Ticks can carry more than one disease at a time, so it’s possible to contract multiple infections from just one bite.
Like Lyme, many tick-borne infections have flu-like symptoms – such as fever and headache – which makes diagnosis difficult.
Lyme treatment is complicated by co-infections. Patients with co-infections often don’t respond well to the usual treatments, and it takes an experienced doctor to properly identify and treat each tick-borne infection. Co-infection generally results in more severe illness, more symptoms, and a longer recovery.
