Avian influenza, or chicken flu as it's more commonly recognized, was discovered over a century ago in Italy and to date, there are a number of strains of the bird flu virus. Many of these strains have grow to be deadly, notably the H5 and H7 strains. The deadliest one so far, the H5N1 strain, has reportedly killed 70 folks in Asia alone in the last years. Many scientists believe that if correct motion is just not taken, chicken flu has the potential to be the fourth major pandemic in the world.
Influenza has affected the lives of so many individuals, particularly in the 20th century. The Spanish Flu of 1918, Asian Flu of 1957 and Hong Kong Flu of 1968 killed not less than 20 million people worldwide.
Bird flu can spread rapidly since the chicken flu virus is typically discovered in the intestines of migrant birds that travel nice distances. Hen flu spreads when other birds, chickens or geese come in contact with an infected hen's saliva, nasal secretions or feces. Birds fall sick and die within forty eight hours of contracting the virus. People who work together with infected birds with out correct protecting gear are additionally at risk.
There are 4 reasons that scientists imagine that chook flu could turn into a pandemic.
1. Many nations, specifically third world international locations, do not have the proper amenities in place to deal with the hen flu problem. Without these services, there's a high possibility of the fowl flu virus spreading.
2. No vaccine has been totally developed and tested to fight fowl flu virus. Utilizing amantadine and rimantadine, two medicine that are used to treat influenza, on those contaminated with the virus has not been successful. Regardless that research is underway, there may be nonetheless no recognized remedy for chook flu in humans. Ought to a pandemic occur, it would take no less than 4 months to produce vaccines that may be distributed to individuals affected by the disease.
3. The avian influenza virus affects birds and pigs. Nonetheless, because the virus has completely different strains and so they simply mutate, scientists worry the virus could evolve into something worse and affect people directly. The virus may become airborne and be transmitted from one human to another.
4. People who work in farms and are in the poultry and livestock industry many not have the right equipment and adequate safety towards the disease.
A human who is possibly infected with chicken flu may show signs similar to human influenza. A person with chicken flu will expertise fever, sore throat and muscle pains. Because of the similarity of signs between bird flu and human flu, an individual with hen flu might be mistakenly diagnosed with human flu. Nevertheless, advanced symptoms of fowl flu include eye infections and mononuclear cell isolator
respiratory issues, which might turn into life threatening.
In 1997, when an outbreak of bird flu happenred in Hong Kong, 18 folks have been contaminated and 6 had been killed. As a fast response, Hong Kong's entire poultry inhabitants, which was estimated at 1.5 million, was killed. Many imagine that this rapid response to the bird flu outbreak was one of the best solution and helped avert it from changing into a pandemic.
Normally, there may be little risk of most people getting infected with chook flu because it requires shut or direct interplay with contaminated birds or fowl feces. Since the number of those that has been infected with the illness is still low and confined to a couple children and adults, there isn't a critical cause of alarm yet. Nevertheless, for those who have constant contact with birds, the risk turns into very high throughout outbreaks in native poultry
