#Ichallengeyou #Science 6.What is virus?

In this living world of humans, animals and plants there are many more living species that are very small in size. For example insects that are very small and sometimes can be crushed under our feet too like ants, spiders or flies. But there are some other living beings also who are so tiny in size that we can not even see them with naked eyes and we need microscope to see them. These very small living creatures are called "Micro organisams" and they also have a variety of species. We can divide them into:

Bacteria, Fungi and Virus.

Virus itself not a living creature but for wonder it acts like a living cell when it enters into a living body or cell of humans, animals or plants. They grow and replicate there while inside a body and if remain outside they act like a non living thing. They create infections inside the body and because of these infections we suffer from so many diseases. Some of the virus disease are curable but some not. I'll show you some of the diseases in humans which are caused from viruses and that are:

1.Influenza, Measles, Mumps and Rubella and they all can be carried by some reservoirs like birds, insects or flies. But these are curable diseases and have vaccines too.
