nt for the disease. The virus has been renamed by WHO as SARS-CoV-2 and the disease caused by it as COVID-19. The disease since its first detection in China has now spread to over 200 countries/territories, with reports of local transmission happening in more than 160 of these countries/territories. As per WHO (as of 1st April, 2020), there has been a total of 823626 confirmed cases and 40598 deaths due to COVID-19 worldwide.
In India, as on 2nd April, 2020, 1965 confirmed cases (including 51 foreign nationals) and 50 deaths reported from 29 States/UTs. Large number of cases has been reported from Delhi, Karnataka, Kerala, Maharashtra, Rajasthan, Tamil Nadu, Telangana and Uttar Pradesh.

aboratory and clinical systems, according to capacity, availability of resources and cultural appropriateness. However, using a standardized protocol such as this one below, epidemiological exposure data and biological samples can be systematically collected and shared rapidly in a format that can be easily aggregated, tabulated and analyzed across many different settings globally for timely estimates of COVID-19 virus infection severity and attack rates, as well as to inform public health responses and policy decisions. This is particularly important in the context of a novel respiratory pathogen, such as COVID-19 virus

ica, en la que los macrófagos, los neutrófilos y las células dendríticas frenan el avance del virus y pueden incluso evitar que este provoque síntomas. A esta respuesta no específica le sigue una respuesta adaptativa en la que el organismo genera anticuerpos que se unen específicamente al virus. Estos anticuerpos son las proteínas denominadas inmunoglobulinas. El organismo también genera linfocitos T que reconocen y eliminan las células infectadas por el virus: es lo que se conoce como inmunidad celular. Esta respuesta adaptativa combinada puede eliminar el virus del organismo y, si la respuesta es suficientemente intensa, puede evitar el agravamiento de la enfermedad o la reinfección por el mismo virus. Este proceso se mide a menudo a través de la presencia de anticuerpos en la sangre.

aire innée, non spécifique, au cours de laquelle les macrophages, les neutrophiles et les cellules dendritiques ralentissent la progression du virus et peuvent même éviter l’apparition de symptômes. Cette réponse non spécifique est suivie d’une réponse adaptative, au cours de laquelle l’organisme produit des anticorps qui se lient spécifiquement au virus. Ces anticorps sont des protéines appelées immunoglobulines. L’organisme produit également des lymphocytes T qui reconnaissent et éliminent les cellules infectées par le virus. Cette réponse adaptative permet parfois d’éliminer le virus de l’organisme et, si elle est suffisamment forte, d’éviter l’aggravation de la maladie ou la réinfection par le même virus. Ce processus est souvent mesuré par la présence d’anticorps dans le sang.
