2. Viruses: Even smaller than bacteria, viruses cause a multitude of diseases ranging from the common cold to AIDS.
3. Fungi: Many skin diseases, such as ringworm and athlete’s foot, are caused by fungi.
4. Parasites: Malaria is caused by a tiny parasite that is transmitted by a mosquito bite.

Conclusion
Infectious diseases pose a significant threat to public health worldwide. Understanding the causes, transmission methods, and prevention strategies is crucial in controlling their spread. With advancements in medical science, we have been able to manage and even eradicate some infectious diseases, but new challenges continue to emerge..
