This is an anti-malarial drug, used for over 50 years in treating malaria. It was suggested that it might be effective in fighting the COVID-19 virus, a suggestion enthusiastically taken up by Donald Trump but less enthusiastically by his medical advisors who pointed out that there was no research to prove the case one way or the other.

I thought this one would come and go quickly but it lingers on. Every now and then Trump makes some new pronouncement on it that brings it into the media again.

This is a protected area within which people can travel, either from one country to another or within a small group of countries which are thought to have controlled the COVID-19 outbreak.

More of these will appear and will be warmly welcomed. The risk is always of course that the virus will reappear in which case the bubble will burst.

These are painful lesions on the toes which appear to be a symptom of the coronavirus. They range in colour from red to purple and are accompanied by a tingling, burning feeling.

There are a number of secondary effects of COVID-19 which are being reported. These are reminiscent of chilblains and just as uncomfortable, I suspect.

Contact tracing for people who test positive to SARS-COV-2 involves stepping back through a network of people to find the original source of the disease. All pathways lead to this person who is patient zero.

ZG: 7

With the possibility of clusters of infected people occurring as we ease up on restrictions, the search for patient zero in each case will become increasingly important.

The idea of the pandemic drone is not to pick out an individual but to detect a pattern within a city. Detecting a cluster of such cases can help in the fight to keep the virus at bay when some of the constraints on society are relaxed.

Another one of the hi-tech solutions to our COVID-19 problem, but not one that seems to be much in use as yet.

In the absence of any vaccine or treatment, being able to identify outbreaks of the disease and act quickly to prevent further spread is the best defence we have.

ZG: 7

We are going to need this in place very soon so there will be a lot more discussion about how it works and what kind of results it give us.

This is the habit, newly acquired for some as a result of the coronavirus lockdown, of snacking at fairly regular intervals during the day, possibly to relieve stress or boredom.

ZG: 4

While we are all aware of the increased snacking that is going on and the tendency to fatten the curve (of our stomachs), we probably think that we have more to worry about than the disapproval of dieticians.

This is the common short version of human challenge trial which could be the shortcut to testing a possible vaccine for SARS-COV-2.

ZG: 6

How to prove that a vaccine works is a bit of a problem. We are just reaching the point of human testing with a few vaccines so this is increasingly relevant.

This word dates back to a book with the title The Climate Diet: How You Can Cut Carbon, Cut Costs, and Save the Planet, written by Johnathan Henry Harrington and published in 2008. So the idea has been around for over a decade but it seems to have gained currency in the last six months or so.

ZG: 6

There is much speculation that as we emerge from COVID restrictions we may shape our world a little differently. Making our diet climate-friendly may be a one of the adjustments we could include.

One possibility for a safe return to work is to have an antibody test to confirm that someone has had asymptomatic coronavirus and is now immune to the COVID-19.

ZG: 7

It is hard to tell at this stage whether this will become a reality in relation to COVID-19.

This is a term used by spy agencies to describe the process in which politicians jump to a conclusion that they want and then ask the agencies to find the evidence for it.

ZG: 2 or 8

I give it 2 for low frequency, but it really ought to be 8 because it is something we should all watch out for, in our own and our government’s approach to life.

This is a synthetic fuel made by splitting water molecules and adding CO2 to the hydrogen using renewable energy. The process actually pulls carbon dioxide out of the atmosphere.

ZG: 5

This is still in development but if it works and allows us to fly around the world again without feeling guilty about what we are doing to the environment, then it may very well become a term that we all know.

This belongs in a set of types of virus transmission which usually balances the giver to the receiver, as in person-to-person transmission.

ZG: 7

The fear of community transmission is going to be with us for some time. This is medical jargon but we are learning a lot of that these days.
