Sống chung Covid-19 như thế nào?

CORONA VIRUS INTRODUCTION TIME, LIFETIME AND SPREAD OF COVID-19 Determining the incubation period of Corona is considered key to controlling the spread of the disease. Covid-19 patients usually show obvious symptoms on the 5th day after infection with Sars Cov virus 2. Corona virus incubation period, life time and spread of Covid-19 Experienced many diseases and drawings The scenario of a serious pandemic may occur in the future, however, the world is still in chaos in the face of Covid-19. The rapid increase in the number of Covid-19 infections globally has put many countries in a state of emergency with an unprecedented chain of challenges. According to experts, The ability to spread directly from person to person and the risk of contracting the virus from an asymptomatic patient (who is in the incubation period of the Corona virus) are the main reasons for the outbreak of Covid-19 and its rapid spread globally. According to the recommendations of the Ministry of Health, isolation within 14 days is an especially important measure for people who have close contact with cases, suspected cases, cases returning from epidemic areas, especially especially those returning from China. What is the incubation period? The incubation period for nCoV is understood as the time between the first exposure to Sars Cov 2 virus and the onset of symptoms. The incubation period for Corona can vary from person to person. How long is the usual incubation period for Corona? 1. For Coronavirus Current estimates show, Corona virus strains such as MERS and SARS have an incubation period of about 2-11 days. Like other respiratory diseases, after the end of the incubation period, people infected with Coronavirus will show symptoms including runny nose, sore throat, cough and fever ... The disease can progress to severe in some people when causing out acute pneumonia. More dangerously, Covid-19 can quickly cause death to high-risk subjects such as the elderly, people with chronic diseases (diabetes, heart disease, cancer, chronic obstructive pulmonary disease, COPD, etc.). 2. For new strains Acute respiratory infections caused by new strains of Corona virus may appear symptoms after an incubation period of 2 to 14 days, an average of 5 days. During this time, the virus can still infect others. However, many studies also show that, There will be a small number of cases where the incubation period for Sars-Cov 2 can be longer than 14 days. Research conducted by the Johns Hopkins Bloomberg School of Public Health (USA) shows that, out of 10,000 subjects infected with Covid-19, about 101 cases showed the first symptoms after 14 days. Therefore, experts say that contact with people without symptoms does not mean it is safe. In other words, Covid-19 can be contagious even before the first symptoms appear. Corona virus survives in the environment How long does Corona virus live in the air is a question of many people. According to experts, the Corona virus is not light enough to be suspended in the air, its way of spreading can only be through droplets from an infected person. Being able to survive for a long time in the environment and stick to contact surfaces is a factor that makes Corona virus a potential risk of spreading disease to the community. At what temperature does the Corona virus live? Corona virus can survive with temperatures around 4-20oC for 5 days. It only loses its ability to infect after 30 minutes if it exists at temperatures from 56oC. Ultraviolet rays and common medical disinfectants can kill the virus within 60 minutes. Depending on the environment, temperature, and humidity, the Corona virus has different ability to live. Studies show that at 4oC, the Corona virus has the ability to live for about 1 month. From 20-25oC the virus will weaken, live about 5-7 days. From 33oC or higher, Corona virus weakens quickly, less likely to cause disease. Corona virus does not fly from the contact surface to the nose and mouth area by itself, all through the hands, therefore, frequent hand washing with soap, Disinfectant solution, wearing a mask properly, practicing safe distance measures are very important. How long does the Corona virus live in the air? Corona virus can survive in droplets suspended in the air at normal temperature up to 3 hours after being released from a cough. The incubation period of the Corona virus, how long it lives and spreads Covid-19 How long the corona virus lives in the air is not the main factor in preventing pathogens. It is important that the attitude of compliance and correct implementation of preventive methods minimizes the possibility of direct and indirect exposure to the disease-causing virus. How long does the Corona virus survive on surfaces? Corona virus lives the longest on plastic and steel materials, lasting up to about 3 days, but the