Asian longhorned tick: Here’s the deal with Delaware’s newest residents

Asian longhorned tick: Here’s the deal with Delaware’s newest residents

Jenna Miller, Wochit

  • Spending more time outdoors in the summers means more opportunities to encounter ticks.
  • Delaware is home to a handful of tick species. Knowing how to avoid them and how to treat tick bites will keep you safe, especially if you find yourself in wooded, grassy areas or backyards this year.
  • Lyme disease cases have seen an increase in recent years. In Delaware, hundreds of cases of Lyme disease are documented each year, with New Castle County reporting more than Kent and Sussex counties.

We’ve waited months for warm weather to grace us so we can spend more time outdoors, but with warm weather comes pesky ticks.

As more people hike through summer grasses, play in backyards and camp in forests, ticks are taking the opportunity to shimmy up pantlegs, crawl through sleeves or land in your hair to do what they do best: feed on your blood.

Reports show some states are seeing an increased presence of ticks this spring and summer, and with them, a surge in Lyme disease cases.

Here’s the rundown of everything we know about tick presence, Lyme disease cases and tick bites in Delaware, including prevention, symptoms and treatment.

Where are ticks found?

Ticks dwell in a variety of habitats and can be found in forest, meadows and wetlands throughout Delaware. They live in yards and residential areas, too, according to the Delaware Department of Natural Resources and Environmental Control.

Wooded areas, tall grass or brush — the edges where woods and lawn meet — are desirable spots for ticks, along with leaf litter, beneath ground-cover plants and around woodpiles or stone walls where small mammals live.

From there, ticks can latch onto the birds, mammals or reptiles they prey on and spread to other organisms.

Ticks are active year-round if temperatures are above freezing.

What types of ticks are in Delaware?

While there are hundreds of species of ticks found worldwide and dozens in the United States, only a handful are commonly spotted in the First State.

Lone Star tick

The most common tick species in the area is the Lone Star tick, identifiable by a white dot on its back. Found all over the state, it is more common in Kent and Sussex counties.

And while it may be tiny, it sure is mighty.

“It’s described as being an aggressive biter,” said Ashley Kennedy, tick biologist at the Delaware Department of Natural Resources and Environmental Control. “The bite itself can be very painful, very itchy.”

A bite from a Lone Star tick could trigger flu-like illness or, in rare cases, alpha-gal syndrome, in which a person develops an allergy to red meat and other products made from mammals such as dairy.

Black-legged/deer tick

The black-legged/deer tick is not as common as other species but is more likely to infect you if it bites you.

One of the illnesses it can cause is Lyme disease, a bacterial infection that can spread to your joints, heart and nervous system if not treated early.

American dog tick

The American dog tick is the least likely to make you sick, but a small percentage of them carry Rocky Mountain spotted fever, Kennedy said.

Rocky Mountain spotted fever is a bacterial disease that begins with symptoms such as fever, headache and rash. It can be deadly if it is not treated early on with the correct antibiotics.

Asian longhorned tick

The newest Delaware tick species, first spotted in 2019, is the Asian longhorned tick.

This invasive species has a female-only population that can lay eggs without needing a male and occasionally bites.

What is Lyme disease?

A major concern when it comes to ticks is Lyme disease, the most common vector-borne disease in the U.S. but just one of 16 tickborne illnesses that can be passed to humans.

It is transmitted to humans through the bite of an infected blacklegged tick and can lead to an infection of the joints, hearts and nervous system if left untreated. There is no evidence that the disease can be passed from person to person, according to the CDC.

Lyme disease accounts for approximately 30,000 of the reported tick-borne illnesses each year. The CDC suggests this number is actually closer to 476,000 due to underreporting when it comes to the disease.

Lyme disease in Delaware

In accordance with the Delaware Division of Public Health’s section of Epidemiology, Health Data and Informatics, the entity cannot disclose the current number of Lyme disease cases in Delaware, said Laura Matusheski, media relations coordinator for DPH.

