Some common viral infections are-

● Hepatitis

● COVID-19

● Chickenpox

● Measles

● Common cold

● flu

Major Differences Between Bacterial and Viral Infections

Features	Bacterial infections	Viral infections
Causes	Being caused by bacteria	Virus are the major source
Size	Large microorganism	Much smaller infection agents.
Reproduction	Tend to reproduce independently	It requires host cell to multiply
Treatment option c	Can be treated with antibiotics	Can be managed with the help of antiviral medicine
Prevention	Hygiene, vaccines, sanitation	Hygiene, vaccines, avoiding exposure

Causes of bacterial and viral infections

There can be the risk of infections due to several factors and those are-

• When there is an exposure to the infected individuals, infections surround.
• Following poor hygiene practice.
• Undertaking contaminated food and water.
• People suffering with weakened immune system
• Lack of vaccination
• Following poor sanitation
• Traveling to high-risk areas
• Living in crowded environments
• Insect or animals’ bites

• muscle ache
• skin rashes
• Diarrhea.

Symptoms which are most common among bacterial infections

• Localized pain and swelling
• Persistent high fever
• Thick yellow or green discharge.
• Common symptoms in Viral Infections are-
• runny nose
• body aches
• fatigue.

How infections spread in the body?

Bacterial and viral infections can spread through respiratory droplets either from coughing and sneezing.

● Direct physical contact

● Contaminated food and water

● Insects’ bites

● At the time of touching contaminated surface

● Animal to human transmission

Some of the risk factors

There are certain factors that can increase the susceptibility to infections:

➤ Laboratory Cultures

Samples of blood urine and even other body fluids are grown in a laboratory to identify the infectious organism.

➤ Molecular Tests (PCR)

PCR testing can help to identify the genetic material of bacteria and viruses thereby allowing the accurate diagnosis process.

Different treatment methods for bacterial and virus infection

➤ Treatment for bacterial infections
