Lather your hands by rubbing them together with the soap. Be sure to lather the backs of your hands, between your fingers, and under your nails. Scrub your hands for at least 20 seconds. Need a timer? Hum the “Happy Birthday” song from beginning to end twice.
Many stores have long since sold out of hand sanitizer in the US and washing your hands is a better move anyway, but if you’d like to have some sanitizer on hand for when you can’t get to a sink, the World Health Organization has you covered. The WHO recipe is for making 10-liter batchs, so Popular Science helpfully scaled it down to a more reasonable size:
1 cup 99% isopropyl alcohol
1 tablespoon 3% hydrogen peroxide
1 teaspoon 98% glycerin/glycerol
1/4 cup, 1 tablespoon, and 1 teaspoon sterile distilled or boiled cold water
To the alcohol, add the hydrogen peroxide & glycerin and stir or shake if you’re mixing in a container with a lid. Then add the water.
For COVID-19 prevention, the CDC recommends a hand sanitizer that contains at least 60% alcohol; this recipe will end up being about 75% alcohol. The Popular Science piece also includes another recipe for a hand sanitizing gel that’s much closer to store-bought gels that involves mixing isopropyl alcohol, aloe vera gel, and tea tree oil. They also note that vodka does not contain enough alcohol to meet the CDC’s recommendation, especially when mixed with the other ingredients.
In a media briefing that’s still ongoing as I’m writing this, Dr. Tedros Adhanom Ghebreyesus, the Director General of the World Health Organization, has officially characterized the COVID-19 outbreak as a pandemic. A pandemic is defined as:
An influenza pandemic is a global epidemic caused by a new influenza virus to which there is little or no pre-existing immunity in the human population. Influenza pandemics are impossible to predict; and they may be mild, or cause severe disease or death. Severe disease may occur in certain risk groups, which may correspond to those at risk of severe disease due to seasonal influenza.
WHO has been assessing this outbreak around the clock and we are deeply concerned both by the alarming levels of spread and severity, and by the alarming levels of inaction.
We have therefore made the assessment that COVID-19 can be characterized as a pandemic.
Pandemic is not a word to use lightly or carelessly. It is a word that, if misused, can cause unreasonable fear, or unjustified acceptance that the fight is over, leading to unnecessary suffering and death.
Describing the situation as a pandemic does not change WHO’s assessment of the threat posed by this virus. It doesn’t change what WHO is doing, and it doesn’t change what countries should do.
Progress on fighting COVID-19 can be made everywhere when the right steps are taken:
If countries detect, test, treat, isolate, trace, and mobilize their people in the response, those with a handful of cases can prevent those cases becoming clusters, and those clusters becoming community transmission.
Even those countries with community transmission or large clusters can turn the tide on this virus.
Several countries have demonstrated that this virus can be suppressed and controlled.
The challenge for many countries who are now dealing with large clusters or community transmission is not whether they can do the same — it’s whether they will.
But WHO also acknowledges how disruptive the pandemic can be:
We are grateful for the measures being taken in Iran, Italy and the Republic of Korea to slow the virus and control their epidemics.
We know that these measures are taking a heavy toll on societies and economies, just as they did in China.
All countries must strike a fine balance between protecting health, minimizing economic and social disruption, and respecting human rights.
And in closing he deflects attention from the word “pandemic”:
Let me give you some other words that matter much more, and that are much more actionable.
Prevention.
Preparedness.
Public health.
Political leadership.
And most of all, people.
We’re in this together, to do the right things with calm and protect the citizens of the world. It’s doable.
Can we out-collaborate a pandemic? Alex Steffen challenges the blogosphere to sound the alarm about the avian flu. The WHO says: “never before [has] any avian influenza virus caused such extremely high fatality in humans”.
