About Parvovirus Infection (Fifth Disease)
A parvovirus infection is caused by viruses that can infect a variety of animals, including humans. In humans, most parvoviruses infections are caused by parvovirus B19 (B19V). This infection may cause a mild illness with cold-like symptoms, rash, and joint pain. The rash typically appears on the face. The rash is called erythema infectiosum, or more commonly called fifth disease.
These infections can spread through respiratory secretions, saliva, blood products, or from a pregnant person to their baby. The infection and symptoms usually go away on their own. Complications may occur in people with weakened immune systems or who are pregnant.
Parvovirus infection is caused by parvovirus B19, which is an infectious virus that spreads from person to person through nasal secretions, saliva, or spit when a person sneezes or coughs. It can also spread through affected blood or blood products, plasma bone marrow or organ transplant, and from a pregnant person to their baby.
Parvovirus infection commonly occurs in children and adolescents. It can occur in adults but is uncommon. Parvovirus infections more often occur during the spring and summer.
Some people infected with parvovirus B19 do not have symptoms. It is important to know that a person who doesn’t have symptoms is still contagious (can pass the infection on to other people).
When symptoms occur in otherwise healthy individuals, they are usually mild and may include:
- Fever
- Headache
- Cough
- Sore throat
- Fatigue
- Achiness
As the infection progresses or becomes more severe, other symptoms that may occur include:
- Rashes, particularly a bright red rash on the face (“slapped cheek rash”) that may appear a few days after the initial symptoms. Rashes may also appear on the chest, back, buttocks, arms, and legs. The rash may be itchy.
- Joint pain and swelling (polyarthropathy syndrome), which is more common in adults than children
In rare cases, parvovirus infection can cause complications such as severe anemia (not enough red blood cells), which can lead to symptoms like paleness, rapid breathing, rapid pulse, fever, and malaise. People who have a blood disorder (such as sickle cell disease or thalassemia) or a weakened immune system (such as cancer, HIV or organ transplant) have a higher risk of having this complication.
Pregnant individuals who contract parvovirus Infection may also have an increased risk of miscarriage.
It's important to consult with a healthcare provider for an accurate diagnosis and appropriate management.
To diagnose parvovirus infections, healthcare providers may perform the following examinations, tests, and procedures:
- Medical history: The healthcare provider will ask about symptoms and medical history to gather relevant information.
- Physical exam: The healthcare provider will conduct a physical exam to assess any physical signs of infection, such as pain, swelling, or rashes.
- Blood test: A blood test is commonly used to detect the presence of antibodies produced by your body to fight the infection. This test can confirm the diagnosis of a parvovirus infection.
Additional examinations, tests, and procedures may be recommended based upon individual factors or results from initial assessments by the doctor. These may include:
- Pregnancy screening: If you are pregnant and suspected of having parvovirus B19 infection, further testing may be conducted. This may include antibody or PCR testing on amniotic fluid or blood drawn from the umbilical cord. Regular ultrasounds may also be performed to monitor the fetus.
- Imaging studies: Depending on your symptoms and the part of the body being examined, imaging studies such as X-rays or MRIs may be ordered to provide additional information for diagnosis.
Remember, it is important to consult with your healthcare provider for personalized advice regarding examinations, tests, and procedures for parvovirus infection.
Many children and adults with parvovirus infections or fifth disease do not require treatment. For most otherwise healthy people, symptoms are mild and they recover completely.
The goals of treatment for parvovirus infections are to alleviate symptoms, manage complications, and support the body's immune response. Here are the recommended treatments and how they work to achieve these goals:
Medication:
- Fever and pain-reducers: Over-the counter medications like acetaminophen and ibuprofen can help relieve discomfort and reduce fever associated with a parvovirus infection. Check with a healthcare provider regarding the medication and dose that is right for you or your child.
Other Self-care:
- Rest: Getting plenty of rest allows the body to recover and fight off the infection more effectively.
- Hydration: Drinking enough fluids helps prevent dehydration, especially if there is fever or vomiting.
- Practice good hygiene: Wash hands often and cover mouth and nose when sneezing to reduce the chances of spreading parvovirus infections to others.
Other treatment may be needed for people who develop complications. These treatments may include:
- Blood transfusion: Patients with severe anemia caused by a parvovirus infection may require a blood transfusion to restore healthy red blood cell levels.
- Special antibodies: Patients with weakened immune systems may receive special antibodies to help treat the infection. These antibodies can enhance the body's ability to fight off the virus.
It's important to note that parvovirus infections usually resolve on their own without specific treatment. However, these interventions can help manage symptoms and complications. Always consult with your healthcare provider before taking any medications or undergoing any treatments. Medication dosing may be affected by many factors. Check with your healthcare provider about dosing for your individual situation. Other side effects can occur. Check with your healthcare provider or read the information provided with your medication for additional side effect information.
