Recently, "cross-infection occurred at the sampling site of New Crown Nucleic Acid Rapid Test resulting in multiple confirmed infections." This news has sparked widespread concern and discussion.
Large-scale new crown nucleic acid rapid test multiple rounds of testing has become an important tool for the prevention and control of the current epidemic, but it is also a scenario where the probability of cross-infection is extremely high.
The so-called cross-infection refers to the presence of pathogens in nature, such as bacteria, viruses, fungi, etc. invade the human body, causing a systemic or local inflammatory response. Three conditions must be present for cross-infection to occur, i.e., infectious source, transmission route, and susceptible population, and these conditions can be met in a large-scale New Crown Nucleic Acid Rapid Test sampling site.
So what should I pay attention to when sampling for Nucleic Acid Rapid Test to avoid cross-infection?
Traveling!
On the way to perform Nucleic Acid Rapid Test sampling, you should be careful not to gather, not to stay, and as far as possible to use walking, cycling or driving a private car and other modes of transportation; if you use public transportation, you should ensure that you bring a good quality protective mask throughout the whole process, and try to avoid touching the objects and public facilities on the car, and not to rub your eyes or touch your face with your hands. Before taking a cab or online car, open the door for ventilation, put on your own mask and remind the driver to wear it.
Attention in the queue!
When queuing for nucleic acid sampling, strictly follow the order, follow the instructions of the staff on site, maintain a 1-meter interval, and do not communicate closely with others to avoid the spread of the virus due to social proximity. Cover yourself with a tissue or elbow when coughing in the queue, cooperate with the site staff to register for temperature measurement, and take relevant preventive and control measures
Attention to sampling!
Avoid direct contact with the sampling table, do not touch the doctor's clothing, and do not place personal belongings on the sampling table when performing rapid new coronary nucleic acid test sampling. Since a sampling physician will be sampling multiple individuals, the sampling table may be untimely or incompletely disinfected during sampling. During pharyngeal swab collection, you may experience throat discomfort and when you want to cough and sneeze or vomit, remember not to point at the medical staff or others, and have tissues ready to prevent droplet transmission.
Leave the field note!
Pay attention to hand hygiene after the New Crown Nucleic Acid Rapid Test sampling is completed, and wipe your hands with non-abrasive alcohol if you can. Prepare a new spare mask in advance, put on a new uncontaminated mask after leaving the sampling site, put the discarded mask into the designated medical garbage bag and leave immediately, do not stay at the sampling site.
Note the results!
At present, large-scale new crown nucleic acid rapid test are used in the mixed collection detection mode, the sampling samples of multiple people in the same preservation tube for testing thereby achieving efficient new crown nucleic acid rapid test.
At the same time, due to the progress of the New Coronary Nucleic Acid Rapid Test technology, the reaction speed is increased by 1 hour, which can quickly New Coronary Nucleic Acid Rapid Test results. After the Nucleic Acid Rapid Test is done, you need to check the results of the Nucleic Acid Rapid Test in time. If a positive test is found, contact local government agencies and your own close contacts in time to avoid mass transmission.
In addition to cross-contamination at the sampling site of the Nucleic Acid Rapid Test, most places where people gather are at risk of cross-contamination and daily protection is especially important.
