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.

People with viral pneumonia need to stay hydrated and rest to help the body heal.
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%).
Unless oseltamivir is given very early in the virus amplification stage, it cannot prevent or cure the viral pneumonia or ARDS directly due to the virus virulence and inflammatory and innate immune responses.
Viral pneumonia generally does not produce exudative fluids unless there is a superinfection with a secondary bacterial pneumonia.
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.
The three main health threats from influenza are (1) viral pneumonia or secondary bacterial pneumonia and death in susceptible people, (2) epidemics, and (3) less frequent but more deadly and widespread pandemics.
Other general topics include diagnostic techniques including radiology and function testing, special problems such as pleural infusion, pneumothorax, hemoptysis, aspiration pneumonia, and the lung in pregnancy, hyperbaric oxygen therapy, a range of pulmonary infections including tuberculosis, emphysema, viral pneumonia, infections complicated by HIV and hospital-acquired pneumonia, airways diseases, acute respiratory failure, cardiovascular and thromboembolic disease, congenital and pediatric lung diseases including cystic fibrosis, chest wall and neuromuscular disorders, environmental and occupational diseases, idiopathic, immunologic and granulomatous disease, and neoplastic diseases.
This is what makes the cases worrisome and something physicians everywhere should be familiar with, even though the chances of seeing a case at present are extremely low and a physician encountering such a patient would likely recognize right away that he or she was not dealing with bronchitis or viral pneumonia, Dr.
Victims of the disease develop fever, sore throats, coughs and, in serious cases, severe respiratory distress and viral pneumonia which can be fatal.
We compared serum LBP concentrations in patients with pneumonia caused by atypical pathogens with those found in the rest of the patients with pneumonia; we also compared them specifically with the concentrations in patients diagnosed as having bacterial pneumonia, viral pneumonia, or pneumonia of unknown etiology.
Infection with influenza presents as a spectrum of disease ranging from patients who are asymptomatic to those with fulminant primary viral pneumonia, depending on host immune status and the dose of virus.
