(Family Features) Around the new year, many people set goals for better health. People ages 65 and older can kick off a healthy new year by getting vaccinated for flu, COVID-19 and RSV. These respiratory infections can become more dangerous as people age. Vaccines can help older people risk less severe illness and do more of what they enjoy.

Those who provide care for older adults can support their health by helping them get vaccinated now. That’s especially important because older people have a higher risk of getting very sick or even dying from flu, COVID-19 and RSV.

Vaccines help protect older adults from serious illness

As people get older, their ability to fight off infection decreases, putting them at higher risk for complications if they get a respiratory infection. They are more likely to get severely ill and need medical or hospital care from flu, COVID-19 and RSV. Those living in long-term care facilities often have health issues that make flu, COVID-19 and RSV serious risks.

The Centers for Disease Control and Prevention (CDC) urges all people ages 6 months and older to get this season’s flu and COVID-19 vaccines.

Those ages 75 and older – or ages 60 and older with certain health issues or who live in a nursing home – should get one dose of an RSV vaccine if they haven’t had it before. It’s safe to get vaccines for flu and COVID-19 (and RSV, for those who are eligible) all at the same time. Any side effects from the vaccines are usually mild and go away on their own in a few days.

Get vaccinated for a healthy new year

Vaccines are a great way for older people to start the year by protecting their health. Most deaths from flu, COVID-19 and RSV are in people ages 65 and older, and the risk grows with age. However, vaccines cut your risk of being in the hospital for flu or COVID-19 by about half and for RSV by about 70%, according to the CDC.

Those who look after older loved ones can help them avoid severe respiratory illness by helping them get vaccinated. In addition to getting vaccinated, there are other ways to help prevent serious illness. When around others indoors, use fans or open windows for better ventilation. Wearing a mask, using physical distancing and washing your hands often can also help. You can use home tests to check for COVID-19 if you have symptoms.

When a wildfire notification goes off on your mobile phone, it can trigger all kinds of emotions and confusion.

You might glance outside and see no smoke. Across the street, your neighbors have mixed reactions: One is leisurely walking their dog, another is calmly packing a small bag, while a third appears to be preparing for an extended vacation.

The notification advises you to grab your “go bag,” but then panic can set in as you realize you don’t have one ready. So, you scour the local emergency management website for guidance and discover how much you’ve overlooked: important documents such as birth certificates, an extra flashlight, your children’s medications, a phone charger.

Before you can gather your thoughts, a second notification arrives – this time telling you to evacuate.

Packing the car, wrangling children or a skittish cat, figuring out where to go – it can feel frenzied in the face of danger. As you pull out, you join a traffic jam on your street, with a black smoke plume rising nearby and neighbors still loading their cars.

This chaos highlights a worst-case scenario for wildfire evacuations – one that can cause delays, heighten risks for evacuees and complicate access for emergency responders. It’s why researchers like me who study natural hazards are developing ways to help communities recognize where residents may need the most help and avoid evacuation bottlenecks in the face of future disasters.

The importance of being prepared

Confusion is common in the face of disasters, and it underscores the need for communities and individuals to be prepared.

Delays in evacuating, or the inability to evacuate safely, can have catastrophic consequences, not only for those trying to flee but also for the first responders and emergency managers working to manage the crisis. These delays often stem from a lack of preparedness or uncertainty about when and how to act.

A study of survivors of an Australian wildfire that killed 172 people in the state of Victoria in 2009 found that two-thirds of survivors reported that they had carried out an existing disaster plan, while researchers found the majority of those who died either didn’t follow a disaster plan or couldn’t. Forecasters had warned that high temperatures were coming with very low humidity, and public alerts had gone out about the high fire risk. https://www.youtube.com/embed/Wq4VCI2JwgM?wmode=transparent&start=0 Residents had little time to evacuate as the Eaton Fire spread into Altadena, Calif., on Jan. 7, 2025.

How people perceive risks and the environmental and social cues around them – such as how much smoke they see, their neighbors’ choices or the wording of the notification – will directly affect the speed of their response.

Past experience with a disaster evacuation also has an impact. Rapid population growth in recent years in the wildland-urban interface – areas where human development meets wildfire-prone areas – has meant that more people with little or no experience with wildfires are living in fire-risk areas. Wildland areas also tend to have fewer evacuation routes, making mass evacuations more difficult and time-consuming.

