why is difficult to treat corona virus? brief description
Answers
Viruses like novel coronavirus that causes Covid-19 are very different from other pathogens such as bacteria. Immune system finds it difficult to respond to a viral than a bacterial attack. This is why even use medicines becomes complicated in viral infection

Why is Covid-19 so difficult to treat? New study has the answer
Researchers have found why Covid-19 has become so difficult to treat and why people struggle with significant health issues months after infection.Researchers at the Trinity College Dublin showed that a comprehensive review into what we know about and the way it functions suggests the virus has a unique infectious profile, which explains why it can be so hard to treat and why some people experience so-called 'long-Covid', struggling with significant health issues months after infection.There is growing evidence that the virus infects both the upper and lower respiratory tracts - unlike 'low pathogenic' human coronavirus sub-species, which typically settle in the upper respiratory tract and cause cold-like symptoms, or 'high pathogenic' viruses such as those that cause SARS and ARDS, which typically settle in the lower respiratory tract.
Additionally, more frequent multi-organ impacts, and blood clots, and an unusual immune-inflammatory response not commonly associated with other, similar viruses, mean that Covid-19 has evolved a uniquely challenging set of characteristics.
While animal and experimental models imply an overly aggressive immune-inflammation response is a key driver, it seems things work differently in humans: although inflammation is a factor it is a unique dysregulation of the immune response that causes our bodies to mismanage the way they fight the virus.
