Why COVID 19 is declared as a coronavirus pandemic?
COVID 19 : coronavirus pandemic
Whats a pandemic?
Let’s break it down:
- Endemic– a disease is “endemic” if it’s restricted to a particular people or in a certain area. That level is referred to as the endemic level
- Epidemic– when this level spikes up you get an “epidemic”. An outbreak across a region, a country, or maybe even multiple countries. the Ebola outbreak in West Africa in 2013 that was an epidemic
- pandemic– when an epidemic goes global that’s “pandemic”.
COVID 19 is a whole new disease that we don’t have immunity to, it’s crossing borders and continents.
It’s spreading quickly from person to person and infecting a large number of people and in many cases, it has a high death toll.
How coronavirus pandemic happened?
Here’s the basic timeline:
- the coronavirus first appeared in China in December 2019
- by February we had a name for the virus “Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2)” and a name for the disease it caused is COVID 19
- by March there were cases of COVID 19 in every continent except for Antarctica
- We also started to see communities spread. that’s when the disease spreads to people who haven’t been to an outbreak zone
Equally important point is , the incubation period for COVID 19 can be as long as 14 days, that means it takes up to two weeks for people to show serious symptoms. Meaning people can spread the virus without even knowing it. So from one hot spot in China, we saw outbreaks popping up all across the world
China the government announced a travel lockdown across the entire country, that’s 60 million people effectively in quarantine. But even as the number of confirmed cases of COVID 19 past a hundred thousand and the death toll passed thousands; the World Health Organization didn’t declare a pandemic.
- the first is that as person-to-person transmission increases and more people get tested you’re probably going to see a jump in the number of cases
- remember there were issues getting testing kits out in the early stages, so some cases were going un-diagnosed
- a rise in confirmed cases doesn’t necessarily mean the catastrophic death toll
Don’t worry; the world is still pretty well placed to deal with this. Especially compared to the last big pandemic we faced a hundred years ago, Spanish flu. Hospitals are better prepared for coronavirus pandemic, we have technology that lets us work from home and we have grocery delivery services.
So while we don’t know what the next few months will look like, just remember to:
- Keep Calm
- wash your hands
- stay at home
