U.S. CDC issues warning on rising cases of Parvovirus B19, also known as "spanked butts rash"
or “slapped cheeks rash” virus
Often referred to as "slapped cheek disease" or "spanked butts rash," this virus has seen a notable increase in cases, particularly among children aged 5 to 9. The CDC's warning follows reports of rising infections across the United States and Europe, highlighting the need for heightened vigilance, especially among vulnerable populations.
Although Parvovirus B19 infections are also rising exponentially across many countries in Europe, the local mainstream media and
Medical News outlets have not been reporting any coverages on this.
What is Parvovirus B19?
Parvovirus B19, also known as fifth disease, is a common virus spread through respiratory droplets. Its nickname "slapped cheek disease" "spanked butts rash," or comes from the distinctive bright red rash that appears on the cheeks, buttocks, thighs and trunks of infected individuals, particularly children.

The virus primarily affects children, but adults can also contract it, with different manifestations.
The U.S. CDC reports that by the age of 20, about 50% of adults in the United States have detectable antibodies against Parvovirus B19, a figure that rises to over 70% by age 40. Those who work in close contact with children, such as teachers and daycare workers, are at a higher risk of infection.
The Impact of COVID-19 on Parvovirus B19 Activity
The COVID-19 pandemic, with its widespread public health measures, including mask-wearing, social distancing, and enhanced hygiene practices, led to a significant decline in many respiratory illnesses, including Parvovirus B19. However, as these measures have been relaxed, the CDC has observed a resurgence of the virus. The proportion of people with antibodies indicating recent infection fell below 3% during 2022-2024 but has surged to 10% by June 2024, with the most significant increase seen in children aged 5 to 9.
This rise in cases has not only been observed in the U.S. but also in Europe. The European Centre for Disease Prevention and Control (ECDC) reported unusually high numbers of Parvovirus B19 cases in 14 countries during the first quarter of 2024, prompting similar warnings across the continent.
Symptoms and Phase
s of Parvovirus B19 Infection
Parvovirus B19 infection typically presents in two distinct phases. The first phase begins about a week after infection, with symptoms such as fever, muscle aches, malaise, and sore throat, lasting about five days. During this phase, individuals are most contagious.
The second phase of the illness, occurring about a week later, is characterized by the appearance of the hallmark "slapped cheek" rash in children, followed by a body rash or joint pain. Adults, on the other hand, may experience joint pain and a rash on the trunk but often do not develop the facial rash seen in children.
While many people infected with Parvovirus B19 are asymptomatic or experience mild symptoms, the virus can lead to severe complications in certain populations.
High-Risk Groups and Complications
Parvovirus B19 poses a significant risk to certain groups, including pregnant individuals, those with weakened immune systems, and individuals with chronic hemolytic conditions such as sickle cell disease.
-Pregnancy: Infection during pregnancy can have serious consequences for the fetus, including severe fetal anemia, hydrops fetalis, miscarriage, or stillbirth. The risk of adverse fetal outcomes is estimated to be around 5-10% for infected pregnant individuals, with the greatest risk occurring during the first half of pregnancy.
-Immunocompromised Individuals: Those with compromised immune systems, such as individuals undergoing cancer treatments, organ transplant recipients, or those with HIV, are at risk of developing severe anemia, a life-threatening condition characterized by a significant drop in red blood cells.
-Chronic Hemolytic Conditions: Individuals with conditions like sickle cell disease may experience aplastic anemia, where the production of red blood cells is severely impaired, leading to an anemia crisis.
Current State and CDC Recommendations
With the increase in Parvovirus B19 cases, the CDC is urging healthcare providers to be vigilant in diagnosing and managing the virus, particularly in high-risk groups. There is currently no vaccine available for Parvovirus B19, and treatment is primarily supportive, focusing on alleviating symptoms.
For the general public, the CDC recommends adhering to standard precautions to prevent the spread of respiratory illnesses. These include frequent hand washing, keeping common surfaces clean, and covering the mouth and nose when coughing or sneezing. For those who develop symptoms, it is advised to stay away from others until symptoms improve and they have been fever-free for at least 24 hours without medication.
Pregnant individuals, those with weakened immune systems, and those with chronic hemolytic disorders are encouraged to take additional precautions, such as wearing masks in public settings and seeking immediate medical care if they develop symptoms of Parvovirus B19.
Global Implications and Continued Vigilance
The recent surge in Parvovirus B19 cases is not confined to the United States. Earlier this year, several European countries, including France, Spain, and Germany, reported spikes in infections. The global nature of this resurgence underscores the importance of continued vigilance and the need for public health measures to mitigate the spread of the virus.
In addition to the general population, healthcare providers are advised to monitor for cases of Parvovirus B19, especially in pregnant patients and those with underlying health conditions. The CDC's health advisory serves as a reminder that while Parvovirus B19 is often mild, it can have serious implications for specific groups, necessitating early diagnosis and appropriate management.
Conclusion
As Parvovirus B19 activity rises, the importance of public health awareness and preventive measures cannot be overstated. The CDC's warning highlights the need for vigilance, particularly among vulnerable populations, to mitigate the risks associated with this contagious virus. With no vaccine available, the focus remains on prevention, early detection, and supportive care for those affected.
