According to the Israeli Ministry of Health, throat swabs and antigen test kits could help detect people with Omicron variants earlier when the virus enters the throat and saliva instead of the nose.
On January 10, Sharon Alroy-Preis, director of public health services at the Israeli Ministry of Health, suggested that people who self-test for COVID-19 should collect throat and nasal secretions using an antibody test kit. Quickly. Increased risk of infection. Omicron variant detection capabilities.
Speaking on Israeli Army Radio, Alroy-Preis said antigen test kits widely used in Israel are less sensitive than PCR tests in detecting the SARS-CoV virus. 2..
To increase sensitivity, Israeli health authorities now recommend the simultaneous use of throat and nasal secretions, although these are not the manufacturer’s instructions.
The recommendation stands in stark contrast to the U.S. Food and Drug Administration (FDA) recommendation, which states that users need to follow the manufacturer’s instructions to use swabs incorrectly. . . May be harmful to patients.
Ms Alroy-Preis said everyone should be tested multiple times during contact with a patient, or wait at least three days after contact with a patient before using an antigen rapid test kit.
The Israeli Ministry of Health has yet to comment on whether the swabs tested were effective, and Israel has consulted with the manufacturer on the matter.
When the Omicron variant led to an unprecedented increase in new daily infections in Israel, Israeli testing centers struggled to cope with new developments, health officials said. Home PCR testing must be prioritized for high-risk groups, namely young adults who have been vaccinated against COVID-19, to prevent contact with infected individuals.

Some infectious disease experts also advocate swabbing the throat with antigen-testing kits because people infected with the virus have been able to pass the Omicron variant to others when the virus enters the throat and saliva. Not the nose.
A study published last week in medRxiv tracked 29 Omicron mutants working in high-risk fields.
The men underwent PCR and antigen testing on consecutive days. The saliva PCR test detected the virus, on average, 3 days before a positive nasal swab test.
Israel has recorded a total of 1.5 million COVID-19 infections and more than 8,000 deaths since the outbreak of COVID-19.
About 60 percent of Israel’s population has been vaccinated against all necessary COVID-19 vaccines, according to the Ministry of Health.
