What are the main tasks of an epidemiologist?

Epidemiologists investigate health issues such as disease outbreaks and chronic illnesses, gather and analyze data, and develop solutions and preventive measures.

What skills are important for an epidemiologist?

Analytical skills, attention to detail, and communication skills.

How do viruses differ from bacteria in terms of structure and reproduction?

Viruses are composed of genetic material enclosed in a protein coat and require a host cell to reproduce, while bacteria are unicellular organisms with their own cellular machinery for reproduction.

What role do public health organizations play in managing pandemics?

They coordinate response efforts, provide guidelines and recommendations, and support research and development of treatments and vaccines.