“Delaware sees cases of Lyme disease in all three counties year-round and continues to monitor disease trends. People who spend time outdoors in grassy or wooded environments are at risk for increased exposure,” the Division of Public Health stated.

The CDC defines Delaware as a high-incidence state for Lyme disease, ranking it among the top 10 states for cases in the United States.

DPH tracks yearly totals for the number of Lyme disease cases reported in Delaware, and the number of cases per 100,000 people per year over the last five years are as follows:

  • In 2018, there were 540 cases of Lyme disease statewide per 100,000 people. New Castle County contributed 302 cases, followed by Kent County at 87 and Sussex County at 131.
  • In 2019, there were 659 cases statewide. New Castle County contributed 437, followed by 86 in Kent County and 136 in Sussex County.
  • In 2020, 353 cases were reported statewide. New Castle County contributed 249, Kent County contributed 43 and Sussex County contributed 161.
  • In 2021, 354 cases were reported statewide. New Castle County reported 250, Kent County reported 40 and Sussex County reported 64.
  • In 2022, the most recent year with data, 385 statewide cases were reported. New Castle County documented 253, Kent County documented 64 and Sussex County documented 68.

As the data shows, New Castle County has reported the highest incidence rates of Lyme disease compared with Kent and Sussex counties, at time documenting cases that are four times greater than throughout the rest of the state.

What are the symptoms of Lyme disease?

Lyme disease bacterium can infect several parts of the body and cause different symptoms at different times. Some of these symptoms may be nonspecific and resemble other diseases, according to the Division of Public Health.

Early symptoms of Lyme disease include:

  • Headache.
  • Fatigue.
  • An expanding red rash, commonly referred to as a bulls-eye rash. It can appear anywhere on the body and be warm to the touch but is usually not itchy or painful. Not all affected individuals will develop a rash.
  • Fever and/or chills.
  • Muscle and joint aches.

If left untreated, the following symptoms can occur:

  • Heart palpitations and dizziness.
  • Severe joint pain and swelling, usually in large joints like the knees.
  • Severe headaches and neck stiffness due to meningitis.
  • Loss of muscle tone on one or both sides of the face, called “Bell’s palsy.”
  • Neurological problems like numbness or tingling in extremities and problems with concentration and short-term memory.

If you think you have Lyme disease, contact your health care provider. Most cases of Lyme disease can be cured with antibiotics taken over the course of a few weeks, but the severity of symptoms and subsequent treatment may vary this timeline.

Some patients experience chronic symptoms months and years after the infection has cleared.

How to keep ticks away from your home

When it comes to keeping ticks away from you and your home, there are several ways you can decrease the presence of ticks on your property.

Keeping your grass mowed and removing leaf litter, brush and tall weeds from the edges of your lawn are routine ways to keep ticks out.

Other tactics from the CDC include:

  • Moving firewood, birdhouses and feeders away from your home. Wood should be stacked in a dry area.
  • Using plants that do not attract deer or exclude deer by using various types of fencing. Deer are the main food source for adult ticks.
  • Creating a 3-foot or wider wood chip, gravel or mulch barrier between your property and the woods.
  • Removing old furniture or trash, which ticks love to hide in, from your yard.
  • Keeping playground equipment, patios and decks away from yard edges and trees, instead placing them in sunny locations, if possible.

Tick bite prevention

Knowing where ticks usually dwell is the first step in preventing an encounter with them.

If you find yourself in a moist and humid environment that is near wooded or grassy areas, there are extra steps you can take to stay safe while in these places.

For those of you tasked with wading through fall leaves or tidying up the shrubs, wear light-colored clothing to allow you to see ticks crawling on you.

If you find yourself in an area ripe for ticks, be sure to wear long sleeves and pants. Tuck your pant legs into your socks and consider wearing a hair tie on your sleeves to prevent ticks from crawling into the openings of your clothes.

