How do you tell if it's viral or bacterial?

What are 3 differences between viruses and bacteria?

Bacteria are single-celled, living organisms. They have a cell wall and all the components necessary to survive and reproduce, although some may derive energy from other sources. Viruses are not considered to be “living” because they require a host cell to survive long-term, for energy, and to reproduce.

How do you identify a viral infection?

The traditional approaches to laboratory diagnosis of viral infections have been (1) direct detection in patient material of virions, viral antigens, or viral nucleic acids, (2) isolation of virus in cultured cells, followed by identification of the isolate, and (3) detection and measurement of antibodies in the ...

How do I know if my cough is viral or bacterial?

In addition to lab tests, sputum or mucus from a cough can be visually examined to determine whether bronchitis is viral, bacterial, or both. Clear or white mucus often indicates a viral infection, while yellow or green mucus may suggest a bacterial infection.

Currently, nucleic-acid detection and immunoassay methods are among the most popular means for quickly identifying viral infection directly from source. Nucleic acid-based detection generally offers high sensitivity, but can be time-consuming, costly, and require trained staff.

What is the most common method used to identify viruses?

PCR is one of the most widely used laboratory methods for detection of viral nucleic acids.

How does your body defend itself against viruses and bacteria?

Your immune system steps in, like a bouncer who means business. It releases white blood cells and other chemicals that destroy these threats. Or it causes a reaction, like a sneeze, to boot out a virus in your nose. It's an elite squad of agents that zap invaders -- like bacteria, viruses, and fungi -- ASAP.
