– CDC (@CDCgov) March 23, 2018  However, the authorities found that they received more reports of the B strain of influenza virus, which has slowly overtaken influenza A reports. In the week leading up to March 17, influenza B accounted for about 58 percent of the entire flu of the week
The virus strain, although different, can raise as many health problems as the A strain, according to the CDC.
"We know that diseases associated with influenza B can be as severe as diseases with influenza A," said CDC spokeswoman Kristen Nordlund to CNN. "We also know that influenza B tends to be more severe for younger children."
Officials said five children died of influenza during a week until March 11. Two of the deaths were associated with the influenza B virus. In total, 133 influenza-related child deaths were reported in this flu season.
Officials recommend that unvaccinated people receive the flu vaccine because influenza viruses continue to circulate. Last month, officials said the vaccine is "usually (works) better" against influenza B and H1N1 viruses than most against this H3N2 virus this flu season.
Norlund told CNN that the second wave of influenza cases was not unexpected.
"In the seasons when influenza A H3N2 was the predominant virus, we often see a wave of influenza B," she told the news channel. "Unfortunately we do not know what the Influenza B wave will look like."
