The premature babies were confirmed to have parainfluenza type 3 virus infection. It is a seasonal virus associated with respiratory symptoms such as a cough and fever. There have been no new cases since then, according to hospital officials. The neonatal intensive care unit, which has 44 babies, remains open to visitors and patient admissions and the 3 affected babies are in isolation and being monitored closely. All are recovering, said hospital spokesperson Lillian Badzioch.The virus is not a flu virus and not associated with the H1N1 swine flu virus that is spreading in the community, according to Dr Chris Mackie, Hamilton associate medical officer of health. Mackie said although parainfluenza type 3 virus doesn't carry the same risks as regular seasonal influenzas, it does pose a risk for preemies [babies born prematurely]. Most cases do not require treatment and the virus is commonly seen in infants during spring and summer months. It can mimic the symptoms of the flu, Mackie said.Badzioch said, "It is very common in children under 2." But, she added, because it is in an intensive care unit and because the babies are all preemies, the hospital declared the outbreak and erred on the side of caution to prevent further spread. "We're already dealing with a fragile population and we wanted to take all the precautions."The hospital confirmed the cases on Saturday [27 Jun 2009], declared the outbreak on Monday and informed parents of babies in the unit, but only notified the general public yesterday [Thu 2 Jul 2009]. "If this was a serious disease with any risk to the public, this (declaring an outbreak) would have happened right away," Mackie said. "We don't expect any further cases."[byline: Carmela Fragomeni]-- communicated by:HealthMap Alerts via ProMED-mail<promed@promedmail.org>[The 1st parainfluenza virus discovered was Sendai virus (parainfluenza virus type 1) in 1952 in Japan. In 1955 type 2 was isolated from children with acute laryngotracheobronchitis (croup). In 1985 type 3 was isolated from children with respiratory tract infection. In 1960 type 4 was isolated from children with mild respiratory tract infections. The human parainfluenza viruses are pathogens that primarily affect young children, in whom the pathogenic spectrum includes upper and lower respiratory tract infections. The human parainfluenza viruses are responsible for 30-40 per cent of all acute respiratory tract infections in infants and children. These conditions include common cold with fever, croup, bronchiolitis, and pneumonia. They are also a cause of community-acquired respiratory tract infections of variable severity in adults.Human parainfluenza virus type 3 is 2nd only to respiratory syncytial virus as a cause of pneumonia and bronchiolitis in infants and young children. Outbreaks of HPIV-3 infections occur yearly, mainly in spring and summer, and last longer than outbreaks of the other types of parainfluenza virus.Reinfection with human parainfluenza viruses can occur throughout life, with elderly and immunocompromised persons being at a greater risk of serious complications of infections.The location of the city of Hamilton in the south of the province of Ontario can be found in the map of Ontario at <http://atlas.nrcan.gc.ca/site/english/maps/reference/provincesterritories/ontario/map.jpg>. - Mod.CP]
