Fatal HBoV-1 infection in adult female cystic fibrosis patient

Human bocavirus infections in paediatric patients in a tertiary care hospital in Kerala, India

Human bocaviruses (HBoVs) can cause respiratory illness in young children. Although the first HBoV infection in India was reported in 2010, very little information is available about its prevalence, clinical features, or geographic distribution in this country. This study was conducted using 136 respiratory samples from paediatric patients in a tertiary care hospital in Kerala, 21 of which tested positive for HBoV1 and were further characterized through VP1/VP2 gene sequencing. We found that different strains of HBoV1 are co-circulating in the region and that HBoV1 can be detected in children with severe acute respiratory infections, either alone or coinfections with other pathogens, without any significant differences in their clinical characteristics.

Severe Human Bocavirus-Associated Pneumonia in Adults at a Referral Hospital, Seoul, South Korea

We report a case series of severe human bocavirus–associated pneumonia in adults in Seoul, South Korea. The virus accounted for 0.5% of all severe pneumonia cases. Structural lung disease and hematologic malignancy were common underlying diseases. Overall death rate was 54.5%. Higher death rates were associated with co-infection (83.3%) and immunocompromise (80.0%).

High-dose glucocorticoid treatment of near-fatal bocavirus lung infection results in rapid recovery

Human bocavirus (HBoV), which belongs to Parvoviridae, is a well-defined pathogen of respiratory infections, particularly in young children [1]. In contrast, the frequency of HBoV infections in adults with respiratory symptoms is virtually unknown and its causative role in respiratory failure is debated [1, 2]. Furthermore, the observation that dexamethasone is beneficial in COVID-19 patients with respiratory failure requiring respiratory support has gained great interest [3]. However, whether glucocorticoid treatment is useful in other severe viral respiratory diseases is a matter of controversy [4].

Human bocavirus (HBoV) has to be considered a life-threatening pathogen in adults with atypical pneumonia. Pulsed high-dose glucocorticoid treatment may be beneficial in patients suffering from severe pulmonary disease caused by HBoV or other viruses.https://bit.ly/3epiMyO

Severe Human Bocavirus 1 Respiratory Tract Infection in an Immunodeficient Child With Fatal Outcome

We report a case of lower respiratory tract infection with human bocavirus 1 (HboV1) in an immunodeficient 6-month-old boy leading to respiratory failure with fatal outcome. Polymerase chain reaction of serum/tracheal secretions revealed exceptionally high HboV1-DNA levels and immunoassays showed seroconversion indicating an acute primary HboV1 infection. All assays for other pathogens were negative, strongly suggesting that HboV1 was the causative agent in this case.
