Why This Year's Influenza Outbreak Demands Your Attention

Virginia finds itself in the dark red zone on the CDC's influenza activity map, signaling a "very high" level of flu cases sweeping across the Commonwealth. This alarming development prompts Janet Michael, host of The Valley Today, to reach out to Dr. Jeff Feit for an urgent conversation about protecting communities during this particularly aggressive flu season.

Dr. Feit, who serves as Valley Health's Chief Population and Community Health Officer and Chief Medical Information Officer, brings a unique perspective to the discussion. As a family physician who spent twelve years practicing in Page County before moving into healthcare leadership, he understands both the clinical realities of influenza and the broader public health implications facing Virginia's communities.

An Early and Aggressive Start

The numbers tell a concerning story. Currently, Virginia ranks in the second-highest category out of twelve gradients measuring influenza-like illness (ILI). In contrast, this time last year, the state sat three categories lower. Moreover, while last season's flu activity peaked in mid-February, this year's surge arrived much earlier, catching many residents off guard.

"We're overshooting," Dr. Feit explains, noting that the CDC tracks ILI rather than confirmed diagnoses because not everyone gets tested. This measurement captures people presenting with observable flu symptoms—body aches, fevers, headaches, nausea, and congestion—providing a more accurate picture of community spread than test results alone.

Furthermore, the tracking method resembles the wastewater monitoring used during the COVID-19 pandemic. Instead of counting individual cases, health officials measure the percentage of people walking through medical facilities who display flu-like symptoms, offering insight into how prevalent the virus has become in communities across Virginia.

Understanding the Viral Landscape

Influenza doesn't exist in isolation this winter. Instead, three major respiratory viruses circulate simultaneously: seasonal flu, COVID-19, and RSV (respiratory syncytial virus). While COVID-19 shows less seasonal predictability in its first five years, influenza remains decidedly seasonal, arriving in late fall and lasting through early spring.

RSV, once simply categorized as "just another cold" in adults, now receives more attention because healthcare providers can test for it easily. In young children, however, RSV causes serious illness and can lead to scarring that triggers asthma symptoms for years. Consequently, the medical community now tracks RSV alongside flu and COVID as part of the winter respiratory illness trio.

Dr. Feit emphasizes the importance of basic prevention strategies that became politicized during the pandemic but remain scientifically sound. "Before COVID, we used to say obvious things like, 'Hey, it's respiratory season. Wash your hands a lot,'" he notes. He recommends being conscious of shared surfaces—particularly those signature pens at pharmacies—and washing hands before touching your face, since that's how respiratory viruses typically enter the body.

The Flu Shot: Separating Fact from Fiction

Each year, scientists formulate a new trivalent flu vaccine targeting the three strains they predict will dominate six months ahead. Typically, two components target Influenza A (the more severe form) and one targets Influenza B. This year, concerns have emerged about whether the vaccine adequately matches the circulating H3N2 variant, though early studies from other countries suggest typical protection levels remain intact.

Nevertheless, Dr. Feit stresses that vaccine effectiveness exists on a spectrum rather than as an all-or-nothing proposition. "Very few things in the world are about all or none," he explains. "We live in a world of probabilities." While the flu shot prevents illness roughly 40-50% of the time, it proves even more effective at preventing hospitalizations and deaths—outcomes that matter most.

The CDC recommends flu vaccination for everyone over six months old. Additionally, people over 65 should receive a stronger formulation, though the regular vaccine still provides protection if the enhanced version isn't available. The vaccine remains widely accessible at pharmacies, doctor's offices, urgent care centers, and other convenient locations.

Debunking the "Flu Shot Gives You Flu" Myth

One persistent misconception continues to discourage vaccination: the belief that flu shots cause influenza. Dr. Feit tackles this myth head-on, explaining that most flu vaccines contain inactivated virus, making it impossible to contract influenza from the injection. Recipients may experience arm pain or occasionally feel unwell due to their immune system's response, but they cannot develop actual flu from the standard shot.

However, one exception exists. The nasal spray flu vaccine contains a live attenuated (weakened) virus, which can occasionally cause mild flu symptoms. For this reason, Dr. Feit recommends the injectable vaccine over the nasal spray.

