The Rise of Norovirus, Influenza, Measles, and Avian Influenza: What Is Fueling the Surge and How to Stay Safe

Public health experts stress the importance of prevention with norovirus infections, which have more than doubled according to the CDC since last season, and influenza, bird influenza, and measles concerns are rising. Valerie Cadet, PhD, a virologist, immunologist, and vaccinologist at PCOM Georgia, shares valuable insights on what’s driving this surge and how individuals can protect themselves and their families.

Why Are Norovirus Cases Surging?

Norovirus, a highly contagious virus known for causing severe gastrointestinal distress, is spreading rapidly in schools, nursing homes, and other communal settings. Cadet, also the assistant dean of health equity integration for POC all campuses, attributes this rise to a “rebound effect” following the COVID-19 pandemic. Hygiene measures like handwashing, surface disinfection, and social distancing helped suppress the spread of norovirus during the pandemic. However, as these habits have relaxed, the virus has regained momentum. Additionally, norovirus does not provide long-lasting immunity, meaning reinfection is possible.

Understanding Bird Flu Risks

H5N1, a strain of avian influenza (bird flu), has historically been limited to birds but has now infected some humans and cattle. While there is no current human-to-human transmission, Dr. Cadet emphasizes vigilance. Those who work with poultry or livestock should take precautions, such as avoiding contact with sick animals and following public health guidelines. Monitoring birds for unusual behavior or illness can also help identify potential risks early.

Strengthening Immunity and Reducing Risk

Cadet encourages a proactive approach to health. Strategies include:

• Vaccination: Staying up to date on flu, COVID-19, measles, and other recommended vaccines.
• Hygiene: Frequent handwashing and disinfecting high-touch surfaces.
• Air Quality: Using air purifiers and improving indoor ventilation to reduce airborne pathogen spread.
• Nutrition and Supplements: A diet rich in Vitamin C, Vitamin D, and Zinc supports immune function.

Combating Misinformation

Misinformation about viruses and vaccines spreads as fast as the diseases themselves, Cadet said. Common myths include the belief that antibiotics treat viral infections or that vaccines cause illness. Cadet advises using trusted sources like the CDC, the World Health Organization, and health care providers for accurate information. Cadet said, “Read it for yourself rather than listen to social media.”

About the measles vaccination, “My children have been vaccinated, Cadet said. “It's something that when you look at the outcome of measles disease at one point before we had the vaccine, it would run through communities worldwide, and everybody got it. But what we fail to know or remember acknowledges people had severe disease and some people died.”

Practical Steps for Staying Safe

Cadet’s advice is simple for those overwhelmed: “Focus on what you can control.” Vaccinate when possible, practice good hygiene, and stay informed. By taking proactive steps, individuals can confidently navigate this season of heightened illness.
