During the nymph stage, ticks most frequently transmit Lyme disease and are usually most active in late spring and early summer in regions where the climate is mild. During the adult stage, Lyme disease transmission is less common because adult ticks are less likely to bite humans and tend to be larger in size, so can be easily seen and removed ...
Overall climate is more determinate of tick population and daily weather has a subtle effect on the spread of tick-borne disease. Being mindful of daily weather patterns and vigilantly avoiding exposure to ticks reduces human exposure to Lyme disease.

Borrelia in the manifestation of Lyme disease in this region is presently unknown, but evidence indicates the disease may occur in humans in sub-Saharan Africa. The abundance of hosts and tick vectors would favor the establishment of the infection in Africa. [34] In East Africa two cases of Lyme disease have been reported in Kenya. [35]
For example, the bacterium Borrelia burgdorferi, the causative agent for Lyme disease, infects the tick vector as a larva, with the infection maintained as the tick molts to a nymph and later develops as an adult. [1] [2] Transstadial transmission is also seen with other microbes such as other bacteria, fungi, and viruses in numerous insects. [3]
B. burgdorferi is the causative agent of Lyme disease and is why this bacteria is so important and being studied. It is most commonly transmitted from ticks to humans. Humans act as the tick's host for this bacteria. Lyme disease is a zoonotic, vector-borne disease transmitted by the Ixodes tick (also the vector for Babesia and Anaplasma).
According to the Centers for Disease Control and Prevention, humans get infected after being bitten by blacklegged ticks (or deer ticks). Lyme disease can happen to any age group, but those at ...
Ticks and lice form another large group of invertebrate vectors. The bacterium Borrelia burgdorferi, which causes Lyme Disease, is transmitted by ticks and members of the bacterial genus Rickettsia are transmitted by lice. For example, the human body louse transmits the bacterium Rickettsia prowazekii which causes epidemic typhus.
Transmission of the bacterium that causes Lyme disease is well understood to require a substantial feeding period. [25] In general, soft ticks ( Argasidae ) transmit pathogens within minutes of attachment because they feed more frequently, whereas hard ticks ( Ixodidae ) take hours or days, but the latter are more common and harder to remove.
