  • ADENOVIRUS Adenoviruses Are Common Viruses That Typically Cause Mild Cold- Or Flu-Like Illness
    ADENOVIRUS Adenoviruses are common viruses that typically cause mild cold- or flu-like illness. Adenoviruses can cause illness in people of all ages any time of year. ADENOVIRUS Adenoviruses can cause a wide range of illnesses including • common cold- or flu-like symptoms SYMPTOMS • fever • sore throat • pink eye (conjunctivitis) • acute bronchitis (inflammation of the airways of the lungs, sometimes called a “chest cold”) • pneumonia (infection of the lungs, occasionally severe) • diarrhea • acute gastroenteritis (inflammation of the stomach or intestines causing diarrhea, vomiting, nausea, and stomach pain) Less common illnesses caused by adenovirus include bladder infection or inflammation and neurologic disease (conditions that affect the brain and spinal cord). HOW Adenoviruses are usually spread from an infected person to others through ADENOVIRUSES • close personal contact, such as touching or shaking hands SPREAD • the air by coughing and sneezing • touching an object or surface with adenoviruses on it, then touching your mouth, nose, or eyes before washing your hands • contact with stool, for example, during diaper changing Adenoviruses are often resistant to common disinfectants and can remain infectious for long periods of time on surfaces and objects. WHO IS AT RISK FOR SEVERE ADENOVIRUS INFECTION? People with weakened immune systems (including from medications they are taking or from heart or lung diseases) are at higher risk for developing severe adenovirus infection. Certain types of this virus have been linked to more severe illness. Rarely, otherwise healthy people with adenovirus infections will become so ill that they need to be hospitalized and may die.

Despite this, diagnostic testing for specific viruses underlying ILI is relatively rare (CDC 2019). This results in a lack of information about the pathogens that make between 9 million and 49 million people sick every year in the United States alone (CDC 2020). Yet knowledge of the specific diseases is necessary for timely treatment to prevent unnecessary suffering and death (Nguyen 2016, Van Asten et al. 2012, Pawelek et al. 2015). ◦ ILI is defined by the CDC as fever of 100 F and a cough and/or a sore throat without a known cause other than influenza (CDC 2020). Defining ILI as a cluster of symptoms rather than a specific disease or diseases is necessary for keeping track of case counts, as well as for important analysis and forecasting (Osthus and Moran 2019).

Choi Division of Allergy and Infectious Diseases, Department of Medicine, University of Washington, Seattle, USA. Email: [email protected] Received September 12th, 2012; revised October 29th, 2012; accepted November 10th, 2012 ABSTRACT Introduction: Adenovirus infections are associated with significant morbidity and mortality among immunocompro- mised hosts. Adenovirus pneumonia is a rare and often fatal disease in patients with AIDS. Case Report: We report a case of a 28-year-old woman with advanced HIV/AIDS, who developed pneumonia four weeks after initiation of highly active antiretroviral therapy (HAART). Despite empiric antibiotics, the patient developed worsening hypoxemia and progressive pneumonia on chest x-ray. Culture data from a bronchoalveolar lavage (BAL) was negative for bacteria, fungi, pneumocystis jirovecii, but was positive for adenovirus detected by PCR. After transfer to a tertiary care hospital intensive care unit, a repeat BAL confirmed the presence of adenovirus by immunohistochemical staining. Tissue sam- ples sent for histopathology revealed “smudge cells”. Serum adenovirus viral load was 1.6 × 105 copies/mL. Intrave- nous cidofovir, 1 mg/kg/day, was initiated and scheduled three times a week. The patient exhibited remarkable im- provement and was discharged to home in stable condition after four doses of cidofovir treatment. Discussion: Prior to our case, the few published accounts of HIV patients with adenovirus pneumonia treated with cidofovir have all re- sulted in death.

There are four genera: Mastadenovirus, Aviadenovirus, Atadenovirus and Siadenovirus. At present 51 antigenic types of human adenoviruses have been described. Human adenoviruses have been classified into six groups (A–F) on the basis of their physical, chemical and biological properties (WHO 2004). Reservoir Humans. Adenoviruses are ubiquitous in the environment where contamination by human faeces or sewage has occurred. Distribution Adenoviruses have worldwide distribution. Characteristics An important feature of the adenovirus is that it has a DNA rather than an RNA genome. Portions of this viral DNA persist in host cells after viral replication has stopped as either a circular extra chromosome or by integration into the host DNA (Hogg 2000). This persistence may be important in the pathogenesis of the known sequelae of adenoviral infection that include Swyer-James syndrome, permanent airways obstruction, bronchiectasis, bronchiolitis obliterans, and steroid-resistant asthma (Becroft 1971; Tan et al.

