COVID-19 2
Flying Doctors Korea Crisis Education - COVID-19 #Response Methods Next, we will briefly explain the response methods
If you suspect that you have been infected with COVID-19 or have received a confirmed diagnosis,
isolation is the most important aspect
#Response Methods - Hydration and Nutrition Next, it is important to pay attention to hydration and nutrition
(10% increase in fluid intake when body temperature increases by 1 degree Celsius from normal) In the case of fluid intake, if our body temperature increases by 1 degree Celsius from normal,
fluid consumption increases by 10%, so if we consume fluids as usual when we have a fever,
dehydration symptoms inevitably occur
Dehydration symptoms are actually very dangerous
Next, nutrition intake is important
If we do not properly intake nutrients, we will not have the energy to overcome the stress of infection
(The regeneration time of intestinal epithelial cells is long, which prolongs the recovery period of the disease) When diarrhea or vomiting occurs, the regeneration time of intestinal epithelial cells is long
Which will prolong the recovery period of the disease
Therefore, you should pay strong attention to your intake of fluids and nutrients
#Response - Taking fever reducers Taking fever reducers is important, and when it comes to fever reducers, there is ibuprofen, or Advil in other countries
In Korea, there is Carol and so on
If you don't have acetaminophen like Tylenol, you can take aspirin
Because, as explained earlier, if the fever persists, you become vulnerable to dehydration
When we have pain, fever, or feel unwell
It causes stress and that can also weaken the immune system
Therefore, it is important to take sufficient fever and pain relievers
#Response - Dealing with shortness of breath, chest pain, and decreased urine output If you have any of these three symptoms, you should definitely go to the hospital
Typical symptoms would be shortness of breath, chest pain, and decreased urine output
#Response - Dealing with shortness of breath Shortness of breath is a very subjective symptom
For example, I may not have been out of breath climbing two flights of stairs before
But suddenly, I find myself out of breath after walking just a little, or even after climbing just one flight of stairs
If you experience difficulty breathing, you need to go to the hospital
And if you have come down with a lung disease or, although rare, myocarditis or myocardial infarction, chest pain may accompany it
In such cases, you must go to the hospital and see a doctor
#Response method - Decreased urine volume. If dehydration has progressed or there is kidney damage due to medication, urine volume may decrease
When you have these three symptoms, it's best to go to the hospital as soon as possible
#Routes of Transmission Next, let me briefly explain about the routes of transmission
We need to know the routes of transmission of COVID-19 to know how to defend against it
Size comparison (Coronavirus: 0.1㎛ / Droplets (mucus): 5㎛ or more → up to 8m) The coronavirus is about 0.1㎛ in size
If converted to meters, it is one ten millionth of a meter, it is a very small virus
The most common route of transmission for the coronavirus is through droplets, also known a drops of saliva
Droplets is defined as saliva drops that are 5㎛ or larger
When speaking or breathing quietly like me, it only goes up to a radius of 2 meters and falls to the ground due to gravity
However, if you shout, sneeze, cough, or sing,
It is known that these droplets can spread up to a maximum of 8 meters
However, as these droplets fly, the moisture evaporates
As a result, the droplets become smaller and lighter, and when they become smaller than 5㎛,
(Aerosol: 5㎛ (0.6~0.8㎛) → floats in the air for more than 16 hours) This changes from droplets to aerosols
Aerosols are lightweight and can float in the air for more than 16 hours without being affected by gravity
Aerosols can also spread throughout a building through the air conditioning system
They can also be present in the space we are in without being visible
These droplets and aerosols can spread not only in the immediate vicinity
But can also travel far and act as a source of contact transmission
That's why we need to understand why wearing a mask and washing hands are important
For example, aerosols can be as small as 0.6 micrometers
So, we need to know the performance of the masks we are using
For example, an N95 mask filters out 95% of particles as small as 0.3 micrometers
A KF94 mask can block 94% of particles as small as 0.4 micrometers
And a KF80 mask, commonly known as dental mask, can block 80% of particles as small as 0.6 micrometers
Surgical and regular masks can filter out particles as large as 3 micrometers, but the percentage is not specified
Hand washing is important because droplets and aerosols can spread far and wide
(Fomites) non-living contact infection agent -> Wash hands, disinfect, eat cooked food) There could be viruses on any object around us
Therefore, washing hands is very important, disinfection is important, and eating cooked food is important
