What is the difference between bacterial and viral infections?

Answer 1

Viral : Most viral infections stay only up to 10 days.

Bacterial : Bacterial infections stay more than two weeks.

Viral : Viral infection causes runny nose, pain in body, weakness, recurrent fever.

Bacterial : Bacterial infections cause thick and coloured nose, high fever, chronic cough.

Viral : Most viral infections can be cured without antibiotics and only with some light medicines of pain and fever as prescribed by the doctor.

Bacterial : Bacterial infections always require antibiotics depending on the condition of the patient's resistance (Immunity) against antibiotics.

Viral : Viral infections are easy to pass by the patient. Mostly it do not disturbed the normal routine life.

Bacterial : Bacterial infections are hard to suffer. Patient is sometimes not able to drink even a glass of water.

As you might think, bacterial infections are caused by bacteria and viral infections are caused by viruses. Infections caused by bacteria include strep throat, tuberculosis and urinary tract infections. Diseases that result from viruses include chickenpox, AIDS and the common cold.

Bacteria are single-celled microorganisms that thrive in many different types of environments. Some varieties live in extremes of cold or heat, while others make their home in people's intestines, where they help digest food. Most bacteria cause no harm to people.

Viruses are even smaller than bacteria and require living hosts - such as people, plants or animals - to multiply. Otherwise, they can't survive. When a virus enters your body, it invades some of your cells and takes over the cell machinery, redirecting it to produce the virus.

Perhaps the most important distinction between bacteria and viruses is that antibiotic drugs usually kill bacteria, but they aren't effective against viruses. In some cases, it may be difficult to determine whether a bacterium or a virus is causing your symptoms. Many ailments - such as pneumonia, meningitis and diarrhea - can be caused by either type of microbe.

Inappropriate use of antibiotics has helped create strains of bacterial disease that are resistant to treatment with different types of antibiotic medications.
Bacterial infections are caused by bacteria and Viral infections are caused by Viruses. Unlike bacteria, Viruses need a host to survive, so viruses latch on to a body's cell, and inject their genetic code inside of it. Then that body cell send out more virus-infected cells. Which leads on to producing more and more virus cells. Bacteria on the other hand are their own cell, and do not need a host. They occur by a bacteria entering the body, and not getting defeated by the immune system's Killer T cells, which destroy bacteria. Your immune system has cells called "B cells," Some of those B cells make antibodies when they come in contact with a virus, bacterial infections occur when a B cell comes in contact with a bacteria it doesn't recognize, and by the time your B cells start producing antibodies for the bacteria, you're already sick.
