At a time of year when people are coming down with viruses of all kinds, it can be hard to tell if it's a run-of-the-mill flu, or something more serious, like mononucleosis.
Mono, known as the "kissing disease" or more technically as the Epstein-Barr virus, is often associated with teenagers, but people of any age (including little kids) can get it. It is most common in people aged 15 to 30, because as a member of the herpes virus family, many older people have build an immunity to it, according to Healthline.
While the virus itself is not dissimilar to the flu, it does have longer lasting effects, often taking people out of commission for one to two months. According to WebMD, symptoms start to show four to six weeks after being exposed to the virus, which is passed via direct transmission of saliva — which can mean anything from sharing drinks and lip balm to kissing.
But how can you tell if what you have is a cold or flu, or mono? The first clue is you're not getting better after one or two weeks of rest, and it's at this point you need to see your doctor, recommends Healthline. Take a look at the other symptoms of mono, and what you can do to get yourself better, in the slideshow below:
