Are you coming from using SQL Server Management Studio on a PC?
If yes, you may be better off using something like PostgreSQL on Mac OS X, and a PostgreSQL GUI browser tool, because it may be harder to use SQLite in this situation as you don't have the benefit of using a computer language to make up for the datatypes that SQLite does not have.
For example SQLite does not have a DateTime datatype. If you need to do a lot of date/time field manipulation in SQLite, this can be made easier when using a programming language like C#, because you can use a SQLite integer datatype to store the DateTime data, and then convert the integer to a C# DateTime datatype and do the DateTime manipulation in C#. But if you aren't a coder, then this option isn't available to you, and you will have to have other ways to manipulate DateTime data in SQLite like using the string datatype to store the date time values and then use corresponding SQL queries to handle the "DateTime stored as a string" situation.
He says that they are contagious, but he doesn't say highly contagious (I know you're not the one who made that claim, I just wanted to clarify). I'm not sure if we know yet how contagious people without symptoms are, but it's most likely going to be less than a person with symptoms simply because they're no longer coughing.
You may also need the SQLite command-line tools from the SQLite website; https://www.sqlite.org/download.html