Other ways to prevent tick bites, according to DPH, include:

  • Applying tick repellent that contains DEET. This lasts only a few hours and needs to be reapplied as necessary. Adults should use a repellent containing less than 50% DEET. Children’s repellents should contain less than 30% DEET. Do not use repellents with DEET on infants under 2 months old.
  • Searching your body for ticks during and after an outing. Be thorough when checking under your arms, inside your belly button, in and around your ear, behind the knees, between the legs, around the waist and in and around all head and body hair.
  • Checking children and pets for ticks. Your beloved pet probably has no clue a tick just latched onto him for a free ride into the house after a round of fetch. Giving your kids another look after they check for ticks can’t hurt either.

Symptoms of a tick bite

If you suspect you have been bitten by a tick, many tickborne illnesses share similar signs and symptoms.

See your health care provider if you develop the following symptoms within a few weeks of a tick bite:

  • Fever or chills: All tickborne diseases can cause fever.
  • Rash: Lyme disease, Southern tick-associated rash illness, Rocky Mountain spotted fever, ehrlichiosis and tularemia can cause distinctive rashes.
  • Aches and pains: Tickborne diseases can cause headaches, fatigue and muscle aches.

Tick bite treatment

After spending the day outdoors, your tick check might alert you to some unwelcome hitchhikers on your body.

If you discover a tick on you or your pets, do not use home remedies like petroleum jelly or hot matches to remove the ticks. They do not work, the Division of Public Health said.

Instead, use these steps to help rid yourself of ticks:

  • Use fine-tipped tweezers or shield your fingers with a paper towel, rubber gloves or a tissue to remove ticks. Do not pick at them with bare hands.
  • Grasp the tick close to the skin surface and pull upward with steady, even pressure.
  • Do not squeeze, crush or puncture the body of the tick. Its fluids, such as saliva, body fluids and gut contents, may contain infectious germs.
  • After removing the tick, clean the removal spot with an antiseptic or soap water. Don’t forget to wash your hands afterward!

Health Canada approves updated Moderna COVID-19 vaccine

Published

 on

 

TORONTO – Health Canada has authorized Moderna’s updated COVID-19 vaccine that protects against currently circulating variants of the virus.

The mRNA vaccine, called Spikevax, has been reformulated to target the KP.2 subvariant of Omicron.

It will replace the previous version of the vaccine that was released a year ago, which targeted the XBB.1.5 subvariant of Omicron.

Health Canada recently asked provinces and territories to get rid of their older COVID-19 vaccines to ensure the most current vaccine will be used during this fall’s respiratory virus season.

Health Canada is also reviewing two other updated COVID-19 vaccines but has not yet authorized them.

They are Pfizer’s Comirnaty, which is also an mRNA vaccine, as well as Novavax’s protein-based vaccine.

These people say they got listeria after drinking recalled plant-based milks

Published

 on

 

TORONTO – Sanniah Jabeen holds a sonogram of the unborn baby she lost after contracting listeria last December. Beneath, it says “love at first sight.”

Jabeen says she believes she and her baby were poisoned by a listeria outbreak linked to some plant-based milks and wants answers. An investigation continues into the recall declared July 8 of several Silk and Great Value plant-based beverages.

“I don’t even have the words. I’m still processing that,” Jabeen says of her loss. She was 18 weeks pregnant when she went into preterm labour.

The first infection linked to the recall was traced back to August 2023. One year later on Aug. 12, 2024, the Public Health Agency of Canada said three people had died and 20 were infected.

The number of cases is likely much higher, says Lawrence Goodridge, Canada Research Chair in foodborne pathogen dynamics at the University of Guelph: “For every person known, generally speaking, there’s typically 20 to 25 or maybe 30 people that are unknown.”

The case count has remained unchanged over the last month, but the Public Health Agency of Canada says it won’t declare the outbreak over until early October because of listeria’s 70-day incubation period and the reporting delays that accompany it.

Danone Canada’s head of communications said in an email Wednesday that the company is still investigating the “root cause” of the outbreak, which has been linked to a production line at a Pickering, Ont., packaging facility.

Pregnant people, adults over 60, and those with weakened immune systems are most at risk of becoming sick with severe listeriosis. If the infection spreads to an unborn baby, Health Canada says it can cause miscarriage, stillbirth, premature birth or life-threatening illness in a newborn.

