Flu experts are urging vaccination, especially as holiday gatherings approach, which can increase the risk of virus transmission.

The CDC has identified several respiratory viruses, including COVID-19 and RSV, that can cause flu-like symptoms, complicating diagnosis and treatment.

In a controversial move, Louisiana's health department has shifted its stance on vaccinations, now advising individuals to consult their doctors about flu and COVID-19 vaccinations, raising concerns among public health advocates.

Last winter's flu season was classified as moderate, lasting 21 weeks and resulting in an estimated 28,000 flu-related deaths, including a record 205 pediatric deaths.

The U.S. flu season has officially started, with significant increases in flu cases reported across the country as of December 20, 2024.

The CDC has declared the flu season based on various indicators, including lab results and emergency department visit data, although no dominant flu strain has been identified yet.

Recent weeks have seen sharp rises in lab tests and emergency room visits related to flu-like illnesses, indicating a steady increase in cases.

Thirteen states are reporting high or very high levels of flu-like illness, with Tennessee experiencing a notable spike, particularly in the Nashville area where about 25% of patients at a local clinic exhibit flu symptoms.

Vaccination rates are concerningly low this year, with only 41% of adults and children vaccinated against the flu as of early December, down from 44% for children last year.

Louisiana has emerged as another early hot spot for flu cases, with health officials noting a marked increase in flu-related illnesses among patients seeking medical care.

A significant factor contributing to the high pediatric death toll during the last flu season was low vaccination rates, with 80% of eligible children who died being unvaccinated.

While COVID-19 hospitalizations are decreasing nationally, RSV activity remains low overall but is elevated in the South, complicating the flu situation.
