Germany Sees Slight Increase in Acute Respiratory Illnesses
The Federal Ministry of Health reports a slight increase in acute respiratory illnesses (ARI) in Germany, according to its “Infectious Radar” website. The latest 7-day incidence rates (laboratory-confirmed cases per 100,000 inhabitants) are:
| Current Week | Previous Week | |
|---|---|---|
| COVID-19 | 0.5 | 0.4 |
| Influenza | 0.48 | 0.51 |
| Respiratory Syncytial Virus (RSV) | 0.11 | 0.16 |
The Robert koch Institute noted in its weekly report on acute respiratory infections that a slight increase is observed following the Easter holidays.Cold viruses, such as rhinoviruses and seasonal coronaviruses, are the primary cause of illness. Influenza viruses and RSV are occasionally detected. The number of severe cases remains low.
The National Reference Center for Influenza Viruses identified respiratory viruses in 17 of 42 samples examined (40%).Rhinoviruses were most prevalent (14%), followed by human seasonal coronaviruses (7%). Influenza A or B viruses,adenoviruses,RSV,parainfluenza viruses,and human metapneumoviruses each accounted for 5% or less. No Sars-Cov-2 or influenza C viruses were found.
WHO Member States Move Forward After Pandemic Accord Delay
After prolonged negotiations, world Health Institution (WHO) member states are proceeding with an international pandemic agreement. Implementation is expected to take several years.
Long-COVID Brain Stimulation Shows Unexpected Results
A study involving 40 Long-COVID patients experiencing meaningful cognitive fatigue explored the effects of brain stimulation. Participants received either real or sham (placebo) stimulation of the left dorsolateral prefrontal cortex, a brain region associated with attention, motivation, and drive, for 30 minutes over four days.
Both groups reported improvements in cognitive complaints up to one month after treatment, with statistically significant reductions in fatigue compared to baseline. Depressive symptoms and subjective quality of life also improved in both groups. However, no significant differences were observed between the active treatment and placebo groups.
EEG measurements revealed that only participants in the placebo group exhibited changes in brainwave patterns associated with cognitive exhaustion.
“these differences raise questions about the exact mode of action of TDCs and suggest that future studies should also examine the influence of context factors such as patient expectations or therapeutic relationship,”
the authors wrote.
Norovirus Vaccine Candidate Shows Promise in Clinical Trials
A new oral norovirus vaccine candidate, VXA-G1.1-NN, has demonstrated promising results in clinical trials. Noroviruses are a leading cause of acute gastrointestinal illness worldwide, and currently, there is no approved vaccine.
The vaccine is designed to trigger a targeted immune response in the intestine.A Phase Ib study in older adults,published in Science Translational Medicine, found the vaccine to be well-tolerated and to induce a strong, long-lasting antibody response in both blood and mucous membranes.
A subsequent Phase II study, also published in Science Translational Medicine, randomized 165 adults (ages 18-49) to receive either VXA-G1.1-NN or a placebo. Following a norovirus challenge, vaccination reduced the infection rate by 30% and considerably lowered viral load. Mucosal membrane antibodies also increased significantly, suggesting potential protective effects.
Climate Change and Unsustainable Practices Fuel Antibiotic Resistance
A study published in Nature Medicine indicates that the global burden of antibiotic resistance (AMR) could increase by up to 2.4% by 2050, even without increased antibiotic use. The analysis encompassed over 4,500 data records with 32 million samples from 101 countries between 1999 and 2022.
In 2021,resistant bacteria caused an estimated 1.14 million deaths worldwide, particularly in low- and middle-income countries. Without effective countermeasures, this number could reach almost 2 million by 2050. The United Nations aims to reduce AMR-related deaths by 10% by 2030.
Researchers suggest that current international measures, primarily focused on reducing antibiotic use, are insufficient. Model calculations indicate that under a worst-case scenario with a global temperature increase of 4 to 5°C (SSP5-8.5), the AMR load could increase by 2.4% globally, and up to 4.1% in low-income countries. Wealthier nations would see a smaller increase of 0.9%.