The Canadian Press spoke to 10 people, from the parents of a toddler to an 89-year-old senior, who say they became sick with listeria after drinking from cartons of plant-based milk stamped with the recalled product code. Here’s a look at some of their experiences.

Sanniah Jabeen, 32, Toronto

Jabeen says she regularly drank Silk oat and almond milk in smoothies while pregnant, and began vomiting seven times a day and shivering at night in December 2023. She had “the worst headache of (her) life” when she went to the emergency room on Dec. 15.

“I just wasn’t functioning like a normal human being,” Jabeen says.

Told she was dehydrated, Jabeen was given fluids and a blood test and sent home. Four days later, she returned to hospital.

“They told me that since you’re 18 weeks, there’s nothing you can do to save your baby,” says Jabeen, who moved to Toronto from Pakistan five years ago.

Jabeen later learned she had listeriosis and an autopsy revealed her baby was infected, too.

“It broke my heart to read that report because I was just imagining my baby drinking poisoned amniotic fluid inside of me. The womb is a place where your baby is supposed to be the safest,” Jabeen said.

Jabeen’s case is likely not included in PHAC’s count. Jabeen says she was called by Health Canada and asked what dairy and fresh produce she ate – foods more commonly associated with listeria – but not asked about plant-based beverages.

She’s pregnant again, and is due in several months. At first, she was scared to eat, not knowing what caused the infection during her last pregnancy.

“Ever since I learned about the almond, oat milk situation, I’ve been feeling a bit better knowing that it wasn’t something that I did. It was something else that caused it. It wasn’t my fault,” Jabeen said.

She’s since joined a proposed class action lawsuit launched by LPC Avocates against the manufacturers and sellers of Silk and Great Value plant-based beverages. The lawsuit has not yet been certified by a judge.

Natalie Grant and her seven year-old daughter, Bowmanville, Ont.

Natalie Grant says she was in a hospital waiting room when she saw a television news report about the recall. She wondered if the dark chocolate almond milk her daughter drank daily was contaminated.

She had brought the girl to hospital because she was vomiting every half hour, constantly on the toilet with diarrhea, and had severe pain in her abdomen.

“I’m definitely thinking that this is a pretty solid chance that she’s got listeria at this point because I knew she had all the symptoms,” Grant says of seeing the news report.

Once her daughter could hold fluids, they went home and Grant cross-checked the recalled product code – 7825 – with the one on her carton. They matched.

“I called the emerg and I said I’m pretty confident she’s been exposed,” Grant said. She was told to return to the hospital if her daughter’s symptoms worsened. An hour and a half later, her fever spiked, the vomiting returned, her face flushed and her energy plummeted.

Grant says they were sent to a hospital in Ajax, Ont. and stayed two weeks while her daughter received antibiotics four times a day until she was discharged July 23.

“Knowing that my little one was just so affected and how it affected us as a family alone, there’s a bitterness left behind,” Grant said. She’s also joined the proposed class action.

Thelma Feldman, 89, Toronto

Thelma Feldman says she regularly taught yoga to friends in her condo building before getting sickened by listeria on July 2. Now, she has a walker and her body aches. She has headaches and digestive problems.

“I’m kind of depressed,” she says.

“It’s caused me a lot of physical and emotional pain.”

Much of the early days of her illness are a blur. She knows she boarded an ambulance with profuse diarrhea on July 2 and spent five days at North York General Hospital. Afterwards, she remembers Health Canada officials entering her apartment and removing Silk almond milk from her fridge, and volunteers from a community organization giving her sponge baths.

“At my age, 89, I’m not a kid anymore and healing takes longer,” Feldman says.

“I don’t even feel like being with people. I just sit at home.”

Jasmine Jiles and three-year-old Max, Kahnawake Mohawk Territory, Que.

Jasmine Jiles says her three-year-old son Max came down with flu-like symptoms and cradled his ears in what she interpreted as a sign of pain, like the one pounding in her own head, around early July.

