The objective: to analyze the course of the new coronavirus infection (COVID-19) in children with active respiratory tuberculosis. Subjects and methods. The article describes results of retrospective analysis of the course of the new coronavirus infection in 25 children (3-12 years old) with active respiratory tuberculosis during the outbreak of COVID-19 in an in-patient TB unit.Results. 24 (96%) persons got infected after the close exposure to the coronavirus infection, and 1 (4%) child didn't get infected. The diagnosis was verified by polymerase chain reaction (detection of RNK of SARS-CoV-2) in 33.3%, by enzyme immunoassay (detection of IgG antibodies to SARS-CoV-2 in 1 month after quarantine removal) in 100%. 58.3% of children with respiratory tuberculosis (14 people) infected with coronavirus infection had minimal respiratory symptoms, that did not differ from signs of other respiratory viral infections; clinical manifestations of the disease were completely absent in 41.7% (10) patients. Coronavirus pneumonia was diagnosed in 4 (16.7%) children who suffered from COVID-19, they had no clinical signs of lower respiratory tract disorders and no body temperature increase; 3 patients had no signs of respiratory viral infection; in all cases, the lung damage detected by computed tomography didn't exceed 10%. In 2 months after the removal of quarantine, no IgG antibodies to SARS-CoV-2 were detected in 2 out of 10 examined children (20.0%), thus there was a chance for re-infection. No mutual aggravating effect of coronavirus infection and tuberculosis was revealed in their combination over the entire observation period (4 months).

The article is devoted to the peculiarities of clinical manifestations and the severity of a new coronary virus infection in a university student transferred to an observatory organized in a hotel-type hostel to prevent the spread of COVID-19 among students living in hostels. The data on the epidemiological history of the patient, the results of clinical observation and examination are provided. The tactics of managing a patient with a suspected of COVID-19 on an outpatient basis, symptoms that determine the indications for hospitalization, the results of examination and treatment in a hospital, and further observation at the observatory are considered. A new coronavirus infection can lead to a rapid deterioration in the condition of young patients, which does not correlate with indicators indicating lung damage on the 5th day of the disease. Persistent hyperthermia and severe weakness with anorexia can be indicators of the complicated course of the disease, including the development of hyperactive inflammatory syndrome. Hypochromic anemia can be another disease, which is an unfavorable background for the development of COVID-19. The course of the new coronavirus infection in young patients requires careful attention and further study.

Abstract Background: Apart from the huge worldwide economic losses often occasioned by bovine coronavirus (BCoV) to the livestock industry particularly cattle, continuous surveillance of the virus in cattle and small ruminants is essential in monitoring variations in the virus that could enhance host switching. In this study, we collected rectal swabs from a total of 1,498 cattle, sheep and goats. BCoV detection was based on reverse transcriptase polymerase chain reaction. Sanger sequencing of the partial RNA-dependent RNA polymerase (RdRp) region for postive samples were done and nucleotide sequences were compared with homologous sequences from the GenBank.Results: The study reports a BCoV prevalence of 0.3% consisting of 4 positive cases; 3 goats and 1 cattle. Less than 10% of all the animals sampled showed clinical signs such as diarrhea and respiratory distress except for high temperature which occurred in > 1000 of the animals. However, none of the 4 BCoV positive animals manifested any clinical signs of the infection at the time of sample collection. Bayesian majority-rule cladogram comparing partial and full length BCoV RdRp genes obtained in the study to data from the GenBank revealed that the sequences obtained from this study formed one large monophyletic group with those from different species and countries. The goat sequences were similar to each other and clustered within the same clade. No major variations were thus observed with our isolates and those from elsewhere.Conclusion: Given that Ghana predominantly practice the extensive and semi-intensive systems of animal rearing, our study highlights the potential for spillover of BCoV to small ruminants in settings with mixed husbandry and limited separation between species.