Adding to the complexity is the fact that large wildfires are occurring in regions not historically prone to such events and during times of the year traditionally considered outside of wildfire season. This shift has left communities and emergency response teams grappling with unprecedented challenges, particularly when it comes to evacuations.

Computer models can help spot risks

To address these challenges, researchers are developing systems to help communities model how their residents are likely to respond in the event of a disaster.

The results can help emergency crews understand where bottlenecks are likely to occur along evacuation routes, depending on the timing of the notice and the movement of the fire. They can also help fire managers understand where neighborhoods may need to be notified faster or need more help evacuating.

My team at the Hazard and Climate Resilience Institute at Boise State University is working on one of these projects. We have been surveying communities across Idaho and Oregon to assess how people living in the wildland-urban interface areas perceive wildfire risks and prepare for evacuations.

Using those surveys, we can capture household-level decision data, such as which evacuation routes these residents would take, how many cars they plan to drive and where they would evacuate to.

We can also gauge how prepared residents would be to evacuate, or whether they would likely stay and try to defend their home instead.

With that data, we can simulate how long it will take emergency response teams to evacuate an entire community safely. The models could also show where difficulties with evacuations might be likely to arise and help residents understand how they can adjust their evacuation plans for a safer escape for everyone.

Bridging the gap between awareness and action

One of the key goals of this research is to bridge the gap between awareness and action.

While many residents in wildfire-prone areas understand the risks, translating that knowledge into concrete preparations remains a challenge. The concept of a “go bag,” for example, is widely promoted but often poorly understood. Essential items such as medications, important documents and pet supplies are frequently overlooked until it’s too late.

Clear and timely communication during wildfire crises is also essential. Evacuation warning messages such as “Ready, Set, Go!” are designed to prompt specific actions, but their effectiveness depends on residents understanding and trusting the system. Delayed responses or mixed signals can create confusion.

As wildfire risk rises for many communities, preparedness is no longer optional – it’s a necessity. Emergency notifications vary by state and county, so check your local emergency management office to understand what to expect and sign up for alerts. Being prepared can help communities limit some of the most devastating impacts of wildfires.

After a relatively quiet fall, there’s been another spike in cases of bird flu in Michigan.

When state officials announced on Dec. 16, 2024, that bird flu had been found in another poultry facility in Ottawa County, it was the first time the H5N1 virus had been detected in Michigan poultry in over six months. Since then, the U.S. Department of Agriculture has confirmed seven more outbreaks – in five commercial and two backyard flocks – in the state, the most recent in Oakland County.

Meanwhile, on Jan. 6, 2025, the Centers for Disease Control and Prevention reported the first human death from bird flu in the U.S., in Louisiana.

Bird flu is a complex and evolving disease with significant impact to the poultry and dairy industries. Since the beginning of the outbreaks in poultry and cattle, almost 135 million birds and more than 900 cattle herds have been affected nationwide. A significant number of wild animals – such as raccoon, skunks, foxes and bobcats – as well as marine mammals and domestic cats have also died from the virus.

Kimberly Dodd, dean of Michigan State University’s College of Veterinary Medicine, is an expert in outbreak response for emerging infectious diseases. Michigan was among the first states to see H5N1 outbreaks in commercial poultry and dairy facilities. Both state and federal officials have worked closely with the Michigan State University Veterinary Diagnostic Laboratory to identify newly infected herds, while continuing to provide surveillance for the virus in poultry and wild birds.

Dodd talked to The Conversation U.S. about the risks H5N1 presents to families, pets and livestock, and how researchers are working together to find ways to limit its spread.

What are Michigan researchers learning about the outbreak?

In the case of H5N1 in cows, scientists and animal health experts here in Michigan and around the country are working to understand a familiar disease in a novel species.

The transmission of the avian flu virus H5N1 to dairy cattle was first confirmed in March 2024 in Texas and has since spread to 15 other U.S. states, most recently California.

The virus impacts milk production and poses significant risks to other bird species, particularly domestic poultry as well as some mammals. The CDC has also confirmed mild cases in humans, and a fatal one in Louisiana in January 2025.

Diagnosticians at Michigan State University and the USDA’s National Animal Health Laboratory Network provide rapid diagnostics to identify infected herds and monitor the virus in wild birds and mammals, helping control the spread.

