In Japan, about 20 million people were infected with pandemic (H1N1) 2009 virus between July 2009 and March 2010. About 60% of them were under 15 years, but only 38 pediatric deaths were reported. ⋯ The time from onset to appear dyspnea in patients with lower respiratory complications was very short, and encephalopathy also appears very rapidly. It is very important to observe clinical course closely and to start neuraminidase inhibitor within 48 hours.

Newborns should be considered to be at high risk of developing complications of novel influenza like pandemic influenza A (H1N1) 2009, because maternal antibodies are not transferred via crossing the placenta. In Japan, some newborns with pandemic influenza A (H1N1) 2009 appeared non-specific symptoms, such as fever, poor activity and sucking, and apnea. ⋯ Orally oseltamivir(3-4 mg/kg/dose twice a day for 5 days) was used for treatments of flu-infected newborns. Contact and droplet precautions were very important measures to prevent transmission of pandemic influenza A (H1N1) 2009 virus to newborns.

A new pandemic influenza A (H1N1) virus had emerged and rapidly spread throughout the world. The clinical pathological observations associated with severe cases of pandemic (H1N1) 2009 are similar to that of high pathogenic avian influenza (H5N1). In order to find the most effective treatment methods for this pandemic influenza (H1N1), we describe our experiences, investigations and collaboration studies of avian influenza (H5N1) in Vietnam in association of our cooperative study of pandemic (H1N1) 2009 in Mexico. Effective treatment methods for critical illness due to influenza will be discussed from medical, regional and global points of view, which may be applied for the treatment of any type of influenza virus.

Highly pathogenic avian influenza (HPA1) virus of H5N1 subtype has spread worldwide and continues to cause outbreaks in poultry and sporadic human infections since 2003. As of 9 April 2010, 493 confirmed human cases including 292 fatal cases were reported from 15 countries. ⋯ H7 subtype avian influenza viruses also pose a similar threat to humans as H5N1 subtype virus. We provide here an updated overview on the human infections of HPA1 viruses in the world.