AbstractLeishmaniasis is a widespread, vector-borne parasitosis causing clinical manifestations in animals and in humans. In dogs, Canine Leishmaniasis has been reported in as much as 50 countries and the Mediterranean basin is known to be one of the most affected zones. Within these areas, the Island of Sardinia (Italy) has long been considered endemic for leishmaniasis and the presence of two arthropod vectors has recently been reported there. Nevertheless, to date, no epidemiological surveys regarding CanL have been carried out on the island. Hence, for the first time, the seroprevalence and the risk factors were investigated. Blood samples, as well as clinical and general information from 1.147 dogs, were collected and analyzed. Dogs consisted of two distinct populations, namely “owned dogs” and “kennel dogs.” Anti-Leishmania IgG antibodies were detected using IFAT and samples were scored as positive at a cut-off dilution of 1:80. Data was analyzed using a Chi-squared test and bivariate and multivariate analyses were performed. Overall, 15.4% of dogs were found to be infected with CanL while only 44.1% of these animals exhibited clinical signs. Owned dogs (27.2%) were found to be infected more often than kennel dogs (10.6%); male dogs were found to be more frequently infected than female dogs and the number of infected animals increases with age. The present survey confirmed the endemic nature of leishmaniasis in Sardinia with a similar seroprevalence as mainland Italy. The results obtained serve as validation for the hypothesis that, in endemic areas, clinical CanL representations constitute only a fraction of the leishmaniasis cases.

Human metapneumovirus (HMPV) is a leading cause of acute respiratory infection, particularly in children, immunocompromised patients, and the elderly. HMPV, which is closely related to avian metapneumovirus subtype C, has circulated for at least 65 years, and nearly every child will be infected with HMPV by the age of 5. However, immunity is incomplete, and re-infections occur throughout adult life. Symptoms are similar to those of other respiratory viral infections, ranging from mild (cough, rhinorrhea, and fever) to more severe (bronchiolitis and pneumonia). The preferred method for diagnosis is reverse transcription-polymerase chain reaction as HMPV is difficult to culture. Although there have been many advances made in the past 16 years since its discovery, there are still no US Food and Drug Administration-approved antivirals or vaccines available to treat HMPV. Both small animal and non-human primate models have been established for the study of HMPV. This review will focus on the epidemiology, transmission, and clinical manifestations in humans as well as the animal models of HMPV pathogenesis and host immune response.

Background: Spain has been severely affected by the COVID-19 epidemic, with 195,944 persons infected and 20,453 deaths at the time of writing. Older people with respiratory or cardiac conditions are most at risk. Objective: The aim was to compare respiratory symptoms in nursing home residents and patients with uncontrolled asthma, who are considered vulnerable to COVID-19. Methods: We studied 134 nursing home residents and 139 patients with uncontrolled asthma, groups vulnerable to COVID-19. Demographic characteristics, clinical manifestations, outcomes, key laboratory results, and radiological images were collected from medical records. COVID-19 infection was detected by polymerase chain reaction (PCR). Results: Thirteen (9.3%) patients with uncontrolled asthma, all receiving inhaled corticosteroids were infected by COVID-19. Eighty (60%) nursing home residents were infected; only 28, all of whom had received inhaled corticosteroids, had a good prognosis. Conclusions: Early treatment with inhaled corticosteroids may be helpful in COVID-19 infection. Persons with an allergy might have some protective mechanisms against coronavirus.

In the early stages of the COVID-19 pandemic, many guidelines for the management of patients with new coronavirus infection did not include recommendations for the use of non-invasive ventilation (NIV) due to the concerns that NIV could be accompanied by high tidal volumes that could cause lung damage. In addition, there was an opinion that NIV increases the risk of spreading bioaerosol containing the SARS-CoV-2 virus. At the same time, NIV was widely used in real clinical practice in the management of severe patients with COVID-19 (in some countries, up to 60% of all respiratory support methods). The accumulated experience demonstrates that when applying NIV, the risk of contamination with viral infections is minimized with adequate use of personal protective equipment. To date, the results of a limited number of studies about effectiveness of NIV in hypoxemic acute respiratory failure (ARF) in patients with COVID-19 are available. In most studies, the need for tracheal intubation and hospital mortality, were on average, 20 – 30%, that suggests a fairly high effectiveness of NIV in ARF in patients with COVID-19.

Coronavirus infection (CVI) is a group of acute ubiquitous infectious diseases known since the 60s 19 century. The clinical picture of CVI is characterized by damage to the respiratory system from mild forms of acute respiratory viral infection to the development of a severe acute respiratory syndrome, as well as involvement of other organs in the pathological process of the gastrointestinal tract. For a long time, coronaviruses were not given attention, since it was believed that they were able to cause only mild respiratory diseases. It is known that children and adolescents are less susceptible to infection than adults. In the etiological structure of acute respiratory viral infections among hospitalized children, coronaviruses account for 69%. The introduction of multiplex polymerase chain reaction (PCR) with the inclusion of coronaviruses in practice has shown their role in the occurrence of severe diseases of the lower respiratory tract. Since 2002, outbreaks of coronavirus infection caused by previously unknown pathogens (SARS-CoV, MERS-CoV, SARS-CoV-2) have been observed in the world. New coronaviruses have genetic features and are relatively highly resistant in the environment. The diseases they cause are distinguished by the predominance of severe forms with high mortality due to the development of acute respiratory distress syndrome and sepsis. In December 2019, an outbreak of pneumonia caused by the SARS-CoV-2 virus began in China; in February 2020, the disease was called COVID-2019. In connection with the trend towards the global spread of new infections March 11, 2020, the World Health Organization announced a pandemic. The lecture covers the issues of epidemiology, pathogenesis, clinic, diagnosis and treatment of coronavirus infection, taking into account the emergence of new pathogens.

