18. Lyme disease
In the United States, Lyme disease is the most frequent vector-borne disease. Borrelia burgdorferi and, in rare cases, Borrelia mayonii cause Lyme disease. It is spread to humans via the biting of infected blacklegged ticks. Typical symptoms include fever, headache, tiredness, and an erythema migrans-like skin rash. Infection can spread to joints, the heart, and the neurological system if left untreated. Lyme disease is diagnosed based on symptoms, physical findings (such as a rash), and the probability of tick-borne infection. Laboratory testing is beneficial when used correctly and using approved methodologies. Most Lyme disease patients can be successfully treated with a few weeks of medication. Using insect repellent, removing ticks promptly, and using insecticides are all ways to avoid Lyme disease. Lyme disease is caused by four different types of bacteria. Borrelia burgdorferi and Borrelia mayonii are the most common pathogens in the United States, whereas Borrelia afzelii and Borrelia garinii are the most common in Europe and Asia. Lyme disease, the most common tick-borne infection in these areas, is spread by the bite of an infected black-legged tick, sometimes known as a deer tick. If you live or spend time in grassy or heavily wooded areas where ticks carrying Lyme disease thrive, you are more likely to contract the condition. In tick-infested locations, common sense precautions must be taken. Lyme disease symptoms and indicators vary. They often manifest in stages, however the stages may overlap. A little, red bump, similar to a mosquito bite, frequently forms at the site of a tick bite or tick removal and fades within a few days. This is a common occurrence and does not suggest Lyme illness. However, the following signs and symptoms might appear within a month of infection: A Rash. A growing red patch may occur three to 30 days following an infected tick bite, occasionally clearing in the center, forming a bull’s-eye pattern. The rash (erythema migrans) spreads slowly over days and can reach a diameter of 12 inches (30 centimeters). It is not usually itchy or painful, but it may feel warm to the touch. Erythema migrans is one of the symptoms of Lyme disease, albeit it does not appear in every case. Some people have this rash in more than one location on their body. The rash may be accompanied by fever, chills, weariness, body aches, headache, neck stiffness, and swollen lymph nodes. Only a small percentage of tick bites cause Lyme illness. The longer the tick is attached to your skin, the more likely you are to contract the disease. If the tick is attached for less than 36 to 48 hours, Lyme disease is unlikely. Contact your doctor if you believe you’ve been bitten and have signs and symptoms of Lyme disease, especially if you live in an area where Lyme disease is common. Early treatment for Lyme illness is more effective than if one waits for symptoms to exacerbate.
