Viral and bacterial infections in 20 children under 3 years of age were studied in a day centre for 12 weeks. Febrile illnesses were found on one occasion in each of 11 children but no serious infection occurred. Pneumococci types 6, 9, or 19 were isolated from all children but more often from those with rhinitis or cough. The individual child had an average of 2 viral infections. Adenovirus types 1, 2, 5, coxsackievirus type B5, herpes simplex virus or respiratory syncytial virus was isolated from 12% of the oropharynx swabs and 40% of the fecal specimens. When a virus was first isolated from the oropharynx, the children were asymptomatic or had only rhinitis in 73% of the cases which might indicate that the dismissing of symptomatic children is of limited value in controlling the spread of infections in a day care centre. Cytomegalovirus was recovered from 22% of the urine specimens. Carrier frequency of cytomegalovirus was 23% in 40 other children attending one of 13 different day care centers. Because asymptomatic cytomegalovirus infections apparently occur frequently among small children in Sweden, it seems reasonable not to take pronounced measures of isolating the children in the relatively few recognized cases of cytomegalovirus infections.

The clinical characteristics of acute otitis media in relation to coexisting respiratory virus infection were studied in a 1-year prospective study of 363 children with acute otitis media. Respiratory viruses were detected using virus isolation and virus antigen detection in nasopharyngeal specimens of 42% of the patients at the time of diagnosis. Rhinovirus (24%) and respiratory syncytial virus (13%) were the two most common viruses detected. Adenovirus, parainfluenza viruses, and coronavirus OC43 were found less frequently. The mean duration of preceding symptoms was 5.9 days before the diagnosis of acute otitis media. Ninety-four percent of the children had symptoms of upper respiratory tract infection. Fever was reported in 55% and earache in 47% of cases. Patients with respiratory syncytial virus infection had fever, cough, and vomiting significantly more often than patients with rhinovirus infection or virus-negative patients. No significant differences were found in the appearance of the tympanic membrane and outcome of illness between virus-negative and virus-positive patients with acute otitis. Most patients respond well to antimicrobial therapy despite the coexisting viral infection. If the symptoms of infection persist, they can be due to the underlying viral infection, and viral diagnostics preferably with rapid methods may be clinically useful in these patients.

Illness associated adenovirus infection is described in 15 immunocompromised patients. Patients were immunocompromised by severe underlying disease, immunosuppressive or corticosteroid therapy or by age (prematurity). Evidence of adenovirus infection was obtained by either viral isolation or, in two cases, characteristic adenovirus inclusion bodies at postmortem study. All clinical illness was associated with high fever (temperature greater than 39 degrees C). Eighty per cent of the patients had severe systemic complaints including malaise, lethargy, fatigue and night sweats; a similar number of gastrointestinal symptoms. Pulmonary complaints were described in 11 of 15 cases and included cough (67 per cent) and tachypnea (53 per cent). Roentgenologic evidence of pneumonia was demonstrated in 12 of 15 patients (80 per cent). Elevation of serum hepatic enzyme levels (serum glutamic pyruvic transaminase (SGPT)) occurred in eight of 11 patients (73 per cent) and was moderate to severe (serum glutamic pyruvic transaminase greater than 450 IU/liter) in five of 11 (45 per cent). Nine patients died; seven after a rapid downhill course and two after a prolonged illness. Evidence of adenovirus infection microscopically by autopsy in the lung, liver or both is demonstrated in four patients with fulminant systemic illness. Adenovirus infection should be considered in the etiology of severe overwhelming illness in the immunocompromised host.

Adenoviral pneumonia, while most common in infancy and young childhood, is rare in school childhood. Here, we report one case, a 13 years old otherwise healthy girl, suffered from fulminating pneumonia caused by adenovirus infection. She had dry cough, pharyngitis, lethargy, myalgia and fever in the beginning. Four days later, the patient became tachypneic, dyspneic and drowsy, and developed hypoxemia and diffuse bilateral infiltrates on chest radiographs. The laboratory data revealed elevated SGOT, CPK and LDH. Adenovirus was isolated from patient's endotracheal suction tube tips. Fortunately, weaning from mechanical ventilation was accomplished on the fifth day of hospitalization, despite of the high fatality rate of adenoviral pneumonia in this age group. The clinical characteristics and therapeutic management of our case are discussed and literatures reviewed.