During the pandemic of a new coronavirus infection one of the most serious complications is pneumonia. When entering a specialized pulmonology Department, the presence of pneumonia is confirmed by computed tomography (CT), the etiology is confirmed by the detection of SARS-CoV-2 RNA by PCR, the article analyzes the indicators of blood analysis when patients are admitted to the hospital. All admitted patients were divided into 2 groups. Group 1 of the study - with a new coronavirus infection Covid-19, confirmed by the detection of PCR-RNA SARS-CoV-2 (n=27). Group 2 consisted of 65 patients (70.7%) with lung tissue damage characteristic of Covid-19 according to CT, who had a negative analysis of PCR-RNA SARS-CoV-2. Statistically significant deviations were shown in a decrease in the percentage and absolute content of lymphocytes, monocytes and platelets, and an increase in neutrophils. The comparative analysis in the groups with positive and negative PCR analysis for the detection of SARS-CoV-2 RNA showed no statistically significant differences. It can be assumed that with the similarity of clinical manifestations and CT-data, a negative result of PCR-RNA SARS-CoV-2 can be diagnosed as «lung damage caused by COVID-19 infection».

Abstract Aim Reports describing coronavirus disease 2019 (Covid-19) in children are fewer than adult studies due to milder clinical picture. We aimed to share our experience at a single center with an emphasis on collective decision making. Materials and Methods A suspected case was defined as the presence of symptoms suggestive of COVID-19 and/or positive contact history. SARS-CoV-2 PCR positive patients were defined as confirmed COVID-19. Between March 12, 2020, and May 15, 2020, all children presenting with fever, cough, or respiratory difficulty were investigated for COVID-19. A total of 719 children were examined at outpatient clinics, and 495 were tested with polymerase chain reaction (PCR) for suspicion of COVID-19. A team was organized for monitoring and treating patients either as outpatients or hospitalization. Patients were evaluated in terms of age, gender, travel history, epidemiological history, clinical symptoms and signs, laboratory and radiological findings, treatment, and outcome. Results Sixty patients were hospitalized for suspicion of COVID-19. Forty-three patients were diagnosed as probable or confirmed COVID-19. 21 of 43 patients (48.8%) were PCR confirmed. The remaining 22 were diagnosed by epidemiologic history, clinical assessment, and computerized thorax tomography (CT) findings. The median age was 126 and 78.5 months in PCR positives and PCR negatives, respectively and the youngest patient was a 28 days old baby. Nineteen of the patients had an upper respiratory infection (44.1%). Although five patients had no clinical signs, chest X-ray, or CT revealed pneumonia. Conclusions As previously reported, the clinical manifestations of COVID-19 in children are mostly mild. Even very young kids can become infected following exposure to sick family members. International and local guidelines are valuable for decision making since it is a new disease. A combination of chest disease, infectious diseases, and emergency care physicians approach will aid the appropriate management of cases.

AbstractToxocariasis is a common human zoonosis, which induces a clinically unapparent course of infection. Diagnosis is difficult and relies upon serological testing (searching of specific IgG antibodies by ELISA), laboratory abnormalities and clinical manifestations. The polymerase chain reaction (PCR) technique was adapted for the detection of Toxocara canis larvae in a host tissue. Mongolian gerbils (Meriones unguiculatus) were used as an animal model for human toxocariasis. 8 animals were inoculated with 1000 T. canis eggs, four uninfected were used as control. At 3, 5, 7, and 14 days post-infection, 2 infected and 1 control gerbil were killed and their livers were used for molecular analysis. Specific primer in the PCR reaction allowed identification of T. canis larvae, with the parasite gDNA found in the liver of all infected gerbils. The results indicate that the PCR method has a potential as a supporting technique for the diagnosis of human toxocariasis.
