ERBIL (Kurdistan 24) – In a recent study conducted at Imperial College London, British scientists discovered that some individuals did not contract Covid-19 despite being exposed to the virus.

This discovery is attributed to unique immune responses that helped these individuals avoid continued illness.

The research revealed that a local immune response in the nasal lining plays a crucial role in allowing individuals to recognize and prevent SARS-CoV-2, the virus causing Covid-19, from establishing an infection.

The findings were obtained by observing immune responses before and after exposure to the virus.

The study's statement included the following insights:

“Individuals who cleared the virus immediately did not show a typical widespread immune response; instead, subtle innate immune responses occurred in the nose that had never been seen before.”

Researchers also identified that having high levels of a gene called HLA-DQA2 prior to exposure can help prevent the spread of a long-term infection.

This gene appears to play a significant role in the body's ability to fend off the virus before it can cause illness.
