Eight diseases you can get from kissing

1. Mononucleosis also called "Mono"
 

It is usually caused by the Epstein-Barr virus (EBV), spreads through saliva and is often referred to as “mono” or “the kissing disease.” Symptoms are very similar to those of the flu and include a fever, sore throat, fatigue, muscle weakness and swollen lymph glands.

The infection and related symptoms usually last anywhere from one to two months. Young people between the ages of 15 and 30 and those who regularly come into contact with a lot of people are the most at risk. While no treatment for mononucleosis exists, resting, staying hydrated and taking over-the-counter pain medications often help.

2. Cytomegalovirus

(CMV) is a virus in the herpes family. This disease spreads through saliva, as well as through blood, urine, semen and breast milk. Like all herpes viruses, CMV can remain dormant in the body for long periods of time, especially if you’re healthy.

Though this virus can infect almost anyone, symptoms usually appear in those with compromised immune systems. Symptoms can include fatigue, fever, muscle aches and, in more serious cases, pneumonia, encephalitis, seizures and visual impairment. While there’s no cure for CMV, treatment for the virus generally isn’t needed in healthy children and adults.

3.Gum Disease

Bacteria, mucus and other particles constantly live in our mouths and can build up to form plaque. Brushing and flossing helps get rid of plaque, though if not cleaned thoroughly, plaque can build up under the gum line and cause gum disease. Though gum disease (also known as periodontitis and gingivitis) does not spread through kissing, the bad bacteria that cause it can. Brushing and flossing your teeth regularly is your best defense.

4. Herpes

Oral herpes is most commonly referred to as “cold sores” or “fever blisters.” It’s transmitted through direct contact between an infected area and broken skin or a mucous membrane but symptoms aren’t always visible.

Unfortunately, once you contract the virus, it stays with you forever. Additionally, oral herpes, caused by the herpes simplex type 1 strain, can cause genital herpes. Experts estimate that over 20 percent of new genital herpes cases are caused by herpes simplex type 1 transmitted through oral sex.

Outbreaks of oral herpes, however, are usually few and far between. During an outbreak, symptoms usually last between 8-10 days on average and the cold sores heal on their own.

5. Meningitis

Many types of viruses can cause viral meningitis which is serious but less severe than bacterial meningitis. This disease can be spread from one person to another via respiratory secretions.

Symptoms include fever, headache, stiff neck, nausea and vomiting. Though there are no medications for viral meningitis, people with healthy immune systems usually get better on their own.

6. Mumps

Mumps is a viral infection that affects the salivary glands, causing them to swell. It usually spreads via airborne droplets from the nose or throat of an infected person. Easily preventable by vaccine, this disease is no longer as common as it once was, though outbreaks in unvaccinated groups still sporadically occur.

Symptoms typically include fever, headache, muscle aches, fatigue and loss of appetite. Recovering from mumps takes about two weeks, and treatment usually focuses on relieving the symptoms.

7. Rubella

Also known as the German measles, it is a contagious disease caused by a virus transmitted through an infected person's sneeze or cough.

Symptoms only show up in half of people who get rubella and are usually mild. They include a fever and rash and clear up in two to three days. The rubella vaccine can prevent this disease.

8. Influenza

Influenza is spread from person to person, usually via droplets made when people with the flu cough, sneeze or talk. People can infect others with the flu virus one day before they have symptoms and up seven days after becoming sick.

Symptoms include fever, cough, sore throat, body aches and fatigue. Most people recover on their own in less than two weeks. The flu is a highly seasonal disease that can often be prevented by getting an annual flu vaccine.