This study retrospectively reviewed those pediatric patients of acute lower respiratory tract infection with positive virus identification by direct immunofluorescence assay (Direct IF) from Jan, 1992 to Dec, 1993. One hundred and eighteen patients with 133 positive Direct IF results (107 cases with single virus identified, and 11 cases with more than one) were included. The sex ratio was 1.6:1 with males predominant; age, 22.1 (1 approximately 154.8) (months); duration of admission, 5.7 (1 approximately 69) (days); peripheral white blood cell count, 10,600 +/- 3,800/mm3; C-reactive protein, 17.0 (0 approximately 163.3) mu/ml; body temperature, 37.1 +/- 1.1 degrees C in those cases with single virus. The symptoms were cough 105 cases (98.1%), rhinorrhea 46 cases (43.0%), dyspnea and/or tachypnea 43 cases (40.2%) and diarrhea 15 cases (14.0%). The viruses identified were: Adenovirus (52 cases, 39.1%). Influenza B (45 cases, 33.8%), Parainfluenza 1 (28 cases, 20.1%), Parainfluenza 3 (19 cases 14.3%), Respiratory Syncytial virus (17 cases, 12.8%), and Influenza A (9 cases, 6.8%). The seasonal incidence rates were spring (49 cases, 36.8%), summer (46 cases, 34.6%), autumn (23 cases, 17.3%), and winter (15 cases, 11.3%). The results showed much similarity with others, except the commonest viral type (Adenovirus in this study; Respiratory Syncytial virus in others) and the seasonal incidence rate (higher in spring and summer in this study but not in others). In conclusion, most children with acute viral lower respiratory tract infection had an uneventful course and Direct IF is a reliable method for viral detection in that disease.

We have encountered a 12-year-old girl with acute respiratory disease including pneumonia caused by adenovirus type 7. While being followed-up for bronchial asthma, she developed this disease with dyspnea accompanied by high fever, pharyngalgia and a dry cough subsequent to a slight fever. Adenovirus type 7 was separated and identified from the pharyngeal smear. Additionally, perfusion scintigraphy of the lungs presented evidence of interstitial pneumonia. with these findings and the clinical course put together, this case was diagnosed as having acute respiratory disease with pneumonia caused by adenovirus type 7. Thereafter, perfusion scintigraphy of the lungs continued showing interstitial shadows, which suggested the presence of severe sequlae of the lung. Formerly the separation rate of adenovirus type 7 was low in Japan, but the rate has tended to increase in cities in recent years. Cases presenting such acute, severe respiratory symptoms are expected to increase in the future, and clinically we consider to be our case important enough to be reported.

Eighteen cases of pneumonia developed during an outbreak of adenovirus infection in a chronic psychiatric care facility. The six patients most severely affected were admitted to the intensive care unit (ICU) at our institution. Four of these patients developed septic shock. We report the presentation, disease progression, and response to treatment of these patients. Clinical features consisted of high fever, nonproductive cough, and dense lower lobe infiltrates. Laboratory abnormalities included transient fall in white blood cell and platelet counts, and elevations of transaminases, lactate dehydrogenase (LDH), and creatinine phosphokinase (CPK). Five patients were intubated for hypoxemia and four developed the acute respiratory distress syndrome (ARDS) and septic shock (mean cardiac output, 14.1 +/- 1.3 L/min; cardiac index, 6.4 +/- 0.4 L/min/min2; systemic vascular resistance, 326 +/- 107 dyne cm/s2). All patients recovered and were discharged back to the chronic care facility except for one patient with chronic renal failure who died 2 mo after admission. Adenovirus (serotype 35) was isolated from the respiratory secretions of five patients and antibody titers increased 6-fold in the other. These patients constitute the largest series of patients with ARDS and septic shock caused by adenovirus pneumonia and the first outbreak of multiple cases of adenovirus pneumonia in immunocompetent civilian adults occurring from a single source.