amount of virus on the surface will decrease over time. Many studies also show that, The life time of Corona virus on surfaces such as stainless steel, copper or cardboard will be lower, especially this virus can only live in the air for about 3 hours. Surface Life time Plastic and steel 72h Stainless steel and copper 48h Hardcover 24h Air 3h Incubation time Corona virus, life time and spread Covid-19 Is Corona virus contagious? How Sars Cov 2 virus is transmitted is a matter of special concern to the community. Sars Cov 2 virus spreads through airborne droplets when an infected person coughs or sneezes, spreads at an extremely rapid rate in the environment, through surfaces, persists for hours. At its most dangerous, the Corona virus spreads from one patient to dozens, even hundreds of others, known as a "super-contagion" phenomenon. According to estimates, an average person infected with Sars Cov 2 virus can infect at least 3-4 people, spread even if there are no symptoms or symptoms are not clear, this is the reason why Covid-19 is easy to break out. rapid growth in the community. Routes of transmission of Covid-19 Person-to-person transmission Close contact with sick people (coughing, sneezing, talking, breathing, spitting...) Covid-19 is spread mainly through close contact from people. person to person, including those who are within 2m of each other. People infected with Covid-19 without symptoms or with unclear symptoms can still infect others with the virus. When talking, coughing, sneezing... droplets from the respiratory tract of a person infected with Covid-19 will infect healthy people. Larger droplets will fall through the air due to gravity. Droplets and smaller particles are dispersed through the air. The further away, the lower the density of droplets containing the virus. Airborne (shared space with sick people, respiratory transmission) Airborne transmission is a serious form of infection that makes the virus more likely to explode in the community. In many cases, the Sars Cov 2 virus can still infect at a distance of more than 2m. Airborne transmission usually occurs in enclosed environments, where ventilation is not available. Contagion by contact with contaminated surfaces Droplets containing the virus can land on surfaces and objects and stay there for hours. A healthy person can get Covid-19 by touching a contaminated surface or object and then touching their nose, mouth, or eyes. Contamination by contact with surfaces is thought to be an uncommon form of infection. Infection between humans and animals (rare) The US Centers for Disease Control and Prevention (CDC) report shows that a small number of pets in the world including dogs and cats are present of the Sars Cov 2 virus, which is mainly caused by contact with infected people. Until now, the risk of transmission of Covid-19 from animals to humans was thought to be rare. 4 tips for wearing a mask when wearing glasses, preventing Covid-19 Risk levels of Covid-19 infection In order to actively prevent and control acute respiratory infections caused by Covid-19, the Ministry of Health recommends that people take care take a number of measures such as: wearing masks properly, washing hands frequently, not gathering in crowds, not traveling to epidemic areas; use cooked foods; keep the body warm, promote health by eating, resting, living properly, According to experts, if a normal person goes out and still adheres to medical recommendations to prevent the Covid-19 epidemic, that person is still likely to have levels of risk of being infected with Covid-19- 19, in which the risk of infection from asymptomatic people (who are in the incubation period of Corona disease) is very large. The risk levels for Covid-19 infection are sorted from low to moderate (from 1 to 4), moderate to high (from 5 to 7) or high (levels 8 to 9). High level of risk (level 8 to 9) Going to a place of worship (church, temple…) with more than 500 people gathered (level 9) Going to a stadium, football field… (level 9) Going to pubs, bars (level 9) Going to the gym (level 8) Going to a buffet restaurant (level 8) Moderate to high risk (level 7) Hugging, shaking hands (level 7) Play basketball, There is no specific drug for prevention and treatment of acute respiratory infection caused by a new strain of Sars Cov 2. Current treatment is mainly symptom relief. Scientists are studying to isolate and determine the gene structure of Corona virus to create a vaccine, a specific weapon against Sars Cov 2 virus effectively. During this time, the best prevention method is still to limit exposure; keep a safe distance, wear a mask properly; wash your hands often; clean house; Timely medical declaration. Especially not to be subjective because Covid-19 is still capable of spreading during the incubation period of Corona. Current treatment is mainly symptom relief.
