However, they later held that the new strain was responsible for the rise in infections. The new strain came to light in December but the samples in which it was found were collected in September. This led to the UK government announcing a strict Tier 4 lockdown in some parts of the UK, where the new strain was more frequently being detected than other parts of the country. Stricter curbs imposed in the UK Under the new restrictions, non-essential services and retail outlets have been ordered to shut down, curb on social gatherings has been imposed, and people have been advised to stay at home at all time unless absolutely necessary. UK Prime Minister Boris Johnson, his Chief Medical Officer Chris Whitty, Chief Scientific Advisor Sir Patrick Vallance, and the Cabinet agreed that the new strain of the COVID-19 has changed the current landscape, and a lockdown was deemed necessory to contain the spread of the virus and protect lives. It is not clear at the moment whether the new strain is also responsible for the higher mortality rate.
