Respiratory virus co-infections have been suggested to happen frequently and exacerbate patients’ conditions, but little is known about the detailed rates and the combinations of viruses during the COVID-19 pandemic period. A total of 255 symptomatic patients who underwent multiplex PCR tests were analyzed, and it was found that 6 (6/255=2.4%) patients were infected with multiple viruses. The patients ranged in age from 1 to 38 years, and one female patient was pregnant. Of the 6 patients, 4 had fever, and 5 had human rhinovirus/enterovirus and another virus. These data suggested that the rate of respiratory virus co-infection was low, and the combination of SAS-CoV-2 and other viruses was rare even during the COVID-19 pandemic.Full article

Background: The World Health Organization (WHO) has declared COVID-19 a public health emergency of international concern. In this context, effective and affordable diagnostic procedures are essential for identifying and managing cases. Complete blood counts (CBC) are among the most common and readily available diagnostic tests. The current study aimed to evaluate the efficacy of CBC in diagnosing COVID-19 and identifying cases. Patients and Methods: A case-control study was conducted on 173 patients at Ain Shams University Hospitals over a period of three months. Patients were allocated into two groups according to COVID-19 PCR results: Group 1 included patients with COVID-19 positive PCR, and Group 2 included patients with COVID-19 negative PCR. Results: The study found that differential CBC had significant value in diagnosing COVID-19 disease. Many COVID-19 patients had lymphopenia and leucopenia compared to non-COVID-19 suspected patients. The low values of leukocytes, neutrophils, lymphocytes, and eosinophils with a CBC test were found to be valuable in the initial diagnosis of COVID-19. Conclusion: The definitive diagnosis of COVID-19 requires RT-PCR analysis, which is time-consuming and less accessible. Thus, the initial diagnosis and treatment of patients may be delayed. This study suggests that CBC, which is easily available and affordable, can be valuable in the early identification of COVID-19 cases, allowing for prompt treatment and management.Full article

As a result of the virus's global dissemination, novel COVID-19 infections have emerged as a significant obstacle for all healthcare professionals to overcome. Dental specialist plays an effective role in the prevention of coronavirus. Dental care units and settings face various problems relating to the transmission of disease during treatment and dental operations. Blood, saliva, and mixed water droplets possessing the virus cause contamination of equipment used for dental treatment. Both patients and workers may become transmitters and infectors of COVID-19 through direct contact during dental operations. Both dental workers and patients are likely to become infectors and transmitters of COVID-19. The dental care routine is very effective as we discussed below the prevention steps are very effective. All healthcare workers at the dentistry clinics, including nurses, should collaborate to prevent the spread of the COVID-19 virus among patients.Full article

Background: On the first of October 2018, the Egyptian Ministry of Health and Population (MOHP) launched an initiative; named “100 Million Healthy Lives”, for nationwide screening of hepatitis c virus (HCV) and non-communicable diseases (NCDs). Egypt has the highest prevalence of HCV infection in the world where about 10% of the Egyptian population is affected by the disease. NCDs are the leading cause of mortality in Egypt and account for about 84% of all deaths. This study was conducted to a) Estimate the prevalence of participation in the national campaign on viral hepatitis C and non-communicable diseases among administrative workers in Ain shams University (ASU), b) Estimate the self-reported satisfaction of these participants with the campaign. Subjects and Methods: A cross-sectional study was conducted on 400 administrative workers of ASU faculties between March and August 2019 in Cairo, Egypt. A multistage random sample was done. Results: The study showed that 96% of the study group participated in the campaign. “Evaluating health status” was considered the main reason for participation at 92%, followed by "desire to obtain follow-up card", at 36%. Non-participation rate was about 4% and the main cause of non-participation was “fear of needle prick". About 91% of the participants were satisfied with the provided services. Mass media played a major role in awareness about the campaign for 91% of participants. Conclusions: The majority of the study group participated and was satisfied with the campaign. Mass media played a major role in participant awareness of the campaign.Full article

The initial omicron (B.1.1.529) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) subvariants, BA.1 and BA.2 (BA.1/2), were progressively displaced by BA.5 in Japan, which showed not only higher transmittivity and less pathogenicity, but also differences in antibiotic use according to the difference in the clinical course of BA.5 compared with BA.1/2 infections. BA.5 patients received more antibiotics, especially ampicillin/sulbactam, although ceftriaxone and meropenem were used significantly in the BA.1/2 period. These data suggest an increased incidence of aspiration pneumonia in elderly patients in the BA.5 period, and we should consider changing the management tactics for COVID-19.Full article

