A seroepidemiological survey of 801 local residents from 28 villages was conducted to assess the seroprevalence of Lyme disease and to identify the risk factors of becoming seropositive for Lyme disease in the northern suburb of Beijing. Forty-one serum samples were positive for IgG against B burgdorferi and the seroprevalence was 5.1% (41/801), indicating that Lyme disease is endemic in the rural population. In the multivariable analysis, sowing and harvesting in summer (OR, 2.377, 95% CI, 1.233-4.583), weed in the yard (OR, 1.914, 95% CI, 1.003-3.655) were positively associated with Lyme disease, while wearing protective clothes (OR, 0.173, 95% CI, 0.041-0.732) was negatively associated with Lyme disease. People living in the area are easily infected just near the house or in the cropland. They were barely diagnosed and cured. Without clear tick knowledge, the people are at high risk of exposure to tick bite and Lyme disease.

Background/objectives: Lyme disease (LD) is a major public health problem in Europe and the United States, with increasing incidence and not many prevention options. Vaccine hesitancy might be a significant barrier to successful vaccination campaigns having in mind previous vaccine development failures. This study aimed to evaluate the public's perception of LD vaccination in Poland, assess willingness to vaccinate, and identify factors influencing vaccination attitudes.

Favorable Nonclinical Safety Profile of RSVpreF Bivalent Vaccine in Rats and Rabbits.

Vaccines (Basel)

December 2024

Drug Safety Research and Development, Pfizer Research & Development, Pearl River, NY 10965, USA.

: Respiratory syncytial virus (RSV) infections usually cause mild, cold-like symptoms in most people, but are a leading infectious disease causing infant death and hospitalization and can result in increased morbidity and mortality in older adults and at-risk individuals. Pfizer has developed Abrysvo, an unadjuvanted bivalent recombinant protein subunit vaccine containing prefusion-stabilized fusion (F) proteins representing RSV A and RSV B subgroups (RSVpreF). It is the only RSV vaccine approved for both maternal immunization to protect infants and active immunization of older adults (≥60 years) and 18-59-year-old individuals with high-risk conditions for prevention of RSV disease.

The causative agent of Lyme disease, , is endemic to Canada, the northeastern United States, northern California, and temperate European regions. It is rarely associated with a travel-related exposure. In this report, we describe a resident of southern Ontario, Canada who developed rash, fever, and cranial nerve VII and XII palsies following a 12 day trip to Ecuador and the Galapagos islands approximately four weeks prior to referral to our center.

Lyme carditis is an uncommon but potentially fatal manifestation of early disseminated Lyme disease. Timely diagnosis poses a clinical challenge due to the highly variable and non-specific symptomatology that can be easily overlooked, as well as the limited availability of specific and non-invasive diagnostic tests for assessing cardiac involvement. While cardiac magnetic resonance (CMR) imaging is the standard imaging modality for diagnosing various etiologies of cardiomyopathy, its application in Lyme carditis remains understudied.

Background: Ticks are the primary vectors of numerous zoonotic pathogens, transmitting more pathogens than any other blood-feeding arthropod. In the northern hemisphere, tick-borne disease cases in humans, such as Lyme borreliosis and tick-borne encephalitis, have risen in recent years, and are a significant burden on public healthcare systems. The spread of these diseases is further reinforced by climate change, which leads to expanding tick habitats.
