Fifth disease, also known as erythema infectiosum or “slapped cheek” disease, is a common and generally mild viral illness. At WHAT.EDU.VN, we understand you might have questions about this condition, especially if you’re a parent or caregiver. This guide offers information about fifth disease symptoms, transmission, and management, along with information about infection immunity, and when to seek medical advice.
1. What is Fifth Disease?
Fifth disease is a viral infection primarily caused by parvovirus B19. It is characterized by a distinctive red rash, often appearing on the face, giving the cheeks a “slapped” appearance. While typically mild, understanding the disease, its symptoms, and potential complications is essential. The disease resolves on its own, but for any lingering concerns you can ask the experts at WHAT.EDU.VN.
2. What are the Signs and Symptoms of Fifth Disease?
The symptoms of fifth disease can vary, and some people, especially adults, may not experience any symptoms at all. In children, the disease typically progresses through several stages:
-
Early Symptoms: Initially, fifth disease may resemble a mild cold, with symptoms such as a low-grade fever, fatigue, headache, and runny nose. These symptoms usually appear a week or so before the rash.
-
“Slapped Cheek” Rash: The hallmark of fifth disease is a bright red rash that appears on the cheeks. This rash is usually the most noticeable symptom and gives the disease its characteristic appearance.
-
Body Rash: After the facial rash appears, a lacy, pink rash may develop on the trunk, arms, and legs. This rash is usually flat or slightly raised and may be itchy. The rash may come and go, especially when the skin is warm or exposed to sunlight.
-
Joint Pain: In older children and adults, fifth disease can cause joint pain and swelling, particularly in the hands, wrists, knees, and ankles. Joint symptoms are more common in adults and may last for several weeks or even months.

3. What Causes Fifth Disease?
Fifth disease is caused by parvovirus B19, a common virus that primarily affects humans. The virus spreads through respiratory droplets produced when an infected person coughs or sneezes. It can also spread through contact with contaminated surfaces or objects.
Fifth disease is most contagious during the early stages of the illness, before the rash appears. By the time the rash develops, the person is usually no longer contagious.
4. How Does Fifth Disease Spread?
Parvovirus B19 spreads through close contact with respiratory secretions, such as saliva, sputum, or nasal mucus, from an infected person. This can happen when someone coughs, sneezes, or talks, releasing droplets into the air that can be inhaled by others. Sharing utensils, cups, or other personal items with an infected person can also spread the virus.
The virus can also spread from a pregnant woman to her fetus through the placenta.
5. Who is at Risk of Fifth Disease?
Fifth disease is most common in children between the ages of 5 and 15, but it can affect people of all ages. Outbreaks often occur in schools and daycare centers.
People who are at higher risk of complications from fifth disease include:
- Pregnant women
- Individuals with weakened immune systems
- People with certain blood disorders, such as sickle cell anemia
6. Is Fifth Disease Dangerous During Pregnancy?
Parvovirus B19 infection during pregnancy can pose risks to the fetus, especially during the first trimester. In some cases, the virus can cause fetal anemia, hydrops fetalis (fluid accumulation in the fetus), or even miscarriage.
Pregnant women who suspect they may have been exposed to fifth disease should contact their healthcare provider for evaluation and monitoring.
7. How is Fifth Disease Diagnosed?
Doctors usually can diagnose fifth disease by seeing the rash on the face and body. If someone doesn’t have the rash but does have other symptoms, the doctor may do blood tests to see if is causing them. A blood test can confirm whether a person has been infected with parvovirus B19 and whether they have developed immunity to the virus.
8. What is the Treatment for Fifth Disease?
Fifth disease is a viral infection, so it cannot be treated with antibiotics. In most cases, the illness is mild and self-limiting, meaning it will resolve on its own without specific treatment.
Treatment for fifth disease focuses on relieving symptoms and providing supportive care:
-
Rest: Encourage the person to get plenty of rest.
-
Fluids: Ensure adequate fluid intake to prevent dehydration.
-
Fever Reduction: Acetaminophen or ibuprofen can be used to reduce fever and relieve discomfort. Always follow the dosage instructions carefully.
-
Itch Relief: If the rash is itchy, cool compresses, calamine lotion, or antihistamines may help alleviate the itching.
9. What are the Potential Complications of Fifth Disease?
In most cases, fifth disease is a mild illness that resolves without complications. However, certain individuals are at higher risk of developing complications:
-
Anemia: Parvovirus B19 can temporarily suppress the production of red blood cells, leading to anemia, particularly in individuals with underlying blood disorders.
-
Arthritis: Joint pain and inflammation are more common in adults with fifth disease and can sometimes become chronic.
