A team of Australian researchers has created a complex map that tracks the way in which the immune system tackles the coronavirus infection, revealing how some patients can recover.
Blood samples were collected from a volunteer patient who presented moderate symptoms related to the novel COVID-19. The blood samples were collected at four different time intervals, and the patient had been admitted into a hospital.
COVID-19 and influenza are different, but data collected from patients that have suffered from flu have been useful for the researchers. They examined the entire immune system of the patient by harnessing the experience obtained from several years of observing cases of influenza.
The population of immune cells rose exponentially after 72 hours had passed since the admission, and the mechanism has been compared to the way in which the body combats influenza during the flu season. It was theorized that the infection would pass in three days, and that is what happened.
Researchers map the way in which the immune system combats coronavirus
During the study, the team used SITREP-ID (Sentinel Travellers and Research Preparedness for Emerging Infectious Disease), a sophisticated biological sampling program that is used to minimized outbreaks of COVID-19 in the case of travelers who return to the country.
After the COVID-19 epidemic was detected, ethical and security protocols were established to observe the virus and the immune system of affected patients. Several hospitals located in Melbourne are already using SITREP-ID, and a national rollout is planned in the following weeks.
The team of researchers explored the virus during the evolution and recovery periods, obtaining valuable data that could be employed to manufacture an effective vaccine.
Current data infers that more than 80% of the COVID cases feature mild-to-moderate symptoms. By establishing an international database, the scientists could facilitate the work of several laboratories across the world. More than 200,000 cases have been diagnosed across the globe, and the number may rise soon.
