Human Bocavirus: A New Respiratory Pathogen

Background

Human bocavirus (HBoV), a member of the Parvoviridae virus family, is a newly described human pathogen associated with respiratory illness. Four types of HBoV have been identified: HBoV1, HBoV2, HBoV3, and HBoV4.

HBoV1: A Common Respiratory Pathogen

HBoV1 was first discovered in nasopharyngeal secretions in 2005. It is the most common type of HBoV and is increasingly being recognized as a cause of respiratory illness, particularly in young children. Symptoms of HBoV1 infection include fever, cough, rhinorrhea, and wheezing.

HBoV2, HBoV3, HBoV4

HBoV2, HBoV3, and HBoV4 are less common than HBoV1. However, they have also been associated with respiratory illness. HBoV2 has been reported in cases of pneumonia, while HBoV3 has been found in cases of upper respiratory tract infections. HBoV4 is the least common type of HBoV and has only been associated with a few cases of respiratory illness.

Diagnosis and Treatment

HBoV infection is typically diagnosed by detecting the virus in respiratory secretions using PCR. There is no specific treatment for HBoV infection. However, supportive care, such as rest and fluids, can help to relieve symptoms.
