COVID-19 is a contagious infection caused by the coronavirus family, the most recently revealed disease. This newly discovered virus has been provisionally termed “2019 novel Coronavirus” (2019-nCoV), which is a novel infection outbreak with possibly extensive public health complications, therefore on the edge of spreading throughout the world.
Signs associated with novel Coronavirus:
The indications associated with thisCOVID-19, include high temperature, drowsiness, and dry cough. A number of sufferers might possess pains and aches, sore throat, nasal jamming, runny nose or diarrhea. All of these mentioned symptoms are generally minor and initiate progressively.
For the above-mentioned reasons, vaccines for this virus cannot be rapidly prepared for at least a year to the public. Therefore, the best thing is to check symptomatic patients to avoid or slow the virus spread.
Screening methods:
Presently, polymerase chain reaction (PCR), a molecular technique necessitating distinct laboratory machines, is used to diagnose maximum pandemic-prone diseases, including coronavirus. The diagnosis of Coronavirus is taking a new turn as the current nucleic acid testing protocols are turning up a high amount of false negative. For better disease treatment and control, early identification of the virus COVID-19 is crucial.
Computed tomography:
Computed tomography(CT), a routine imaging tool, is fast and comparatively stress-free to perform. CT usage distinct x-ray equipment to inspect irregularities found in other imaging tests and to aid diagnoses the reason of unexplained cough, breathing shortness, chest pain, and fever. The advantages of CT scanning are accuracy; speed, simple, as well as noninvasive.
Compared to RT-PCR, chest CT imaging is considered for better stable, applied, and fast method to diagnose and assess COVID-19, especially in the epidemic area. In numerous studies, the sensitivity of chest CT was found to be greater (98 percent) than that of RT-PCR.
A number of researches trust the usage of chest CT for COVD-19 diagnosis for patients with medical and epidemiologic symptoms well-matched with COVID-19 contagion principally when RT-PCR test is negative. Hence, now the focus of the scientific world should be on testing the suspected patients at the initial stage and quarantine the infected as soon as possible. This action will not only help to reduce the current Covid-19 epidemic greatly but also will generate a system for emerging comparable tools to end upcoming pandemics.
