Difference Between Viral and Bacterial Infection As you might think, bacteria and viruses can both cause mild to serious infections. While they are different from each other. Perhaps the most important difference between bacteria and viruses is that antibiotic drugs usually kill bacteria, but they aren't effective against viruses.

By comparing the characteristics of bacteria and viruses in the above table, you can find the following difference between viruses and bacteria.

1. A bacterium is a single, but complex, cell. Viruses are smaller and are not cells.

2. Viruses reproduce by infecting a host and using the host's DNA repair and replication systems to make copies of itself, and most bacteria can live on the surface of inanimate objects.

3. Bacteria exist in intercellular organisms, and viruses are organisms that exist within cells. Viruses invade host cells and change the normal function of host cell genetic material.

4. The vast majority of bacteria are harmless to people and some strains are even beneficial, but almost all viruses are harmful.

5. Antibiotics only kill bacteria, but not viruses. Therefore, only by exploring the source of the disease and analyzing the case, can we grasp the treatment plan to benefit the patients at the first time.

What's the Difference Between Bacterial and Viral Infection?

It is important to know whether bacteria or viruses cause an infection, because the treatments differ.

Examples of bacterial infections include whooping cough, strep throat, ear infection, gonorrhea, tuberculosis, bacterial meningitis, cellulitis, Lyme disease, tetanus and urinary tract infection (UTI).

Viral infections include the common cold, flu, viral gastroenteritis, chickenpox, measles most coughs and bronchitis, HIV/AIDS andCOVID-2019.

It can be difficult to know what causes an infection because viral and bacterial infections can cause similar symptoms. Your doctor may need a sample of your urine, stool and blood for a "culture" test to have the bugs identified under a microscope.

Treatment of Bacterial and Viral Infection

Bacterial infection treatment Doctors usually treat bacterial infections with antibiotics. They either kill bacteria or stop them from multiplying.

But since antibiotic resistance is a growing problem, antibiotics may be prescribed only for serious bacterial infections.

Viral infection treatment Many viral infections resolve themselves without treatment. Other times, the treatment of a viral infection is focused on relieving symptoms rather than fighting the virus. For example, cold medicine helps relieve the pain and congestion caused by colds, but it doesn't directly affect cold viruses.

Some drugs can act directly on the virus. These are called antivirals. They work

by inhibiting the production of virus particles. Some interfere with the production of viral DNA. Others prevent viruses from entering host cells. These drugs have other ways of working. In general, taking an antiviral drug as early as possible during the first viral infection or recurring episodes is most effective.

Various antiviral drugs can be used to treat chickenpox, shingles, herpes simplex virus-1 (HSV-1), herpes simplex virus-2 (HSV-2), HIV, hepatitis B, hepatitis C, and influenza.

Viral Disease Prevention Vaccines can reduce the risk of certain viral diseases. Vaccines can be used to prevent influenza, hepatitis A, hepatitis B, chickenpox, herpes zoster (shingles), cancer-causing strains of human papillomavirus (HPV), measles/mumps/rubella (MMR), polio, rabies, rotavirus, and other viruses.
