Spring’s warmer weather lures people outdoors – and into possible contact with ticks that spread Lyme disease.

Already, the 2026 tick season is booming. On April 23, the Centers for Disease Control and Prevention warned that emergency room visits due to tick bites are at their highest level since 2017. That may portend an especially severe season for Lyme disease and other tick-borne illnesses.

State health departments reported more than 89,000 cases of Lyme disease in 2023, the last year for which data is available. But public health experts believe that close to 500,000 people in the U.S. get Lyme disease every year.

As an infectious disease doctor with experience treating some of this infection’s long-term outcomes, I know that Lyme disease can be tricky because people often don’t notice tick bites and may overlook early symptoms of an infection. But left untreated, the infection can cause serious lingering – and even permanent – health issues.

Here’s what you need to know about Lyme disease to stay safe this season:

What causes Lyme disease?

Lyme disease, named after the Connecticut town where the disease was first identified in 1975, is caused by a group of bacteria called Borrelia – most often, the species Borrelia burgdorferi.

Deer ticks – also called black-legged ticks, and members of a group called Ixodes – transmit the disease after feeding on an infected animal, usually a bird, mouse or deer. When they then bite a person, they can transmit the bacteria into the person’s bloodstream.
Usually, the tick must attach for 24-48 hours to transmit the bacteria causing Lyme disease.

Where and when does Lyme disease occur?

Lyme disease can occur in most regions where deer ticks live.

These ticks are most active in late spring, summer and fall – usually April to November in most regions. They emerge when the temperature is above freezing. In years when winter is shorter, ticks can emerge earlier. And they may be active year-round in regions where freezing temperatures are rare.

Approximately 90% of U.S. cases are reported from states in the Northeast, mid-Atlantic from Virginia to eastern Canada, and Upper Midwest regions including Wisconsin, Michigan and Minnesota. A few cases occasionally pop up in California, Oregon and Washington.

Since 1995, the incidence of Lyme disease in the U.S. has almost doubled.

Warmer weather and changes in rainfall patterns now allow ticks to survive in new regions of the country – and for longer periods. But even in regions where ticks lived before, Lyme disease has become more common due to increases in deer populations. As woodland areas are increasingly being developed, it may be bringing the habitat of deer and mice closer to people, increasing the risk of transmission.

Lyme disease symptoms to watch for

Early symptoms of Lyme disease – fever, muscle aches and fatigue – generally emerge within three to 30 days after a tick bite. Another classic symptom in the first month is a target or bull’s eye rash at the site of tick bite, which occurs in about 70% to 80% of cases.

Other rashes following a tick bite can also occur. Some may be due to irritation from the bite, and not necessarily an infection.

If you know you’ve had a tick bite and experience flu-like symptoms – or if you see a bull’s-eye rash, whether you know you were bitten or not – it’s important to check with your healthcare provider about whether you should be treated with antibiotics.

A blood test for antibodies can help confirm the infection, but it can sometimes yield a false negative result, particularly in the first couple of weeks of the disease.

In most people, the rash goes away on its own. However, treatment may shorten its duration and is important for preventing other symptoms. A two- to four-week course of antibiotics can generally treat Lyme disease. Severe cases might require intravenous antibiotics.

A promising new vaccine for Lyme disease is currently being tested. In March 2026, Pfizer, the pharmaceutical company developing it, announced that in a late-stage study, the vaccine prevented the disease in 70% of people who received it.

Later Lyme symptoms

If left untreated, the bacteria that causes Lyme can spread, potentially causing longer-term symptoms. About 60% of people who get Lyme disease and don’t treat it can develop arthritis.

In rare cases, Lyme disease can also affect the heart and the nervous system. Inflammation in the brain or the tissues surrounding it, called meninges, can cause headaches and neck pain, as well as balance issues and memory and behavior changes. It can also cause nerve damage that results in numbness, tingling and muscle weakness.

