Watch out for this new invasive tick. It could saddle you with a little-known, debilitating infection
An invasive tick species is creeping its way into more parts of the country, as warming temperatures help it spread a little-known infection that can leave people with debilitating symptoms, and in rare cases, dead. In May, scientists at the Connecticut Agricultural Experiment Station in New Haven discovered for the first time that the longhorned tick had become a carrier for the bacteria that causes the Ehrlichiosis infection. With cases already on the rise, that was a big cause of concern. 'I am afraid to say that it is a storm brewing,' said Goudarz Molaei, the director of the lab's tick-testing program. 'Climate change eventually will almost eliminate winter in our region. And this tick, like other tick species, will be active year round.' Warming temperatures, which have already translated into shorter winters, allow the longhorned tick and other tick species to wake up early from hibernation, increasing the risk of getting bitten. The longhorned tick, which is native to East Asia, first invaded places like Australia, New Zealand and the Pacific Islands. It has now been detected in at least 21 states in the U.S. with Michigan reporting its first sighting at the end of June. Researchers aren't sure how the tick made it to the U.S., but it's likely it arrived on the backs of imported livestock or other animals. In 2017, scientists identified the country's first longhorned tick in New Jersey, though it's likely the species has been in the U.S. since at least 2010. 'The fact it was here for so long without us actually knowing about it was really a wakeup call,' said Dana Price, an associate research professor in the department of entomology at Rutgers University. Modeling indicates areas from southern Canada throughout the continental U.S. are environmentally suitable to the longhorned tick. That means the threat is two-fold: The longhorned's geographic range is expanding and so is the time that they're active and able to transmit disease, scientists said. Ehrlichiosis is becoming so prevalent that there is a region of the country unofficially named after it: The 'Ehrlichiosis Belt' stretches from as far north as Connecticut and New York to as far west as Arkansas. The lone star and blacklegged ticks have long carried Ehrlichia chaffeensis, the bacteria that causes Ehrlichiosis. The infection sends about 60% of patients to the hospital and claims the lives of about 1 in 100 patients, according to the Center for Disease Control and Prevention. Infected individuals will typically experience fever, chills, muscle aches, headaches and fatigue one to two weeks after being bitten. But if people aren't treated quickly, the infection can sometimes lead to brain and nervous system damage, respiratory failure, uncontrolled bleeding and organ failure. The number of Ehrlichiosis cases has risen steadily since 2000 when the CDC reported 200 cases of Ehrlichiosis compared with 2,093 in 2019. Studies suggest that the number of annual Ehrlichiosis cases are grossly underreported with one study from Rutgers University researchers saying 99% of cases go undetected. The CDC reported earlier this month that there have been more emergency room visits in July for tick bites than the past eight Julys. In early July, officials closed Pleasure Beach, a popular swim spot in Bridgeport, Connecticut, for the summer after discovering an infestation of several tick species including the longhorned tick. Manisha Juthani, the commissioner of the Connecticut Department of Public Health, said that as climate change makes 'tick season' less predictable, Connecticut residents should take precautions like wearing long pants, tucking them into their socks and conducting tick checks on family members and pets after being outdoors for extended periods of time. 'The reality is that with the changes we're seeing in climate, we have to be more prepared and more aware of the infections and the pathogens that we can be exposed to by being outside and potentially being aware of the things that can really cause the most harm to people,' Juthani said. While longhorned ticks often prefer the blood of livestock to humans, entomologists say their unique biology makes them a formidable public health hazard. They can establish populations of thousands from a single female because, like bees, they have the ability to reproduce without a mate. They can also ingest and become carriers for pathogens typically carried by other tick species if they happen to feed on the same host. The process, known as co-feeding transmission, is common among most tick species. Molaei said his recent discovery of the Ehrlichiosis-causing bacteria in the longhorned tick raises concerns about what other pathogens the tick may be able to contract and transmit to humans. The longhorned tick and the lone star tick, one of the original carriers of ehrlichia, both feed on similar hosts, like white-tailed deer. 'We live in this part of the world with several important tick species, and we have to learn how to live with this many ticks,' Molaei said. 'And the key is to protect ourselves.' The World Health Organization reports that more than 17% of infectious diseases globally are transmitted through vectors, intermediary animals that ferry viruses, bacteria and other pathogens from one animal to the next. Tick-borne diseases in the U.S. accounted for 77% of vector-borne disease reports from 2004 to 2016, with cases more than doubling in the last 13 years, according to data collected by the CDC. Jennifer Platt was bitten by a tick during that time. She contracted Ehrlichiosis from a tick bite in North Carolina in the summer of 2011. When she couldn't pick up and carry her 2-year-old son, her friend, who is a nurse, suggested she go to the hospital immediately. The friend suspected Platt might have a tick-borne infection. Platt was sick and on antibiotics for months after her diagnosis. Her shoulder locked due to the infection — a rare but contractable chronic symptom of tick-borne disease — leading to months of physical therapy and putting her out of work for three months. It took her more than a year to fully recover from the lasting impacts of the infection. 'The best way I'd describe it,' she said, 'is I felt like death.' A few years after she started feeling better, she was diagnosed with Lyme and Babesiosis diseases — which she attributes to the same tick bite. Platt, who co-founded the advocacy nonprofit Tick-Borne Conditions United, said she hopes the recent discovery of the Ehrlichia bacteria in the longhorned tick will help raise awareness among doctors and the general public about the threat of tick-borne diseases, especially little-known ones like Ehrlichiosis. 'My mission in life is to support people in being who they are,' Platt said. 'And if you're sick from a tick-borne disease, you can't be who you are.'

Why Is Martha's Vineyard Going Vegan? It's All About Tick Bites.
On Martha's Vineyard, this was supposed to be the summer of the shark. Instead, it's the time of the tick. The Massachusetts island is throwing a monthslong party for the 50th birthday of 'Jaws,' with tours of locations where the movie was filmed, a museum show, grinning-shark cashmere sweaters and a commemorative kale salad featuring turnips carved in the shape of sharks' teeth. As the season has gone on, though, great white sharks have been replaced as the Vineyard's scariest animal. When islanders get together these days, they talk about their fears of an eight-legged creature the size of a grape seed. On the porch of the Chilmark General Store and at sunset-watching parties on Menemsha Beach, conversations circle ineluctably to the lone star tick, which after a single bite can leave people with a life-threatening allergy to most meat and dairy. Known as alpha-gal syndrome, the condition is changing the way many people shop, cook and eat in a place long known as a food-lover's retreat for its thriving independent farms and restaurants. These new habits may prove to be lasting, as some islanders who initially avoided beef and cheese temporarily, out of necessity, later give them up for good out of preference. Want all of The Times?

Stay safe from insect and animal bites this summer: AHS
Albertans are encouraged to take precaution on outdoor summer adventures to prevent insect and animal bites and infections. To prevent mosquito and tick bites, Alberta Health Services (AHS) suggests covering as much of your body as possible when outdoors – especially in grassy or wooded areas where ticks are commonly found. The health authority recommends wearing a light-coloured, long-sleeved shirt, long pants and a hat as well as Health Canada-approved insect repellent. Mosquitoes can spread West Nile virus which can affect your brain and give you flu-like symptoms. Ticks can carry Lyme disease. AHS advises to always check for ticks when you come in from the outdoors. Bats have been known to carry rabies in Alberta, which can impact your nervous system, including the brain, spinal cord and nerves. AHS says to never handle a live or dead bat with bare hands as bats are likely to bite in self-defence. If you or your child are bitten or scratched by a bat, AHS says to wash with soap and water and call Health Link at 811 or speak to a health care provider. Household pets and indoor animals should be up-to-date on routine rabies immunizations. It is also recommended that parents speak with their children about not touching wild animals and to tell an adult when they've been bitten or scratched.
