The 2019-2020 flu season is two consecutive bad flu seasons. Unfortunately, two key indicators suggest that this year maybe more. This year the flu season has started early than any season in the past few years.
Nationally, more than 3% of the patients reported through the US Outpatient (ILINet) Influenza-like Illness Surveillance Network (ILINet) are due to influenza-like illness (ILI). According to the CDC (Centers for Disease Control and Prevention), the percentage exceeded the national benchmark of 2.4% for the fourth consecutive week. Last year, the levels of influenza-like illness were more than usual, and it almost lasted for more than 21 weeks. However, this highly active season is five weeks ahead of last year’s first week above baseline and did not appear until 49 weeks. More than half of the states in the United States have reached their highest level in the past decade. Doctors working with AccuWeather at the University of Virginia said that the second unique feature of the 2019-2020 flu season is the unusually early and active appearance of influenza B.
Also, Influenza B continues to cause severe illness among the victims. However, hospitalizations and deaths are less frequent than influenza A. Dr. Lewis also quoted that this season, there are more of Influenza B patients are more, which is very much odd. This early epidemic of influenza B may soon peak in many states and begin to subside before the expected rise in influenza A. The flu season usually starts in October, peaks between December and February, and lasts until March, although activity may last until May. The CDC also says that every season, the flu can make millions of Americans feel sick, hundreds of thousands of people are hospitalized, and an estimated tens of thousands of people die.
Another strange thing about the 2019-2020 flu season is the role that the Australian flu season may play in the United States. Australia is also two months earlier than usual, beginning an unusually early and initially severe season. However, as the season continued, the initial horrible predictions leveled off.