Many people who claim they "got the flu from the flu shot" likely experienced one of two scenarios: either mild immune system activation that caused temporary discomfort, or they contracted a different respiratory virus around the same time. True influenza, Dr. Feit emphasizes, rarely gets confused with other illnesses once you've experienced it.

Recognizing Real Influenza

"The way you know somebody has the flu as a doctor is they walk in and they say, 'I feel like I got hit by a truck,'" Dr. Feit shares. This vivid description captures the severity that distinguishes influenza from common colds.

Classic influenza symptoms include severe body aches, high fever, chills, and intense headaches. Patients often report that even their hair hurts due to scalp sensitivity. Unlike a cold, which typically causes congestion and mild discomfort, influenza renders people truly miserable for about a week.

Importantly, influenza poses serious risks beyond discomfort. The 1918 Spanish flu pandemic, which killed millions, notably affected many young, healthy people. Scientists theorize this occurred either because strong immune responses proved deadly or because older individuals possessed partial immunity from a previous flu strain decades earlier. Regardless of the mechanism, the historical lesson remains clear: influenza can kill, and it doesn't discriminate by age.

The Critical 48-Hour Window

When flu symptoms strike, timing becomes crucial. Antiviral medications prove highly effective against influenza, but only if taken within the first 48 hours of symptom onset. Therefore, anyone who spikes a fever and experiences severe body aches should seek medical attention within 24 hours to receive these medications and recover faster.

Without antiviral treatment, patients typically suffer through a miserable week before gradually improving. However, approximately 5% of flu patients develop a dangerous complication: bacterial pneumonia. Dr. Feit describes this as a "double hump illness"—patients get sick, start recovering, feel better for a while, then suddenly spike another fever and develop a cough. This pattern signals bacterial pneumonia requiring different treatment.

Virtual Care and Modern Solutions

Valley Health continues developing virtual care options that balance convenience with diagnostic accuracy. Dr. Feit acknowledges the challenge: clinically distinguishing flu from COVID, RSV, or bacterial sinus infections without point-of-care testing proves difficult.

The organization works toward a hybrid model where virtual consultations can direct patients to drop-in testing locations. "The doctor on your phone might say, 'Hey, I think this is probably COVID. Why don't you stop in our clinic and get tested and then we can treat you,'" Dr. Feit explains.

During peak flu season, however, virtual diagnosis becomes more reliable. When influenza saturates the community and a patient presents with classic symptoms—102-degree fever, headache, severe body aches—the probability of influenza reaches approximately 95%, making treatment without testing more reasonable.

Beyond Conventional Medicine

While discussing prevention, Dr. Feit offers a measured endorsement of one herbal remedy: elderberry extract. Unlike vitamin C megadosing, which lacks solid evidence despite historical claims, elderberry extract has demonstrated effectiveness against influenza virus in test-tube studies conducted in Israel. The preparation, sold as Sambucol in the United States, represents the one herbal supplement Dr. Feit feels comfortable recommending for flu prevention, though he notes the evidence base remains limited.

Looking Ahead: Rural Health Transformation

Beyond immediate flu concerns, Dr. Feit shares exciting news about long-term community health improvements. Virginia recently received the first installment of a five-year Rural Health Transformation Grant, part of a $50 billion federal fund. The Commonwealth expects to receive nearly $1 billion over five years, money that will support rural healthcare infrastructure, provider training, and innovative technology solutions for transportation-challenged populations.

This funding represents a silver lining in challenging times, offering resources to address food insecurity, housing instability, and healthcare access in Virginia's most vulnerable communities.

Taking Action Now

As flu season intensifies across Virginia, Dr. Feit's message remains clear: get vaccinated if you haven't already, practice basic hygiene, and seek prompt medical attention if symptoms develop. The vaccine won't change to match any viral evolution this season, so waiting no longer makes sense.

For those around pregnant women, vaccination becomes even more critical, as pregnancy significantly increases flu severity. Similarly, families should consider that vaccination reduces household transmission—meaning perhaps only one or two family members get sick instead of everyone, allowing healthy members to care for ill ones.

Ultimately, this flu season serves as a reminder that respiratory viruses remain serious public health threats requiring both individual action and community-wide prevention efforts. By understanding the science, recognizing symptoms early, and accessing treatment promptly, Virginians can navigate this challenging season more safely.
