Around 50 percent of people with Lyme disease experience flu-like symptoms within a week of being infected.
The symptoms may be low-level and often a person does not think Lyme disease is the cause for these headaches.
In fact, distinguishing Lyme disease symptoms can often be mistaken for having a flu or a viral infection.
But around 78 percent of children reported first experiencing headaches and 48 percent of adults revealed headaches as the first warning sign.
Unlike suffering from a flu or viral infection, symptoms of Lyme disease come and go.
