swine
flu virus from pigs to humans is possible, but only occasionally. The 2009 swine flu outbreak has shown acute febrile respiratory illness. The most
common cause of swine flu fatality is respiratory failure. Other causes related to the disease and subsequent mortality is pneumonia, high fever,
dehydration owing to excessive vomiting and electrolyte imbalance. Elderly people and children are more prone to swine flu deaths.
