Dear MEL Topic Readers,
Vaccines alone will not stop Covid spreading – here’s why
No layer is perfectly solid to block the virus. Though vaccines are regarded as an effective weapon to protect us from the coronavirus, none of them has proved a 100% assurance, yet. Also, a vaccinated person could pass the virus on to others even though he or she might not get sick. Yes, we can track down those who have contacted closely with a positive case. But that only reduces the chance for widespread infections. Also, lockdowns, quarantines, and stay-home orders are difficult to enforce 100% coverage. And masks and face coverings alone can’t completely block virus droplets, either. What about social distancing, air ventilation, and the sunlight? They are all effective only to reduce the chances of infection, not to eliminate them. As many people do, washing hands thoroughly could kill the viruses on them but unfortunately, it won’t prevent airborne infections.
You now know none of the Covid defense methods works perfectly, just like Swiss cheese. But the more defense layers we have, the higher the chance will be to stop the virus from spreading.
Enjoy reading the infographic to learn what the Swill cheese defense model shows us.