We’ve learned, based on sequencing the circulating viruses, that there is a specific virus strain or H5N1 genotype, B3.13, circulating in cows and poultry. Subtle changes over time in the genetic makeup of the virus points to a single spillover event. This means the virus likely spread from wild birds to a cow in Texas, and then spread from cow to cow. We also know that there is a separate H5N1 genotype, D1.1, that is currently circulating in wild birds and domestic poultry.

Researchers in our College of Veterinary Medicine are working with federal and state officials and farmers to determine how long cows produce infectious milk. The goal is to understand how cows are becoming infected within and across herds so that we can better mitigate the spread.

Why is it called bird flu if it sickens other animals too?

Influenza viruses affect many animals including humans, pigs, dogs and horses.

There are four types of influenza viruses: A, B, C and D, which are loosely defined by the species they can infect. Avian influenza viruses are considered influenza A viruses. Interestingly, influenza D viruses are the ones that primarily infect cattle. But the current H5N1 circulating in dairy cattle is the same influenza A virus as seen in the ongoing outbreak in birds.

This is of particular concern, as only influenza A viruses have been associated with human pandemics.

Avian influenza viruses circulate in wild birds but don’t typically cause them significant disease. While many avian influenza viruses can infect poultry, their behavior in those hosts classifies the virus as either highly pathogenic or low pathogenic. It’s important to note that this classification doesn’t necessarily indicate how easily it spreads or the likelihood that the virus will jump to other species.

The currently circulating strain is classified as highly pathogenic avian influenza, or HPAI, based on the high mortality it causes domestic poultry. One of the many unusual characteristics of the current outbreak is the high mortality seen in wild birds; as a result, we have seen many species of young carnivores and scavengers infected by the virus.

Infection in other species often requires exposure to a large amount of virus, or a compromised or underdeveloped immune system. These are typically “dead-end hosts.” They become infected but do not play a role in virus spread because either the animal dies or it becomes infected but not infectious.

The current outbreak of HPAI H5N1 has been ongoing since 2021. The outbreak is notable for its duration, wide geographic spread and unusual impact on nonpoultry species as well. It has caused significant illness and death in wild birds like ducks and geese, as well as mammals exposed to infected bird carcasses like cats and skunks.

However when the USDA unexpectedly confirmed that H5N1 was the cause of significant disease in dairy cattle in early 2024, it marked the first time that the virus was detected in U.S. dairy cattle.

What does the virus do to cattle?

Most cows infected with H5N1 recover on their own without treatment. Symptoms include fever and sluggishness. There is also decreased appetite and a significant drop in milk production in lactating cows, as the virus is concentrated in the mammary glands and milk.

There are three reasons to care about the ongoing H5N1 outbreak in dairy cattle:

First, the drop in milk production and the virus’s infectious nature create challenges for farmers to control the infection and lead to economic losses. In addition to the production losses, there are additional labor and supply costs to manage the outbreak in the herd, including separation and supportive care of sick cows. Workers also need to use personal protective equipment to prevent spread of the virus to healthy animals and to protect themselves from potential infection.

Second, dairy cows produce large amounts of the virus in milk, which is highly infectious. While pasteurization kills the virus, raw milk remains a major infection risk. Significant numbers of wild mammals and domestic cats on dairy farms have died from the virus after consuming raw milk. It also poses a risk to dairy workers.

The virus has also spread from dairy farms to poultry facilities, causing high bird mortality. Experts are exploring the possibility that clothing, shoes, trucks, equipment and other items that have been contaminated with raw milk containing the virus can lead to inadvertent, and lethal, exposure for poultry.

Third, prolonged circulation in cattle increases the risk of the virus adapting to mammals, including humans.

To monitor this risk, all H5N1-positive samples are sent to the USDA for genetic sequencing to identify mutations that may increase the virus’s ability to infect mammals and to provide important information about how the virus spreads within and between populations.

How do we manage H5N1 moving forward?

Biosecurity for poultry and dairy facilities is more critical than ever. Biosecurity measures include limiting visitors to farms and facilities; disinfecting tools, footwear and equipment; avoiding contact between infected and noninfected species; and isolating sick animals.

These measures play an important role in both containing the virus and keeping it away from other animals, properties and people.
