Viruses that cause the common cold, which is an upper respiratory tract infection. Replicate optimally at 33 degrees Celsius. They can exacerbate lower respiratory tract illnesses.

Ranges from mild respiratory illnesses to severe systemic illnesses.
Illness severity is determined by the host's immune response and the virus' ability to dysregulate it, leading to significant inflammation in organ systems.
Scientific understanding of COVID-19 is rapidly evolving.

Two important zoonoses:
– SARS and MERS, which are systemic infections.
– These coronaviruses replicate optimally at 37 degrees Celsius, the temperature of the body core.
– In the image, highlight the club-shaped spikes that form the characteristic "corona" around the virus particle.
