Mais comme le montre une étude récente réalisée à Hong Kong, la fréquence des infections liées à chacun de ces coronavirus et leur saisonnalité peuvent varier d'une année à l'autre et probablement aussi d'un pays à l'autre[45].Chez les enfants hospitalisés pour une infection respiratoire, le bocavirus est détecté avec une fréquence qui varie de 1,4 % à 10 % selon les études[46].

In Normandy (France), human respiratory syncytial virus (hRSV) was detected in 64.1% of acute bronchiolitis in hospitalized children, rhinovirus in 26.8%, human metapneumovirus (hMPV) in 7.6%, and parainfluenza virus (PIV) in 3.4%. The viruses causing acute bronchiolitis in the community were hRSV (42%), rhinovirus (19.5%), coronavirus (8%), PIV (3.5%), and hMPV (2.5%). In 53.7% of the cases, hRSV infected infants (86.9%), 53.7% being less than 6 months of age. Of the hRSV cases, 48.2% were detected in November and December and 44.5% in January and February. The hRSV epidemic started the 1st or 2nd week of October but it varied from one year to another and from one region to another. hRSV acute bronchiolitis increased from 261 cases in epidemics from 1999-2003 to 341 cases from 2004-2009. Rhinoviruses gave acute bronchiolitis in 38.4% of cases. A rate of 54.6% of viruses was detected in September and October and 38.5% in March and April. A total of 34.2% of infected infants were under 6 months of age, 37.8% between 6 months and 2 years, and 19.5% were between 2 and 5 years old. hMPV epidemics coincided with hRSV epidemics, but they accounted for one-sixth the number of cases. HMPV infected infants (74%) who were older than those infected with hRSV, and the diagnosis was bronchiolitis (59%) and pneumonia (17%). PIV infections (about 100 cases per year) included PIV3 (62.7%), PIV1 (25.3%), and PIV2 (7.3%). PIV1 infections occurred every 2 years in the fall. PIV3 infections were observed every year during the fall and winter, with peaks of infections in the spring in the years without PIV1. There were acute cases of bronchiolitis in 29.8% of PIV3 infections and 18.3% in PIV1 infections.

“…En abscisse : répartition mensuelle entre 1999 et 2009. Une étude caennaise de 16 infections à bocavirus a trouvé 7 BA, 2 crises d'asthme et 1 pneumonie[46]. La gravité de la BA, mesurée en fréquence respiratoire ou en SaO 2 , n'est pas statistiquement différente entre les 2 atteintes virales[43].…”

“…Another study performed PCR for HBoV on specimens otherwise negative for respiratory viruses. Low rates of HBoV detection were noted but of the 16 patients with HBoV detection and with clinical data available, 28% of patients had wheezing and two patients had a clinical diagnosis of asthma [73]. Finally, in a retrospective study from Italy, nasopharyngeal specimens from 22 adult patients with severe asthma were available for testing.…”

Background Viral respiratory infection has long been known to influence the occurrence of asthma exacerbations. Over the last twenty years much effort has been put into clarifying the role that viral respiratory infections play in the eventual development of asthma. Scope of Review In this review we give a general background of the role of viruses in the processes of asthma exacerbation and asthma induction. We review recent additions to the literature in the last three years with particular focus on clinical and epidemiologic investigations of influenza, rhinovirus, bocavirus, respiratory syncytial virus, and metapneumovirus. Major Conclusions The development of asthma emerges from a complex interaction of genetic predisposition and environmental factors with viral infection likely playing a significant role in the effect of environment on asthma inception. General Significance Further understanding of the role that viruses play in asthma exacerbation and inception will contribute to decreased asthma morbidity in the future.
