I do not have any specific information about Dr. Jamie Lopez Bernal or the exact context of the quote you mentioned. However, I can provide a general interpretation based on the statement.
When Dr. Jamie Lopez Bernal says, "Covid-19 cases and hospital admission rates remain at low levels, though have risen very slightly in the past two weeks," it means the following:
Covid-19 cases: The number of people testing positive for Covid-19 is relatively low.
Hospital admission rates: The rate at which people with Covid-19 are being admitted to hospitals is also at a low level.
The recent trend: In the past two weeks before the statement, there has been a slight increase in both Covid-19 cases and hospital admission rates.
It's important to note that "low levels" are relative and can vary depending on the region, country, or specific context being referred to. A slight rise in cases and hospital admissions, even if the overall numbers are still low, can be concerning for public health officials because it might indicate the start of a potential increase in Covid-19 transmission.
Public health authorities closely monitor these trends to make informed decisions about implementing or easing restrictions, promoting vaccination campaigns, and taking other measures to control the spread of the virus and protect public health.
