An initial study suggests that more than 80%of individuals aged 20 and under may show no symptoms after contracting SARS-CoV-2. This may have important implications for infection transmission.
Experts from the Bruno Kessler Foundation in Trento, Italy, in collaboration with colleagues associated to the ATS Lombardy COVID-19 Task Force and different research institutions, carried out a study examining what portion of individuals who have actually contracted SARS– CoV-2 are likely to experience any signs.
This preliminary research study does not yet appear in a peer-reviewed journal, however its authors have actually made their findings readily available online, on the preprint platform arXiv
The rate of likely asymptomatic carriers of the coronavirus could have important ramifications for viral transmission, the research study authors mention.

” This work enables us to plainly show the difficulties in determining infections with monitoring given that most of these are not connected with breathing symptoms or fever,” states study co-author Stefano Merler, who focuses on mathematical modeling of transmittable illness transmission.
The scientists analyzed information on 5,484 individuals from the Lombardy region of Italy who had actually been in contact with people with a new coronavirus infection. Of these, 2,824 individuals had laboratory-confirmed SARS-CoV-2 infections.
Taking a look at the information, the private investigators found that, of the 2,824 individuals with known coronavirus infections, just 876 (31%) had actually presented any signs.
