A person may have mumps if they experience or display the following symptoms:

1. Swelling of the cheeks (commonly called “chipmunk cheeks”). This swelling occurs near the ears and jaw, resulting from inflammation of the parotid glands.
2. Fever. A low to moderate fever often accompanies the infection as the body tries to fight the virus.
3. Pain in the ears and jaw. The swollen parotid glands cause discomfort in the surrounding areas, particularly in the ears and jaw.
4. Headache. Many people with mumps experience persistent headaches.
5. Joint pain. Body aches, including pain in the joints, are common and may cause general discomfort.
6. Abdominal pain. Some patients experience stomach pain due to the body’s response to the infection.
7. Dry mouth. Mumps affects saliva production, leading to dryness in the mouth.
8. Difficulty swallowing. Swollen glands can make it painful or challenging to swallow.
9. Loss of appetite. Pain and discomfort in the mouth and jaw often result in reduced appetite.
10. Fatigue. People with mumps may feel unusually tired or fatigued as their body combats the virus.

Mumps symptoms do not appear immediately after infection; they typically emerge between 14 and 25 days after exposure. This delay, known as the incubation period, makes it possible for infected individuals to spread the virus before showing any symptoms themselves.

Diagnostic Procedures for Mumps

Diagnosing mumps involves a combination of symptom assessment, physical examination, and laboratory tests to confirm the presence of the mumps virus. Because mumps symptoms can resemble those of other viral infections, these diagnostic procedures help ensure an accurate diagnosis. Below are the primary steps in diagnosing mumps:

1. Medical history and symptom assessment. A healthcare provider will begin by reviewing the patient’s medical history and symptoms. Common mumps symptoms include swollen cheeks or jaw, fever, muscle aches, fatigue, and headache. The presence of these specific symptoms, especially swelling near the ears and jaw, often raises suspicion for mumps.
2. Physical examination. A physical exam will be conducted to look for swelling in the parotid glands, which are located in front of and below the ears. The characteristic “chipmunk cheeks” caused by swollen salivary glands are a strong indicator of mumps and are usually enough to prompt further testing.
3. Laboratory tests. To confirm the diagnosis, laboratory tests are often conducted. These may include:

• Blood test. A blood sample may be tested to detect antibodies to the mumps virus. The presence of Immunoglobulin M (IgM) antibodies typically indicates an active mumps infection, while Immunoglobulin G (IgG) antibodies suggest past exposure or immunity.
• Saliva or throat swab. A sample from the throat or saliva may be collected and tested for the mumps virus. This test identifies the virus directly and can confirm active infection.
• Urine test. In some cases, a urine sample may be taken to check for the virus, although this method is less common.

4. Imaging tests (rare). In rare cases where there are complications, such as inflammation in other organs (like the pancreas or testicles), imaging tests like ultrasound or MRI may be used to assess the extent of inflammation. This is generally not needed for routine diagnosis but can be helpful in cases of severe or unusual symptoms.

Complications of Untreated Mumps

While mumps often resolves on its own, untreated cases can sometimes lead to serious complications, especially in older children and adults. Complications arise when the mumps virus spreads beyond the salivary glands to affect other organs and body systems, leading to issues that can have lasting impacts on health. Here are some of the main complications associated with untreated mumps:

1. Orchitis (inflammation of the testicles). In males, especially after puberty, mumps can cause inflammation in one or both testicles, leading to pain, swelling, and tenderness. In rare cases, orchitis may result in reduced fertility or, in extreme cases, infertility.
2. Oophoritis and mastitis. In females, mumps can cause inflammation of the ovaries (oophoritis) or the breast tissue (mastitis). Although oophoritis is generally less severe than orchitis, it can lead to abdominal pain and discomfort.
3. Encephalitis (inflammation of the brain). Though rare, mumps can lead to encephalitis, an inflammation of the brain. Symptoms include headache, drowsiness, and seizures, which can be life-threatening if not managed promptly. This condition may result in long-term neurological complications.
4. Meningitis (inflammation of the membranes around the brain and spinal cord). Mumps can lead to viral meningitis, causing symptoms like headache, neck stiffness, and fever. While generally less severe than bacterial meningitis, it can still require hospitalization and supportive care.
5. Hearing loss. In rare cases, untreated mumps can lead to sensorineural hearing loss, usually in one ear. This occurs when the virus affects the inner ear or auditory nerves and may result in permanent hearing damage.
6. Pancreatitis (inflammation of the pancreas). Mumps can sometimes cause inflammation of the pancreas, leading to symptoms like abdominal pain, nausea, and vomiting. While typically temporary, pancreatitis can cause significant discomfort and may require medical intervention.
7. Miscarriage. If a pregnant woman contracts mumps, particularly in the first trimester, there is an increased risk of miscarriage. Pregnant women are generally advised to avoid contact with individuals infected with mumps due to this risk.

