“…A systematic review with meta‐analysis in China found a prevalence of 18.7% (95% CI 17.1‐20.5, 135 studies from 2010 to 2015) attributable to HRSV . Another systematic review with meta‐analysis of 21 studies (1996‐2013) in Iran yielded to a prevalence of 18.7% .

AimThe epidemiology of human respiratory syncytial virus (HRSV) infection has not yet been systematically investigated in Africa. This systematic review and meta‐analysis are to estimate the prevalence of HRSV infections in people with acute respiratory tract infections (ARTI) in Africa.MethodWe searched PubMed, EMBASE, Africa Journal Online, and Global Index Medicus to identify observational studies published from January 1, 2000, to August 1, 2017. We used a random‐effects model to estimate the prevalence across studies. Heterogeneity (I 2) was assessed via the chi‐square test on Cochran's Q statistic. Review registration: PROSPERO CRD42017076352.ResultsA total of 67 studies (154 000 participants) were included. Sixty (90%), seven (10%), and no studies had low, moderate, and high risk of bias, respectively. The prevalence of HRSV infection varied widely (range 0.4%‐60.4%). The pooled prevalence was 14.6% (95% CI 13.0‐16.4, I 2 = 98.8%). The prevalence was higher in children (18.5%; 95% CI 15.8‐21.5) compared to adults (4.0%; 95% CI 2.2‐6.1) and in people with severe respiratory tract infections (17.9%; 95% CI 15.8‐20.1) compared to those with benign forms (9.4%; 95% CI 7.4‐11.5); P‐values <0.0001. The HRSV prevalence was not associated with sex, subregion in Africa, setting, altitude, latitude, longitude, and seasonality.ConclusionThis study suggests a high prevalence of HRSV in people with ARTI in Africa, particularly among children and people with severe clinical form. All innovative strategies to curb the burden should first focus on children which present the highest HRSV‐related burden.

“…These viruses are a significant cause of morbidity and mortality globally, especially among children in developing countries [1][2][3][4][5][6][7]. RSV is the most important pathogenic infection of childhood worldwide, causing a variety of manifestations from mild upper respiratory tract illnesses or otitis media to severe and potentially lifethreatening lower respiratory tract illnesses [6,[8][9][10][11]. Four PIV types (PIV1-4) have been identified [12,13].…”

To investigate the features of paramyxovirus respiratory syncytial virus (RSV), parainfluenza virus (PIV), and human metapneumovirus (HMPV) infection and determine the effect of meteorological conditions in Guangzhou, a subtropical region of southern China. We collected 11,398 respiratory samples from hospitalized pediatric patients with acute respiratory illness between July 2009 and June 2016 in Guangzhou. The samples were tested simultaneously for 18 respiratory pathogens using real-time PCR. Local meteorological data were also collected for correlation analysis. Of 11,398 patients tested, 5606 (49.2%) patients tested positive for one or more pathogens; RSV, PIV, and HMPV were the first, sixth, and ninth most frequently detected pathogens, in 1690 (14.8%), 502 (4.4%), and 321 (2.8%) patients, respectively. A total 17.9% (4605/5606) of patients with positive results had coinfection with other pathogens. Significant differences were found in the prevalence of RSV, PIV, and HMPV among all age groups (p < 0.001). RSV and HMPV had similar seasonal patterns, with two prevalence peaks every year. PIV appeared alternatively with RSV and HMPV. Multiple linear regression models were established for RSV, PIV, and HMPV prevalence and meteorological factors (p < 0.05). RSV and PIV incidence was negatively correlated with monthly mean relative humidity; RSV and HMPV incidence was negatively correlated with sunshine duration; PIV incidence was positively correlated with mean temperature. We described the features of paramyxovirus infection in a subtropical region of China and highlighted the correlation with meteorological factors. These findings will assist public health authorities and clinicians in improving strategies for controlling paramyxovirus infection.

Background: Acute respiratory tract infection is associated with significant morbidity, mortality, and economic loss worldwide. Viral infections seem to be responsible for 80% of the cases. There are several reports on the influence of dual or multiple respiratory viral infections on the severity of disease in childhood. Objectives: A limited number of studies have been conducted on co-infection of Adenovirus (AdV) with coxsackievirus, human bocavirus (HBoV) and Mycoplasma pneumoniae (MP) in Iran. To address this, the present article focuses on both the etiology and epidemiology of multiple microbial respiratory infections (coxsackievirus, HBoV, MP and influenza virus) and their clinical significance in young Iranian children with confirmed AdV infection. Patients and Methods: Molecular detection of HBoV, coxsackievirus, MP and influenza virus was performed by conventional PCR in 71 respiratory adenovirus-positive samples obtained from children younger than 5 years of age. Results: Among the 71 adenovirus-positive samples, 6 (8.4%) were co-infected, three were co-infected with MP and three of which were co-infected with influenza A/H3N2. Of the six patients with co-infection, four were male and two were female; three patients were less than 1 year of age and the remaining were 2, 3 and 4 years of age. Moreover, there were two inpatients and four outpatients. Conclusions: Although several studies have investigated viral respiratory co-infection, no study has evaluated the rate of respiratory co-infections in adenovirus-positive samples from children younger than 5 years. However, this study has filled this gap, the the number of co-infections were too small to draw any definite conclusions. Therefore, large-scale studies using bigger samples are required to understand the clinical significance of polymicrobial acute respiratory infections.
