Influenza - United States, 1989-1990
Article Abstract:
The Centers for Disease Control reported a decline in influenza cases between October 1, 1989 and April 30, 1990. The first influenza virus that was isolated in the United States during this period was reported in Wisconsin in September 1989. The next viruses were isolated in the week of November 18, 1989 in four other parts of the country. The largest number of specimens was submitted for analysis in January and February 1990; an average of 2,021 specimens were examined per week. By the end of February 1990, the World Health Organization reported the isolation of 2,785 influenza viruses. The type which predominated in the winter was influenza A, with influenza B being more prevalent in March and April of 1990. An average of 3 percent of patient visits to physicians were considered influenza-related in October and November 1989; this rose to a seasonal high of 8.9 percent in the last week of December. The importance of continued monitoring and culturing of influenza viruses is stressed in order to improve prevention and treatment strategies.

Update: influenza activity - worldwide, 1996
Article Abstract:
Between Oct 1995 and Aug 1996, epidemics of influenza occurred throughout the world. Influenza A(H3N2) virus caused most of the illness in most European countries, China and some parts of the US, while influenza A(H1N1) virus was responsible for influenza in Japan, Canada, most of the US and some European countries. Influenza B virus was associated with sporadic outbreaks in Europe. The 1996-1997 influenza vaccine has been updated to cover these viral strains. Elderly people in nursing homes should be vaccinated as well as health care workers who care for them. Amantadine and rimantadine are also effective against influenza A.