While complications from mumps are uncommon, they can be severe and long-lasting if they do occur. Vaccination remains the most effective way to prevent mumps and its potential complications, making it a critical public health measure. Early diagnosis and management are also essential in minimizing risks for those who contract mumps.

Causes of Mumps

The direct cause of mumps is infection with the mumps virus, a type of paramyxovirus. The virus specifically targets the salivary glands, especially the parotid glands located near the jaw and in front of the ears. When a person is exposed to the mumps virus, it enters the body through the respiratory tract—either the nose, mouth, or throat—and travels through the bloodstream to reach the parotid glands, where it multiplies and causes inflammation and swelling.

The virus specifically binds to and infects the cells lining the respiratory and salivary glands, where it replicates. As it multiplies, the virus disrupts normal cell function, causing the infected cells to swell and prompting an immune response that leads to the characteristic pain, swelling, and other symptoms. In most cases, the virus is limited to the salivary glands; however, in severe infections, it can spread further to other organs. In rare cases, the virus may reach the brain (causing encephalitis), the pancreas, and reproductive organs (like the testicles in males and ovaries in females).

Transmission of the mumps virus occurs through close contact with an infected person, who releases virus-laden droplets when coughing, sneezing, or talking. This viral shedding allows the mumps virus to infect new hosts, continuing its spread. The contagious nature of the virus underscores the importance of the MMR vaccine, which effectively prevents the virus from establishing infection in vaccinated individuals.

Prevention of Mumps

Preventing mumps can be challenging due to its highly contagious nature. Simply passing by an infected person on the street can sometimes be enough to contract the virus, even without direct interaction. However, the following precautions are recommended to reduce the risk of contracting mumps:

1. Vaccinate children with the MMR vaccine. The MMR (measles, mumps, rubella) vaccine provides immunity against mumps and is highly effective at preventing infection. The first dose of the MMR vaccine is typically given to children between 12 and 15 months of age, and a second dose is administered between 4 and 6 years old.
2. Practice regular handwashing. Washing hands frequently with soap and water helps remove any virus particles that may have come into contact with your hands, reducing the risk of infection.
3. Cover your nose and mouth around others who are coughing or sneezing. This practice minimizes the risk of inhaling droplets that could contain the mumps virus.
4. Avoid close contact with individuals who have mumps. Keeping a safe distance from infected individuals reduces the likelihood of catching the virus.

Vaccination is the best method of prevention; however, it is not recommended for pregnant women, as the vaccine carries a risk of complications, including miscarriage. Before vaccines were common in the Philippines, it was not unusual for parents to intentionally expose their children to someone with mumps to build natural immunity. Today, the MMR vaccine is a safer and more effective alternative for lifelong immunity without the risk of the illness.

Risk Factors for Mumps

Anyone can contract mumps, but once a person has had mumps, they are typically immune for life, similar to diseases like measles. After a single infection, the body develops immunity that prevents reinfection. However, certain factors can increase the likelihood of contracting mumps, particularly for those without prior immunity or vaccination.

1. Lack of MMR vaccination. The risk of contracting mumps is significantly higher for individuals who have not received the MMR (measles, mumps, rubella) vaccine. Those born before 1957 generally do not need the vaccine, as they likely contracted mumps naturally, giving them lifelong immunity.
2. Young age. Mumps commonly affects children between the ages of 2 and 12. However, adults who were not vaccinated or have not had mumps can also contract the disease.
3. International travel. Visiting countries with limited mumps vaccination programs increases the risk of exposure, especially if vaccination rates are low.
4. Close contact with someone infected. Living with or being in close quarters with someone who has mumps raises the likelihood of contracting the virus, particularly for unvaccinated individuals.
5. Weakened immune system. Individuals with compromised immune systems are more susceptible to mumps, as their bodies may not effectively fight off the virus.

While mumps can affect anyone, maintaining immunity through vaccination is the best way to prevent infection. Those at higher risk should take extra precautions, especially in high-exposure situations, to reduce the likelihood of contracting this highly contagious disease.

Mumps FAQs

Mumps is a viral infection that primarily affects the salivary glands, causing pain and swelling around the jaw and ears. Although rare in countries with widespread vaccination programs, mumps can still occur, especially in areas with lower vaccination rates. Understanding the basics of mumps can help in identifying symptoms early, knowing how it spreads, and taking preventative measures. Below are some frequently asked questions (FAQs) to provide essential information on mumps.
