Best research study so far that explains most of the questions: https://www.ncbi.nlm.nih.gov/books/NBK554776/ Issues:
-
Close proximity, Radius and Time Span
-
Risk factors
-
Symptoms assessment - risk group
-
What would be great to be done.

Close Proximity: + Risk group https://wwwnc.cdc.gov/eid/article/26/6/20-0412_article one study in China suggest that close proximity is considered people that work in the same place: vendors in a grocery store, healthcare professionals, people in a mall. Right now close contact is considered to be 2 m or 6 feet. We also have some variables like time span and also location. So if we have a person infected with covid and it
s in the same area with us for more than 15 minutes and the person cough or sneez and some droplets get into our hands, clothes, face, we can get the virus, this is the most important and highest risk thats social distancing it`s a law now.
*staying in the same room with another patient for more than 15 minutes or less than 2 meters distance for a patient with positive test: On the basis of contact tracing, 41 health care workers were identified as having exposure to aerosol-generating procedures for at least 10 minutes at a distance of less than 2 meters from the patient. (The aerosol-generating procedures included endotracheal intubation, extubation, noninvasive ventilation, and exposure to aerosols in an open circuit (4). All 41 health care workers were placed under home isolation for 2 weeks, with daily monitoring for cough, dyspnea, and myalgia and twice-daily temperature measurements.) https://www.cdc.gov/coronavirus/2019-ncov/hcp/guidance-risk-assesment-hcp.html
"Data are insufficient to precisely define the duration of time that constitutes a prolonged exposure. However, until more is known about transmission risks, it is reasonable to consider an exposure greater than a few minutes as a prolonged exposure. Brief interactions are less likely to result in transmission; however, clinical symptoms of the patient and type of interaction (e.g., did the patient cough directly into the face of the HCP) remain important. "
high-risk exposures = prolonged close contact with patients with COVID-19 who were not wearing a facemask while people nose and mouth were exposed to material potentially infectious with the virus causing COVID-19.
*** Being present in the room for procedures that generate aerosols or during which respiratory secretions are likely to be poorly controlled (e.g., cardiopulmonary resuscitation, intubation, extubation, bronchoscopy, nebulizer therapy, sputum induction) on patients with COVID-19 when the healthcare providers’ eyes, nose, or mouth were not protected, is also considered high-risk.
Medium-risk exposures generally =prolonged close contact with patients with COVID-19 who were wearing a facemask while patient nose and mouth were exposed to material potentially infectious with the virus causing COVID-19.
Low-risk exposures = brief interactions with patients with COVID-19 or prolonged close contact with patients who were wearing a facemask for source control while HCP were wearing a facemask or respirator. Use of eye protection, in addition to a facemask or respirator would further lower the risk of exposure. All data from CDC.
As I said, location is important in measuring what are the risk to get the virus:
New studies have found that:
https://www.nejm.org/doi/full/10.1056/NEJMc2004973
So we can say that if you are wearing gloves your chances to get the novel virus are really small.
Symptoms:
a)Fever : >37.8 C or >100.0F F (85-99%) If you have high fever you should immediately call a medical professional. Fever in people 65+ is usually lower grade so if a people 65+ or any people associated health condition such as cancer, pregnancy, HIV, hypertension, diabetes mellitus has to call a doctor for further investigations.
- High fever 100+ F for 3 days = increase the risk to have undoing lung infection with Covid 19. High fever and progress of infection: "Although high fever was associated with the development of ARDS, it was also associated with better outcomes among patients with ARDS. " (https://www.ncbi.nlm.nih.gov/pubmed/32167524) b) Dry cough (73-81%) c) Shortness of breath (60-67%)
I will add more info later.

Background: This tool is a privacy preserving voluntary COVID-19 self-reporting platform for contact tracing. Users share their (encrypted) location history and test status, get a notification if you have been in proximity to higher risk locations.
We need help defining what high risk locations overlap means. Questions we have are:
