Question: what is the most dangerous and common disease found in a human body?

Can I split this into two?!

The most dangerous disease is Ebola, or any of the other haemorrhagic viruses such as Lassa or Marburg. They are very contagious and difficult to treat, which makes this dangerous. The most common disease found in a human body is the common cold, which is also caused by a virus, but it is not dangerous.

If you want to know which is the most dangerous AND most common disease, most bacteria can cause infections which are common, such as Staphylococcus aureus. This can cause a simple wound infection, but this can become dangerous if it is not treated quickly enough. Wounds can become septic: this means that bacteria spread around the body and infect organs. Sepsis can be dangerous and cause death if not treated quickly.

Hope this answers your question.
