Subject:        Freedom of Information request - What group of people are
infected by and transmitting covid-19 variants, ie Delta, Omicron etc

Dear Department of Health,

I am requesting information about the spread and transmission of Covid-19
variants (eg delta, alpha, gamma, beta, omicron, etc).

I am specifically inquiring about which group of people (vaccinated or
unvaccinated) are the cause of, or are the biggest transmitter of these
variant Covid-19 strains. Hence, can you give me the number (a breakdown)
of the unvaccinated people that have been found in Hong Kong to have these
variants, compared with the number of vaccinated people that have been
found in Hong Kong to have these variants.

The reason for asking is to clarify the information coming from the local
media, which state that only vaccinated people have or are spreading the
Covid-19 variants. And therefore vaccinated people should more likely have
restrictions placed upon them as vaccinated people are actually causing
the spread and transmission of these and likely ALL future variants.

Vaccinated, in this instance, means having received either 1 or both of
the recommended covid-19 vaccines recommended or accepted by the HKGOV.

Yours faithfully,

Scott Mackenzie
