Commentary tients were referred to COVID-19 facility, but all of them were asked to exercise extreme caution and were only given telephonic consultations. All 55 "No and Low risk" cases recovered clinically, they were found to be asymptomatic 7 days after consultation. Based on clinical judgement, all these cases were considered true negatives and not asymptomatic carriers. Hence, ORTIS system showed a 100% Negative Predictive Value.
ORTIS has been designed for implementation in ongoing and any future viral outbreaks with respiratory failure or pneumonia as possible complications. The ORTIS System can be performed telephonically which is critical in bifurcating the suspected patients towards COVID-19 dedicated hospitals during the early stages of clinical presentation. This step is crucial in reducing the risk of nosocomial transmission, infection transmission to the community and to the healthcare workers. "No risk" children are typically patients with straightforward diagnosis such as UTI or Neonatal Septicemia. "Low risk" children can be assumed to have an unlikely risk of COVID-19 infection, "Medium risk" children should be carefully evaluated and a follow up evaluation is a must. "High risk" cases should be urgently referred to dedicated centres for outbreak disease. The pilot study has important limitations such as low sample size and study participants not tested for SARS-CoV-2 infection by PCR analysis for microbiological confirmation. Although inter observer variation was not assessed, the objective and history based construct of scoring minimizes chances of any variations.
Since December 2019, over two million people worldwide have been affected by coronavirus disease 2019 (COVID-19). Because of quarantine measures, overcrowded healthcare facilities, fear of contracting the disease and forced behavioural modification to suspect every respiratory tract infection as a potential COVID-19 case -parents of sick children are hesitant to contact healthcare facilities in developing countries such as India. Acute shortage of specialist care has led to increased suffering of children affected by other diseases. Such patients are being continuously received in critical state due to a delay in contact. In resource scarce settings with an incomplete understanding of the disease process, there is also a lack of confidence amongst pediatricians while screening the patients for COVID-19 clinically. This problem has compounded due to infected doctors and staff who constitute the first and only line of defence against the pandemic, leading to sub-optimal levels of functioning of many healthcare facilities.
Haiyan Qiu and colleagues elaborated little known clinical and epidemiological details of COVID-19 in pediatric population [1]. To help pediatricians clinically screen the patients of COVID-19 and comfortably deal with patient families with unlikely coronavirus infection, a scoring system called "Outbreak of Respiratory Tract Infection Score" or ORTIS System has been devised ( Table 1). ORTIS was conceptualized based on expert opinion and review of literature of past outbreaks of viral infections in children with predominant respiratory system involvement [1][2][3][4][5]. The primary purpose of the scale is to confidently rule out the chances of CoVID-19 infection.
