ABSTRACT
Relevance. The rapid spread of new pathogens inevitably leads to the occurrence of joint circulation with already known infectious agents, leading to the development of mixed infections. The simultaneous circulation of the pandemic coronavirus SARS-CoV-2 with a highly contagious measles virus leads to the development of mixed infections in people who have not been sick or vaccinated against measles. Aims. Review cases of co-infection with measles and COVID-19 in Moscow. Material and methods. A retrospective study of cases of measles and COVID-19 co-infection in three children with a description of the epidemiological and clinical picture of the disease. Results. In all observed children, the manifestation of the disease was typical for measles, the diagnosis of COVID-19 was established based on a laboratory study carried out in a hospital, which gave reason to count. That the infection with SARS-CoV-2 occurred after the infection of children with measles. Conclusions. Different incubation periods can lead to several options for the development of co-infection. The similarity of clinical symptoms at the onset of the disease does not allow excluding a certain infection clinically, without laboratory verification. © Zvereva NN et al.
ABSTRACT
Objective: Determine the role of infectious diseases in the development of strokes in children and to identify risk groups for its progression. Materials and Methods: A retrospective analysis of 660 case histories of children aged 1 months to 18 years old, hospitalized in Morozov Children's City Clinical Hospital with stroke in the period from 2016 to July 2020 was carried out. Results. An infectious disease or fever 4 weeks before stroke is diagnosed in 78 (12%) cases. Infections more often act as a stroke trigger in children under 7 years old (28% in children under one year old). The incidence of strokes against a background of a bacterial infection is higher than against a background of a viral infection (47% versus 35%). Among bacterial infections, meningitis (35%), otitis media (24%), pneumonia (18%) prevailed. With a viral infection, viruses of Herpes are more common (44%), as well as respiratory viruses (37%). Two cases of cerebrovascular accident were revealed in children who have undergone a new coronavirus infection SARS-CoV-2 (7%). Among the types of stroke, with bacterial infection, sinus thrombosis was more common (50%), among viral infection, the most common was ischemic stroke (60%). The presence of an additional risk factor was revealed in 72%, most often these were prothrombotic conditions (35%).
