What is Infection?

The virus was first discovered in 1964 when Sir Michael Anthony Epstein and Yvonne Mr. Barr found it in a Burkitt lymphoma cell line. In 1968, the virus was linked to the disease infectious mononucleosis. Infection with Epstein-Barr virus (EBV) is very common and usually occurs in childhood or early adulthood. In fact, up to 95% of people in the U.S. have been infected with EBV. EBV is the cause of infectious mononucleosis (also termed "mono"), an illness associated with fever, sore throat, swollen lymph nodes in the neck, and sometimes an enlarged spleen. Less commonly, EBV can cause more serious disease. Symptoms caused by EBV are usually mild and self-limited, but the virus persists in the body for life. It can reactivate quietly without causing symptoms and may contaminate saliva. Thus, otherwise healthy people can spread the virus to uninfected people through kissing or sharing food. Hence, mononucleosis is sometimes known as the "kissing disease." EBV probably plays a role in the development of some cancers including certain lymphomas and nasopharyngeal cancer.

Ear Infections

Inflammation of the ear, differentiated as outer ear (Otitis Externa), middle ear (Otitis Media), and inner ear (Otitis Interna). About 95% of all children have had ear infections by the age of six. If persistent, ear infections may lead to eardrum damage and eventual loss of hearing. Pressure on sensitive nerves causes pain. See your doctor for diagnosis and treatment.

Cytomegalovirus Infections
Cytomegalovirus (CMV) is a virus found around the world. It is related to the viruses that cause chickenpox and infectious mononucleosis (mono). Between 50 percent and 80 percent of adults in the United States have had a CMV infection by age 40. Once CMV is in a person's body, it stays there for life. Most people with CMV don't get sick. But infection with the virus can be very serious in babies and people with weak immune systems. If a woman gets CMV when she is pregnant, she can pass it on to her baby. CMV does not harm most babies. But some develop lifelong disabilities.

EBV Infections
Infectious mononucleosis, or "mono", is an infection caused by the Epstein-Barr virus. The virus spreads through saliva, which is why it's sometimes called "kissing disease." Mono occurs most often in 15 to 17-year-olds. However, you can get it at any age. Symptoms of mono include Sometimes you may also have a swollen spleen. Serious problems are rare.

HIV infection
HIV infection is a disease caused by the human immunodeficiency virus (HIV). The condition gradually destroys the immune system, which makes it harder for the body to fight infections. This article provides a general overview. For more detailed information, see: AIDS Acute HIV infection Asymptomatic HIV infection Early symptomatic HIV infection

Respiratory Syncytial Virus Infections
Respiratory syncytial virus (RSV) causes mild, cold-like symptoms in adults and older children. However, it can cause serious problems in young babies, including pneumonia and severe breathing problems. In rare cases it can lead to death. Premature babies and those with other health problems have the highest risk. A child with RSV may have a fever, stuffy nose, cough and trouble breathing. Tests can tell if your child has the virus. RSV easily spreads from person to person. You can get it from direct contact with someone who has it or it by touching infected objects such as toys or surfaces such as countertops. Washing your hands often and not sharing eating and drinking utensils are simple ways to help prevent the spread of RSV infection. There is currently no vaccine for RSV.

HPV infection
HPV infection is a condition contracted from one of a group of more than 100 related human papillomaviruses (HPVs).

Eye Infections
Your eyes can get infections from bacteria, fungi or viruses. Eye infections can occur in different parts of the eye and can affect just one eye or both. Two common eye infections are Symptoms of eye infections may include redness, itching, swelling, discharge, pain, or problems with vision.

Ear infection - acute
Ear infections are one of the most common reasons parents take their children to the doctor. While there are different types of ear infections, the most common is called otitis media, which means an inflammation and infection of the middle ear. The middle ear is located just behind the eardrum. The term "acute" refers to a short and painful episode. An ear infection that lasts a long time or comes and goes is called chronic otitis media. For links to other types of ear infections, see otitis.

Ear infection, middle ear
Middle ear infections, also known as otitis media, are among the most common illnesses of early childhood. Three out of four children have had at least one ear infection by age 3, according to the National Institute on Deafness and Other Communication Disorders.

Ear Infections
Ear infections are the most common illnesses in babies and young children. Most often, the infection affects the middle ear and is called otitis media. The tubes inside the ears become clogged with fluid and mucus. This can affect hearing, because sound cannot get through all that fluid. If your child does not yet talk, you need to look for signs of an infection:

Ear infection - chronic
Chronic ear infection is inflammation or infection of the middle ear that persists or keeps coming back, and causes long-term or permanent damage to the ear. See also: Acute ear infection

Infection, Ear
Infection can affect the ear canal (otitis externa), the eardrum, or the middle ear (otitis media). Most ear injuries are caused by pressure changes during direct injury (such as a blow to the ear) or sport scuba diving, but, a persistently painful ear may signal an infection that requires treatment. Because an ear scope (otoscope) may not be available to examine the canal and inner ear in remote locations, starting therapy may be appropriate until a doctor can be reached.
