Helpful tips for SARS-CoV-2/COVID-19
Hello everyone,
I was seriously not expecting having many followers for a shared liking of the blessing that is Gakuen Babysitters. Though I am confident that many of you already know how to deal with the pandemic that is COVID-19 (in spite of the US government’s ineptitude), I thought that I as a now-pharmacy student should share some info to provide reassurance for everyone’s health and safety.
1. Washing hands for at least 20 seconds is the best way to remove bacteria and viruses from the hands. The reason why this works is because most viruses are shaped like a ball with protein “spikes”, and the coating of the virus is a lipid/fat layer. Soap molecules have a lipophilic/hydrophobic (fat-loving) tails that help dissolve the lipid layer of viruses to then break the virus open, essentially deactivating the virus. The diagrams below shows how soap works and how to effectively wash hands.
2. If soap and water is not available at the moment, hand sanitizer that has at least 60% alcohol (ethanol/EtOH or isopropyl alcohol/IPA) is sufficient in deactivating viruses and killing bacteria on the hands and skin (though obviously it is not recommended to apply it on the face especially near the eyes). Though more alcohol is better, the final concentration should not reach above 90% because higher concentrations can cause the viruses’ and bacteria’s extracellular proteins to coagulate and create another layer of protection for the microbes (definitely something that we DON’T want). Water within the solution also helps catalyze the reaction that the alcohol does in dissolving the lipid layer and denaturing the proteins of microbes (source). My mother, bless her soul, gave me some handmade hand sanitizer, however the recipe she used did not have the sufficient alcohol concentration in the END PRODUCT (as one of the ingredients used was 70% IPA instead of 99% IPA). A simple recipe of 2/3 cup of 99% medical-grade IPA mixed with 1/3 cup of aloe vera gel would yield an effective hand sanitizer that has 66% IPA. This website is helpful to figure out other combinations to make sufficient hand sanitizer. It should also be noted to beware of shops that are price-gouging ingredients like medical grade IPA, which is obviously reprehensible.
3. Wearing masks is important to help limit the spread of COVID-19 via respiratory droplets as there are many people that could have the virus but be asymptomatic. While the CDC was being a little wishy-washy with their stances on masks, there is a reason why wearing masks is now highly recommended. While I do not know if there are more recent studies about COVID-19 and masks, this study linked here does provide some clarity for the recommendation. To summarize, despite that facial coverings do not completely filter out the virus of the COVID-19 patients’ cough, the viral spread (shown as viral load in log values) of patients who had facial coverings is less than that of those who did not.
Surprisingly, to me at least, the patients who had the double-layered cotton mask had an even lower viral load than with the surgical mask. It is important to note however that the virus is still detectable from the outside of the masks. This is why one should not touch their face often to adjust the mask, as uncomfortable as they are. I also recommend recycling the masks by washing with soap/laundry detergent and warm-to-hot water to then hang them to dry. The sample size of the study is pretty small of n=4 so take it as you will, and there are quite a few criticisms of the study that I agree with.

I hope you all stay safe and practice social distancing! :)