-
Pregnancy Complications: As mentioned earlier, parvovirus B19 infection during pregnancy can lead to serious complications for the fetus.
10. How Long Does Fifth Disease Last?
The duration of fifth disease can vary from person to person. The initial symptoms, such as fever and fatigue, usually last for a few days. The rash typically appears within 1 to 3 weeks after exposure to the virus and can last for 1 to 3 weeks as well. In some cases, the rash may come and go for several weeks, especially in response to triggers such as sunlight or heat. Joint pain, if present, can last for several weeks or months.
11. Can You Get Fifth Disease More Than Once?
Once a person has had fifth disease, they typically develop lifelong immunity to parvovirus B19. This means they are unlikely to get the disease again.
12. How Can Fifth Disease Be Prevented?
There is no vaccine available to prevent fifth disease. However, practicing good hygiene can help reduce the risk of infection:
- Wash your hands frequently with soap and water, especially after coughing or sneezing.
- Avoid touching your eyes, nose, and mouth.
- Cover your mouth and nose when you cough or sneeze.
- Avoid close contact with people who are sick.
13. When Should You See a Doctor for Fifth Disease?
Most cases of fifth disease are mild and do not require medical attention. However, you should see a doctor if:
- You are pregnant and think you may have been exposed to fifth disease.
- You have a weakened immune system.
- You have a blood disorder, such as sickle cell anemia.
- You develop severe symptoms, such as severe joint pain, shortness of breath, or dizziness.
14. How Does Fifth Disease Affect Adults Differently Than Children?
While the telltale “slapped cheek” rash is common in children, adults often experience fifth disease differently. Here’s a breakdown:
| Feature | Children | Adults |
|---|---|---|
| Rash | Prominent “slapped cheek” rash common | Rash may be less pronounced or absent |
| Joint Pain | Less common | More common; can be severe and prolonged (arthralgia and arthritis) |
| Severity | Generally mild | Can be more debilitating, especially with joint involvement |
| Other Symptoms | Mild fever, cold-like symptoms possible | Fatigue, headache, and flu-like symptoms are possible |
| Complications | Less common in healthy children | Higher risk of complications if immunocompromised or have blood disorders |
15. Is Fifth Disease Related to Other Childhood Rashes?
Fifth disease is distinct from other common childhood rashes like measles, rubella, and chickenpox, each caused by different viruses with unique characteristics:
| Disease | Causative Agent | Key Symptoms |
|---|---|---|
| Fifth Disease | Parvovirus B19 | “Slapped cheek” rash, lacy body rash, possible joint pain |
| Measles | Measles virus | High fever, cough, runny nose, red, blotchy rash starting on the face |
| Rubella | Rubella virus | Mild fever, sore throat, rash starting on the face and spreading downwards |
| Chickenpox | Varicella-zoster virus | Itchy, blister-like rash all over the body |
16. What is the Incubation Period for Fifth Disease?
The incubation period for fifth disease, the time between exposure to the virus and the onset of symptoms, is typically between 4 and 14 days. However, it can range from 3 to 21 days in some cases. People are most contagious during the early stages of the illness, before the rash appears.
17. How Contagious is Fifth Disease?
Fifth disease is most contagious during the early stages, resembling a common cold before the rash appears. Once the characteristic rash emerges, the contagiousness significantly decreases, and individuals are generally no longer considered highly infectious.
18. What is the Significance of the Name “Fifth Disease”?
“Fifth disease” gets its name from being historically listed as the fifth of six common childhood rash illnesses:
- Measles
- Scarlet Fever
- Rubella (German Measles)
- Dukes’ Disease (a debated illness, possibly a form of scarlet fever)
- Fifth Disease (Erythema Infectiosum)
- Roseola (Exanthem Subitum)
This classification highlights its place in the historical understanding of childhood infectious diseases.
19. Are There Any Long-Term Effects of Fifth Disease?
In most cases, fifth disease resolves completely without any long-term effects. However, some individuals may experience prolonged joint pain or arthritis, which can last for several months. People with weakened immune systems or underlying blood disorders may also experience more severe or persistent symptoms.
20. What is the Link Between Fifth Disease and Anemia?
Parvovirus B19, the cause of fifth disease, primarily targets red blood cells. In individuals with pre-existing blood disorders like sickle cell anemia, the virus can trigger a temporary but significant drop in red blood cell production, leading to a severe anemic crisis. This can require hospitalization and treatment.
