Public health implications of transmissions of COVID-19 while cases
asymptomatic: a literature review
Abstract
Corona Virus Disease 2019 is an RNA virus that currently affecting more
than 210 countries, more than 3,221,617 cases, and 228,263 deaths are
reported till April 28, 2020. There is a knowledge gap regarding the
incidence proportion of asymptomatic and symptomatic infection so that
public health interventions can be reviewed. We searched the original
articles in google Scholar for articles that were published from January
1 through May 5 2020, and country updated reports of coronavirus
disease. Finally, reviewed to compile and make conclusions. Different
epidemiologic studies support the possibility of severe acute
respiratory syndrome coronavirus 2 (SARS-CoV-2) detected could able to
transmit during the asymptomatic state. SARS-CoV-2 transmission in the
absence of symptoms reinforces the value of measures that prevent the
spread of SARS-CoV-2 by infected persons who may not exhibit illness
despite being infectious. The existence of persons with asymptomatic
SARS-CoV-2 infection who are capable of transmitting had many
implications. The case-fatality rate for COVID-19 may be lower or
inaccurate, reinforces the value of community interventions, and could
enhance the need to increase the capacity for widespread testing and
thorough contact tracing.
