But, these systems use broadly reactive primers that amplify RNA from either human rhinoviruses (HRVs) or enteroviruses, and results are reported as "entero-rhinovirus" or "human rhinovirus/

Recently, a pediatric hospital in Kansas City,Missouri has experienced over 300 cases of respiratory illnesses in their facility. Approximately 15% of those illnesses have resulted in children being placed in an intensive care unit.

hospital in Quincy, Illinois has barred children under 12 from visiting the facility until further notice due to an outbreak of an unknown respiratory virus that has affected more than 70 young children in the area, hospital officials said on Friday. More than 70 children complaining of respiratory virus symptoms visited the Blessing Hospital in Quincy, during the Labor Day weekend, they said.

The virus, has yet to be identified, but resembles HEV68, a respiratory infection that broke out in nearby St. Louis and Kansas City a week earlier,

The five children experienced paralysis of one or more arms or legs that came on suddenly and reached the height of its severity within two days of onset.

The children were treated but their symptoms did not improve and they still had poor limb function after six months. Two children tested positive for enterovirus-68, a rare virus previously associated with polio-like symptoms. No cause was identified in the remaining three children.

The MBCS in HA can be cleaved by ubiquitously expressed host proteases; this cleavage facilitates systemic virus replication and results in mortality of up to 100% in poultry (9, 10).

Although limited A/H5N1 virus transmission between persons in close contact has been reported, sustained human-to-human transmission of HPAI A/H5N1 virus has not been detected (13–15).

The viruses that caused the major pandemics of the past century emerged upon reassortment (that is, genetic mixing) of animal and human influenza viruses (22).

"The number of cases is rising exponentially," said Ban. "The disease is spreading far faster than the response. People are increasingly frustrated that it is not being controlled." "[W]e agreed to establish an Ebola crisis centre to bring synergy and efficiency to the efforts of these many partners within and beyond the United Nations, " he said.

The NA protein of influenza A virus is not only required for virion release and spread but also plays a critical role in virion infectivity and HA-mediated membrane fusion.

When the virus particle encounters a cell, it binds the sialic acid-containing receptor and is rapidly taken into the cell before the NA protein can cleave the carbohydrate from the cell surface.
