Lyme disease is primarily transmitted through which of the following?

Lyme disease is primarily transmitted through tick bites because the bacterium that causes the disease, Borrelia burgdorferi, is carried by certain species of ticks, most commonly the black-legged tick (also known as the deer tick). When an infected tick bites a human or animal, it can transfer the bacteria into the bloodstream, leading to Lyme disease.

Ticks typically attach themselves to the host and feed on their blood, and it usually takes several hours for the bacteria to be transmitted after the tick has attached. This transmission mechanism highlights the importance of tick prevention strategies in areas where Lyme disease is prevalent, such as wearing protective clothing when outdoors, using tick repellents, and performing regular tick checks after being in wooded or grassy areas.

Mosquitoes, dog bites, and flea bites do not play a role in the transmission of Lyme disease. Mosquitoes are known to transmit different types of diseases, but not Lyme, while dog bites and flea bites do not carry the bacterium that causes Lyme disease, making them irrelevant to this specific question. Understanding the correct vector for Lyme disease is crucial for prevention and awareness.
