Covid 19 is a new version of the Coronavirus that has gone from animals to humans.  It is so new that scientists are still scrambling to figure out how it spreads.  The speed of how fast it is spreading and the fatality rate is still changing. How do you protect yourself from such an awful series of events?

When people who were isolated on a cruise ship were getting the virus, did they already have it, or was it being spread around by the ships’ ventilation system?  It makes you wonder.  The reason for raising the alarm is because, in churches, we share microphones, and microphones are a way to spread around harmful bacteria, common cold, and the flu.  Since Covid-19 can remain active for hours or days, depending on the type of surface it lands on, sharing a microphone can be as bad as sharing a toothbrush.

I’ve written in the past that worship leaders and pastors if they can afford it, they should own their own microphones and take personal responsibility for the cleaning and care of their microphones.  The reality, most churches can’t afford to buy microphones for every person who uses one.  With a virus that is spreading around so fast, it would be easy for a person to spray moisture onto a microphone, pass it on to another person and if that person inhales without moving the mic away, could they get the virus?  While the possibility seems remote, until we know everything about Covid-19, until there is a vaccine for it, we can still take precautions to prevent or slow down the spread.

Here is what we do know.  If you have gotten the annual flu shot, it may not protect you from Covid-19, but if you don’t have the flu or cold, if you get Covid-19, your chances of living through it is 100% unless you have other illnesses at the time you get it.  Getting the flu shot, even now, will most like you allow you to live through getting Covid-19 if you were to get it.  Cleaning hands often and not touching your face is always good advice.  Sprays or hand sanitizers with 70% alcohol will kill the virus.  Wearing a mask without goggles won’t help because the virus can enter through your eyes.

Cleaning a microphone can be an issue. How do you clean them?  One option is to do what hospitals do.  Hospitals use high levels of UV light to disinfect germs, bacteria, and viruses.  The UV light is used to kill everything contagious, including superbugs—specifically, ultraviolet light called UV-C.  There are several products available to use.  Ultraviolet can be harmful to humans if you are exposed to it too long.

The suggestion here is to make a wooden box large enough for all of the microphones and cables used during a worship service.  Line the inside of the box with tin foil, mirrors or reflective metal.  Install a UV-C light inside the box.  Generally, a 25 to 35watt lamp should do. You should also have a timer for the light.   At the end of the service, have the performers and pastor place all of their microphones and cables in the box.  Add the wireless microphones after removing the batteries as well.  If you have to handle them, wear gloves. If the pile is more than 3 cables deep, have more boxes, make a larger box or clean in batches.  Put the cables on the bottom and microphones on top. You can also put in any hearing-impaired headsets and earbuds in the box too. Anything that people share should be cleaned this way.

According to what hospitals do, they sterilize this way for 30 minutes.  The cost of making a clean box with the right type of UV lamp (UV-C) and a timer should be less than $150.00.  That is a small price to pay to keep people safe. Even if Covid-19 doesn’t come to your church, this is still a good practice to prevent colds, flues, and bacteria from giving other church members an unwanted present.

*** UPDATE ***
I’ve mentioned on other posts about using plastic food wrap or balloons over microphone capsules and windscreens. This idea only works great if the plastic is removed between the uses of a microphone. Passing microphones around is not a good idea either. If you can get a second mic, the better.
