It is not true that Covid-19 tests can target the brain

It is not true that RT-PCR-type tests used to detect Covid-19, which insert a kind of cotton swab into the nose, can reach the pineal gland and cause brain infections, as the post claims (see here). The instrument used, known as a swab, reaches the nasopharynx or throat and can only pass through the membranes and bone structure that separates the nasopharynx from the brain in case of excessive force, fracture or bone malformation. The pineal gland is also not at the base of the brain, but at the center of the organ.

This misinformation has mainly circulated in groups on Telegram, where it accumulates about 20 thousand views (join the Aos Fatos group on the platform). Similar posts were also shared dozens of times on Facebook.

Avoid all nose samples in the world. It can pass through the sieve network and destroy the pineal gland with full coverage. Bacteria are created, which can then infect the brain. An estimate says that one in 10,000 died from this test. SAY NO TO TESTS!

Posts are misleading when they say that RT-PCR testing, which detects Covid-19, can destroy the pineal gland and open an access for bacteria to infect the brain. The examination only affects the patient’s nasopharynx or throat. The pineal gland is responsible for producing melatonin, a hormone that helps regulate sleep, and is located inside the brain. There are membranes and a bone structure between the brain and the nasopharynx, an area reached by the Covid-19 sample inoculation. According to the SBPC / ML (Brazilian Society of Clinical Pathology and Laboratory Medicine), the swab, the equipment used in the study, would only be able to reach the brain in case of fracture or malformation of this bone structure.

“The brain is separated from the nasopharynx. There is no reason to believe that you are perforating a bone every time you do this examination,” explains Dr. João Renato Rebello Pinho, a member of the SBPC / ML. “One would have to do it with very unreasonable violence and the incidence of infection would be very high. One would have meningitis, brain infections caused by bacteria present in the nasopharynx.”

The image used to illustrate the disinformation publications does not show an RT-PCR examination, but an endoscopic operation to remove a tumor in the pituitary gland, the gland responsible for the production of various hormones. In this case, it is necessary to remove the bones between the nasal cavity and the brain to perform the procedure.

The message even fails by locating the pineal gland at the base of the brain. As neurologist José Renato Felix Bauab of Sírio-Libanês Hospital explained in an earlier check-up, this structure is located in the center of the body.

In the book “The Night Oracle – The History and Science of Dream” (Cia. Das Letras), neuroscientist Sidarta Ribeiro explains the relationship between melatonin production and sleep. Melatonin, the sleep-inducing hormone produced in the first half of the night by the human pineal gland, appears to have originated 700 million years ago when marine worm-like animals developed cells capable of capturing light and moving “with the stroke of the cilia. during sleep. day, but not night,” he writes. “The mechanism behind this dichotomy would have been the nocturnal production of melatonin, which in the absence of light stimulates neurons to cancel the movements of the cilia.”

Ribeiro further concludes: “Between us and the worms, despite the enormous evolutionary distance, the function of the ancestor was maintained by certain molecular mechanisms, such as the role of melatonin in inducing sleep.”

Sibenet. When searching for the word “sibeneta”, mentioned in the informative piece as a structure that the cotton swab could cross, to the facts found only one similar word in the Danish language: “sibenet”, which can be translated to “etmoid bone”. This is the porous bone that forms part of the skull and forms the nasal cavity. It does not have a passage or channel that allows the swab to reach the brain.

to the facts also found no study or report in Portuguese or English with data that one in 10,000 people who underwent the test would have died. There are reports of a child in Saudi Arabia who died after the cotton swab broke inside his nose, and a woman who had her skull pierced during the examination but survived. In this second case, however, the patient had a malformation at the base of the skull.

RT-PCR is considered by the Ministry of Health to be the gold standard for the detection of Sars-CoV-2 because it has a high degree of sensitivity and specificity. The body recommends that anyone with the flu or respiratory syndrome take the test to check for the presence of the new coronavirus in the body.

In another check, in July 2020, Aos Fatos had already explained that the test to diagnose Covid-19 does not pose a risk of inflammation in the brain. This piece of disinformation originally circulated on Spanish- and Portuguese-speaking networks in mid-2021.