When Jiles heard about the recall soon after, she called Danone Canada, the plant-based milk manufacturer, to find out if their Silk coconut milk was in the contaminated batch. It was, she says.

“My son is very small, he’s very young, so I asked what we do in terms of overall monitoring and she said someone from the company would get in touch within 24 to 48 hours,” Jiles says from a First Nations reserve near Montreal.

“I never got a call back. I never got an email”

At home, her son’s fever broke after three days, but gas pains stuck with him, she says. It took a couple weeks for him to get back to normal.

“In hindsight, I should have taken him (to the hospital) but we just tried to see if we could nurse him at home because wait times are pretty extreme,” Jiles says, “and I don’t have child care at the moment.”

Joseph Desmond, 50, Sydney, N.S.

Joseph Desmond says he suffered a seizure and fell off his sofa on July 9. He went to the emergency room, where they ran an electroencephalogram (EEG) test, and then returned home. Within hours, he had a second seizure and went back to hospital.

His third seizure happened the next morning while walking to the nurse’s station.

In severe cases of listeriosis, bacteria can spread to the central nervous system and cause seizures, according to Health Canada.

“The last two months have really been a nightmare,” says Desmond, who has joined the proposed lawsuit.

When he returned home from the hospital, his daughter took a carton of Silk dark chocolate almond milk out of the fridge and asked if he had heard about the recall. By that point, Desmond says he was on his second two-litre carton after finishing the first in June.

“It was pretty scary. Terrifying. I honestly thought I was going to die.”

Cheryl McCombe, 63, Haliburton, Ont.

The morning after suffering a second episode of vomiting, feverish sweats and diarrhea in the middle of the night in early July, Cheryl McCombe scrolled through the news on her phone and came across the recall.

A few years earlier, McCombe says she started drinking plant-based milks because it seemed like a healthier choice to splash in her morning coffee. On June 30, she bought two cartons of Silk cashew almond milk.

“It was on the (recall) list. I thought, ‘Oh my God, I got listeria,’” McCombe says. She called her doctor’s office and visited an urgent care clinic hoping to get tested and confirm her suspicion, but she says, “I was basically shut down at the door.”

Public Health Ontario does not recommend listeria testing for infected individuals with mild symptoms unless they are at risk of developing severe illness, such as people who are immunocompromised, elderly, pregnant or newborn.

“No wonder they couldn’t connect the dots,” she adds, referencing that it took close to a year for public health officials to find the source of the outbreak.

“I am a woman in my 60s and sometimes these signs are of, you know, when you’re vomiting and things like that, it can be a sign in women of a bigger issue,” McCombe says. She was seeking confirmation that wasn’t the case.

Disappointed, with her stomach still feeling off, she says she decided to boost her gut health with probiotics. After a couple weeks she started to feel like herself.

But since then, McCombe says, “I’m back on Kawartha Dairy cream in my coffee.”

B.C. mayors seek ‘immediate action’ from federal government on mental health crisis

Published

 on

 

VANCOUVER – Mayors and other leaders from several British Columbia communities say the provincial and federal governments need to take “immediate action” to tackle mental health and public safety issues that have reached crisis levels.

Vancouver Mayor Ken Sim says it’s become “abundantly clear” that mental health and addiction issues and public safety have caused crises that are “gripping” Vancouver, and he and other politicians, First Nations leaders and law enforcement officials are pleading for federal and provincial help.

In a letter to Prime Minister Justin Trudeau and Premier David Eby, mayors say there are “three critical fronts” that require action including “mandatory care” for people with severe mental health and addiction issues.

The letter says senior governments also need to bring in “meaningful bail reform” for repeat offenders, and the federal government must improve policing at Metro Vancouver ports to stop illicit drugs from coming in and stolen vehicles from being exported.

Sim says the “current system” has failed British Columbians, and the number of people dealing with severe mental health and addiction issues due to lack of proper care has “reached a critical point.”

Vancouver Police Chief Adam Palmer says repeat violent offenders are too often released on bail due to a “revolving door of justice,” and a new approach is needed to deal with mentally ill people who “pose a serious and immediate danger to themselves and others.”
