References to measles can be found from as early as the 7th century. The disease was described by the Persian physician Rhazes in the 1. Enders and Peebles isolated the virus in human and monkey kidney tissue culture in 1. The first live attenuated vaccine was licensed for use in the United States in 1.

Measles is still a common and often fatal disease in developing countries. The World Health Organization estimates there were 1. Top of Page. Measles Virus. Measles Virus. Paramyxovirus (RNA)Hemagglutinin important surface antigen.

Two membrane envelope proteins are important in pathogenesis. They are the F (fusion) protein, which is responsible for fusion of virus and host cell membranes, viral penetration, and hemolysis, and the H (hemagglutinin) protein, which is responsible for adsorption of virus to cells. There is only one antigenic type of measles virus.
Although studies have documented changes in the H glycoprotein, these changes do not appear to be epidemiologically important (i. Measles virus is rapidly inactivated by heat, sunlight, acidic p.

Primary viremia 2- 3 days after exposure. Secondary viremia 5- 7 days after exposure with spread to tissues.
Measles is a systemic infection. The primary site of infection is the respiratory epithelium of the nasopharynx.
Two to three days after invasion and replication in the respiratory epithelium and regional lymph nodes, a primary viremia occurs with subsequent infection of the reticuloendothelial system. Following further viral replication in regional and distal reticuloendothelial sites, a second viremia occurs 5. During this viremia, there may be infection of the respiratory tract and other organs.
Measles virus is shed from the nasopharynx beginning with the prodrome until 3. From exposure to rash onset averages 1. It is characterized by fever, which increases in stepwise fashion, often peaking as high as 1. This is followed by the onset of cough, coryza (runny nose), or conjunctivitis. Koplik spots, a rash present on mucous membranes, is considered to be pathognomonic for measles. It begins at the hairline, then involves the face and upper neck. During the next 3 days, the rash gradually proceeds downward and outward, reaching the hands and feet.
The maculopapular lesions are generally discrete, but may become confluent, particularly on the upper body. Initially, lesions blanch with fingertip pressure. Fine desquamation occurs over more severely involved areas. The rash fades in the same order that it appears, from head to extremities.
Other symptoms of measles include anorexia; diarrhea, especially in infants; and generalized lymphadenopathy. Top of Page. Complications.

From 1. 98. 5 through 1. Otitis media was reported in 7% of cases and occurs almost exclusively in children. Pneumonia (in 6% of reported cases) may be viral or superimposed bacterial, and is the most common cause of measles- related death. Acute encephalitis occurs in approximately 0.
Onset generally occurs 6 days after rash onset (range 1. Cerebrospinal fluid shows pleocytosis and elevated protein. The case- fatality rate is approximately 1. Some form of residual neurologic damage occurs in as many as 2. Seizures (with or without fever) are reported in 0. As with other complications of measles, the risk of death is highest among young children and adults.
Pneumonia accounts for about 6. The most common causes of death are pneumonia in children and acute encephalitis in adults. Subacute sclerosing panencephalitis (SSPE) is a rare degenerative central nervous system disease believed to be due to persistent measles virus infection of the brain. Onset occurs an average of 7 years after measles (range 1 month. The onset is insidious, with progressive deterioration of behavior and intellect, followed by ataxia (awkwardness), myoclonic seizures, and eventually death. SSPE has been extremely rare since the early 1.
Measles illness during pregnancy results in a higher risk of premature labor, spontaneous abortion, and low- birthweight infants. Birth defects (with no definable pattern of malformation) have been reported rarely, without confirmation that measles was the cause.
An estimated 6. 00,0. KMV in the United States from 1. KMV sensitizes the recipient to measles virus antigens without providing protection. Subsequent infection with measles virus leads to signs of hypersensitivity polyserositis. The illness is characterized by fever, pneumonia, pleural effusions, and edema. The rash is usually maculopapular or petechial, but may have urticarial, purpuric, or vesicular components. It appears first on the wrists or ankles.
Atypical measles may be prevented by revaccinating with live measles vaccine. Moderate to severe local reactions with or without fever may follow vaccination; these reactions are less severe than with with wild measles virus infection. Modified measles occurs primarily in patients who received immune globulin (IG) as postexposure prophylaxis and in young infants who have some residual maternal antibody. It is usually characterized by a prolonged incubation period, mild prodrome, and sparse, discrete rash of short duration. Similar mild illness has been reported among previously vaccinated persons. Rarely reported in the United States, hemorrhagic measles is characterized by high fever (1. It is reported almost exclusively in persons with T- cell deficiencies (certain leukemias, lymphomas, and acquired immunodeficiency syndrome .
It may occur without the typical rash, and a patient may shed virus for several weeks after the acute illness. Measles in developing countries has resulted in high attack rates among children younger than 1.
Measles is more severe in malnourished children, particularly those with vitamin A deficiency. Complications include diarrhea, dehydration, stomatitis, inability to feed, and bacterial infections (skin and elsewhere).
The case- fatality rate may be as high as 2. Measles is also a leading cause of blindness in African children. Top of Page. Laboratory Diagnosis. Measles Laboratory Diagnosis. Isolation of measles virus from urine, nasopharynx, blood, throat. Significant rise in measles Ig.

M antibody. Isolation of measles virus is not recommended as a routine method to diagnose measles. However, virus isolates are extremely important for molecular epidemiologic surveillance to help determine the geographic origin of the virus and the viral strains circulating in the United States. Measles virus can be isolated from urine, nasopharyngeal aspirates, heparinized blood, or throat swabs.
Specimens for virus culture should be obtained from every person with a clinically suspected case of measles and should be shipped to the state public health laboratory or CDC, at the direction of the state health department. Clinical specimens for viral isolation should be collected at the same time as samples taken for serologic testing. Because the virus is more likely to be isolated when specimens are collected within 3 days of rash onset, collection of specimens for virus isolation should not be delayed until serologic confirmation is obtained. Clinical specimens should be obtained within 7 days, and not more than 1. A detailed protocol for collection of specimens for viral isolation is available on the CDC website. Serologic testing, most commonly by enzyme- linked immunoassay (EIA), is widely available and may be diagnostic if done at the appropriate time.
Generally, a previously susceptible person exposed to either vaccine or wild- type measles virus will first mount an Ig. M response and then an Ig. G response. The Ig.
M response will be transient (1. Uninfected persons should be Ig. M negative and will be either Ig. G negative or Ig.
G positive, depending upon their previous infection or vaccination history. EIA for Ig. M antibody requires only a single serum specimen and is diagnostic if positive. The preferred reference test is a capture Ig. M test developed by CDC.
This test should be used to confirm every case of measles that is reported to have some other type of laboratory confirmation. Ig. M capture tests for measles are often positive on the day of rash onset. However, in the first 7. Ig. M may give false- negative results. Tests that are negative in the first 7. Ig. M is detectable for at least 3.
A variety of tests for Ig. G antibodies to measles are available and include EIA, hemagglutination inhibition (HI), indirect fluorescent antibody tests, microneutralization, and plaque reduction neutralization. Complement fixation, while widely used in the past, is no longer recommended. Ig. G testing for acute measles requires demonstration of a four- fold rise in titer of antibody against measles virus, so two serum specimens are always required. The first specimen should be drawn as soon after rash onset as possible. The second specimen should be drawn 1.
The tests for Ig. G antibody should be conducted on both specimens at the same time. The same type of test should be used on both specimens.
The specific criteria for documenting an increase in titer depend on the test.
