Regarding home epidemic prevention, Liu Yuanjun, a second-level researcher at the Hohhot Municipal Health Commission, introduced that at present, the channels for transmission of new coronary pneumonia that can be determined are mainly direct transmission (droplet transmission), aerosol transmission and contact transmission.
" aerosol " refers to a dispersion system formed by suspending a solid or liquid in a size of 0.001 to 100 microns in a gas. Solid aerosols are often called smoke, while most liquids are called fog. Pathogen microorganism is attached to aerosols present in the atmosphere or other environments, causing infection after being inhaled into the respiratory tract by others. In addition to being able to spread through drainage and exhaust systems, the most important transmission environment is still in the air.
has relatively more living at home, the family environment is relatively closed, and the time spent at home is relatively long. During the epidemic, you should pay attention to preventing the spread of the new coronavirus through aerosols. Doing the following four points can effectively prevent the spread of viruses through aerosols.
First, open windows to ventilate without . Ventilate at home at least once every morning and afternoon, and the ventilation time is at least 30 minutes. Air circulation can effectively eliminate the spread of aerosol in a confined space. If you have air conditioning at home, remember to turn on fresh air mode.
Second, be careful with sewer pipes and flue. The sewer is too dry or has no return water curve, and the protection is lost. The aerosol in the sewer public pipeline may enter the home on the same unit with the airflow. Timely ensure that water is stored in the backwater curve, and the water will seal the pipeline and effectively prevent aerosols from entering. The sewer outlet at needs to be injected more than 2 times a day, at least 350 ml each time. Fill a plastic bag and tie it tightly, and place it on the floor drain to be the best sealing cover. When flushing the toilet, cover the toilet lid first to avoid aerosol splashing outside the toilet. When cooking, remember to open the window for ventilation to avoid flue airflow. If there is check valve in the exhaust duct, there is no need to open the window.
Third, you must clean your home frequently. performs wet cleaning at least once a day and disinfects if necessary. Especially the bathroom and kitchen, it must be kept clean.
Fourth, develop good hygiene habits. During the epidemic, no matter what environment, we must adhere to measures such as washing hands frequently, wearing masks, ventilating frequently, gathering less, and maintaining a safe distance, and taking good self-protection.
