Episode notes
Dry Air Raises Infection Risk
- Dry indoor winter air strips moisture from nasal passages, increasing infection risk.
- The nose, mouth and eyes act as primary gateways for viruses to enter the body.
How The Immune System Responds
- Viruses hijack host cells for energy, so antibiotics don't work against them.
- The immune system analyzes unknown viruses in lymph nodes, spleen or bone marrow to make antibodies.
Know Flu Transmission And Timeline
- The flu spreads via respiratory droplets and contaminated surfaces and is most contagious for about three days.
- Expect illness for three to seven days with fever, muscle aches and fatigue and plan isolation accordingly.
