You get up in the morning and spit into a test tube. Or, when you get up, you put the sponge in your mouth, soak it in your saliva, and then spit it into the test tube. This is the daily life of every Olympian in the Tokyo Olympics. Kyodo News Agency said that next week, Japanese organizers will recommend that Olympians perform a less invasive saliva test instead of wiping.
In the new option, nasal and throat swabs will not be required. On the other hand, everyone must pass the test every day. It’s just a plan to reduce the pressure associated with covid research, which is much less at the Olympics-once every four days.
“It must be 72 hours before crossing the Japanese border, we have to test […] After crossing the Japanese border, at Narita Airport [65 km od Tokio]A quick test will run them all. The information we have is that if any of these tests are positive, after a few hours at this airport, the athlete will undergo two more independent tests. As we all know, there is a high probability of errors in quick tests. This is why the organizers introduced this solution. However, when it comes to the Olympic Village, it is said that tests are conducted every four days. However, it may be more frequent in some exercise tests and less frequently in others-Marcin Nowak told us recently. 100 days before the event, we had a conversation with the head of the Polish Olympic delegation to be held in Tokyo on April 14.
Just a week later, Kyodo News reported that the idea of testing athletes every four days no longer worked. According to reports, IOC President Thomas Bach and Tokyo 2020 Olympic Organizing Committee Chairman Seiko Hashimoto agreed that stricter testing protocols must be implemented.
In Japan, there are currently approximately 4,000 COVID-19 cases per day. Kyodo News reported that Prime Minister Suhide Yoshihide is considering a state of emergency in Tokyo. All this inhibits the growth of infections.
The National Olympic Committee will be notified next week about new ideas for testing Olympic participants. A special anti-covid manual will contain detailed instructions on how to perform a saliva test. It may be necessary to have a research supervisor in the Olympic Village. Organizers want to make sure that everyone will donate their saliva.
“We have no binding confirmation. This is what this research looks like. The International Olympic Committee and the Organizing Committee are working on various solutions-you can read from the script-and various plans are being prepared. The final decision will be made later. Made. Date. Then we will learn about the details of the study and the health system”-he wrote us to the Communication Office of the Polish Olympic Committee.
Is a saliva check a good idea? What are their functions? Dr. Paweł Grzesiowski, an expert of the Supreme Medical Council’s fight against COVID-19, made a comment on Sport.pl:
-The saliva test has been in some countries for some time, but the research is still in progress. Poland has not yet registered and verified the test. You must check whether they have similar sensitivity and specificity to smear tests. We are waiting for such tests to enter the market. Performing an inspection will be a great simplification, because you can give up the swab. This is a promising idea.
-Saliva test has been used in the United States, the United Kingdom and Asia. But they are mainly used for genetic testing or PCR in symptomatic patients. There must be a difference here-these will be rapid tests, many competitors in the Olympics will be vaccinated and will also recover, and the question that arises here is whether these tests can detect early infections. I do not know.
The rapid saliva test can detect viral antigens in asymptomatic patients, and its sensitivity is lower than in symptomatic patients. So far, nose and throat swabs are more sensitive than saliva tests. This is because there are fewer viruses in saliva. And you need to get the right amount of saliva to make the test reliable. Here, you need to find a suitable collection technique-for example, a sponge test. A person sucks a sponge into his mouth, soaks it with saliva, and then throws the sponge into a test tube. This is a good way. Because directly into the test tube, one person will spit out half an inch of saliva, while the other will spit less saliva, which is troublesome. The key is that the amount of material collected from the oral cavity is moderate, and this saliva stays in the oral cavity for a long time.
