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.

What's the Difference Between Viruses and Bacteria?
Characteristic Bacteria Virus
Is there a cell single cell non-cell
Structure DNA and RNA drift freely in the cytoplasm. There are cell walls and cell membranes. DNA and RNA are wrapped in a protein film.
Ribosomes Yes No
Enzymes Yes Some viruses have.
Nucleus No No
Infectious nature Local infection Systemic infection
Treatment Antibiotics Vaccines can prevent transmission, and antivirals can reduce virus replication, but can't stop its replication.
Reproduction Fission Invade and take over host cells, use host cells to replicate viral DNA / RNA, then destroy host cells and release new viruses.
Size 1000 nm
20-400 nm
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 and COVID-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.

Hunan Huateng Pharmaceutical Co., Ltd. is a leading pharmaceutical company focusing on the creation of long-acting targeted new drugs. The company has extensive experience in the development of new antiviral drugs that can treat epidemic influenza, H7N9, and H5N1 avian influenza, including OseltamivirBaloxavir Marboxil and others.
