The opinions are different. But actually, it is essential to know how long time the Covid-19 patient will be in negative result from his/her initial day of infection.
This is still an undetermined issue. It varies widely on the gravity of infection, viral load, viral strain, patients comorbidity, management received, treatment environment, etc.
Articles based on Covid-19 disclose that the recovery depends on a person's immunity system. A person with strong immunity gets well as soon as possible. Otherwise, it takes time.
From current circumstances, I have found the recovery took 20-25 days minimum, and in some cases, the time extends.
Although several symptoms remain after the negative test result in many cases, it takes more time to get rid of them. Thank you.

Using available preliminary data, the median time from onset to clinical recovery for mild cases is approximately 2 weeks and is 3-6 weeks for patients with severe or critical disease. https://www.who.int/docs/default-source/coronaviruse/who-china-joint-mission-on-covid-19-final-report.pdf#:~:text=Using%20available%20preliminary%20data%2C,severe%20or%20critical%20disease.
People with mild symptoms should make a good and speedy recovery. The fever should settle in less than a week, although the cough may linger. A World Health Organization (WHO) analysis of Chinese data says it takes two weeks on average to recover. https://www.bbc.com/news/amp/health-52301633
The window period from infection to first symptoms on average is 5 days (*Nandini Sethuraman et al). Most of the Korean Government studies show that viral cultures (obtaining viruses) are up to 10m days. RT PCRs are positive on average up to 14 days, hence the isolation of 14 days, but the expulsion of portions of non-infectious genetic material makes the PCR positive in some up to 92 to 96 days, being non-infective. window, is what makes this SARS CoV2 virus highly transmissible, hence the very important use of the mask by the population to reduce airborne transmission that can reach 9 meters, with a greater possibility of contagion up to two meters, from There, maintaining the social distance of two meters between person and person, the high transmissibility through the ocular mucosa to the brain and heart (without giving pulmonary symptoms and Negative CRP) is that it indicates to use the face or eye protector, even more so by the staff health, is at stake to demonstrate transmissibility through the skin, since other coronaviruses are expelled by sweat

Para lectores de idioma Español: El Periodo de Ventana desde que se infecta hasta que da los primeros síntomas en promedio es 5 días (*Sethuraman, Stanley et al) la mayoría de los estudios del Gobierno Coreano demuestran que los cultivos virales (obtención de virus) es hasta los 10 días. Las PCR RT son positivas en promedio hasta 14 días, de ahí el aislamiento de 14 días, pero la expulsión de porciones de material genético no infectante, hace que la PCR sea positiva en algunos hasta 92 a 96 días, siendo no infectantes, El periodo de ventana, es el que hace que este virus SARS CoV2 sea altamente transmisible, de ahí el uso importantísimo de la mascarilla por la población para disminuir la transmisión aérea que puede llegar a 9 metros, con mayor posibilidad de contagio hasta los dos metros, de ahí el mantener la distancia social de dos metros entre persona y persona, la alta transmisibilidad a través de mucosa ocular a cerebro y corazón (sin dar síntomas pulmonares y PCR Negativa) es que indica usar el protector facial u ocular, más aun por el personal de salud, Esta en juego el demostrar la transmisibilidad a través de la piel, ya que otros coronavirus se expulsan por el sudor y si algo sale, también puede penetrar , e ahí el uso de los trajes de Protección Personal para el Equipo de Salud
*Stanley, Sethuraman et al Compartieron su trabajo conmigo, a quienes estoy muy agradecido por que permitieron tener una mejor visión de algunos pacientes cuyo PCR RT se mantenía positivo.
