Background: The purpose of this review paper is to discuss the diagnostic and therapeutic value of lung ultrasonography in the context of coronavirus Disease 2019 (COVID-19). Ultrasound of the lungs is a straightforward diagnostic technique that helps find patients with symptoms that could be COVID-19 early on, which in turn helps with admission decisions and treatment planning. Not only may it be done in a variety of hospital wards, emergency rooms, primary care offices, and critical care units, but it can also be done in outpatient settings with the help of portable devices. In addition to clinical and laboratory evaluation, the article explains the usual findings on a COVID-19 lung ultrasonography, which include an interstitial pattern, pleural abnormalities, and consolidations. We outline the benefits and drawbacks of using lung ultrasonography in COVID-19, as well as the necessary equipment and training for this procedure. By searching the literature for the terms "COVID 19," "lung ultrasound," and "imaging," we were able to deduce the various regions' uses of this imaging technique. Children and pregnant women can benefit greatly from lung ultrasonography since it is a noninvasive, quick, and repeatable treatment that can be done at the point of care with minimal sterilization. since it uses non-ionizing radiation, it is possible to do multiple scans on the same patient. However, in the present pandemic environment, the patient and ultrasound operator cannot be physically close, which highlights the necessity for specific procedures to avoid and control infections. A big obstacle to the use of lung ultrasonography is the availability of competent personnel who are properly trained to do the procedure. In low- and middle-income countries, in particular, local practitioners can be better equipped to employ lung ultrasonography for COVID-19 management through training, advocacy, and increased awareness.