The study also suggests that investments in vaccination programs, improved healthcare, and expanded medical infrastructure could reduce the AMR load by 5.1% by 2050,proving more effective than solely reducing antibiotic consumption,which is projected to reduce AMR by only 2.1%.
Trachoma Cases Increasing in East Africa, India, and Somalia
Trachoma, a chronic inflammatory eye infection caused by Chlamydia trachomatis, remains a leading cause of preventable blindness. Researchers project an increase in cases to around 1.74 million by 2040 due to population growth in affected countries, according to a report in ophthalmology and Therapy.
Approximately 125 million people live in trachoma-endemic areas, with East Africa, India, and Somalia accounting for over 70% of global cases. Sub-Saharan Africa has a particularly high disease burden,with a prevalence 25 times the global average.
Despite international programs like the WHO’s Get2020 initiative,global elimination has not been achieved. Future measures should address social inequalities, particularly gender-specific risks.

- Human seasonal coronaviruses: 7%
- Influenza A or B viruses, adenoviruses, RSV, parainfluenza viruses, and human metapneumoviruses: 5% or less each
- No sars-Cov-2 or influenza C viruses were found.
Pandemic Agreement: WHO Member States Move Forward
After extended negotiations, World Health Association (WHO) member states are progressing with an international pandemic agreement. Implementation is expected to take several years.
Long-COVID: Brain Stimulation Study Shows Unexpected Results
What was the Study About?
A study assessed the effects of brain stimulation on cognitive fatigue in 40 Long-COVID patients. Participants received either real or sham (placebo) stimulation of the left dorsolateral prefrontal cortex for 30 minutes over four days.
What were the results?
Both the active treatment and placebo groups showed improvements in cognitive complaints, fatigue reductions, depressive symptoms, and subjective quality of life up to one month post-treatment. However, no important differences were observed between the groups. EEG measurements showed changes associated with cognitive exhaustion only in the placebo group.
The authors wrote: “these differences raise questions about the exact mode of action of TDCs and suggest that future studies should also examine the influence of context factors such as patient expectations or therapeutic relationship.”
Norovirus Vaccine candidate Shows Promising Results
What is Norovirus?
Noroviruses are a leading cause of acute gastrointestinal illness globally. There isn’t any approved vaccine currently.
What are the key findings for VXA-G1.1-NN?
A new oral norovirus vaccine candidate, VXA-G1.1-NN,has shown positive results in clinical trials.
- Phase Ib study: Showed the vaccine was well-tolerated in older adults and induced a strong, long-lasting antibody response in both blood and mucous membranes.
- Phase II study: reduced infection rate by 30% and considerably lowered the viral load after a norovirus challenge. Mucosal membrane antibodies also increased significantly.
Climate Change and Antibiotic Resistance: A Growing Threat
How is Antibiotic Resistance changing?
A study published in Nature Medicine indicates that antibiotic resistance (AMR) could increase by up to 2.4% globally by 2050, even without increased antibiotic use.
What are the key facts?
- In 2021, AMR caused an estimated 1.14 million deaths worldwide, particularly in low- and middle-income countries.
- Without effective countermeasures, deaths could reach almost 2 million by 2050.
- the United Nations aims to reduce AMR-related deaths by 10% by 2030.
What do researchers suggest?
Researchers suggest that current measures are insufficient. Investments in vaccination programs, improved healthcare, and expanded medical infrastructure seem more effective than reducing antibiotic use alone in curbing AMR.
- Worst-Case Scenario: With a 4-5°C global temperature increase, AMR load could increase by 2.4% globally and up to 4.1% in low-income countries.
- Effective Strategies: Investing in vaccinations, healthcare, and infrastructure could reduce AMR by 5.1% by 2050. Reducing antibiotic consumption alone would only reduce AMR by 2.1%.