These symptoms can appear right away or much later – sometimes months to years after infection. And in cases where the disease wasn’t promptly treated, late-stage symptoms can linger even after antibiotics kill the bacteria.

Scientists don’t fully understand why, but one intriguing study found that some particles from the bacteria’s cell wall leak into the joints and can persist after treatment, spurring ongoing inflammation and arthritis symptoms.

Another reason for Lyme’s long-term effects is that it can trigger autoimmune disease, which is when the immune system attacks its own cells. What’s more, because the nervous system may be particularly sensitive to damage caused by the bacteria and related inflammation, it may take an especially long time to heal. In some situations, the damage could be permanent.

Preventing Lyme disease

Until a vaccine becomes available, there are steps you and your family can take to help protect against Lyme disease:

• Use tick and insect repellents such as DEET and picaridin, which can be applied to skin, and permethrin, which is sprayed onto clothing, to keep ticks at bay. Treating clothing with permethrin may be especially beneficial, since the substance withstands several washes.
• Wear long-sleeve shirts and pants while you are gardening, hiking or walking through grass or woods to prevent tick bites. Wearing light-colored clothes makes ticks more visible, and tucking your pants into your socks can also prevent the little buggers from traveling from your pants, shoes and socks onto your legs.
• Remove your outdoor clothes immediately. Washing and drying clothes at high temperature can help kill any ticks that managed to hitch a ride. And a quick shower immediately after spending time outdoors can wash ticks off the skin before they have a chance to attach.
• If you spend time outdoors, perform daily tick checks, paying special attention to warm areas like your armpits, neck, ears and underwear line. If you find a tick attached, pull it off with tweezers, holding them perpendicular to the skin.
• If you find a tick that may have been on the skin for more than 36 hours, ask your healthcare provider whether a dose of preventive antibiotics – generally given within 72 hours of the bite – would be appropriate.

(Feature Impact) You may have mastered the core subjects like math and grammar in school, but financial literacy – or understanding the basics of money management in order to help you make better financial decisions – often goes overlooked before adulthood. It’s not so much a course of study as it is a plan of action.

Financial literacy in the United States has remained stagnant at generally low levels for several years, according to research from TIAA Institute and the Global Financial Literacy Excellence Center, with even lower levels among Gen Z. Yet greater financial literacy – including key aspects such as goal-setting, budgeting, saving, credit management and investing – is strongly linked to better financial outcomes, including lower rates of debt constraint and financial fragility.

While emboldening yourself to understand financial terms can be a little overwhelming at first, once you have a grasp of basic concepts you can begin to get a handle on your money and make better financial decisions. Simply put: When you understand how to earn, save, spend and invest wisely, you aren’t just building a stable future for yourself, but your family and community as well.

From nonprofit partnerships to volunteer-led programs and fee online resources, Schwab and its employees help millions of people every year build the knowledge and confidence to take charge of their financial futures by serving as board members, mentors, role models and educators.

Because financial health is a lifelong journey, the earlier people learn vital money skills, the better. That’s why the financial advisory services provider develops education programs geared toward kids that continue into adulthood, helping people no matter where they are on their journeys.

Talk Money

It’s never too early to start a conversation about financial literacy. Having teens identify goals that are important to them – such as concert tickets or a first car – can kickstart coversations about money. Working with your child (and a financial advisor, if necessary) on a plan for saving to realize those goals can serve as a jumping off point. After achieving some success, their enthusiasm may grow, which is a powerful motivator to keep saving.

Support School Initiatives and Programs

Outreach programs that empower young people to make smart financial decisions is key to a bright future. Programs like Money Matters – Schwab’s flagship financial education program utilized by the Boys & Girls Clubs of America – gives young people hands-on experience with all aspects of money and investing.

This example, and others, don’t just include program funding – they build partnerships that create impact and opportunity with national collaborations that reach more than 17 million youth annually, empowering young people with the tools and confidence to make smart financial decisions for life.

