New Diseases on the Rise

In the article, New Diseases on the Rise, it states,"A new study shows that since 1940, scientists have identified 335 emerging infectious diseases in people." Back in the 1900s, people would be worried that over 300 new diseases are being discovered, but with the technology we have now, it isn't too big of a deal. Some new diseases include severe acute respiratory syndrome (SARS), Ebola, HIV (the virus that causes AIDS), West Nile virus, and methicillin-resistant staph (MRSA).

Many of the new diseases being found started in wildlife and are becoming much more common. A lot of the diseases discovered were made in Western countries, and those discoveries peaked in the 1980s. It seems like a lot of diseases to be discovered, but we are lucky we have many researchers on the job right after they are discovered.

Also, in the article, New animal-to-human diseases likely to increase, it explains that increased environmental disruptions and global warming are starting the new infectious diseases, according to a new study. 

Over 45 diseases that have passed from animals to humans have been reported in the last twenty years, and that number is suppose to rise in future years. Like I said before, we are lucky we have the technology we have today to stop it. It's weird that so many diseases and forming. People need to be more careful. 

Lastly, the last article, New Disease Discovered, talks about a specific disease and how defects are occurring in cell division. Luckily, organisms are able to repair damages on its own, even if they are serious. In this case, the damage is found and signaled to the repair system of the cell. The woman in the article was experiencing an unknown disease that scientists call "NBS-like disorder". What happens is the mutation on the disease is characterized by researchers. Although the patient can't benefit from the finding, everyone else can because researchers can find a cure.

In conclusion, its important for researchers and scientists to find new cures. It allows their jobs to be useful and to help everyone be healthy and stay alive.
