  • A new study by the Centers for Disease Control and Prevention (CDC) shows that it is easy to get the coronavirus from people living at home.
  • The report shows that according to daily self-management tests, about half (53%) of the surveyed who live with COVID-19-positive patients become ill within a week.
  • The disease spread rapidly, spreading 75% of infections within 5 days.
  • The authors of the study said that people “suspect that they may have COVID-19 and should be isolated, stay at home, and use separate bedrooms and bathrooms where feasible”.

The Centers for Disease Control and Prevention (CDC) report released on Friday shows that no matter how old you are, getting the coronavirus from people who live with you can be quick and easy.

The study has been conducted in more than 100 families in Nashville, Tennessee, and Marshfield, Wisconsin since April, and the study found that approximately half (53%) of the study participants were positive for COVID-19 with sick patients In response, the disease was caused by the coronavirus, which made myself sick within a week. According to their daily self-examinations, 75% of these secondary cases tested positive for the virus within five days or less.

The study author wrote in the report: “People who suspect that they may have COVID-19 should be isolated, stay at home, and use separate bedrooms and bathrooms where feasible.” He emphasized that isolation should be when people suspect themselves. You may get sick immediately after birth or even before any tests are performed.

It is dangerous to be in the same room with the patient

In this study, most of the sick patients said that they spent many hours (four or more) with people living with them the day before they felt unwell. In the period before the onset of symptoms, it is precisely when health experts suspect that the virus is most infectious.

Mike Ryan, Executive Director of Health Emergencies of the World Health Organization, said earlier this year: “This is because this disease may spread at that moment, so it is very easy to spread.” The reason for the restriction to spread to all parts of the world.”

A person sitting in a bed: Most people who are infected with COVID-19 will have mild symptoms, none at all, and no serious infections, but they can recover completely. However, according to Dr. Anthony Fauci, a major infectious disease expert in the United States, many people suffer long-term health damage due to infection. In the virtual event of the National Medical College,

Another factor that is not conducive to people sharing housing with sick patients is airflow. Coronavirus spreads well between people in poorly ventilated rooms, and in poorly ventilated places, so people are infected in their daily life, breathing, sleep, and eating.

Don Milton, a virologist at the University of Maryland, previously told Insider: “We know that the biggest risk is these enclosed indoor environments.”

(However, as the study authors pointed out, certain participants are always likely to be infected in other ways.)

In this study, 40% of sick patients slept in the same room with another member of the family before they knew they were sick. The age of the study participants ranged from under 12 to over 50. Study author Melissa Rolfes (Melissa Rolfes) told The Insider in an e-mail that family members may opt out of the study, but this “does happen, but rarely happens”.

If you must share the space at home with the patient, wear a mask

The authors of the study suggested that the sick and everyone in the family should start wearing masks as soon as they think they have the virus, “especially in shared spaces that cannot be properly evacuated.” You may also want to open some windows (if the weather is not too cold) or move some fans to improve air circulation and blow away virus particles.

If you live with someone who has the virus, you should also isolate those who have not lived in the home within two weeks. This is because you may be infected with the virus and may spread it to others without knowing that you are contagious. Indeed, in this study, when the infection was first detected by the test, only 40% of sick roommates who subsequently became ill had any symptoms.

Dr. Rishi Desai, chief medical officer of Osmosis and former epidemic intelligence service officer of the CDC, told Insider recently: “Usually, if you develop symptoms, it will be between two and twelve days.”
