Two types of an infecting microorganism or agent are rife at the moment.
Firstly: Authorities are alarmed by an emerging spread of measles in England.
Measles is often associated with being a disease of the past and as a result people may be unaware that it is dangerous infection that can lead to death in severe cases. Before measles vaccine, nearly all children got measles by the time they were 15 years of age.
The infectious period is from around four days before the appearance of a red-brown rash, to around four days after its appearance. In addition, abdominal symptoms may include nausea and vomiting, abdominal pain and diarrhea. Symptoms usually last about 14 days in all.
One of the earliest written descriptions of measles as a disease was provided by an Arab physician in the 9th century. In 1757, a Scottish physician discovered measles to be caused by an infectious agent present in the blood of patients. In 1954 the virus that causes measles was isolated in Boston, Massachusetts.
I read another news item this morning. Children are playing God by spreading a virus over the internet. Children as young as 11 years old are writing malicious computer codes to hack into accounts on gaming sites and social networks. We teach children they can't take someone else's toy, or steal one from a shop, so schools need to teach them the same message when writing software.
Everyone should be protecting their computer in the same way as a vaccination is used to prevent measles.
