Abstract Background This study evaluated the yield of testing NP vs BAL specimens using a multiplex PCR respiratory viral panel (RVP). Methods A retrospective chart review was conducted on all patients from 10/2017-3/2021 who had both an NP swab and BAL tested by RVP within a 4-week period. Results There were 477 cases where patients had both an NP and BAL specimen tested by RVP. Results were NP-/BAL- for 361 (76%) cases, NP+/BAL+ for 58 (12%), NP-/BAL+ for 40 (8%), and NP+/BAL- for 18 (4%). For NP+/BAL+, NP-/BAL+, and NP+/BAL-, respectively, rhinovirus was detected in 23 (40%), 3 (8%), and 16 (89%) cases (p< 0.001); influenza A or B in 9 (16%), 7 (18%), and 0 (0%) (ns); adenovirus in 3 (5%), 10 (25%), and 2 (11%) (p< 0.05); metapneumovirus in 9 (16%), 8 (20%), 2 (11%) (ns); RSV in 8 (14%), 6 (15%), and 1 (6%) (ns); and, parainfluenza in 7 (12%), 6 (15%), and 1 (6%) (ns), respectively. Average ages were 48, 48, and 48 years; numbers of males were 34 (58%), 28 (70%), and 11 (61%); immunocompromised were 56 (97%), 37 (92%), and 17 (94%); and, 16 (28%), 10 (25%), and 6 (33%) had an active malignancy, respectively (all ns). Average symptom durations prior to presentation were 7.0, 13.1, and 9.6 days (ns); pulmonary exams were abnormal in 35 (60%), 24 (60%), and 5 (28%) cases (p< 0.05); shortness of breath (SOB) was present in 40 (69%), 25 (62%), and 8 (44%) (ns); lower respiratory tract infection (LRTI) symptoms were absent in 1 (2%), 12 (30%), and 8 (45%) cases (p< 0.01); when spirometry values were available, they were reduced in 28/31 (90%), 15/19 (79%), and 3/8 (37%) cases (p< 0.05); and, mean SpO2 levels were 91.5%, 93.9%, and 93.7% (ns), respectively. Mean temperatures were 99.0F, 99.0F, and 99.1F (ns); chills, sweats, and malaise were present in 27 (47%), 13 (33%), and 3 (17%) cases (p< 0.05); GI symptoms were present in 20 (34%), 5 (13%), and 10 (56%) cases (p< 0.05); and, acute kidney injury was present in 38 (66%), 13 (33%), and 6 (33%) cases (p< 0.05), respectively. Conclusion Most (88%) RVP test results were concordant between NP and BAL. There were significant differences between cases of NP+/BAL+, NP-/BAL+, and NP+/BAL-. Rhinovirus and GI symptoms were more common for NP+/BAL- vs NP-/BAL+. Conversely, pulmonary exams were more often abnormal and spirometry values reduced for NP-/BAL+ vs NP+/BAL-.

Differentiation between abacavir hypersensitivity and viral respiratory infections is problematic. Fifteen cases of abacavir hypersensitivity were matched to 30 controls with culture proven influenza A with no abacavir exposure. Rash was associated with hypersensitivity (odds ratio [OR] = 13.1, P = 0.02) as was the presence of nausea (OR = 30, P < 0.001), vomiting (OR = 17.1, P = 0.001) or diarrhoea (OR = 22, P < 0.001). The number of gastrointestinal symptoms was also predictive of hypersensitivity reaction ( P < 0.001). Respiratory symptoms (cough, sore throat, or dyspnoea) were not associated with abacavir hypersensitivity (OR = 0.08, P = 0.001). Multivariate analysis confirmed the following associations for abacavir hypersensitivity: the number of gastrointestinal symptoms (OR = 8.6, P = 0.0032), cough (OR = 0.039, P = 0.02) and rash (OR = 16.9, P = 0.07). Abacavir hypersensitivity is strongly associated with gastrointestinal (GI) symptoms. Cough without GI symptoms is associated with influenza.

Abstract Objective Although healthcare-associated (HA) viral respiratory infections (VRIs) are common in pediatrics, no benchmark for comparison exists. We aimed to determine, compare, and assess determinants of unit-specific HA-VRI incidence rates in 2 children’s hospitals. Methods This study was a retrospective comparison of prospective cohorts. The Montreal Children’s Hospital and the Cohen Children’s Medical Center of New York perform prospective surveillance for HA-VRI using standardized definitions that require the presence of symptoms compatible with VRI and virus detection. Cases detected between April 1, 2010, and March 31, 2013, were identified using surveillance databases. Annual incidence rates were calculated, and a generalized estimating equation model was used to assess determinants of HA-VRI rates. Results The overall HA-VRI rate during the 3-year study period was significantly higher at Montreal Children’s Hospital than that at Cohen Children’s Medical Center of New York (1.91 vs 0.80 per 1000 patient-days, respectively;P &lt; .0001). Overall, the HA-VRI incidence rate was lowest in the neonatal intensive care unit. Rates in the pediatric intensive care, oncology, and medical/surgical units were similar. The most common etiology of HA-VRI at both institutions was rhinovirus (49% of cases), followed by parainfluenza virus and respiratory syncytial virus. Hospitals with less than 50% single rooms had HA-VRI rates 1.33 (95% confidence interval, 1.29–1.37) times higher than hospitals with more than 50% single rooms for a given unit type. Conclusions HA-VRI rates were substantial but different among 2 children’s hospitals. Future studies should examine the effect of HA-VRI and evaluate best practices for preventing such infections.

