Pathogen
A disease causing agent
A pathogen is any type of microorganism, such as bacteria, viruses, fungi, or parasites, that can cause disease in plants, animals, or humans. Pathogens are living organisms that are capable of reproducing and infecting other organisms. They can enter the body through various routes, such as through the air, water, or through contact with an infected person or contaminated object.
Once a pathogen enters the body, it can cause a range of symptoms depending on the type and severity of the infection. For example, some infections may only cause mild symptoms like a runny nose or a sore throat, while others can be life-threatening.
To prevent and control the spread of pathogens, it is important to maintain good hygiene practices such as washing hands regularly, covering your mouth and nose when you cough or sneeze, and staying home if you are sick. Vaccinations and antibiotics are also commonly used to prevent or treat infections caused by pathogens.