Background: In December 2019, a cluster of patients with unexplained viral pneumonia was identified in Wuhan, China. Since March 11th 2020 the WHO declared COVID 19 as a pandemic with rising number of cases all over the world. Aim of the work: The aim of the study was to measure the percentages of possible, probable and provisionally excluded cases among the first 500 attendants of the triage of Ain Shams University Hospital and describe their epidemiological and clinical characteristics. Patients and Methods: This was a retrospective descriptive case series study including the first 500 patients attending the triage of Ain Shams University Hospitals from March 29th to May 31st. A constructed questionnaire in the form of a scoring system was used and data was collected through interviewing the patients after appropriate consent. Results: As regard the scoring system, 72.2% of patients had new onset of cough or old worsened cough in the previous 3 days, 59.2% had sore throat and 59% had dyspnea. Out of the 500 cases 33.2% were probable, 38.2% were possible and 28.2% were provisionally excluded. Conclusion: COVID-19 pneumonia usually occurred at an age younger than 47 years and it was more predominant in the male gender. The most common initial clinical presentations were new dry cough or chronic cough with worsening over the last 3 days, sore throat and/or runny nose and fever. Thirty-eight percent were classified as possible COVID-19 cases, and 33% were classified as probable.Full article

The SARS-COV-2 rapid spread caused an international public health emergency with unprecedented rates of morbidity and mortality. Post COVID-19 condition occurs as a spectrum of symptoms that present four or more weeks after acute infection with SARS-CoV-2. Most published data to date state 50-70% of hospitalized patients experienced at least one post-acute COVID-19 symptom up to 3 months after discharge. Commonly reported symptoms include; neurocognitive post COVID-19 (fatigue, dizziness, inattention, and brain fog), respiratory post-COVID (dyspnea, chest pain, and cough), and mental health related symptoms (insomnia, depression, and post-traumatic stress disorder). Additionally, gastro-intestinal post COVID-19 (diarrhea, vomiting, and abdominal pain) along with decline in quality of life and decreased ability to perform activities of daily living were reported. The response to post COVID-19 symptoms is still in its infancy despite being an emerging crisis as scientific evidence and robust data are nonetheless required for clear definition, identification of time frame, classification and management of the condition. New studies are needed to identify total and individual incidence/prevalence rates of different clinical presentations of post COVID-19 symptoms. These future studies will help us to o improve early recognition of long term symptoms after acute infection of COVID-19.Full article

Many attempts have been made to repurpose existing and approved drugs for the treatment of COVID-19 infection. This involves anti-malarial drugs such as hydroxychloroquine and chloroquine, which have been shown to be less successful than initially believed, with a substantial risk of often fatal complications and interactions. This also involves Remdesivir, which has been shown to decrease recovery time significantly in hospitalized patients. However, for patients who are not yet hospitalized, there is no currently accepted treatment. Treating patients before they need to be admitted or even prophylactically could greatly decrease the load on hospitals, protect healthcare workers and reduce the spread of COVID-19. An in-vitro study indicated that Ivermectin was dynamic against COVID-19-infected cell. Ivermectin has antimicrobial, antiviral, and anticancer, immunomodulatory properties. This drug could reduce the viral load in COVID-9 infected patients, with potential effect on disease progression and spread. Therefore, Ivermectin may be a therapeutic choice for treatment of COVID-19, however, there is still a lack of evidence-based studies to support ivermectin treatment of patients with COVID-19.Full article

Probiotics, prebiotics, and synbiotics modify various aspects of local and systemic immune function in multiple experimental models. However, their impact and mechanisms of action are not known across all products or noticed in every population studied, and impacts on in vitro, ex vivo, or other measures of immune function do not necessarily result in an impact on infection and illness in vivo. Studies have discussed that intestinal microbiota has an essential role in enhancing the immune system against viruses. The regulatory impact of the intestinal microbiota on viral infection is connected with local and systemic immune responses and plays a part in congenital and adaptive immune responses. The microbiota composition critically modulates the production of virus-specific CD4 and CD8 T cells and antibody responses following influenza virus infection. The intestinal microbiota has an important role in the stabilizing of immune homeostasis by augmenting the integrity of the barrier functions of the gut mucosa, which is a crucial aspect of systemic immunity. In conclusion, the intestinal microbiota can influence organismal immunity locally and systemically, proximally, and distally. Studying the possible mechanism by which the intestinal microbiota maintains host immunity can provide a clearer understanding of the occurrence and development of diseases.Full article
