About 300,000 cases of tick-borne Lyme disease are diagnosed in the U.S. each year, and with an expanding tick population, experts think this year could be worse than usual.
每年，美国约有三十万例蜱传播的莱姆病，随着蜱数量的增长，今年可能会比平时更糟。
Thanks to a milder winter and more host animals, there could be more cases of Lyme and deadly tick-borne infections.
由于温和的冬天和更多的宿主动物，可能有更多莱姆病例和致命蜱感染。
Powassan virus, for example, causes swelling in the brain that can lead to permanent neurological damage. It's fatal in about 10 percent of cases.
例如玻瓦桑病毒，使大脑肿胀并导致永久性的神经损伤。大约10%的病例是致命的。
Some ticks even carry another disease that can give you a meat allergy. Researchers warn it's getting more common, but they're still learning about how and why the disease spreads. The Centers for Disease Control and Prevention isn't tracking it closely yet.
一些蜱甚至携带另一种疾病，可以使你肉过敏。研究人员警告称，现在这种情况越来越普遍，但他们仍在学习这种疾病如何和为何蔓延。美国疾病控制与预防中心也没有密切跟踪。
Luckily, those diseases are still relatively rare, especially compared with Lyme. For example, in the decade since 2006, the CDC recorded fewer than seven cases of Powassan virus on average every year.
幸运的是，这些疾病仍然是比较少见的，尤其是相比于莱姆病。例如，自2006年以来的十年，美国疾病控制与预防中心记录的玻瓦桑病毒平均每年少于7例。
The CDC recommends people avoid tick-borne diseases by using insect repellent, staying out of brush and tall grass, and taking showers after visits to tick country. If you're bitten, tell your doctor about any fever or rash.
疾病控制与预防中心建议人们使用驱虫剂避免蜱传播疾病，远离灌木丛和高草从，访问有蜱的农村后洗澡。如果你被咬了，有任何发热或皮疹，告诉你的医生。
