Respiratory illnesses and stomach flu circulating in Chippewa Valley
EAU CLAIRE—Various respiratory illnesses as well as the Norovirus, otherwise known as the stomach flu, are circulating in the Chippewa Valley.
'We've seen an increase in COVID-19, RSV, influenza, as well as Norovirus in the area,' said Rachel Mukai, communicable disease specialist for the Eau Claire City-County Health Department. 'In particular, influenza has been increasing at a pretty significant rate. Hospitalizations related to the flu have increased significantly in recent weeks, impacting individuals of all ages.'
Mukai said that starting in October of 2024, there have been around 116 hospitalizations due to influenza. In comparison, there have been 77 hospitalizations related to COVID during that time, and 30 related to RSV.
'If you do end up feeling sick, it's really important to stay home until you are well,' she said. 'If it's a respiratory, we recommend staying home for 24 hours after your fever has resolved and you are no longer taking fever reducing medications before you return back to work or school.'
Mukai said that with Norovirus, the window for waiting to return to work or school is slightly longer, though the duration of the illness is generally shorter.
'That one would be a 24 to 72 hour illness,' she said. 'It tends to include things like diarrhea and vomiting and abdominal cramping. It's a really good practice to stay home until 48 hours after your symptoms have resolved.'
Influenza, COVID, and RSV have similar symptoms.
'They can come with fevers, coughs, shortness of breath, fatigue — things like that,' she said. 'One of the big distinguishers for influenza is that the symptoms come on very suddenly. And just as a note, influenza doesn't stereotypically include vomiting and diarrhea. That tends to more fall into the stomach flu category or Norovirus.'
Mukai said that those with respiratory illnesses are free to take an at-home COVID test, but that COVID activity is primarily tracked through wastewater data.
'We're currently at a high level right now in Eau Claire,' she said. '[The wastewater data] is one of the best indicators we have at this point because COVID-19, as a disease itself, is no longer reportable. Hospitals do still report but that tends to be a lagging indicator.'
For those not sick, she recommended washing hands for a full 20 seconds with soap and water and ensuring if you're going to get together with family or friends, to ensure no one is sick.
'Even though we're kind of late in the season, with the high levels of respiratory illness, it's still really important to get vaccinated. You can still get the flu and COVID vaccines. Talk to your local pharmacy or your provider. There is also a vaccine for RSV, but that is for a limited population who can receive those vaccines. It's recommended for most infants and anyone over the age of 75.'
Mukai said other individuals who might qualify for the RSV vaccine would need to contact their provider to inquire about it.
The rise and respiratory illnesses and Norovirus has been going on for at least the last two weeks.
'When we are going to hit the peak yet in our county I'm hoping is soon, but we don't have any indication that we've peaked at this point,' she said.

How long does a cold last? And how long are you contagious?
Many people think of December and January as the two months of the year you're likely to catch the common cold, but 'cold season' actually stretches from late August through April. That means only about three months of the year, typically May through July, fall outside it. But even during these 'off' months, nearly one in 10 people still catch a cold, according to data from the U.S. Centers for Disease Control and Prevention. In other words, in any given month, tens of millions of people are walking around with telltale cold symptoms like a stuffy nose, headache, fatigue, sneezing, sore throat and sometimes a cough or low-grade fever. Here's what causes colds to spread so easily, how long they are usually contagious and how they're most commonly treated. What are the main causes of a cold? The common cold is most often caused by a viral infection. Rhinoviruses are the leading culprit, but other viruses such as adenoviruses, certain coronaviruses, respiratory syncytial virus (RSV) and parainfluenza viruses can also trigger cold symptoms by infecting the upper respiratory tract. Need a break? Play the USA TODAY Daily Crossword Puzzle. These and more than 200 other viruses spread through saliva or mucus particles expelled from a sick person. 'To catch a cold, you must introduce a cold virus from someone else into your airway,' says Dr. David Hill, a North Carolina-based pediatrician and spokesperson for the American Academy of Pediatrics. This typically happens when infected respiratory droplets are released into the air when a sick person talks, sings, sneezes or coughs. In addition to being inhaled directly, viruses can also land on surfaces and spread when someone touches a contaminated surface and then brushes their nose, eyes or mouth. 'Being in shared spaces often increases the likelihood of transmission,' says Dr. Alison Mitzner, a New York City-based board-certified pediatrician and author of "Calm and Confident Parenting." Other risk factors include a weakened immune system, preexisting health conditions, exposure to cigarette smoke, colder months with lower humidity (which dry out nasal passages) and aging. "Sleep deprivation and fatigue can also make people more susceptible to catching a cold," adds Hill. How long are colds contagious? One of the reasons colds spread so frequently is that they are contagious even before symptoms begin, often one or two days beforehand. After that, "you're usually contagious for as long as you have symptoms, which typically last seven to ten days," says Mitzner. While germs can spread anytime throughout this period, the most viral shedding tends to happen around days four to six. "Know that you can remain contagious for up to two weeks though," she adds. Hill says it's also important to note that "different cold viruses have different levels of contagion." RSV, for example, "is extraordinarily easy to transmit at it can survive on surfaces for hours," he explains. Yes, pneumonia can be contagious. But here's why it depends on the form. How are colds treated? While symptoms can almost always be managed, 'there are no treatments that shorten the duration of a cold,' says Hill. Instead, "every cold just needs to run its course," says Mitzner. To relieve symptoms in the meantime, Hill recommends saltwater nasal rinses for congestion or using nasal decongestants like oxymetazoline if symptoms are especially bad. But he cautions against using them for more than two to three days due to the risk of rebound congestion which, he says, "may be worse than the cold itself." Medications such as acetaminophen or ibuprofen can also reduce fever and alleviate sore throat or headaches but should not be given to very young children without medical advice. For younger kids, Hill recommends honey as a natural cough and sore throat remedy, though he emphasizes that infants and kids under 1 year should never be given honey due to the risk of botulism. 'When you catch a cold, it's important to let your body heal,' says Mitzner. That means rest, hydration and the use of 'a cool-mist humidifier at night to breathe easier.'

