The number of Covid cases in the UK is once again on the rise. This is due to the emergence of new variants of the virus, which are spreading throughout the country. With summer in full swing and large gatherings such as festivals and pub visits becoming more common, doctors are warning that a potential wave of infections could occur.
In April, a group of new variants known as the FLiRT variants were identified. These variants, including KP.3, KP.2, and KP.1.1, are believed to be the main cause of the recent increase in infections in the UK. In fact, hospital admissions rose by 24% in just one week in June, with many attributing this spike to the KP.3 variant.
The KP.3 variant is a subvariant of the highly contagious Omicron strain, which, along with other variants, now accounts for over 69% of cases in the US. By June 8, KP.3 had already accounted for 33.1% of infections in the US and is now making its way to the UK. It seems that almost everyone knows someone who has recently experienced Covid symptoms, such as sore throats, headaches, persistent coughs, and fatigue.
To combat the spread of these new variants, the elderly have been encouraged to get their spring vaccinations. However, health experts are warning that the virus is constantly evolving and becoming more efficient at spreading. NHS GP Dr. Mariyam Malik explained that the FLiRT variant has specific changes in its spike protein, making it more easily transmissible and potentially able to evade immunity from previous infections or vaccinations. Similarly, the LB.1 variant also has mutations that make it more infectious and potentially reduce the protection provided by existing immunity.
Unfortunately, with the removal of legal restrictions such as social distancing and mandatory masks, viruses are now more likely to spread. This warning is echoed by many in the medical community. Virologist Professor Lawrence Young of Warwick University emphasized that the virus is still very much present and not limited to certain seasons. He believes that a combination of new, more infectious variants and waning immunity is contributing to the recent increase in cases and urges people to remain vigilant.
The UK Health Security Agency has also been closely monitoring the data on new variants and their impact on vaccine effectiveness. In May, they stated that there is currently no change to public health advice, but they are actively researching the JN.1 variant in their high containment facilities. Additionally, a recent study has suggested that Covid-19 may have originated in a lab, sparking further debate on the origin of the pandemic.
With cases on the rise, many people may be wondering about getting tested for Covid. According to Gov.UK, free rapid lateral flow or polymerase chain reaction (PCR) tests are no longer available for order online. However, they can still be purchased in shops and pharmacies, as well as online. Those with underlying health conditions or who work in healthcare may still be eligible for free lateral flow tests from a pharmacy.
As for isolation rules, there are currently no restrictions in place in the UK. However, the government still advises those who test positive for Covid to stay at home to prevent further spread of the virus. With the emergence of new variants and the constant evolution of the virus, it is important to remain cautious and follow recommended guidelines to protect ourselves and others.
