What Is the Flu Season?<\/h2>\n

Flu season is the time of year when the flu spreads more easily in our communities. In California and across the country, this usually happens during the cooler months when we spend more time indoors and germs can pass more quickly from person to person.<\/p>\n

Flu season is a yearly cycle that gives health care providers time to prepare and protect our communities. By tracking early signs of the flu and offering vaccines at the right time, they can help slow the spread and lessen the impact of outbreaks.<\/p>\n

The flu mostly spreads through droplets released when someone coughs, sneezes, or even talks close by. These droplets can reach the nose or mouth of others and cause infection. Understanding how the flu spreads can help keep your family safer. You can learn more in our flu transmission guide<\/a>.<\/p>\n

When Is Flu Season in California?<\/h2>\n

In California, flu season usually starts in October and lasts through May. As the weather cools down, flu activity rises, with the biggest spike happening between December and February. This is when doctors see the most flu-related visits, so it\u2019s a great time to stay mindful of symptoms and make sure your vaccinations are current.<\/p>\n

Many families also wonder if you can catch the flu outside these months, like in the summer. The answer is yes, it\u2019s possible, but it doesn\u2019t happen very often. Flu viruses are around all year, just at much lower levels. Off-season cases can occur, especially for people with weaker immune systems or those who travel. Still, these cases are far less common than what we see during the typical flu season in California.<\/p>\n

Why Does the Flu Get Worse in the Winter?<\/h2>\n

Every year, flu season seems to hit hardest in the middle of winter, and it\u2019s not just by chance. Cooler weather, drier air, and more time spent indoors all make it easier for the flu to spread. Our immune systems can also be a bit weaker during the winter because we get less sunlight and vitamin D. All of these factors together help explain why flu cases climb during the colder months.<\/p>\n

More Time Indoors<\/h3>\n

When the weather gets colder, we all spend more time indoors at home, in school, or at work. While it\u2019s cozy inside, being in close quarters makes it easier for the flu to spread from person to person.<\/p>\n

The flu spreads mostly through tiny droplets that are released when someone who is sick talks, coughs, or sneezes. In the winter, these droplets can hang in the air a little longer, especially in spaces that are not well-ventilated. Busy indoor places like schools, buses, and workplaces make it easy for the flu to move from one person to many. The CDC<\/a> notes that these close-contact environments play a big role in how the flu spreads through communities each year.<\/p>\n

The Virus Survives Better in Cold, Dry Air<\/h3>\n

Cold, dry winter air does more than make us reach for a jacket. It also helps the flu virus survive longer. Studies show that in low temperatures, the flu virus develops a tougher outer shell that protects it as it spreads from person to person. In warmer, more humid air, that shell breaks down more quickly, which makes the virus less likely to spread.<\/p>\n

In winter, this means that droplets from a cough or sneeze can stay infectious for a longer period of time, especially in heated indoor spaces where the air is dry. Research from NIH.gov<\/a> confirms that the flu virus stays stronger and more contagious in these cold, dry conditions.<\/p>\n

When you combine more time spent indoors with a virus that survives better in winter air, flu season becomes much easier to understand. This is why health experts encourage early vaccination and good prevention habits. Preparing before flu cases rise is one of the best ways to protect your family.<\/p>\n

The 2025-2026 Flu Vaccine: What Our Community Needs to Know<\/h2>\n

\"Person<\/p>\n

As the 2025\u20132026 flu season approaches, getting your flu shot is one of the best ways to keep yourself and your family healthy. Each year, medical experts review the latest flu strains and update the vaccine to match what is most likely to spread. This year\u2019s vaccine is designed to provide strong protection and help keep our San Diego and Riverside County communities healthy.<\/p>\n

One Shot, Three Strains of Protection (Trivalent Vaccine)<\/h3>\n

The 2025\u20132026 flu vaccines are trivalent, which simply means they cover three different flu strains that health experts believe will be most common this year. This gives you wider protection and can help lessen symptoms if you do get sick.<\/p>\n

You might also wonder if it is possible to get the flu more than once in a season. The answer is yes. Since multiple strains spread at the same time, a person can catch one strain early and a different one later. The annual flu shot helps guard against several strains at once. The Mayo Clinic Health System<\/a> notes that getting vaccinated is the most reliable way to protect yourself and others.<\/p>\n

When Is the Best Time to Get Vaccinated?<\/h3>\n

Flu vaccines are available for several months, but the best time to get your shot is early fall.<\/p>\n

Ideally, get your flu shot in early fall, but if you haven\u2019t been vaccinated yet, it\u2019s still a good idea to get it as soon as possible. It takes about two weeks for your body to build protection, and flu can continue to circulate into spring.<\/p>\n

New Vaccine Options Available This Year<\/h3>\n

This year, there are more vaccine options to help make flu protection easier for everyone. FluMist<\/strong> is a nasal spray available for people ages 2 to 49 who prefer to skip the shot. Flublok<\/strong> is another option for anyone ages 9 and older, especially those with egg allergies or who want a highly purified vaccine. With these choices, more people can find the option that feels right for them.<\/p>\n

If you\u2019re not sure which vaccine is best for you or your family, our TrueCare providers are here to help. We offer guidance based on age, health needs, and personal preferences so you feel confident in your decision.<\/p>\n

Beyond the Vaccine: More Ways to Stay Healthy<\/h2>\n

Getting your flu shot is the strongest way to protect yourself during flu season, but a few everyday habits can make your protection even better. Simple steps can greatly reduce the spread of illness, especially for those who are more vulnerable like young children, older adults, and people with ongoing health conditions.<\/p>\n

One of the easiest habits to maintain is regular handwashing<\/strong>. Wash your hands with soap and water for at least 20 seconds, especially after coughing, sneezing, or spending time in public places. If you do not have access to soap and water, an alcohol-based hand sanitizer is a good backup.<\/p>\n

It is also important to stay home when you are feeling sick<\/strong>, even if symptoms are mild. Resting helps you recover faster and keeps others from getting exposed. If you do need to be around others, try to cover your coughs and sneezes and consider wearing a mask in crowded spaces to reduce the chance of spreading germs.<\/p>\n

These small actions go a long way in keeping our communities healthy each year. For more tips on prevention, symptoms, and what to do if you get sick, explore our\u00a0flu prevention and treatment guide<\/a>.<\/p>\n

Who Should Be Extra Cautious During Flu Season?<\/h2>\n

Every flu season brings a new wave of illness, and the flu does not affect everyone the same way. Many people have mild symptoms, but others can become seriously ill or even require hospitalization. High-risk groups tend to see more severe cases, which is why extra care and prevention are so important for them and the people around them.<\/p>\n

High-Risk Groups for Severe Illness<\/h3>\n

People at greater risk for complications from the flu include:<\/span><\/p>\n

    \n
  • Adults 65 and older<\/b>, whose immune systems naturally weaken with age.<\/span><\/li>\n
  • Young children<\/b>, especially those under 5, who have developing immune defenses.<\/span><\/li>\n
  • Pregnant people<\/b>, who experience immune and respiratory changes that increase vulnerability.<\/span><\/li>\n
  • Individuals with chronic health conditions<\/b> such as asthma, diabetes, or heart disease, whose bodies may have a harder time fighting infection.<\/span><\/li>\n<\/ul>\n

    For people in these groups, the flu can be much more serious and even life-threatening. That is why prevention through vaccination, healthy habits, and early care matters <\/strong>so much. Families and caregivers can help by getting vaccinated too, creating an extra layer of protection for loved ones who are at higher risk.<\/p>\n
