obsolete Mumps virus infectious disease

Mumps Virus Infectious Disease: A Historical Overview

Mumps was a highly contagious viral disease caused by the mumps virus, which primarily affected children and young adults. The disease was characterized by inflammation in peripheral nerves, resulting from infection with the Mumps virus.

• Definition: Mumps is an infectious disease that results in inflammation located in peripheral nerves, has material basis in Mumps virus (1, 3).
• Viral Characteristics: The Mumps virus is a paramyxovirus, belonging to the same group as parainfluenza and Newcastle disease viruses. It produces antibodies that cross-react with mumps virus (2).

Symptoms and Complications

The initial symptoms of mumps were non-specific and included fever, headache, malaise, muscle pain, and swelling of the salivary glands (parotitis) (6). Inflammation in other parts of the body was also common. Complications such as meningitis, encephalitis, and orchitis were rare but serious consequences of mumps infection.

• Complication Rates: The case fatality ratio for mumps was 1.6–3.8/10,000, with most fatalities occurring in persons with encephalitis (10).
• Morbidity: The major morbidity from mumps was due to complications of meningitis, encephalitis, and orchitis (10).

Epidemiology

Before the widespread use of the mumps vaccine, most children contracted mumps by adolescence. The introduction of the mumps vaccination program in the United States in 1967 led to a significant decrease in reported cases.

• Vaccine Impact: Reported cases decreased from 152,209 in 1968 to 231 in 2003 (11).
• Reemergence: However, case counts have been increasing over the past 20 years, indicating a reemerging infectious disease (12).

Conclusion

Mumps was a vaccine-preventable, highly contagious viral disease that primarily affected children and young adults. The introduction of the mumps vaccine led to a significant decrease in reported cases but has seen a resurgence in recent years.

Common Signs and Symptoms of Mumps

Mumps, an infectious viral disease, typically presents with a range of symptoms that can vary in severity. The following are the common signs and symptoms associated with mumps:

• Fever: A high temperature is often one of the first symptoms to appear, usually within 2-4 weeks after exposure to the virus [1][3].
• Headache: Mild to severe headaches are a common symptom of mumps, often accompanied by fever [1][5].
• Muscle aches or pain: Pain and tenderness in the muscles, particularly in the neck and back area, can occur due to inflammation caused by the virus [2][7].
• Fatigue: Feeling tired or exhausted for no apparent reason is another common symptom of mumps [3][13].
• Loss of appetite: A decrease in appetite or feeling uninterested in food can also be a sign of mumps infection [1][5].
• Swelling of the salivary glands: The most distinctive feature of mumps is the swelling and tenderness of one or both parotid (salivary) glands, which can cause puffy cheeks and a tender jaw [2][4].

Rare but Serious Complications

While rare, mumps infection can lead to more severe complications in some individuals, including:

• Brain inflammation: Inflammation of the brain, known as encephalitis, is a serious complication that requires immediate medical attention [11].
• Central nervous system involvement: Mumps virus can also infect the central nervous system, leading to meningitis or other neurological disorders [14].

Incubation Period and Age Groups Affected

The incubation period of mumps, which is the time between exposure to the virus and the onset of symptoms, typically ranges from 12-25 days. Mumps most commonly affects children aged 2-12 who have not been vaccinated against the disease [14].

Diagnostic Tests for Mumps Virus Infection

Mumps, an acute infectious disease caused by the mumps virus, has been largely eradicated in many parts of the world due to widespread vaccination programs. However, in areas where the disease is still prevalent or in cases of suspected infection, diagnostic tests are essential for confirming the diagnosis.

Types of Diagnostic Tests

Several types of diagnostic tests can be used to detect mumps virus infection:

• Serologic testing: This involves detecting IgM and IgG antibodies against the mumps virus in a patient's blood sample. Serologic testing is often used as a first-line approach, but it may not always provide accurate results due to cross-reactivity with other viruses or previous exposure to the vaccine.
• Real-time RT-PCR (rRT-PCR): This molecular assay can detect mumps viral RNA in a patient's saliva or blood sample. rRT-PCR is more sensitive and specific than serologic testing, making it a preferred method for diagnosing mumps infection.
• Viral culture: This involves growing the virus from a patient's saliva or other bodily fluids to confirm the diagnosis.

Other Diagnostic Methods

In addition to these tests, other methods can be used to diagnose mumps infection:

• Clinical evaluation: A healthcare provider may use clinical symptoms and signs, such as fever, headache, and swelling of the parotid glands, to suspect mumps infection.
• Imaging studies: Imaging techniques like ultrasound or CT scans may be used to visualize the affected areas.

Importance of Accurate Diagnosis

Accurate diagnosis is crucial for managing mumps infection effectively. Misdiagnosis can lead to delayed treatment and potentially serious complications. Therefore, healthcare providers should consider a combination of clinical evaluation, serologic testing, and molecular assays like rRT-PCR when diagnosing mumps infection.

Current Treatment Options for Mumps

Unfortunately, there are no specific medicines to treat the mumps virus itself [3]. However, treatment focuses on relieving symptoms and making patients more comfortable.

• Pain relief: Medications like ibuprofen (Advil, Motrin, NeoProfen) can help alleviate mild to moderate pain and fever [5].
• Supportive care: Drinking plenty of fluids and getting plenty of rest can also help manage symptoms [8].

It's essential to note that antibiotics are ineffective against viral infections like mumps [6]. Treatment is generally focused on managing symptoms until the infection resolves on its own.

Complications and Special Cases

While rare, complications from mumps can occur, especially in adults. In such cases, treatment may involve addressing specific issues, such as:

• Pneumonia: A serious complication that requires hospitalization and antibiotic treatment [4].
• Meningitis: Another severe complication that requires prompt medical attention and treatment [4].

In these situations, treatment is focused on managing the underlying condition rather than targeting the mumps virus itself.

Prevention Remains Key

While there are no specific treatments for mumps, prevention through vaccination remains the most effective way to prevent the disease. The live attenuated mumps virus vaccine is recommended at any age on or after the first birthday [2].

Differential Diagnosis of Obsolete Mumps Virus Infectious Disease

The differential diagnosis for obsolete Mumps virus infectious disease involves considering various conditions that may present with similar symptoms. According to search results [7], the following conditions should be considered in the differential diagnosis:

• Allergic reaction
• Mastoiditis
• Measles
• Pediatric HIV infection

Additionally, as mentioned in search result [5], a differential diagnosis may also include other conditions such as:

• Cellulitis
• Chronic Fatigue Syndrome
• Cough
• Diarrhea
• Endocarditis
• Fever of Unknown Origin
• Food Poisoning

It's worth noting that the information on differential diagnoses of Mumps is based on expert opinion in the BMJ Best Practice guideline Mumps [13] and narrative review articles Mumps and the UK epidemic 2005 [Gupta, 2005], Mumps [Hviid, 2008], Mumps: a resurgent disease with protean manifestations [Senanayake, 2008].

Key Points to Consider

• A comprehensive differential diagnosis is essential for accurate diagnosis of obsolete Mumps virus infectious disease.
• Various conditions may present with similar symptoms, making it crucial to consider multiple possibilities.
• Expert opinion and review articles provide valuable insights into the differential diagnoses of Mumps.
