Tick-borne encephalitis epidemic in Hungary 1951-2021: The story and lessons learned.

The authors analysed epidemiological data of the Hungarian tick-borne encephalitis epidemic from the past seven decades. A total of 911 meningitis serosa cases were described from 1930-1950 s by local hospital physicians, indicating that the virus had been present in the country decades before its official identification in 1952. The virus spread freely in the 1950s-1960s, occupying almost all habitats where ticks occurred in large numbers.

Oculoglandular Tularemia From Crushing an Engorged Tick.

We report on an unusual case of oculoglandular tularemia acquired after crushing a tick removed from a dog. As a droplet sprayed into the patient's eye the eyelids became inflamed, and on the fourth day, a high fever started. Prompt antibiotic treatment prevented serious complication.

[Borrelia miyamotoi: a recently identified human pathogenic tick-borne relapsing fever spirochete].

Borrelia miyamotoi is a recently described relapsing fever spirochete transmitted by ticks of the Ixodes ricinus complex. This pathogen is different from Borrelia burgdorferi sensu lato (the Lyme borreliosis spirochetes) in its epidemiology, ecology and also genetics. Over 50 patients have been described worldwide with Borrelia miyamotoi disease, and three immunocompromised patients were reported with neurological symptoms.

[Bexsero, a novel vaccine against meningococcus].

Meningococcus B is the most prevalent Neisseria meningitidis serogroup isolated in Hungary. Bexsero is one of the vaccines developed against it, which has been available in Hungary since the summer of 2014. The authors summarize the most important issues and open questions concerning the disease and the vaccine based on literature review.

Transmission of Rickettsia slovaca and Rickettsia raoultii by male Dermacentor marginatus and Dermacentor reticulatus ticks to humans.

We analyzed rickettsial DNA of ticks from tick-borne lymphadenopathy (TIBOLA) patients. Dermacentor marginatus (9/17) and Dermacentor reticulatus (8/17) transmitted rickettsiae to a similar extent. Rickettsia raoultii was detected in more ticks than Rickettsia slovaca.
