An 85-year-old man presented to his family physician with complaints of generalized weakness, fatigue, loss of appetite, excessive sleeping, and mild laryngitis. He reported that his temperature taken orally at home that morning was 102.6 °F. These symptoms arose during the previous week, before which he had been healthy, exercising vigorously every day. His past medical history included type 2...

Objective: To identify common and distinctive characteristics of the epidemical process tick-borne encephalitis Lyme borreliosis on example Republic Karelia. Materials methods. The frequency infected tick bites, dynamics, intensity, territorial, gender, age social features incidence in 2000–2021 were analyzed according to official statistics, epidemiological examination foci laboratory studies....

Ethiopia has the largest livestock population in Africa, but the contribution for the economic aspect of the country is still lowest and disease can be considered as major constrain. Ticks are the most important ectoparasites of livestock in tropical and sub-tropical areas. Ethiopia is not exceptional and ticks are responsible for severe economic losses both through the direct effects of blood ...

We present a simple model of the dynamics of heartwater that we use to explore and better understand various aspects of this disease. We adapted the Ross-Macdonald model for malaria epidemiology so that we could consider both host and vector populations, and evaluate the interactions between the two. We then use two more biologically detailed models to examine heartwater epidemiology. The first...

Chronic Lyme borreliosis is often considered as a diagnosis option in patients with long lasting miscellaneous symptoms after tick bites. Despite new codified diagnosis algorithm and treatment, persistent signs and symptoms frequently occur. The aim of the study was to assess the diagnosis of Tick Associated PolyOrganic Syndrome (TAPOS) and to evaluate the treatment’s efficacy. A consecutive ca...

Two forms of tick-borne leukocytotropic rickettsioses have been recognized in California since the mid-1990s: human monocytic ehrlichiosis (HME) caused by Ehrlichia chaffeensis and human granulocytic anaplasmosis (HGA) caused by Anaplasma phagocytophilum. Between 1997 and 1999, two cases of HME and four cases of HGA were diagnosed in residents of southern Humboldt County, California. Environmen...

Relevance. According to official data, in 2020 Russia, Ixodic tick-borne borreliosis took the leading position prevalence and registration frequency among infections, which amounted 38.5% of all cases natural focal transmissible infections. In Tomsk region for many years, average long-term incidence exceeds Russian one by more than 3 times. Aim. Identify features clinical epidemiological manife...

We review the epidemiological and clinical characteristics of tick-borne encephalitis, and summarise biological and virological aspects that are important for understanding the life-cycle and transmission of the virus. Tick-borne encephalitis virus is a flavivirus that is transmitted by Ixodes spp ticks in a vast area from western Europe to the eastern coast of Japan. Tick-borne encephalitis ca...

The tick-borne encephalitis virus (TBEV) is a flavivirus transmitted to humans, usually via tick bites. The virus causes tick-borne encephalitis (TBE) in humans, and symptoms range from mild flu-like symptoms to severe and long-lasting sequelae, including permanent brain damage. It has been suggested that within the population of viruses transmitted to the mammalian host, quasispecies with neur...

Previously reported babesiosis cases in children have been mostly acquired by blood transfusion (10). The patient had no history of transfusions with blood products and had never traveled outside his home town before disease onset. Although he and his parents did not recall any tick bites, he was at high risk for exposure to ticks because he often played with his dog, which frequently went outd...
