B25-B34 Other Viral Diseases

Other viral diseases B25-B34 >


Cytomegaloviral disease B25-

Clinical Information

A herpesvirus infection caused by cytomegalovirus.

Healthy individuals generally do not produce symptoms.

However, the infection may be life-threatening in affected

immunocompromised patients. The virus may cause retinitis,

esophagitis, gastritis, and colitis. Morphologically, it

is characterized by the presence of intranuclear inclusion


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.

cmv is spread through close contact with body fluids. You should

use good hygiene, including proper hand washing, to avoid catching

or spreading the virus. Most people with cmv don't require treatment.

If you have a weakened immune system, your doctor may prescribe

antiviral medicine. Centers for Disease Control and Prevention.

Infection with cytomegalovirus, characterized by enlarged cells

bearing intranuclear inclusions. Infection may be in almost any

organ, but the salivary glands are the most common site in children,

as are the lungs in adults.


Mumps B26- >



epidemic parotitis

infectious parotitis

Clinical Information

A contagious viral infection caused by the mumps virus. Symptoms

include swollen and tender parotid glands, fever, muscle aches and

fatigue. Due to vaccination programs, mumps has become a rare disease.

Acute, inflammatory, contagious disease caused by rubulavirus and

characterized by swelling of the salivary glands, especially the

parotids, and sometimes of the pancreas, ovaries, or testes;

spread by direct contact, airborne droplet nuclei, fomites

contaminated by infectious saliva, and perhaps urine.

An acute infectious disease caused by rubulavirus, spread by

direct contact, airborne droplet nuclei, fomites contaminated

by infectious saliva, and perhaps urine, and usually seen in children

under the age of 15, although adults may also be affected.

Mumps is an illness caused by the mumps virus. It starts with



muscle aches


loss of appetite

after that, the salivary glands under the ears or jaw become

swollen and tender. The swelling can be on one or both sides

of the face. Symptoms last 7 to 10 days. Serious complications

are rare.you can catch mumps by being with another person who

has it. There is no treatment for mumps, but the measles-mumps-rubella

(mmr) vaccine can prevent it.before the routine vaccination program

in the United States, mumps was a common illness in infants, children

and young adults. Now it is a rare disease in the United States


Infectious mononucleosis B27- >



glandular fever

monocytic angina

Pfeiffer's disease

Clinical Information

A common, acute infection usually caused by the epstein-barr virus

(herpesvirus 4, human). There is an increase in mononuclear white

blood cells and other atypical lymphocytes, generalized lymphadenopathy,

splenomegaly, and occasionally hepatomegaly with hepatitis.

Acute disease characterized by fever and swollen lymph nodes and an

abnormal increase of mononuclear leucocytes or monocytes in the

bloodstream; not highly contagious; some believe it can be

transmitted by kissing.

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


sore throat

swollen lymph glands

sometimes you may also have a swollen spleen. Serious problems

are rare. A blood test can show if you have mono. Most people get

better in two to four weeks. However, you may feel tired for a

few months afterward. Treatment focuses on helping symptoms

and includes medicines for pain and fever, warm salt water

gargles and plenty of rest and fluids.


Viral conjunctivitis B30- >

Clinical Information

Inflammation, often mild, of the conjunctiva caused by a variety

of viral agents. Conjunctival involvement may be part of a systemic



Viral infection of unspecified site B34- >


Type 1 Excludes

anogenital human papillomavirus infection (A63.0)

cytomegaloviral disease NOS (B25.9)

herpesvirus [herpes simplex] infection NOS (B00.9)

retrovirus infection NOS (B33.3)

viral agents as the cause of diseases classified elsewhere (B97.-)

viral warts due to human papillomavirus infection (B07)

Clinical Information

A general term for diseases produced by viruses.

Any disease caused by a virus.

Disease produced by viruses.

Viruses are capsules with genetic material inside. They are very

tiny, much smaller than bacteria. Viruses cause familiar infectious

diseases such as the common cold, flu and warts. They also cause

severe illnesses such as hiv/aids, smallpox and hemorrhagic fevers.

viruses are like hijackers. They invade living, normal cells and use

those cells to multiply and produce other viruses like themselves.

This eventually kills the cells, which can make you sick.viral

infections are hard to treat because viruses live inside your body's

cells. They are "protected" from medicines, which usually move

through your bloodstream. Antibiotics do not work for viral

infections. There are a few antiviral medicines available. Vaccines

can help prevent you from getting many viral diseases.
