Introduction: Human Erythrovirus (parvovirus) B19 infection can produce symptoms similar to those produced by Dengue, Chikungunya, and Zika viruses, making clinical diagnosis difficult. The importance of erythrovirus B19 in human pathology has been increased and reported in numerous studies published globally.
Methods: The B19V infection was investigated by real-time PCR in sera samples from patients with signs and symptoms related to classic arboviral symptoms. This study was conducted to provide information on the genetic diversity of Human Erythrovirus B19 (B19V) circulating in the state of Mato Grosso do Sul, Midwest region of Brazil, from 2017 to 2022. A total of 773 sera samples of patients with negative diagnostic results for Dengue, Chikungunya, and Zika, during the study period were analyzed.
Results: Erythrovirus DNA was found in 10.6% (82/773) of patients, among them 10 were pregnant women. Four samples were completely sequenced, and the other five partially, to genotype by phylogenetic reconstruction. All samples belong to worldwide dispersed genotype 1, subgenotype 1a.
Discussion: The findings of the study demonstrate the importance of including B19V in differential laboratory diagnosis for epidemiological purposes and appropriate patient management. The diagnosis for B19V should be performed, particularly among pregnant women, immunocompromised patients, and individuals with hemolytic diseases, given that the infection is more severe in these cases.

The development of a protective HIV vaccine remains a challenge given the high antigenic diversity and mutational rate of the virus, which leads to viral escape and establishment of reservoirs in the host. Modern antigen design can guide immune responses towards conserved sites, consensus sequences or normally subdominant epitopes, thus enabling the development of broadly neutralizing antibodies and polyfunctional lymphocyte responses. Conventional epitope vaccines can often be impaired by low immunogenicity, a limitation that may be overcome by using a carrier system.

Parvovirus B19 (B19V) is a significant pathogen responsible for a wide range of clinical manifestations, particularly in children and pregnant women. While B19V is most commonly recognized as the cause of Fifth disease, a mild erythematous illness in children, its clinical impact extends far beyond this condition. B19V can lead to severe complications, including transient aplastic crisis in individuals with chronic hemolytic anemias, arthralgia, and more severe joint diseases.

Several cases of glomerulonephritis occurring after infection with human parvovirus B19 (PVB19) have been reported. However, the pathogenesis and clinicopathological features of PVB19-related glomerulonephritis remain elusive. We describe the case of a 34 year-old woman who showed nephrotic syndrome and microscopic hematuria 10 days after PVB19 infection.

Human parvovirus B19 typically causes erythema infectiosum, but unusual exanthems and hemorrhagic manifestations, such as purpuric-petechial rashes, have also been reported. PVB19-associated purpuric-petechial eruption (PAPPE) should be recognized as a distinct clinical feature of primary parvovirus B19 infection and considered in the differential diagnosis of patients with febrile purpura. This report aims to highlight several scenarios of B19V-associated petechial and purpuric rashes, which may present to pediatric departments during outbreaks.

Myasthenia gravis (MG) is a rare autoimmune disorder characterised by muscle weakness resulting from autoantibody-mediated disruption of the neuromuscular junction. Notably, it is also frequently associated with thymic pathology. This study explores the relationship between MG and DNA viruses in the thymus, employing targeted NGS and qPCR to analyse thymic tissue samples from both MG patients and healthy controls.
