In March 2020, the World Health Organization declared Covid-19 a global pandemic, leaving many questions unanswered about the mysterious novel coronavirus. However, over the past four years, scientists have made significant progress in understanding and unraveling some of the mysteries surrounding Covid-19.
Researchers have learned more about how the virus spreads, why it affects people differently, and the strange symptoms it can cause. Despite the popular belief that standing six feet apart is foolproof protection, scientists have made progress in understanding the dynamics of virus transmission.
One of the key findings is that Covid-19 doesn’t seem to affect children as severely as adults, primarily due to differences in immune response. The variability in experiences with Covid-19 can be attributed to the amount of virus exposure and individual immune responses.
People who are older or have underlying health conditions tend to experience more severe symptoms, as their immune systems may be weakened. However, some individuals may be able to fight off the virus before symptoms appear, or never test positive at all, due to swift immune responses.
On a positive note, vaccination has been shown to reduce the severity of illness in those who contract Covid-19. As scientists continue to make strides in understanding the virus, this progress brings hope in the fight against the global pandemic.
