Infectious: Infectious mononucleosis is caused by the epstein barr virus (ebv) and acute infection usually involves sore throat, fever, enlarged lymph nodes (including the spleen), and tiredness. Different people will have a different severity of mono symptoms - some get very ill, some do not get sick at all. It is spread through saliva and close contact which is why it's been known as the "kissing disease". Since it is a virus, it is not treated with antibiotics. There is a blood test available that can test for mono infection and antibodies. The test will tell you if he has ever had it, if he has it now, or if he had it in the past and is now immune to it - all helpful information. A strep test does not give information about any other infections - just strep.

I attached a link for more in-depth information on infectious mono below. ...Read more

If you don't have a fever does that mean it's not strep throat?

Not necessarily: Although fever is common with strep throat, it is not proof that you don't have it. If the sore throat is fairly painful, and especially if you don't feel well otherwise--headache, aches and pains etc.--it is still possible. Strep doesn't usually come with a lot of cold symptoms like runny nose and congested cough. Only way to be sure is to get checked, possibly with a test for strep. ...Read more

But, not all sore throats are due to strep throat. Your primary care doctor will be able to determine this by taking a throat culture. Often, sore throats are caused by viruses, which are self-limited. ...Read more
