H10N3 Bird Flu
News: the first case of human infection of H10N3 Bird Flu was reported in Jiangsu province of China.
It is a rare strain of a virus that normally infects poultry i.e. Avian Influenza.
This strain has low pathogenesis i.e. its transmission rate is less.
It is the most common type of Avian influenza.
It is largely restricted to birds, and often fatal to them.
As per the WHO, the H5N1 was first discovered in humans in 1997 and has killed almost 60% of those infected. Despite the fact that it is not known to transmit easily among humans, the risk still remains.
There are various subtypes of Influenza A and as per U.S. Centers for Disease Control and Prevention says all these subtypes infects birds except H17N10 and H18N11, which have only been found in bats.
Only two influenza A virus subtypes (i.e., H1N1, and H3N2) are known to infect humans.
Symptoms of the avian influenza:
mild upper respiratory tract infection (fever and cough),
early sputum production leading to severe pneumonia, sepsis with shock, acute respiratory distress syndrome, and even death.
Conjunctivitis, gastrointestinal symptoms, encephalitis and encephalopathy.
