Respiratory Illnesses Surge Across US: Flu, RSV, and COVID-19 Cases Rise

A concerning trifecta of respiratory illnesses – influenza, respiratory syncytial virus (RSV), and COVID-19 – is gaining momentum across the united States, prompting renewed calls for vaccination and vigilance.While influenza A remains stable, a rise in influenza B cases, coupled with increasing COVID-19 activity in eleven states and RSV in twenty-one, paints a complex picture of the current public health landscape.

Flu Cases Trend Upward, Pediatric Deaths Mount

After a three-week period of decline, influenza levels are once again elevated nationwide, according to the Centers for Disease Control and Prevention (CDC). The situation is particularly alarming for children, with the number of pediatric flu deaths reaching fifty-two this season. This figure suggests the current season may surpass last year’s record-breaking high. A staggering ninety percent of these young fatalities occurred among children who had not received the annual flu vaccine, underscoring its critical importance. “It is not too late to get vaccinated,” the CDC emphasizes.

Overall levels of acute respiratory illness are currently low to moderate in most areas, with Alabama and Arkansas reporting high levels. Flu cases are trending upward in thirteen states, while RSV cases are increasing in twenty-one.

did you know? – The flu vaccine is updated annually to protect against the strains most likely to circulate each season. Protection from the vaccine declines over time, so yearly vaccination is recommended.

COVID-19 and RSV Continue to Circulate

Alongside the resurgence of influenza, COVID-19 cases remain largely unchanged nationally, but are growing or likely growing in eleven states. RSV, a common respiratory virus that can be particularly hazardous for infants and older adults, is also experiencing increased activity in a notable portion of the country.

Pro tip – Frequent handwashing with soap and water, covering coughs and sneezes, and staying home when sick are effective ways to limit the spread of respiratory viruses.

Vaccine Progress Setbacks and Pharmaceutical Shifts

The fight against respiratory illnesses isn’t limited to current outbreaks. Developments in vaccine technology are also making headlines. French pharmaceutical company Sanofi announced on January 30th that it has discontinued development of its next-generation seasonal flu vaccine based on mRNA technology, despite continuing to pursue a pandemic flu vaccine. A company spokesperson stated that Sanofi has “deprioritized its mRNA-based seasonal flu vaccine program and does not anticipate launching an mRNA-based seasonal flu product in the near term.”

Simultaneously occurring, AstraZeneca, the UK’s largest drugmaker, will begin trading on the New York Stock Exchange on Monday, February 5th, following a listing upgrade. This move reflects the company’s increasing focus on the US market, where it generates nearly half of its revenue.

Meningococcal Disease Outbreak in Chicago

Beyond the widespread respiratory viruses, another public health concern has emerged in Chicago. The chicago Department of Public Health reports two deaths and at least seven cases of meningococcal disease in adults over the past two weeks – a higher-than-usual incidence for such a short period. This outbreak highlights the importance of awareness and prompt medical attention

Why is this happening? A combination of factors is driving the surge in respiratory illnesses. Lower immunity levels due to reduced exposure during the COVID-19 pandemic, coupled with the natural evolution of viruses, are contributing to increased transmission.The timing of the surge, coinciding with colder weather and increased indoor gatherings, also plays a role.
