What are the different types of infection treatments?
Treatments delivered in hospitals can include things like IV fluids, electrolytes, blood transfusions, supplemental oxygen, ventilator support, and dialysis for filtering harmful molecules from the blood. The goal is to keep the patient as healthy and comfortable as possible while their body deals with the infection.
Why is it important to differentiate between bacterial and viral infections?
This is important to understand, because bacterial and viral infections must be treated differently. Misusing antibiotics to treat viral infections contributes to the problem of antibiotic resistance.
What is a viral infection?
Viral infections include the common cold, flu, most coughsand bronchitis, chickenpoxand HIV/AIDS.

Your doctor may need a sample of your urine, stool and blood for a ‘culture’ test to have the bugs identified under a microscope.
Why is treating a viral infection more difficult than treating a bacterial infection?
Curing a viral infection Antibiotics are useless against viral infections. This is because viruses are so simple that they use their host cells to perform their activities for them. So antiviral drugs work differently to antibiotics, by interfering with the viral enzymes instead.

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

This is dangerous because over-prescribing antibiotics can lead to antibiotic resistance. Antibiotic resistance occurs when bacteria adapt to be able to resist certain antibiotics.
What is antibiotic resistance?
Antibiotic resistance occurs when bacteria adapt to be able to resist certain antibiotics. It can make many bacterial infections more difficult to treat. If you’re prescribed antibiotics for a bacterial infection, take your entire course of antibiotics — even if you begin to feel better after a couple of days.
How can bacteria be transmitted?
In addition to being transmitted from person to person, bacterial infections can also be transmitted through the bite of an infected insect. Additionally, consuming contaminated food or water can also lead to an infection.

Can antibiotics kill bacteria?
Doctors usually treat bacterial infections with antibiotics. They either kill bacteria or stop them multiplying. But since antibiotic resistance is a growing problem, antibiotics may be prescribed only for serious bacterial infections.
Target: Virus
Most antiviral drugs prevent infected cells from making more viruses. They work by disrupting an essential step in the viral replication cycle. A few antiviral drugs block viruses from getting into cells.
Target: The Immune System
The immune system is complicated. It’s made up of organs, cells, and molecules both large and small. Signaling molecules released from the site of infection travel in the bloodstream and throughout the body, with widespread effects. Yet scientists have learned a lot about how the immune system works.
Target: Symptoms
Another category of treatments is aimed at relieving symptoms while the immune system works on clearing the virus. This category is very broad. It includes home remedies, medical interventions that are usually delivered at hospitals, and emotional support. Some of these treatments are directed at the specific effects of a virus.

Drinking water or receiving intravenous fluids to stay hydrated. Getting plenty of rest to help the body fight the virus.
How do antiviral medications affect the immune system?
Antiviral medications reduce the ability of the virus to multiply and spread through the body. Reducing an overactive immune response. In patients with severe COVID-19, the body’s immune system may overreact to the threat of the virus, worsening the disease. This can cause damage to the body’s organs and tissues.
