Diseases are spread by viruses and bacteria.Often the diseases spread throughout a particular area and sometimes across the whole country.The diseases are transmitted in various ways.
Let’s find out what makes us ill.
Viruses:
A virus lives in a living cell inside your body and multiplies quickly. Viruses act like parasites and break down the body tissue. Viruses are much smaller than bacteria.
What are bacteria?
Bacteria are alive and are unicellular (one cell) organisms which multiply through cell division. Bacteria are important to people, especially when food is digested.
Some bacteria cause diseases because they break down body tissue or secrete toxic substances. Fortunately there are many medicines to destroy bacteria.
( run; bones and teeth; vaccinated; sweetness; rest)
Fill in the following words in the appropriate column:
Smaller; toxic substances; digestion; unicellular; fast

The virus can enter the blood in a number of ways. Here are three examples:
