The symptoms of long covid are extremely bothersome for many convalescents. The data shows that up to 80% of them struggle with them. of them. Recent studies also indicate that traces of the virus are the longest in the brain. What is the reason for this?
- The most common symptoms of long covid include: olfactory and taste disturbances, fatigue, headaches, concentration and memory disorders, and anxiety disorders.
- Thanks to laboratory methods, scientists were able to confirm the presence of the virus, among others in the heart, small intestine, lymph nodes, blood plasma and brain
- Researchers found traces of the virus throughout the brain up to 230 days after the onset of symptoms
- Long covid may result from the survival of virus debris in the body

What is long covid?
Long covid is a colloquial term for a set of symptoms that appear after a coronavirus infection and persist for more than three months after the end of the infection. Due to the fact that COVID-19 is a multi-system disease and does not only affect the respiratory tract, the most common symptoms of long covid are:
- changes in the sense of smell and taste
- tiredness,
- Headache,
- concentration and memory disorders,
- anxiety disorders.
These symptoms indicate the presence of a virus in the human nervous system, an indispensable element of which is the brain. According to a study published on December 20, 2021 in Research Square, this is exactly what it is the virus lasts the longest in the brain. How it’s possible?

Research methodology
Scientists have noticed that the burden of infection outside the airways and the timing of virus clearance are not well characterized, especially in the brain area. In order to investigate how the virus replicates, Investigators autopsied 44 people who died of COVID-19.
We have shown that SARS-CoV-2 is widespread, even among patients who died with asymptomatic or mild COVID-19, and that viral replication is present in many extrapulmonary tissues early in infection. In addition, we detected SARS-CoV-2 RNA in a number of anatomical sites, including regions throughout the brain, for up to 230 days after onset of symptoms.

The drug was commented on in an interview with abcZdrowie. Bartosz Fiałek, rheumatologist and promoter of medical knowledge about COVID-19. The expert pointed out that thanks to laboratory methods, scientists were able to confirm the presence of the new coronavirus, including in the heart, small intestine, lymph nodes, blood plasma, as well as the brain.

The cause of long-term COVID-19 symptoms
The expert emphasizes that the postmortem presence of viruses in our body is completely natural. However, he points out that the conducted research may show the essence of long covid. According to the expert, both specific and non-specific immune responses work most strongly in the respiratory system.
Why does it stay so long outside the lungs? Perhaps it is because the immune response – nonspecific and specific – is less robust than the airways.

The rheumatologist also cites one of the popular hypotheses presented by scientists who indicate that long covid is the result of the survival of virus debris in the tissues of our body. In their opinion the body “does not clean” itself completely of the virus, therefore the pathogen present in the body continues to affect the immune system, leading to chronic disease symptoms.
