Arrow Swine flue

Dear,

I think, it is important topic for 2010 EDS paper, So have a look over it for your knowledge.

Introduction

Swine influenza (also called swine flu, hog flu, pig flu and sometimes, the swine) is an infection by any one of several types of swine influenza virus. Swine influenza virus (SIV) is any strain of the influenza family of viruses that is endemic in pigs.

1918 pandemic in humans

The 1918 flu pandemic in humans was associated with H1N1 and influenza appearing in pigs;this may reflect a zoonosis either from swine to humans, or from humans to swine. Although it is not certain in which direction the virus was transferred, some evidence suggests that, in this case, pigs caught the disease from humans.

For instance, swine influenza was only noted as a new disease of pigs in 1918, after the first large outbreaks of influenza amongst people.Although a recent phylogenetic analysis of more recent strains of influenza in humans, birds, and swine suggests that the 1918 outbreak in humans followed a reassortment event within a mammal,the exact origin of the 1918 strain remains elusive.It is estimated that anywhere from 50 to 100 million people were killed worldwide.

Symptoms

According to the Centers for Disease Control and Prevention (CDC), in humans the symptoms of the 2009 "swine flu" H1N1 virus are similar to those of influenza and of influenza-like illness in general. Symptoms include fever, cough, sore throat, body aches, headache, chills and fatigue. The 2009 outbreak has shown an increased 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.

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

Treatment

n the U.S., on April 27, 2009, the FDA issued Emergency Use Authorizations to make available Relenza and Tamiflu antiviral drugs to treat the swine influenza virus in cases for which they are currently unapproved. The agency issued these EUAs to allow treatment of patients younger than the current approval allows and to allow the widespread distribution of the drugs, including by non-licensed volunteers.

Asalam-o-Alikum

O brother, Mashal Khan

I just posted to get possible good marks, Its not lengthy. Its very easy,
Just break it into points to remember the crust of the topic, Like:

1) Swine flue is influenza Virus, SIV Swine Influenza Virus
2) Its is not Zoonotic, because Zoonotic spread from Animal to Virus, But virus spread in 2009 is endemic and spread by Human to Human. ( Non-Zoonotic )
3) Causes: Cough, fever, cold, fatigue, body pain, pain swallow, aches, headache etc
4) Damage: Respiratory failure, High fever damages brain, pnuemonia, diarhorea etc
5) Treatment: Tamiflue, Its vaccine is prepared from Ostrich Egg.

Hope, it would be helpful.


Regards,
