Infectious diseases (ID) are a subspecialty of internal medicine or general medicine. Infectious diseases are caused by microorganisms such as bacteria, fungi, viruses, or parasites. Despite the fact that the human body harbors a vast number of microorganisms, some of these organisms can cause disease under certain circumstances. There are infectious diseases that are transmitted from person to person, as well as diseases that are transmitted from animals to humans. Another method of transmission is through contaminated water and food. It is possible to treat minor cases at home by resting adequately.
Infectious Diseases Lead To severe illnesses that are caused by viral infections. They can destroy tiny blood vessel walls, rendering them leaky. The tendency of the blood to clot can also conflict with them. The resulting inner bleeding can range from relatively mild to life-threatening. Viral infections are transmitted by contact with animals, humans or insects that are infected.
There are a number of infectious diseases that can be caused by
Viral infections: There is no way for viruses to reproduce on their own since they are much smaller than your cells. In order to replicate themselves, they get inside your cells and use their machinery.
Bacterial infections: Viruses and bacteria are single-celled organisms that have their instructions encoded in DNA. There are bacteria everywhere, including on our skin and inside our bodies. There are many bacteria that are harmless or even helpful, but there are others that release toxins that can make you ill
Fungal infections:There are many different types of fungi, just as there are bacteria. Your body contains them. When your fungi get overgrown or when harmful fungi get into your body through your mouth, your nose or a cut in your skin, you can get sick.
| Bacterial Infection | Viral Infection |
|---|---|
| The bacteria that cause them are single-celled microorganisms. | Viruses are pieces of genetic material coated with proteins, such as DNA or RNA. |
| Antibiotics can sometimes be used to treat bacterial infections. | Infections caused by some viruses cannot be cured with antibiotics. |
| Examples of bacterial infections include whooping cough, strep throat, ear infection and urinary tract infection (UTI). | Examples of viral infections include the common cold and flu, most coughs and bronchitis, chickenpox, monkeypox, and HIV/AIDS. |
Viral Infection Symptoms And signs differ depending On the patient and the specific type of virus causing the infection.
