I decided to fantasize a little about how this whole situation with the virus could have happened... a little fantastic, but still... this scenario is quite possible, and like this: "Somewhere in a secret laboratory, a new virus was studied, but something gone wrong ... " Text from books: 1. "Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease was first identified in December 2019 in Wuhan, the capital of China's Hubei province, and has since spread globally, resulting in the ongoing 2019–20 coronavirus pandemic. First confirmed case of what was then an unknown coronavirus was traced back to November 2019 in Hubei province. Common symptoms include fever, cough, and shortness of breath. Other symptoms may include fatigue, muscle pain, diarrhea, sore throat, loss of smell, and abdominal pain. The time from exposure to onset of symptoms is typically around five days but may range from two to fourteen days." 2. "Precautions must be taken to minimise the risk of virus transmission, especially in healthcare settings when performing procedures that can generate aerosols, such as intubation or hand ventilation. For healthcare professionals caring for people with COVID-19, the CDC recommends placing the person in an Airborne Infection Isolation Room (AIIR) in addition to using standard precautions, contact precautions and airborne precautions. The CDC outlines the guidelines for the use of personal protective equipment (PPE) during the pandemic. The recommended gear is: PPE gown, respirator or facemask, eye protection, and medical gloves. When available, respirators (instead of facemasks) are preferred. N95 respirators are approved for industrial settings but the FDA has authorised the masks for use under an Emergency Use Authorisation (EUA). They are designed to protect from airborne particles like dust but effectiveness against a specific biological agent is not guaranteed for off-label uses. When masks are not available, the CDC recommends using face shields or, as a last resort, homemade masks." Text from messege: “Tonight, at 1 hours 03 minutes, the investigated object was leaked, immediately announce a general alarm and close all entrances and exits from the city, declare universal quarantine!”
