viral pneumonia

pulmonary infection caused by a virus.

viral pneumonia

Pulmonology Pneumonia of viral origin, which is more severe in the very young and very old Common pathogens Adenovirus, influenza virus, parainfluenza virus, RSV, rhinovirus, HS, CMV. See Influenza, Pneumonia, Respiratory syncytial virus.

viral pneumonia

Any infections of the lower respiratory tract (the lungs, bronchioles, and trachea) caused by viral species such as adenovirus, coronavirus, herpesviruses, influenza viruses, and respiratory syncytial viruses. Viral pneumonias may range from mild respiratory infections (with nonproductive cough and low-grade fevers) to life-threatening and highly contagious illnesses (such as SARS). See: bronchitis; bronchiolitis

viral

pertaining to or caused by a virus.

viral abortion
see equine viral abortion (below). See also equine viral rhinopneumonitis, equine viral arteritis, infectious bovine rhinotracheitis.
viral arteritis
see equine viral arteritis.
viral arthritis
a contagious disease of chickens and turkeys caused by a reovirus and characterized by a high incidence of inapparent infection and some cases of joint swelling and lameness.
viral assembly
final steps in the replication of viruses in which virions are assembled from their separately synthesized components. The final steps of viral maturation prior to release from the cell.
viral cultivation
viruses grow only in living cells which in the laboratory are provided by embryonated hen eggs, cell culture, or laboratory animals (rabbits, mice, etc.).
viral diarrhea
occurs in most species, especially in the newborn. In cattle, rotavirus and coronavirus are the common agents but bovine herpesvirus 1 and others may also be the cause in this age group. In older cattle bovine virus diarrhea (mucosal disease) is the major cause. Some other diseases may have diarrhea as an incidental sign, e.g. rinderpest, bovine malignant catarrhal fever.
equine viral abortion
caused by equine herpesvirus 1, sometimes equine herpesvirus 4. Abortion occurs in the last trimester and often involves a majority of mares in a group (abortion storm). See also equine viral rhinopneumonitis, equine viral arteritis.
viral hemorrhagic septicemia
important rhabdoviral infection of rainbow trout. Also causes infection, and sometimes disease, in other salmonids, pike, turbot, Pacific cod and Pacific herring. Acute infection is characterized by hemorrhages and a high mortality. Chronic infection may be inapparent.
viral hepatitis
see duck hepatitis.
viral interstitial pneumonia
bovine syncytial virus, a common cause of interstitial pneumonia in all age cattle, especially calves.
viral ligand
a receptor binding molecule on the surface of a virus. See also ligand.
viral papular dermatitis
see equine papular dermatitis.
viral pneumonia
see enzootic pneumonia.
viral pneumonia calf
caused by parainfluenza-3 virus, bovine respiratory syncytial virus; infection with Mycoplasma, Ureaplasma, Pasteurella spp. may also accompany the viral infection.
viral recombination
viral replication
viral teratogen
see akabane virus disease, aino virus disease, bovine virus diarrhea, rift valley fever, wesselsbron disease, bluetongue, border disease, classical swine fever (hog cholera), feline panleukopenia.

In clinical practice, we should follow the correct diagnostic method and strengthen differential diagnosis from pulmonary tuberculosis, fungal infection, viral pneumonia, interstitial pneumonia, heart failure and so on.
It is against this background that WHO defined pneumonia was revisited by this study to refine the parameters in order to filter out allergic airway disease and viral pneumonia.
Major findings include (1) tracheitis and/or bronchitis in all cases, with DAD-associated viral pneumonia as the primary pathology; (2) distribution of influenza viral antigen predominantly in the tracheobronchial epithelium and submucosal glands, and to a lesser extent in bronchiolar epithelium and alveolar epithelial cells and macrophages; (3) bacterial pneumonia in 55%; and (4) comorbidities in 91% of adult and adolescent decedents (with obesity in 72%).
The viral pneumonia or acute respiratory distress syndrome (ARDS) of influenza has a major causative contribution from this cytokine storm.
He was killed by a blood clot on the lungs and also suffered from heart disease and had high blood pressure as well as viral pneumonia.
He also suffered from heart disease and high blood pressure, and had viral pneumonia.
Persons for whom antiviral treatment should be considered include those with influenza viral pneumonia or influenza and complicating bacterial pneumonia.
Viral pneumonia generally does not produce exudative fluids unless there is a superinfection with a secondary bacterial pneumonia.
Examples include viral pneumonia, opportunistic infections in HIV patients, atypical infections such as mycoplasm, congestive heart failure, and pulmonary embolus.
Symptoms vary depending on the type of infection, with viral pneumonia often imitating flu symptoms, while bacterial pneumonia tends to come on suddenly and involve severe chest pain, fever, mucus-producing cough and increased breathing rate.
