Nowadays, the SARS Coronavirus 2 (SARS-CoV-2) infection is recognized as the primary cause of mortality in humans. SARS-CoV-2 is transmitted through human-to-human contact and is asymptomatic in mo...

According to the evidence, the coronavirus disease 19 (COVID‐19) is caused by a zoonotic pathogen named respiratory syndrome coronavirus 2 (SARS‐CoV‐2). This virus can spread through personal contact, respiratory droplets, and also through airborne transmission. A rapid, low‐cost, and effective biosensor platform is essential to diagnose patients with COVID‐19 infection, predominantly the asymptomatic individuals, and prevent the spread of the SARS‐CoV‐2 via transmission routes. The objective of this review is to provide a comparative view among current diagnostic methods, focusing on recently suggested biosensors for the detection of SARS‐CoV2 in clinical samples. A capable SARS‐CoV‐2 biosensor can be designed by the holistic insights of various biosensor studies.

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which has infected many people around the world. Children are considered an important target group for SARS-CoV-2, as well as other viral infections such as respiratory syncytial virus infection. Both SARS-CoV-2 and respiratory syncytial virus can affect the respiratory tract. Coinfection of SARS-CoV-2 and respiratory syncytial virus can pose significant challenges in terms of diagnosis and treatment in children. This review compares the symptoms, diagnostic methods, and treatment of COVID-19 and respiratory syncytial virus infection in children.

Crimean-Congo hemorrhagic fever is a tick-borne disease with high fatality rate that is endemic in some parts of Asia, Africa and Europe. Rapid diagnostics of Crimean-Congo hemorrhagic fever (CCHF) is necessary for appropriate clinical management of this disease and also can be useful in preventing of secondary spread from human-to-human, though, common tests which are used to diagnose Crimean-Congo hemorrhagic fever have some limitations. Here we review 1) common diagnostic tests for CCHF, 2) limitations in laboratories methods of CCHF and 3) biosensor researches for detection of CCHF. It is necessary to design and develop an effective, rapid, and also low-cost tool such as biosensor to detect Crimean-Congo hemorrhagic fever. Based on the key role of rapid detection of CCHF in the control of infection, development of a biosensor as a rapid tool seems very major in the diagnosis of CCHF, though, there are limited studies on this field and more researches are needed in this issue.
