Lyme disease is caused by a type of bacteria called Borrelia burgdorferi, which has several hybrid strains that lead to this illness. These microorganisms are transmitted to humans through ticks that belong to the Ixodes genus, like the deer tick. These ticks are normally uninfected; they only acquire the bacteria when they bite infected animals. Once they get infected, ticks move on to other hosts, including humans, and they transmit Borrelia burgdorferi when they bite their host and their saliva (containing the bacteria) enters the host’s body. Ticks must be attached to their hosts up to 48 hours for them to transmit the bacteria.
The Mortality Rate of Lyme Disease
Lyme disease, in itself, is usually not fatal. A study conducted by the United States’ Centers for Disease Control and Prevention showed that, between 1999 and 2003, only 114 death certificates listed the illness as a cause of death. Only 23 cases mentioned Lyme disease as the underlying cause of death; most …show more content…
Several weeks after they become infected with the Borrelia burgdorferi bacteria, patients can develop neurologic problems such as aseptic meningitis and inflammation of the motor and sensory nerves. The brain can also develop inflammation, leading to encephalitis. In rare cases, Lyme disease can lead to cardiovascular problems, such as atrioventricular block (which can lead to abnormally low heart rates), myopericarditis (inflammation of the tissues that surround the heart) and cardiomegaly (enlarged heart). These neurologic and cardiovascular issues can lead to death if they’re not properly