This study clinically and molecularly characterizes an adenovirus epidemic that broke out in Taiwan in April 2004. Clinical data on 325 children diagnosed with acute illness were collected between April 2004 and April 2005, and a diagnosis of adenovirus was confirmed by viral isolation. Polymerase chain reaction and restriction fragment length polymorphism were used to identify the adenovirus genotypes in 267 patients. There was a seasonal variation, with a peak incidence between November 2004 and January 2005 (p < 0.001). The median age was 52 months, range 1-210 months. Most cases (90.8%) were younger than 7 years old. Male-to-female ratio was 1.56:1. The most common clinical diagnosis was exudative tonsillitis (50.8%), followed by bronchitis/bronchiolitis (29.9%), conjunctivitis or pharyngoconjunctival fever (22.5%), and acute otitis media (16.3%). Adenovirus type 3 was found in 215 patients (80.5%). The other 52 patients had other genotypes: type 2 (10.1%), type 1 (6.0%), type 5 (1.9%), type 7 (0.7%), type 4 (0.4%), and type 6 (0.4%). Patients with type 3 were significantly older [age >52 months, adjusted odds ratio (OR) 8.55, 95% confidence interval (CI) 1.84-40, p = 0.006), their family members had a higher incidence of illness (adjusted OR 8.77, 95% CI 1.55-50, p = 0.01), they coughed (adjusted OR 6.37, 95% CI 1.54-26.3, p = 0.01), and they had a higher C-reactive protein (CRP) level (>2.87 mg/dL, adjusted OR 3.64, 95% CI 1.06-12.3, p = 0.04) than the 52 cases with other genotypes. In conclusion, this adenovirus outbreak, from late autumn to winter, was predominately caused by adenovirus type 3. Patients with this genotype were significantly older, had a higher incidence of cough and family transmission, and had higher CRP levels than those with other genotypes.

Adenovirus serotypes 4 (ADV-4) and 7 (ADV-7) are important causes of febrile acute respiratory disease (ARD) in US military recruits. Previously licensed vaccines, which effectively controlled adenovirus-associated ARD, are no longer available. In the Fall of 2004 we conducted this Phase 1 randomized, double-blind, placebo-controlled trial of the live, oral ADV-4 and ADV-7 vaccines made by a new manufacturer to assess their safety and immunogenicity. The adenovirus vaccines were administered orally together in a single dose to thirty subjects. Twenty eight additional subjects received placebo. Subjects were then observed for 8 weeks. The most commonly reported adverse events were nasal congestion (33%), cough (33%), sore throat (27%), headache (20%), abdominal pain (17%), arthralgia (13%), nausea (13%) and diarrhea (13%). None of these rates differed significantly from placebo. The duration of vaccine virus fecal shedding was 7-21 days. Seventy three percent of vaccine recipients seroconverted to ADV-4 (GMT 23.3) while 63% seroconverted to ADV-7 (GMT 51.1) by Day 28. The new ADV-4 and ADV-7 vaccines were safe and induced a good immune response in the study population. Expanded trials for safety and efficacy are in progress.

Sequences of epidemic waves have been observed in past influenza pandemics, such as the Spanish influenza. Possible explanations may be sought either in mechanisms altering the structure of the network of contacts, such as those induced by changes in the rates of movement of people or by public health measures, or in the genetic drift of the influenza virus, since the appearance of new strains can reduce or eliminate herd immunity. The pandemic outbreaks may also be influenced by coinfection with other acute respiratory infections (ARI) that increase transmissibility of influenza virus (by coughing, sneezing, running nose). In fact, some viruses (e.g., Rhinovirus and Adenovirus) have been found to induce "clouds" of bacteria and increase the transmissibility of Staphylococcus aureus. Moreover, Rhinovirus and Adenovirus were detected in patients during past pandemics, and their presence is linked to superspreading events. In this paper, by assuming increased transmissibility in coinfected individuals, we propose and study a model where multiple pandemic waves are triggered by coinfection with ARI. The model agrees well with mortality excess data during the 1918 pandemic influenza, thereby providing indications for potential pandemic mitigation.