21. Can Fifth Disease Cause Complications in Immunocompromised Individuals?
Yes, individuals with weakened immune systems, such as those with HIV/AIDS, organ transplant recipients, or those undergoing chemotherapy, are at a higher risk of developing complications from fifth disease. In these individuals, the virus can cause chronic anemia, which can be life-threatening if left untreated.
22. What is Hydrops Fetalis and How is it Related to Fifth Disease?
Hydrops fetalis is a serious condition in which there is an abnormal accumulation of fluid in two or more fetal compartments, such as the skin, heart, and lungs. Parvovirus B19 infection during pregnancy can cause hydrops fetalis in the fetus due to severe anemia.
23. How is Fifth Disease Managed in People with Weakened Immune Systems?
People with weakened immune systems who develop fifth disease may require treatment with intravenous immunoglobulin (IVIG), which contains antibodies that can help fight the virus. Regular monitoring of their red blood cell counts is also important to detect and manage any anemia.
24. Can Adults Transmit Fifth Disease to Children?
Yes, adults can transmit fifth disease to children, even if they don’t have the characteristic rash. Adults may experience milder symptoms or no symptoms at all, but they can still spread the virus to others.
25. What Precautions Should Pregnant Women Take to Avoid Fifth Disease?
Pregnant women can take the following precautions to avoid fifth disease:
- Wash their hands frequently with soap and water.
- Avoid touching their eyes, nose, and mouth.
- Avoid close contact with people who are sick.
- If they work in a high-risk environment, such as a school or daycare center, they should talk to their healthcare provider about additional precautions.
26. Is There a Seasonal Pattern to Fifth Disease Outbreaks?
Yes, fifth disease outbreaks tend to occur more frequently in the late winter and early spring. This may be due to increased close contact among people during these months.
27. How Can Schools and Daycares Prevent the Spread of Fifth Disease?
Schools and daycares can take the following steps to prevent the spread of fifth disease:
- Encourage frequent handwashing among students and staff.
- Teach students and staff to cover their mouths and noses when they cough or sneeze.
- Clean and disinfect frequently touched surfaces.
- Exclude sick children and staff from school or daycare.
28. What is the Role of Blood Tests in Diagnosing Fifth Disease?
Blood tests can be used to diagnose fifth disease, especially in individuals who do not have the characteristic rash. The tests can detect the presence of parvovirus B19 antibodies, which indicate a current or past infection.
29. Are There Any Alternative Names for Fifth Disease?
Yes, fifth disease is also known as erythema infectiosum, slapped cheek syndrome, and parvovirus B19 infection.
30. What is the Prognosis for Fifth Disease?
The prognosis for fifth disease is generally excellent. Most people recover completely without any long-term effects. However, individuals with weakened immune systems or underlying blood disorders may experience more severe or persistent symptoms.
31. What is the Best Way to Manage Joint Pain Associated with Fifth Disease?
Joint pain associated with fifth disease can be managed with over-the-counter pain relievers, such as acetaminophen or ibuprofen. In some cases, a doctor may prescribe stronger pain medications or anti-inflammatory drugs.
32. Can Fifth Disease Affect the Heart?
In rare cases, fifth disease can affect the heart, leading to myocarditis (inflammation of the heart muscle) or pericarditis (inflammation of the sac surrounding the heart). These complications are more common in individuals with weakened immune systems.
33. How Does Fifth Disease Compare to Hand, Foot, and Mouth Disease?
Fifth disease and hand, foot, and mouth disease are both common viral illnesses that affect children, but they are caused by different viruses and have different symptoms. Fifth disease is caused by parvovirus B19 and is characterized by a “slapped cheek” rash, while hand, foot, and mouth disease is caused by coxsackieviruses and is characterized by blisters on the hands, feet, and mouth.
34. Can Fifth Disease Cause Neurological Problems?
In very rare cases, fifth disease can cause neurological problems, such as encephalitis (inflammation of the brain) or meningitis (inflammation of the membranes surrounding the brain and spinal cord). These complications are more common in individuals with weakened immune systems.
35. How Does Fifth Disease Affect People with Sickle Cell Anemia?
Parvovirus B19 infection can cause a temporary but severe drop in red blood cell production in people with sickle cell anemia, leading to a potentially life-threatening anemic crisis. These individuals require close monitoring and may need blood transfusions.
36. Is There a Link Between Fifth Disease and Miscarriage?
Yes, parvovirus B19 infection during pregnancy can increase the risk of miscarriage, especially during the first trimester. The virus can cause severe anemia in the fetus, leading to fetal death.
37. What Research is Being Done on Fifth Disease?
Researchers are continuing to study fifth disease to better understand the virus, its transmission, and its potential complications. They are also working on developing new treatments and prevention strategies.
