The mumps virus (MuV) is the virus that causes mumps. MuV contains a single-stranded, negative-sense genome made of ribonucleic acid (RNA). Its genome is about 15,000 nucleotides in length and contains seven genes that encode nine proteins. The genome is encased by a capsid that is in turn surrounded by a viral envelope.
An asymptomatic carrier is a person or other organism that has become infected with a pathogen, but shows no signs or symptoms. [1] Although unaffected by the pathogen, carriers can transmit it to others or develop symptoms in later stages of the disease. Asymptomatic carriers play a critical role in the transmission of common infectious ...
Congenital rubella syndrome. Congenital rubella syndrome (CRS) occurs when an unborn baby is infected with the rubella virus (German measles) via maternal-fetal transmission and develops birth defects. [1] The most common congenital defects affect the ophthalmologic, cardiac, auditory, and neurologic systems. [2]

[10] The most common symptoms are fever, intense headache, vomiting and neck stiffness and occasionally photophobia. [1]
Acute viral parotitis (mumps): The most common viral cause of parotitis is mumps. Routine vaccinations have dropped the incidence of mumps to a very low level. Mumps resolves on its own in about ten days. A viral infection caused by Paramyxovirus, a single-stranded RNA virus. Common symptoms include fever, headache and bilateral or unilateral ...
The anatomical structure of the human brain. Aseptic meningitis is the inflammation of the meninges, a membrane covering the brain and spinal cord, in patients whose cerebral spinal fluid test result is negative with routine bacterial cultures. Aseptic meningitis is caused by viruses, mycobacteria, spirochetes, fungi, medications, and cancer ...
Sialadenitis ( sialoadenitis) is inflammation of salivary glands, usually the major ones, the most common being the parotid gland, followed by submandibular and sublingual glands. [1] It should not be confused with sialadenosis (sialosis) which is a non-inflammatory enlargement of the major salivary glands. [2]
Viral meningitis causes inflammation of the meninges. Viral meningitis, also known as aseptic meningitis, is a type of meningitis due to a viral infection. It results in inflammation of the meninges (the membranes covering the brain and spinal cord ). Symptoms commonly include headache, fever, sensitivity to light and neck stiffness.
