What are bacteria?
Bacteria are single-celled microorganisms that survive and multiply in many different types of environment. Some can survive in extremes of weather conditions like heat or cold. Others live in our intestines where they help digest food. Most bacteria cause no harm. However, there are exceptions. Some may cause tonsillitis, urinary tract infections, pneumonia, tuberculosis etc.
What about antibiotics in bacterial infections?
Some continue to be helpful in many bacterial infections. However indiscriminate use of antibiotics has helped create bacterial diseases that are resistant to antibiotics.
What are viruses?

A virus enters our body through various routes and takes over the cell machinery. It redirects it to produce the virus. Diseases caused by viruses include common cold, chickenpox, mumps, AIDS, COVID 19, swine flu and many more.
How do bacterial and viral infections spread?
Coming in close contact with those who have a viral infection or contact with body fluids with a viral infection can spread the infection.

Similar to bacterial infections, viral infections can spread by the bite of an infected insect or through consuming water or food that has been contaminated.
How are viral infections treated?
Some antiviral medications are available for diseases like AIDS, Chickenpox or Herpes Zoster. However, most viral infections like Ebola, coronavirus or common cold or mumps virus have no specific treatment. Treatment is focussed on relief of symptoms while the body clears the infection. In the elderly or those with diabetes, on immunosuppressants like steroids, severe cardiovascular diseases, heavy smokers or chronic alcohol consumers the ability to clear the virus from our body gets severely compromised. Drinking fluids to prevent dehydration, getting plenty of rest, using Paracetamol only to relieve aches pain and fever, throat lozenges, gargles may help.
