On Thursday, it has been reported by a biomedical team that Bird Flu is spreading with a fast pace but then good news is that it is less deadly as expected. This result was based on few blood serum evidences that were taken into consideration from various past mild infections in Asia.

Basically, farm workers are more prone of catching bird flu. This flu does not travel from person to person; it in fact spreads from poultry to people.

Around 600 cases of bird flu were reviewed, and according to World Health Organization, around half of them were killed because of the disease. Well, this ratio in comparison to the results of this study released by journal science looks over estimated.

In this regard, as told by microbiologist Taia Wang of the Mount Sinai School of Medicine in New York who was the lead author of this study, "WHO does not account for a majority of infections, but rather the select few hospitalized cases that are more likely to be severe. That could mean an undercount of patients who suffer only minor bird flu illness, inflating the death rate.”

Since 1997 to 2009, 27 studies have been conducted in order to reveal the final and major impact of bird flu over people. For this, data of antibodies to the virus was collected from 12,677 Asians, Africans and Europeans. Among this group, around 1.2% people were suffering from mild bird flu infection. This ratio refers to millions of people who were infected by this flu all over the world. All of them were given treatment on time and their life was saved. Reviewing this report, the team stated that a whole lot of people do become infected from bird flu but then not everyone dies.
