STUDY: ASYMPTOMATIC COVID-19 NON CONTAGIOUS

We publish a study just released in which it ends that the infectivity of some asymptomatic carriers of SARS-CoV-2 "could be weak". In practice they followed all contacts (455) of a positive Covid-19 asymptomatic and found that none had been infected. It is legitimate to ask more than a few questions in a historical moment in which citizenship (even pediatric) is forced to wear masks even outdoors and where they are trying to convince us that "social distancing" is necessary to protect ourselves and others.


ABSTRACT

Background: An ongoing coronavirus outbreak in 2019 (COVID-19) has spread worldwide. It is questionable whether carriers of asymptomatic COVID-19 viruses are contagious. Here we report a case of the asymptomatic patient and present the clinical characteristics of 455 contacts, which aims to study the infectivity of asymptomatic carriers.

Material and methods: 455 contacts that were exposed to the carrier of the asymptomatic virus COVID-19 became the subjects of our research. They were divided into three groups: 35 patients, 196 family members and 224 hospital staff. We extracted epidemiological information, clinical records, auxiliary test results and therapeutic programs.

Results: the average contact time for patients was four days and that for family members was five days. Cardiovascular disease accounted for 25% of the patients' original diseases. In addition to the hospital staff, both patients and family members were medically isolated. During the quarantine, seven patients plus one family member experienced new respiratory symptoms, where fever was the most frequent. The blood count in most contacts was within a normal range. All CT images showed no signs of COVID-19 infection. No coronavirus 2 (SARS-CoV-2) infection was detected for severe acute respiratory syndrome in 455 contacts by nucleic acid test.

Conclusion: in summary, all 455 contacts have been excluded from SARS-CoV-2 infection and we conclude that the infectivity of some asymptomatic carriers of SARS-CoV-2 may be weak.