Spread the Financial Love

Championing financial literacy empowers everyone – individuals, families and communities. By serving as a board member, mentor, role model or educator to help bring financial literacy to others in your community, you can supply the tools and knowledge to lead programs that focus on giving back, empowering future generations in countless ways.

The future of transportation in Los Angeles has officially arrived.

LA Metro’s D Line Extension Phase 1 Officially Opens

The Los Angeles County Metropolitan Transportation Authority (Metro) officially opened Section 1 of the long-awaited D Line Subway Extension on May 8, 2026, expanding underground rail service westward through the historic Mid-Wilshire corridor and into Beverly Hills.

The 3.92-mile extension is one of Metro’s most ambitious transit infrastructure projects and marks a major milestone in Los Angeles public transportation. The new section extends subway service beyond the current Wilshire/Western station in Koreatown and introduces three new underground stations:

• Wilshire/La Brea
• Wilshire/Fairfax
• Wilshire/La Cienega

The expansion is part of Metro’s larger “Twenty-Eight by ’28” initiative designed to improve mobility across the region ahead of the 2028 Olympic and Paralympic Games.

Downtown Los Angeles to Beverly Hills in About 20 Minutes

With the extension now open, riders can travel from Union Station in Downtown Los Angeles to Beverly Hills in approximately 20 minutes with no transfers required.

The D Line extension is expected to significantly improve travel along the heavily congested Wilshire Boulevard corridor, offering commuters, visitors and residents a faster and more reliable alternative to driving.

“Traveling through Mid-Wilshire to experience the culture, cuisine and commerce across diverse neighborhoods will be easier, faster and more accessible,” said Fernando Dutra, Metro Board Chair and City of Whittier Council Member.

Metro CEO Stephanie Wiggins also highlighted the importance of the project in connecting Angelenos to some of the city’s most iconic destinations.

“Angelenos and visitors alike will love the extended service from Downtown Los Angeles to Beverly Hills, delivering greater access to the iconic and culturally diverse communities, institutions and destinations that define the deep history along Wilshire Boulevard,” Wiggins said.

New Stations Connect Riders to Cultural Landmarks

Wilshire/La Brea Station

Located near Hancock Park and the western edge of Koreatown, the station provides access to cultural and entertainment destinations including:

• Korean Cultural Center
• Marciano Art Foundation
• Ebell Theater
• Popular restaurants including Republique and Sycamore Kitchen

Wilshire/Fairfax Station

Known as the heart of Museum Row, this station serves some of Los Angeles’ most recognizable cultural institutions and attractions, including:

• Los Angeles County Museum of Art (LACMA)
• Academy Museum of Motion Pictures
• Petersen Automotive Museum
• La Brea Tar Pits
• The Grove
• Original Farmers Market

The station also connects neighborhoods including Little Ethiopia, Park La Brea and the historic Fairfax District.

Wilshire/La Cienega Station

Serving as the eastern gateway to Beverly Hills, the station provides convenient access to Restaurant Row and destinations including the Beverly Center.

A Major Milestone for Los Angeles Transit

The D Line extension has been decades in the making and is widely considered one of the most important transit projects in Los Angeles history.

The project was funded primarily through Measure R, the voter-approved transportation sales tax passed in 2008, along with substantial federal funding support that included:

• $1.25 billion Full Funding Grant Agreement (FFGA)
• $66.4 million supplemental New Starts funding
• $749.3 million TIFIA loan

All three stations feature modern amenities including public artwork, enhanced lighting, cell phone service, bicycle hubs and improved pedestrian access.

Metro officials hope the extension will encourage more residents and visitors to use public transportation while helping reduce roadway congestion ahead of major international events scheduled for Los Angeles later this decade.

What’s Next for the D Line?

Construction is already underway on future phases of the D Line extension.

Phase 2 will continue west into Beverly Hills and Century City, while Phase 3 will eventually extend subway service to UCLA and the West Los Angeles VA campus.

Once completed, the D Line will provide a direct subway connection between Downtown Los Angeles and the Westside, dramatically reshaping mobility across one of Southern California’s busiest corridors.
