A screenshot of a social media post shared on Facebook, states it’s illogical that nasal swabs rather of mouth swabs are used to evaluate for coronavirus infection when the infection is so contagious it can be spread out in beads of saliva.
” DNA can be in your home through the mail with a simple mouth swab however the HIGHLY CONTAGIOUS COVID-19 in your MASK COVERED MOUTHS can’t be tested with a mouth swab???” it asks. “Does this sound SENSIBLE??”
It then asks: “Is it possible that instead of retrieving a SAMPLE, they could actually be IMPLANTING SOMETHING???”
Covid-19 is a breathing illness that spreads in small virus-carrying droplets launched when an infected person coughs, sneezes or speaks.
It is mainly tested using a nasopharyngeal swab. The 15- centimetre swab is inserted through the nostrils into the cavity in between the nose and mouth and turned for about 15 seconds. It is then sent out to a laboratory for testing.
Why are nasal swabs utilized instead of mouth swabs?
‘ A number of drinking buddies’
They report that the user admitted to coming up with the post with “a couple of drinking friends” and did not base it on any sources.
Covid-19 tests that utilize saliva samples are currently being trialled. One being evaluated by Southampton University in the UK could allow people to collect their own sample in the house by spitting into a pot.
But research shows that saliva testing might be less delicate than nasal testing, as saliva tests produce a lower concentration of the infection compared to nasal swabs.
This suggests that saliva testing might misdiagnose some people with Covid-19, who would have been properly detected with nasal screening.
DNA checks various to Covid-19 tests
It is likewise unreliable to compare Covid-19 screening to DNA testing. According to the US National Library of Medication, “nearly every cell in the body has the very same DNA” which lies in the cell nucleus.
DNA screening is done on tissue samples to test genes in cells. Covid-19 testing identifies the existence of Covid-19 viruses in upper respiratory specimens such as mucous, saliva, and sputum.
It is possible to check for Covid-19 using saliva samples. But these tests aren’t yet as accurate as tests using nasal swabs.
And could “they” be “inserting something”? If an object was shoved into your nose on the end of a 15- centimetre swab, you ‘d understand it.
