SARS-CoV- 2 is the causative agent of the global pandemic, also known as Covid-19. This virus belongs to a group of coronaviruses and has affected more than ten million people across the globe, causing nearly half a million deaths worldwide. The pandemic has spread worldwide, originating in the Wuhan Hubei province of China in 2019. The disease is a significant challenge as there is no antiviral treatment. This review will address current trends and emerging new methods for detecting SARS-CoV-2 in the laboratoryat present. Reverse transcriptase PCR or RT-PCR is the gold standard for detecting SARS-CoV-2 disease. The seroprevalence of Covid-19 is performed using antibody detection tests using ELISA and antigen detection as rapid tests. In clinical practice, preliminary disease identification is made based on Chest radiographs, computed tomography, and positron emission tomography (PET) scans. As the pandemic has progressed, newer methods of detection like CRISPR, nanotechnology-enabled solutions, and biosensors have emerged as new methods of detecting SARS-CoV-2.

Tuberculosis is a contagious infectious disease. This disease is called tuberculosis and is abbreviated as TB. Tuberculosis is one of the most important infectious diseases of this century, which can involve all the organs of the body, but the lungs are most affected by tuberculosis. The occurrence of 10 million new cases of tuberculosis and the treatment of only two-thirds of them, which unfortunately was incomplete in more than 50% of cases, shows the depth of the disaster in these years. The occurrence of three epidemics of this disease in the last two decades shows that the prospect of controlling tuberculosis soon is very uncertain. Today, more than 8 million people are infected with this disease in the world every year, and until now, one-third of the world's people have been infected with the germ of tuberculosis without feeling sick. Tuberculous peritonitis is an uncommon disorder; sometimes, it is not considered in the initial evaluation of ascites. A negative 5-TU PPD test, or a low level of ascitic fluid protein, can mistakenly divert attention from tuberculosis. Tuberculosis peritonitis can be fatal if not diagnosed in time. Here we report a 67-year-old patient who was confirmed to have tuberculous peritonitis after clinical examination and laboratory diagnosis. The patient recovered after diagnosis with prescribed drugs.
