The drop in vaccination rates is believed to be driving a surge in measles cases in England, mainly in the West Midlands. As of 18 January, 216 confirmed cases and 103 probable cases have been reported in the region since 1 October 2023, the UK Health Security Agency (UKHSA) revealed. The majority of cases (around 80 per cent) were from Birmingham, with children aged under 10 years being infected the most. UKHSA Chief Executive, Professor Dame Jenny Harries has warned that the outbreak could spread further to other towns and cities if urgent action is not taken to increase Measles, Mumps and Rubella (MMR) vaccination uptake in areas at greatest risk.

Proposed changes to a European Union pharmaceuticals law will include stronger obligations for the supply of medicines and earlier notifications of shortages, EU Health Commissioner Stella Kyriakides said last week (January 17). Kyriakides told a session of the European Parliament that shortages of antibiotics are a growing problem for many European countries. She said the European Commission's proposal to revise the pharmaceuticals legislation is planned for March. "Our objective is and remains to secure access to medicines for all patients in need and to avoid any market disruption of medicines in the EU," Kyriakides said. Shortages of antibiotics have been reported in 26 European countries, the European Medicines Agency says. The unseasonably early upsurge in respiratory infections in Europe this winter and insufficient production capacity are the root causes of the shortages, Kyriakides said. Numerous EU lawmakers speaking at the session said the shortages needed to be tackled urgently. But experts say shortages of essential generic medicines like antibiotics are likely to be recurrent in Europe due to problems in the sector such as the gradual migration of generic manufacturing to Asia.

The UK Health Security Agency (UKHSA) has published the latest national surveillance data on antibiotic prescribing and resistance. The English surveillance programme for antimicrobial utilisation and resistance (ESPAUR) report showed an increase in antibiotic use in all settings (apart from dental) in 2022. According to the report, antibiotic prescribing rose by 8.4 per cent in 2022 compared with 2021, although the number remains below 2019 pre-pandemic levels. "There are many reasons behind the increase in prescribing, one of which is likely related to decreased immunity and exposure to infections during the COVID-19 pandemic that may have underpinned the increased transmission in co-circulating infections, namely: influenza (flu), respiratory syncytial virus (RSV) and group A streptococcus (GAS)," the report stated.

A new study has revealed that the risk of death from COVID-19 decreases significantly after vaccination, but this protection diminishes after six months, providing evidence for continued booster doses. Researchers from the UK Health Security Agency (UKHSA), who analysed more than 10 million cases of COVID-19 in adults in England between May 2020 and February 2022, found a clear association between vaccination and reduced mortality. But they also highlighted a crucial timeframe - within six months of the last vaccine dose - when Case Fatality Risk (CFR) - the proportion of cases that resulted in death - was consistently at its lowest across all age groups. After this, the protective benefit of the vaccine began to wane and CFR increased.

The UK Health Security Agency (UKHSA) has raised alarm over rising cases of extensively antibiotic-resistant Shigella infections, mainly in gay, bisexual, and other men who have physical relationship with men (GBMSM). There has been a 53 per cent increase in cases since the beginning of 2023, mostly driven by a cluster of antibiotic resistant strain called Shigella sonnei, with 97 cases reported this year until November, compared to just four cases last year. According to UKHSA, Shigella sonnei infections are difficult to treat as the strain does not respond to the antibiotics typically used to treat the bacteria. While it has been found across England, cases are concentrated in London (45), the North West (21) and South East (12). Shigella is an infectious gut infection that can cause symptoms like diarrhoea (sometimes mixed with blood), stomach cramps and fever, which are commonly mistaken for food poisoning.

People who test positive for Covid-19 on rapid lateral flow tests will not need to confirm their results with a follow-up PCR test if they are not showing symptoms, the UK Health Security Agency said on Wednesday (January 5). Britain is reporting record daily case numbers, and the UKHSA said that the high prevalence meant the chance of a false positive from a lateral flow device (LFD) was low. The move could also reduce the burden on the testing system, and reduce confusion if the test results contradict each other. At current levels of prevalence, officials say a positive LFD result is likely to be accurate, even if a follow-up PCR were negative. "While cases of Covid continue to rise, this tried-and-tested approach means that LFDs can be used confidently to indicate Covid-19 infection without the need for PCR confirmation," said UKHSA chief executive Dr Jenny Harries.

The UK Health Security Agency (UKHSA) has suggested that the Live Attenuated Influenza Vaccine (LAIV) vaccine that offers protection to children against flu may also help reduce the rate of group A strep infections. LAIV is a nasal spray offered each season to most children aged 2 and 3 years old, and to school-aged children, to help protect against flu. The new study looked back at data from 2013 to 2017, comparing rates of group A strep (GAS) infections in pilot areas and comparing them to other areas where the vaccine was not being offered as widely. It was found that incidence of GAS was lower in pilot areas where the LAIV vaccine was being offered to all primary school children, compared to areas where it was being incrementally rolled out. The study revealed, in 2 to 4 year olds, rates of GAS were 73.5 per 100,000 children in pilot areas, compared to 93 per 100,000 children in non-pilot areas. In 5 to 10 year olds, rates of GAS were 50.3 per 100,000 children in pilot areas, compared to 57.8 per 100,000 in non-pilot areas.

Genomic sequencing allowed the world to track new coronavirus variants throughout the pandemic. Now British researchers plan to use it to better understand a host of other respiratory pathogens, from influenza to respiratory syncytial virus (RSV). The work is aimed at shedding more light on known threats and, potentially, emerging ones, the team at the Wellcome Sanger Institute, working with the UK Health Security Agency, said. The world has never had access to the kind of real-time information for these viruses that scientists obtained on SARS-CoV-2 through sequencing millions of genomes, Ewan Harrison, head of the new Respiratory Virus and Microbiome Initiative, told reporters on Monday. That includes granular detail on how they transmit as well as how they evolve in the face of the human immune response. "We hope that by expanding our ability to sequence these viruses routinely, we can build upon the work that's going on COVID, and hopefully supercharge research efforts to understand the transmission of these viruses, but also to help develop new treatments and vaccines," Harrison said.

With scarlet fever currently circulating in England, the UK Health Security Agency (UKSHA) has urged parents to remain vigilant for potential symptoms in children. Also known as scarlatina, it is an infectious disease triggered by group A strep bacteria that can lead to symptoms such as fever, a sandpapery rash, sore throat and swollen tonsils. The latest data published by the UKHSA showed that a total of 19,528 cases of scarlet fever were reported in the 2023/24 season, of which 12,176 cases occurring between 1 January and 24 March 2024. While the number of cases recorded this year is lower than those recorded during the same period in 2023, which totaled 15,933 cases, it exceeds the average for the previous five years. "Scarlet fever is a common childhood illness, although it can affect anyone of any age," said Dr Theresa Lamagni at UKHSA. Parents are advised to contact their GP practice or NHS111 when their GP is unavailable, if they suspect they or their child are experiencing symptoms of scarlet fever.
