Measles: A Highly Contagious and Serious Airborne Disease

Measles is a highly contagious, serious airborne disease caused by a virus that can lead to severe complications and death [1]. It is a vaccine-preventable infectious disease that was once quite common among children but has now been largely prevented with the widespread use of the MMR (measles, mumps, and rubella) vaccine [2].

Characteristics of Measles

Measles is characterized by:

• Highly contagious: The virus spreads easily through breathing, coughing, and sneezing, making it a highly infectious disease [3].
• Viral infection: Measles is caused by a virus that lives in the nose and throat phlegm of an infected person [4].
• Acute illness: Measles is an acute viral disease capable of causing epidemics, with infectivity close to 100% in susceptible individuals [5].
• Symptoms: The symptoms of measles include fever, cough, coryza (runny nose), conjunctivitis (pink eye), and a distinctive red rash that appears as the illness progresses [6].

Complications and Prevention

Measles can lead to severe complications, including pneumonia, encephalitis, and even death. However, with two doses of the MMR vaccine, individuals can provide themselves with the best protection against this disease [7]. It is essential for children to receive the recommended number of MMR vaccinations to prevent measles and its potential complications.

Measles Signs and Symptoms

Measles, also known as rubeola, is a highly contagious viral infection that can cause a range of symptoms in affected individuals. The signs and symptoms of measles typically appear 7 to 14 days after contact with the virus.

Common Measles Symptoms:

• High Fever: A high fever is one of the first symptoms of measles, which may spike to more than 104°F (40°C) [1][2].
• Cough: A cough is another common symptom of measles, often accompanied by a runny nose and red, watery eyes [3][4].
• Runny Nose (Coryza): Measles typically begins with a runny nose, which can be followed by a sore throat and inflamed eyes [5][6].
• Red, Watery Eyes (Conjunctivitis): Red, watery eyes are another common symptom of measles, often accompanied by a cough and runny nose [7][8].
• Rash: A characteristic rash is one of the most distinctive symptoms of measles, which typically appears 2-4 days after the prodromal symptoms [9][10].

Other Measles Symptoms:

• Tiredness: Many people with measles experience tiredness or lethargy as a symptom [11].
• Sore Throat: A sore throat can also be a symptom of measles, often accompanied by a cough and runny nose [12].
• White Spots Inside the Mouth: Some people may develop white spots inside their mouth as a symptom of measles [13].

Complications:

Measles can cause serious health complications, especially in children younger than 5 years of age. These complications can include pneumonia, ear infections, and encephalitis (inflammation of the brain) [14][15].

Measles Diagnostic Tests

Measles can be diagnosed through various tests, which help confirm the presence of the virus in a patient. Here are some diagnostic tests used to detect measles:

• PCR (Polymerase Chain Reaction) Test: This is the preferred method for confirming an acute case of measles [4]. The test detects the genetic material of the measles virus and can provide quick results.
• IgM Antibody Test: This blood test measures the presence of IgM antibodies, which are produced in response to a recent infection. A positive result indicates that the patient has been infected with measles within the past few days [2].
• Serologic Testing: Blood tests can also detect the presence of measles-specific antibodies (IgG and IgM) in the blood. This test is useful for confirming immunity or diagnosing measles in patients who have not received a vaccination [7].
• Throat Swab Test: A throat swab can be used to collect a specimen for PCR testing, which can confirm the presence of the measles virus [2].

Other Tests

In addition to these tests, healthcare providers may also use other methods to diagnose measles, such as:

• Physical Examination: A healthcare provider will typically perform a physical examination and take a medical history to assess symptoms consistent with measles.
• Rash Observation: The characteristic rash of measles can often be observed by a healthcare provider, which can help confirm the diagnosis.

[1] CDC recommends that either a nasopharyngeal swab, throat swab, or urine specimen as well as a blood specimen be collected from all patients with symptoms consistent with measles. [2] If necessary, a blood test can confirm whether the rash is measles. The measles virus can also be confirmed with a test that generally uses a throat swab or nasopharyngeal swab. [3] Serum specimens for measles serologic testing (IgG, IgM) are delivered by courier to the STATT laboratory at CDC. [4] Only patients with symptoms consistent with measles will be considered for PCR or IgM testing. § RT-PCR is the preferred method for confirming an acute case. [5] Measles testing and mumps testing can help you find out if you have an active infection. The tests may help prevent the spread of disease. [6] A healthcare provider will usually be able to diagnose measles with a good history and physical exam and looking at the rash. However, they may order laboratory tests to confirm the diagnosis. [7] Serologic testing: • Blood should be collected as soon as possible after rash onset. [8] Serum for measles IgM: Measles IgM can be done in addition to PCR but should not be the only method used as false positives are common.

Medications Used to Treat Measles

Measles, a highly contagious viral infection, can be treated with various medications to alleviate symptoms and prevent complications. Here are some of the key drugs used in its treatment:

• Vitamin A: Vitamin A is recommended for people with measles, especially children, as it helps reduce the severity of the disease and prevents complications such as pneumonia and diarrhea [2].
• Antivirals (e.g., ribavirin): Antiviral medications like ribavirin can be used to treat measles in certain cases, such as in individuals with weakened immune systems or those who are at high risk of developing complications [3].
• Measles virus vaccine: While not a treatment for existing measles infection, the measles virus vaccine is an essential preventive measure against the disease.
• Immune globulin intramuscular systemic (GamaSTAN S/D): This medication is used to treat measles in individuals who are at high risk of developing complications or have weakened immune systems [7].

Symptom Relief

In addition to these medications, symptom relief measures such as:

• Fever-reducing NSAIDs: Medications like acetaminophen (Tylenol) and ibuprofen can help manage fever, aches, and pains associated with measles [5].
• Rest: Encouraging rest is essential in helping the body recover from the infection.
• Plenty of fluids: Drinking plenty of fluids helps to hydrate the body and prevent dehydration.

It's essential to note that there is no specific medical treatment for measles. These medications are used to alleviate symptoms, manage complications, and support the recovery process [8][9].

The differential diagnosis of measles includes several conditions that can present with similar symptoms, making it essential to rule out other possibilities before confirming a diagnosis.

According to various sources [1][2], the differential diagnosis of measles includes:

• Rubella: A viral infection that causes a rash and fever, often accompanied by sore throat and cough.
• Roseola: A viral infection that typically affects young children, characterized by a high fever followed by a rash.
• Kawasaki syndrome: A rare condition that primarily affects children under five years old, causing symptoms such as fever, rash, and swelling of the hands and feet.
• Scarlet fever: A bacterial infection caused by Group A Streptococcus, which can cause a distinctive red rash and sore throat.
• Rickettsial infections: Bacterial infections transmitted through ticks or other vectors, which can cause symptoms such as fever, headache, and rash.
• Enteroviral infections: Viral infections that can cause a range of symptoms, including fever, rash, and respiratory issues.
• Adenoviral infections: Viral infections that can cause symptoms such as fever, sore throat, and conjunctivitis.

It's worth noting that the differential diagnosis of measles also includes other conditions that may present with similar symptoms, such as nutritional deficiencies [8], chronic anxiety or depression [8], diabetes type 2 [8], menopause [8], and oral health issues [8].

Proper identification and diagnosis are crucial in eliminating measles virus (MV) and rubella virus (Ruv), as emphasized by various studies [6][7].
