   DIFFERENCE  BETWEEN  BACTERIA  AND VIRUSES

There are two common causes of disease in human being .

1. Bacteria

2.Viruses

Bacteria are single celled living organisms . Most bacteria are not harmful but small percentage of bacteria are harmfull and causes disease. Humans have trillions of bacteria in and on our bodies. Most of them are usefull for our bodily functions . Normally bacterial infections are limited to one part of our body like ear infection, throat infection  etc. Antibiotics  stops or slow downs the spread of bacteria.

Viruses are not considered living organisms in nature that means they need a live host in order to survive.They infect the cells of living being , including  humans. Most viruses are very harmful but some can be beneficial.Once we come in contact with viruses , they attacks healthy cells in our body , taking them over to reproduce and they spread throughout our body. Coronavirus or COVID-19 is 

one of them , it is caused by the SARS-Co-2 virus.

 Symptoms of this virus is fever , cough and shortness of breath.

Bacteria and viruses both are susceptible to hand soap and sanitizers. It is found that proper hand washing ( around 20 sec and more ) kills and removes the bacteria and viruses from our skin. 

 So we should wash our hands frequently after touching  communal surfaces such as elevator buttons , ATMs etc.

In addition to this try to avoid touching our face  frequently , covering coughs and sneezes is also very important.We can Prevent

the spread of both bacteria and viruse by proper practising good hygiene.

If we are sick stay at home, try to be away from the others to avoid the spread of viruses or bacteria . Get quarantine by him self.

However  Healthy people can over come the  infections fast but  elderly people over 60 years of age and childrens are at high risk for developing complications from these infections.
