    Spring is here and temperatures are heating up. That means cases of tick-borne (蜱传播的) illnesses, particularly Lyme disease, are on the rise. And the problem is only being worsened by drawn-out warmer weather across a wider area of the country.  (drive) by climate change. The warming climate enables ticks to become active  (early) in the spring and then remain active later into the autumn or winter months. 

    Blacklegged ticks  (be) not insects and they can carry more than a dozen rare  (disease). But the most common by far is Lyme disease. Typical signs of the illness include fever, headache, tiredness, muscle and joint pain and red spots on skin. 

    Ticks draw blood from an animal host that can contain        B.burgdorferi (伯氏疏螺旋体). An infected tick attaches to a human by digging its mouth into the flesh  it can feast for three to ten days.  takes at least 24 hours before Lyme bacteria start swimming out in the saliva the tick drips into its host. 

    Melissa Prustinsk, a research scientist at the New York State Department of Health, (warn) that it could be difficult to detect Lyme disease signs. "People often mistake them the flu or even COVID-19," she said. If you start to experience Lyme disease signs, don't wait around to spot the tick before (contact) a physician. "It's better to be safe than sorry, (especial) if you have spent time outdoors and know that there's the potential that you could have received the tick bites,"she advised.
