Infectious Diseases

4. Prion disease- A prion has no genetic material and is a protein. In case the prion is abnormally folded, it impacts the brain system, which triggers dangerous diseases such as Creutzfeldt-Jakob Illness. Such diseases spread very quickly and are particularly deadly. They do not replicate in the host but stimulate anomalous behaviour in the cells of the body. A prion is basically a protein that causes no harm and contains no genetic material. Prions generally affect other parts of the nervous system. Diseases caused by Prion are rare, but in some cases, researchers have linked Alzheimer's disease to Prion disease.
5. Other Infections- Also capable of causing communicable diseases are protozoa, helminths, and ectoparasites. Protozoa are transferred via faeces contact. Protozoan causes amoebic dysentery. Helminths encompassing flatworms and roundworms also cause human infections. Ectoparasites, including mites, lice, ticks, etc. stick themselves to the skin and induce infections.

Modes Of Transmission

Infectious diseases are transmitted through the following means, such as Air: Whenever an infected person sneezes or coughs, the droplets actually contain disease-causing pathogens. For example, chickenpox and measles may spread in the air and may infect others nearby. Bodily Fluids: Pass the pathogens to a safe individual by contacting an infectious individual or their bodily fluids such as spit, vomit, sweat, urine, etc.Surface Transmission: Touching an infected individual's previously contacted objects or areas can cause the pathogen to transfer the infection to an unaffected person and cause illness.Sexual Transmission: Diseases like Syphilis and AIDS are sexually transmitted diseases

Measures to cure an infectious disease

Antibiotics are an effective medicine that can treat bacterial infections. Antibiotics generally cure urinary tract infections, renal infections, and strep throat. Antiviral medications are effective medications for treating infections like Hepatitis C, HIV, and influenza. Antifungal medications can be helpful in the treatment of valley fever, toenail infection, yeast infections, etc. Antiparasitic medications can cure infections like malaria and tapeworm.
