CORONAVIRUS
Coronaviruses are a group of RNA viruses.
They cause diseases in birds and mammals, including humans. These diseases can be mild, or they can be fatal. In humans and birds, they cause respiratory tract infections. Mild illnesses in humans include some cases of the common cold . More lethal varieties can cause SARS, MERS, and COVID-19. They are enveloped viruses with a positive-sense RNA genome. The genome size of coronaviruses is about 26 to 32 kilobases, which is extraordinarily large for an RNA virus. There are four major groups of coronaviruses, called alpha, beta, gamma, and delta. The most famous coronavirus is one of the betas, the kind that causes Coronavirus disease 2019 (COVID-19) in humans. The name "coronavirus" comes from the Latin word corona, meaning "crown" or "halo", and refers to how virions look under an electron microscopy (E.M.).

In March 2020, the UK government implemented its first nationwide lockdown in a bid to contain the virus's spread. This involved closing schools, non-essential businesses, and limiting social gatherings. The lockdown measures were crucial in flattening the curve but also led to severe economic repercussions, with GDP dropping significantly and rising unemployment rates.

Throughout 2020 and 2021, vaccination efforts accelerated, with the UK becoming one of the first countries to approve a COVID-19 vaccine for emergency use. The rollout of vaccines, beginning in December 2020, was widely successful, with a large proportion of the adult population receiving their vaccinations by mid-2021. This led to a gradual easing of restrictions, allowing for a return to more normal life by summer 2021.

The emergence of new variants, including the Alpha variant, which was first identified in Kent, and Delta, which originated in India, posed additional challenges. These variants demonstrated increased transmissibility, leading to localized outbreaks and renewed concerns about hospitalizations and deaths despite the vaccination progress.

In late 2021 and early 2022, the Omicron variant emerged, causing a surge in cases but, importantly, appeared to result in milder illnesses among vaccinated individuals. This led to a reevaluation of strategies, and by early 2022, many restrictions were lifted, including mask mandates and the requirement for vaccine passports in certain venues.

As of 2023, the UK government has shifted its focus from emergency response to living with COVID-19 as an endemic virus. Vaccination programs continue, with updates for booster shots to deal with evolving variants, particularly for vulnerable populations.
