A Triple Threat: Flu, RSV, and COVID-19 Impacting Health Systems
Written on
Chapter 1: Understanding the Current Health Crisis
A significant increase in flu cases, described as the worst in a decade, is straining hospitals across the U.S., according to the CDC. This situation, termed a "tripledemic," involves not only the flu but also respiratory syncytial virus (RSV) and COVID-19.
The Centers for Disease Control and Prevention (CDC) estimates that there have been around 23,000 hospitalizations and approximately 1,300 fatalities due to the flu this season, alongside 2.8 million other illnesses. Alarmingly, both cases and hospitalizations have doubled within a single week. The peak flu season typically begins in mid-December, with the highest activity expected in January or February.
Have you received your flu vaccination yet? My husband and I got ours last month, along with our COVID booster. Although I haven't had the flu in several years, I'm relieved to have received the vaccine, which lowers our risk, though it doesn't eliminate it completely.
Section 1.1: What is a Tripledemic?
So, what exactly does "tripledemic" mean? It refers to the simultaneous surge of flu, RSV, and COVID-19 in the U.S. The flu and RSV are seeing early increases this season, while COVID-19 cases, which had declined during the summer, are expected to rise again as cooler weather approaches.
With the holiday season approaching, people will gather indoors more frequently, increasing the likelihood of COVID-19 transmission. Hospitals are already overwhelmed, particularly those treating children, with over 75% of pediatric beds occupied. This surge is primarily due to RSV, leading some hospitals to postpone pediatric surgeries. In regions like Arizona and Rhode Island, children’s hospital beds are fully occupied.
To complicate matters, there is a shortage of healthcare workers, which means that while there may be available beds, there aren't enough staff to care for the patients.
Dr. Roberto Posada, a pediatric professor at Mount Sinai Kravis Children’s Hospital in New York City, notes that the low incidence of RSV and flu in the past two years may have weakened the population's immunity, as people were less socially active and adhered to masking guidelines.
He emphasizes the concerning possibility of all three viruses peaking concurrently, which could overwhelm hospitals, filling every bed and stretching the available staff thin.
Subsection 1.1.1: Areas Most at Risk
Dr. Buchholz, a pediatrician and founding medical director of primary care at Columbia University, highlights that states with colder climates are at higher risk for severe impacts from RSV, COVID-19, and the flu. He explains that cold weather encourages people to stay indoors and keep windows shut, which facilitates virus transmission. In warmer areas, people are more inclined to spend time outside and ventilate their homes.
The CDC has identified 16 states with “very high” flu activity as of November 10. The states experiencing the most significant outbreaks include:
- Alabama
- District of Columbia
- Georgia
- Mississippi
- North Carolina
- South Carolina
- Tennessee
- Virginia
Dr. Timothy Brewer, a professor of medicine and epidemiology at UCLA, warns that areas with low vaccination rates against the flu and COVID-19 are likely to face greater challenges with these viruses. Many Mountain and Southern states have not achieved high vaccination coverage; in some cases, less than 60% of eligible individuals have received their initial vaccine series. Furthermore, fewer than 10% of individuals in most states have received the updated booster targeting the prevalent omicron variant.
Chapter 2: Protecting Yourself During a Tripledemic
The first video discusses the alarming rise in hospitalizations due to flu, RSV, and COVID-19, with the CDC issuing warnings for the public.
The second video features doctors expressing their concerns over the increasing flu rates in various regions of the U.S.
To safeguard yourself during this tripledemic, getting the latest COVID-19 booster and the flu shot is crucial. Dr. Brewer reassures that this year’s flu vaccine appears to be well-matched to the circulating strains. Thankfully, both RSV and influenza are well-understood; there are established preventive measures and treatments available. Getting vaccinated for both the flu and COVID-19 as soon as possible is essential to protect yourself against these viruses.