AbstractWe investigated the effect of annual winter visitor restrictions on hospital respiratory virus transmission. The healthcare-associated (HA) viral respiratory infection (VRI) transmission index (number of HA VRIs per 100 inpatient community-associated VRIs) was 59% lower during the months in which visitor restrictions were implemented. These data prompt consideration for instituting year-round visitor restrictions.

SUMMARYViral respiratory infections continue to pose a major global healthcare burden. At the community level, the co-circulation of respiratory viruses is common and yet studies generally focus on single aetiologies. We conducted the first comprehensive epidemiological analysis to encompass all major respiratory viruses in a single population. Using extensive multiplex PCR diagnostic data generated by the largest NHS board in Scotland, we analysed 44230 patient episodes of respiratory illness that were simultaneously tested for 11 virus groups between 2005 and 2013, spanning the 2009 influenza A pandemic. We measured viral infection prevalence, described co-infections, and identified factors independently associated with viral infection using multivariable logistic regression. Our study provides baseline measures and reveals new insights that will direct future research into the epidemiological consequences of virus co-circulation. In particular, our study shows that (i) human coronavirus infections are more common during influenza seasons and in co-infections than previously recognized, (ii) factors associated with co-infection differ from those associated with viral infection overall, (iii) virus prevalence has increased over time especially in infants aged <1 year, and (iv) viral infection risk is greater in the post-2009 pandemic era, likely reflecting a widespread change in the viral population that warrants further investigation.

SUMMARYWe compared the rates of fever in adult subjects with laboratory-confirmed influenza and other respiratory viruses and examined the factors that predict fever in adults. Symptom data on 158 healthcare workers (HCWs) with a laboratory-confirmed respiratory virus infection were collected using standardized data collection forms from three separate studies. Overall, the rate of fever in confirmed viral respiratory infections in adult HCWs was 23·4% (37/158). Rates varied by virus: human rhinovirus (25·3%, 19/75), influenza A virus (30%, 3/10), coronavirus (28·6%, 2/7), human metapneumovirus (28·6%, 2/7), respiratory syncytial virus (14·3%, 4/28) and parainfluenza virus (8·3%, 1/12). Smoking [relative risk (RR) 4·65, 95% confidence interval (CI) 1·33–16·25] and co-infection with two or more viruses (RR 4·19, 95% CI 1·21–14·52) were significant predictors of fever. Fever is less common in adults with confirmed viral respiratory infections, including influenza, than described in children. More than 75% of adults with a viral respiratory infection do not have fever, which is an important finding for clinical triage of adult patients with respiratory infections. The accepted definition of ‘influenza-like illness’ includes fever and may be insensitive for surveillance when high case-finding is required. A more sensitive case definition could be used to identify adult cases, particularly in event of an emerging viral infection.

AbstractAcute respiratory infections cause significant morbidity and mortality accounting for 5.8 million deaths worldwide. In Australia, influenza-like illness (ILI), defined as cough, fever and fatigue is a common presentation in general practice and results in reduced productivity and lost working days. Little is known about the epidemiology of ILI in working-age adults. Using data from the ASPREN influenza surveillance network in Australia (2010–2013) we found that working-age adults made up 45.2% of all ILI notifications with 55% of samples positive for at least one respiratory virus. Viruses most commonly detected in our study included influenza A (20.6%), rhinovirus (18.6%), influenza B (6.2%), human meta-pneumovirus (3.4%), respiratory syncytial virus (3.1%), para-influenza virus (2.6%) and adenovirus (1.3%). We also demonstrated that influenza A is the predominant virus that increases ILI (by 1.2% per month for every positive influenza A case) in working-age adults during autumn–winter months while other viruses are active throughout the year. Understanding the epidemiology of viral respiratory infections through a year will help clinicians make informed decisions about testing, antibiotic and antiviral prescribing and when the beginning of the ‘flu season’ can be more confidently predicted.

Porcine reproductive and respiratory syndrome virus (PRRSV) is a major respiratory pathogen of swine that has become extremely costly to the swine industry worldwide, often causing losses in production and animal life due to their ease of spread. However, the intracellular changes that occur in pigs following viral respiratory infections are still scantily understood for PRRSV, as well as other viral respiratory infections. The aim of this study was to acquire a better understanding of the PRRS disease by comparing gene expression changes that occur in tracheobronchial lymph nodes (TBLN) of pigs infected with either porcine reproductive and respiratory syndrome virus (PRRSV), porcine circovirus type 2 (PCV-2), or swine influenza A virus (IAV-S) infections. The study identified and compared gene expression changes in the TBLN of 80 pigs following infection by PRRSV, PCV-2, IAV-S, or sham inoculation. Total RNA was pooled for each group and time-point (1, 3, 6, and 14 dpi) to make 16 libraries—analyses are by Digital Gene Expression Tag Profiling (DGETP). The data underwent standard filtering to generate a list of sequence tag raw counts that were then analyzed using multidimensional and differential expression statistical tests. The results showed that PRRSV, IAV-S and PCV-2 viral infections followed a clinical course in the pigs typical of experimental infection of young pigs with these viruses. Gene expression results echoed this course, as well as uncovered genes related to intersecting and unique host immune responses to the three viruses. By testing and observing the host response to other respiratory viruses, our study has elucidated similarities and differences that can assist in the development of vaccines and therapeutics that shorten or prevent a chronic PRRSV infection.
