Influenza type B, though generally less widespread than type A, poses a formidable threat for vulnerable populations like the elderly and the young.
A team of researchers from Scripps Research and Janssen Research & Development LLC has discovered an orally active small molecule that neutralizes influenza A group 1 viruses, the most common flu strains.
According to this week’s FluView report, overall influenza activity remains elevated and is similar to activity reported last week. 48 states and Puerto Rico continue to report widespread flu activity and 32 states are experiencing high influenza-like-illness (ILI) activity levels.
There's now another reason to get your yearly flu shot.
According to this week’s FluView report, seasonal influenza activity remains elevated and is similar to overall activity last week. Nationally, influenza-like illness (ILI) activity remains at 5.0%, and influenza activity is widespread in 49 states and Puerto Rico.
According to this week’s FluView report, seasonal influenza activity increased again this week, reaching a new high for this season.
The influenza vaccine may be less effective in the elderly because their B cells are less capable of producing antibodies that can adapt to protect against new viral strains, researchers report February 19 in the journal Cell Host & Microbe.
According to this week’s FluView report, seasonal influenza activity increased again this week, reaching a new season high.
There have been roughly three global pandemic influenza outbreaks each century for the past 400 years, each of which have resulted in larger numbers of infections and deaths. Secondary bacterial infections have been responsible for a significant proportion of deaths in previous pandemics.
When influenza viruses that infect birds and humans meet in the same cell, they can shuffle their genomes and produce new strains that might have pandemic potential. Think of this process, called reassortment, as viruses having sex.