Novavax Stock (NVAX) Gets a Boost from ‘Robust Immune Responses'
Novavax (NVAX) stock jumped on Wednesday after the vaccine maker released results from a Phase 3 clinical trial of its COVID-19-Influenza Combination (CIC) and stand-alone flu vaccine. The initial cohort results from this study included 'robust immune responses' for the CIC and flu vaccine that were comparable to licensed rivals Nuvaxovid and Fluzone HD. Confident Investing Starts Here: Additionally, Novavax noted that the two vaccines were well tolerated. Almost all of the adverse events, greater than 98%, that were experienced by patients were mild or moderate in severity. The trial includes roughly 2,000 patients aged 65 or older. Novavax stated that it will continue to seek partners to further the development of its CIC and stand-alone flu vaccines. The results from this study provide it with the data it needs for discussions with potential partners. NVAX Stock Movement Today While NVAX stock had soared more than 2% in pre-market trading, the company couldn't maintain those gains. As a result, the stock is only up 0.56% as of Wednesday morning. Investors will also note that shares are down 8.83% year-to-date and 54.6% over the past 12 months. The Phase 3 clinical trial data also failed to attract investor interest today. Trading volume was muted at 1.38 million shares, compared to a three-month daily average of roughly 11.29 million units. Is Novavax Stock a Buy, Sell, or Hold? Turning to Wall Street, the analysts' consensus rating for Novavax is Hold, based on one Buy, two Hold, and a single Sell rating over the past three months. With that comes an average NVAX stock price target of $11.25, representing a potential 55.39% upside for the shares. Spark, TipRanks' AI analyst, highlighted 'strong revenue growth and profitability improvements' but warned of 'negative equity and cash flow challenges.'

Editorial: Ax to the vax — RFK Jr. continues on his anti-vaccine warpath
It's time for President Donald Trump, despite his own casual relationship with the truth, to stop putting American lives at risk and get rid of his dangerous quack in chief, Health and Human Services Secretary Robert F. Kennedy Jr. In his latest broadside against science, Kennedy is removing all 17 members of the Advisory Committee for Immunization Practices, the CDC's main advisory body, to ostensibly restore 'public trust above any specific pro- or anti-vaccine agenda.' God protect us, as RFK won't. This is how a society becomes undone. Science and reason get stepped on by half-truths and conspiracy theories. Next comes preventable death and disease. The problem is that there is no anti-vaccine side in the legitimate practice of science and medicine. The department's accompanying press release denigrated 'public health ideology' as if the practice of public health wasn't the CDC's only function. Researchers and doctors should be biased in favor of evidence-based therapeutics that save lives. Railing against bias towards vaccines is like a politician condemning researchers biased in favor of seatbelts in cars or keeping lead out of household paint. It's idiotic. We understand that the Make America Healthy Again movement Kennedy leads is all about questioning medical and nutritional practice. On a really abstract level, we are in agreement that no scientific truisms should be entirely above questioning — such a perspective would be anti-science. But there is a specific and long-standing methodology for actually answering those questions, and it is not debate club or who can most incite crowds of followers. It is the scientific method, under which hypotheses can be rigorously tested in ways that are replicable and based on clear and clearly laid out evidence. In that arena — really the only arena that actually matters when it comes to public health — the safety and efficacy of vaccines has been conclusively established. There is no additional discussion necessary or appropriate, particularly when it comes to immunizations that have now been standard-issue for decades and have by all measures radically decreased illness and mortality where they've been successfully deployed. The measles vaccine will always be better for individuals and public health than getting the measles. The same is true for polio, tetanus, COVID and all else. Preying on public skepticism of the pharmaceutical and health industries to hawk alternative approaches that are often unregulated and don't work is damaging it enough. Yet a true believer like RFK is more dangerous, especially now that he stands at the pinnacle of our nation's public health bureaucracy, a position that allows him to substantively impose his own anti-science view on an unsuspecting public and take the choice away from the American people. If RFK's new picks for ACIP — which the secretary falsely promised Sen. Bill Cassidy he wouldn't touch during his confirmation process — step back from recommending various crucial vaccines, this could substantially prevent even those who want to make the informed decision to receive inoculations or have their children vaccinated from being able to do so. As much as Kennedy and his followers emphasize the need for people to be able to make individual choices about their health, they seem hell-bent on taking that choice away entirely, especially given that insurance is not required to cover vaccines that are not CDC-recommended. We wonder what RFK will have to say for himself as once-eradicated diseases begin cutting through the U.S. population again. Is there anything that will get him to veer off this disastrous course? If the answer is no, and we suspect it is, then he must be removed before he can further damage public health. _____
