    en.wikipedia.org/wiki/Ground-glass_opacity

    Ground-glass opacity is among the most common imaging findings in patients with confirmed COVID-19. [16] [17] One systematic review found that among patients with COVID-19 and abnormal lung findings on CT, greater than 80% had GGOs, with greater than 50% having mixed GGOs and consolidation. [16]

    Half of coronavirus-positives there who remained mild or asymptomatic had pneumonia findings on CT scans and their CT image showed a frosted glass shadow that is characteristic of infection. [214] [216] As of 18 July, Japan's daily PCR testing capacity was about 32,000, more than three times the 10,000 cases as of April.

    CT scans are considerably more expensive than nucleic acid tests and involve a small dose of radiation. For COVID-19, they are seen as the most accurate diagnostic tool, because the disease creates patchy "ground glass" areas in the lungs that are revealed by a scan. One study found 97% sensitivity. [14]

    SARS-CoV-2. Analysis of COVID-19 CT imaging along with postmortem lung biopsies and autopsies suggest that the majority of patients with COVID-19 pulmonary involvement also have secondary organizing pneumonia (OP) or its histological variant, acute fibrinous and organizing pneumonia, which are both well-known complications of viral infections. [15]

    Electrocardiogram findings were variable and ranged from sinus tachycardia, ST-segment elevation, T-wave inversion and ST-depression. [48] In one case, viral particles were seen in the interstitial cell, and another case reported SARS-CoV-2 RT–PCR positivity in the cardiac tissue suggestive of direct viral injury to the myocardium.

    On 11 February 2020, the International Committee on Taxonomy of Viruses adopted the official name "severe acute respiratory syndrome coronavirus 2" (SARS‑CoV‑2). [33] To avoid confusion with the disease SARS , the WHO sometimes refers to SARS‑CoV‑2 as "the COVID-19 virus" in public health communications [ 34 ] [ 35 ] and the name HCoV ...

  8. Viral pneumonia - Wikipedia

    en.wikipedia.org/wiki/Viral_pneumonia

    Viral pneumonia is a pneumonia caused by a virus. Pneumonia is an infection that causes inflammation in one or both lungs. Pneumonia is an infection that causes inflammation in one or both lungs. The pulmonary alveoli fill with fluid or pus making it difficult to breathe. [ 1 ]

  9. Pneumonia - Wikipedia

    en.wikipedia.org/wiki/Pneumonia

    Radiographs of viral pneumonia may appear normal, appear hyper-inflated, have bilateral patchy areas, or present similar to bacterial pneumonia with lobar consolidation. [42] Radiologic findings may not be present in the early stages of the disease, especially in the presence of dehydration, or may be difficult to interpret in the obese or ...