  • Adenovirus Infection in Families
    Archives of Disease in Childhood, 1988, 63, 1250-1253 Adenovirus infection in families O RUUSKANEN, J MERTSOLA, AND 0 MEURMAN* Departments of Paediatrics and *Virology, University of Turku, Finland SUMMARY Eighteen families were followed up for four to six weeks after one member of each family was diagnosed as having an adenovirus infection. In 17 of 18 index cases the diagnosis was based on the rapid detection of adenovirus hexon antigen in the nasopharyngeal mucus specimens and in one case (the only adult index case) on isolation of the virus. All index cases had high temperatures associated most commonly with tonsillitis, acute otitis media, gastroenteritis, or febrile convulsions. In 14 of the 16 families with symptomatic contacts the index case was the first symptomatic case, or one of the first symptomatic cases, in that family. Fifteen (94%) of the siblings and 20 (56%) of the parents had signs and symptoms of acute infection during the follow up period. In 10 (63%) and eight (20%) of these cases, respectively, adenovirus was confirmed. The mean (SD) incubation period of confirmed adenovirus infections was 10 (3) days. The observations show that adenovirus infection spreads actively to other siblings in the family. Rapid diagnosis permits parents to be informed prospectively about the expected spread and clinical picture of the illness in the family.

  • Respiratory Illness and Viral Infection in an Edinburgh Nursery by C
    J. Hyg., Camb. (1967), 65, 25 25 Printed in Oreat Britain Respiratory illness and viral infection in an Edinburgh nursery BY C. J. D. AITKEN,* MARGARET A. J. MOFFAT AND J. A. W. SUTHERLAND Wellcome Laboratory, City Hospital, Edinburgh (Received 19 September 1966) In recent years many outbreaks of respiratory syncytial virus infection have been reported and the associated clinical syndromes are now well documented (Chanock et al. 1962; Hilleman et al. 1962; Holzel et al. 1965). Similarly many accounts of respiratory illness resulting from infection with adenovirus (Bell et al. 1955; Chany et al. 1958; Hilleman et al. 1962), parainfluenza virus (Hilleman et al. 1962; Parrott, Vargosko, Kim & Chanock, 1963) and influenza virus (Balducci, Zaiman & Tyrrell, 1956; Holland, Tanner, Pereira & Taylor, 1960) have been published. However, few investigations on these or other respiratory virus in- fections have been carried out on static populations of normal subjects who were undergoing continuous clinical observation. In this country, Sutton (1962) reported outbreaks of influenza A, parainfluenza 3 and adenovirus infections occurring over a period of 8 months in a nursery containing forty-six children. In the U.S.A., Bell, Rowe & Rosen (1962) described the illnesses occurring in 587 children of the Washington Children's Village over a period of 3 years and described outbreaks of infection with adenoviruses, myxoviruses and coxsackie- viruses. Kapikian et al. (1961) extensively documented an outbreak of respiratory syncytial virus infection in the Washington Children's Village among ninety children who were under continuous clinical observation. The present survey was carried out in a community of resident nursery children in Edinburgh during the winter 1963-64 to investigate the prevalence and type of virus infection, as proved by serological means, and to relate this to the respiratory illnesses occurring at the time.

  • Adenovirus Is a Type of Virus That Most Commonly Infects the Upper Respiratory Tract, Causing Cold-Like Symptoms, Pink-Eye (Conjunctivitis) Or Rash Illnesses
    Rick Scott : Mission Governor To protect, promote & improve the health of all people in Florida through integrated John H. Armstrong, MD, FACS state, county & community efforts. State Surgeon General & Secretary Vision: To be the Healthiest State in the Nation ADENOVIRUS Accompanying: Hand Washing Fact Sheet What is Adenovirus? Adenovirus is a type of virus that most commonly infects the upper respiratory tract, causing cold-like symptoms, pink-eye (conjunctivitis) or rash illnesses. However, a few adenovirus serotypes can also cause gastrointestinal illness. What are the signs and symptoms of an Adenovirus infection? Adenovirus respiratory infection may include headache, fever, runny-nose, sore throat, and red-watery eyes. The gastroenteritis form of the virus will present as nausea, vomiting, and diarrhea. How are Adenovirus infections spread? Adenoviruses causing respiratory tract infection are spread through person to person contact (breathing in the virus). The gastroenteritis form of the virus is most often contracted through poor hand washing after an infected person has a bowel movement or by touching objects that have the virus on it. What is the incubation period of Adenovirus and how long is it contagious? The incubation period for respiratory infection varies from 2 to 14 days, however, for gastroenteritis it is 3 to 10 days. Adenovirus infections are most communicable during the first few days of acute illness, but persistent and intermittent shedding of the virus for longer periods is frequent and reinfection can occur. What should I do if I think I have an Adenovirus infection? Children who have these symptoms should see their pediatricians. Children cannot attend daycare.
