Understanding COVID-19

Coronaviruses are a family of viruses causing illnesses from the common cold to severe diseases like SARS and MERS. COVID-19, a novel coronavirus, likely originated in bats and is now spreading rapidly among humans. It primarily affects the lungs, causing symptoms ranging from mild to severe, especially in older or immunocompromised individuals. The virus uses protein spikes to invade cells, leading to immune system overreaction and potential lung damage. Severe cases can result in respiratory failure and multi-organ damage. Preventive measures include hygiene practices and avoiding contact with infected individuals.

What family of viruses does COVID-19 belong to?

What is the primary function of cilia in the lungs?

• To produce mucus

• To beat mucus towards the exterior of the body

• To absorb oxygen

• To fight infections

What can result from an overactive immune response to COVID-19?

• Increased lung capacity

• Reduced inflammation

• Damage to healthy tissue

• Improved immune function

What is a cytokine storm?

• A method of virus replication

• A type of lung infection

• A large-scale inflammation in the body

• A mild immune response

What is one of the basic protocols to protect yourself from COVID-19?

• Taking antibiotics

• Regular hand washing

• Avoiding all types of food

• Staying indoors at all times

How are respiratory viruses typically transmitted?

• Through contaminated water

• Via droplets in sneezes or coughs

• Through direct skin contact

• Via insect bites
