According to recent data, the United States is observing a notable decrease in COVID-19 and respiratory syncytial virus (RSV) activity across various states. However, influenza or flu activity remains high, indicating that the respiratory virus season is far from over.

Current Situation of Virus Activity
As per the data for the week ending January 27, COVID-19 admissions have fallen by nearly 11%. A similar trend is observed for RSV activity, which is also declining in many areas of the country. Despite this, flu activity remains high. As per the Centers for Disease Control and Prevention (CDC), 18 states are reporting high levels of virus activity. These include Alabama, Arkansas, Colorado, Kentucky, Louisiana, Massachusetts, New Jersey, North Carolina, North Dakota, Ohio, Oklahoma, Tennessee, Texas, Virginia, Wyoming, and the District of Columbia. The states of Georgia, New Mexico, and South Carolina are reporting ‘very high’ levels, classified as level 11.
Respiratory Virus Activity Levels
These virus activity levels reflect weekly visits to outpatient providers or emergency departments due to fever, cough, or sore throat. They are compared to periods of low circulation. The CDC’s respiratory virus activity level dashboard provides an update on the levels of various respiratory illnesses, including COVID-19, influenza, and RSV, at the national level.
Influenza Activity Increasing
While COVID-19 and RSV activity are decreasing, seasonal influenza activity remains elevated and is reportedly increasing in some parts of the country. Over 82,000 people have been diagnosed with influenza in the week ending January 27, as reported by CNN. The CDC estimates at least 20 million flu illnesses, 230,000 hospitalizations, and 14,000 deaths so far this season. Despite the high flu activity, the COVID-19 vaccine and this year’s flu shot offer strong protection, and it’s not too late to get vaccinated.
Decreasing RSV Activity
RSV activity has declined across many parts of the nation. Hospitalizations due to RSV are decreasing in young children but remain elevated in older adults. A study from Malaysia reports a significant inverse relationship between RSV and COVID-19 infections during the pandemic, with a sharp decline in RSV cases in 2020 and 2021. However, following the lifting of restrictions in 2022, RSV infections rose sharply. This highlights the need for the healthcare system to be prepared to address future RSV outbreaks.
Conclusion
The current trends in virus activity levels underscore the importance of preventative measures, such as vaccination, to control the spread of these respiratory viruses. While the decrease in COVID-19 and RSV activity is a positive sign, the continued high level of flu activity necessitates ongoing vigilance. It’s also important to remember that even with decreasing COVID-19 levels, it’s still crucial to get vaccinated and follow all necessary precautions to prevent the spread of the virus.
