Abstract:

   Coronavirus disease (COVID-19) is an infectious disease that is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It has affected the entire world. The clinical course of infection varies from asymptomatic to mild symptoms to life threatening conditions in affected individuals. An unbalanced immune response is responsible for many complications and even death in severe cases. Poor nutritional status is a major risk factor for infection as it makes the patient immunocompromised. A good dietary pattern boost immune system in combating infections. In thi

Abstract:

Currently, the infection caused by the new coronavirus COVID-19 is considered by the global community as an emergency of international concern. Rheumatologists are particularly concerned about this problem, since patients with immune-mediated inflammatory rheumatic diseases (IMIRDs) are at higher risk for infectious diseases and receive immunosuppressive treatment. The use of disease-modifying antirheumatic drugs and biological agents increases the incidence of serious infections, but insufficient/no monitoring of IMIRD activity is an even greater risk factor for infectious complications.

(1) Background: General infection control measures have been implemented at the societal level against COVID-19 since the middle of 2020, namely, hand hygiene, universal masking, and social distancing. The suppressive effect of the social implementation of general infection control measures on pediatric infections has not been systematically assessed.

Abstract:

The impact of the COVID-19 pandemic was very broad and substantial, affecting a variety of fields worldwide. In Japan, the infection began spreading in March 2020. At that time, the government alerted people to cancel overseas travel, and encouraged wearing of masks, handwashing, sanitizing and keeping social distance. We sought to determine how COVID-19 infections affected other infectious diseases by investigating the trends in seven gastrointestinal infections that are listed among the 77 important infectious diseases designated by the National Institute of Infectious Diseases.

Abstract:

COVID-19 has been associated with myriad manifestations as well as adverse outcomes. One of the less commonly reported consequences of COVID-19 is the occurrence of secondary infections in patients suffering acutely from COVID-19 or in those recuperating.

Severe lung damage and immunologic derangement resulting from SARS-CoV-2 infection predispose to superinfections. Risk factors for secondary IFI includes immunologi

Indeed, many pulmonary infections and non-infectious diseases can show similar CT findings and mimic COVID-19 pneumonia.

The optimal control strategy aims to minimize intervention costs and reduce infections by implementing five control measures, including prevention and vaccination of COVID-19, treatment of both symptomatic and asymptomatic COVID-19-infected individuals, treatment of COVID-19 and active TB co-infected individuals, and prevention of treatment failure in active TB cases.

One such opportunistic fungal infection is mucormycosis.

Abstract:

To effectively respond to an emerging infectious disease outbreak, policymakers need timely and accurate measures of disease prevalence in the general population. This paper presents a new methodology to estimate real-time population infection rates from non-random testing data. The approach compares how the observed positivity rate varies with the size of the tested population and applies this gradient to infer total population infections. Applying this methodology to daily testing data across U.S. states during the first wave of the COVID-19 pandemic, we estimated widespread undiagnosed COVI

Abstract:

Coronavirus disease 2019 (COVID-19) infection is currently a great cause of concern for the healthcare sector around the globe. SARS-CoV-2 is an RNA virus that causes a serious infection that is associated with numerous adverse effects and multiple complications associated with different organs and systems during its pathogenic cycle in humans. Individuals affected by COVID-19, especially elderly populations and immunocompromised people, are greatly vulnerable to opportunistic fungal pathogens. Aspergillosis, invasive candidiasis, and mucormycosis are widespread fungal coinfections in COVID-19

Abstract:

Concurrent infections are a common complication of viral respiratory infections. They pose diagnostic challenges due to an overlap of similar symptoms, resistance to treatment and extending length of hospital stay. In this review we will extensively discuss the most common concurrent infections in patients with coronavirus disease 2019 (COVID-19). A thorough literature search was conducted in online databases such as PubMed, Google Scholar and included systematic reviews, meta-analyses, prospective and retrospective cohort studies in this review. Bacterial co-infections are the most common con

We included all persons ≥18 years that had been fully vaccinated against COVID-19 for ≥14 days, between 1 February 2021 and 5 December 2021, in Belgium. The incidence of breakthrough infections (laboratory confirmed SARS-CoV-2-infections) was determined. Factors associated with breakthrough infections were analyzed using COX proportional hazard models. Among 8,062,600 fully vaccinated adults, we identified 373,070 breakthrough infections with an incidence of 1

Nearly 35 million cases and one million deaths over the nine months of the COVID-19 pandemic have been reported worldwide. Africa and some countries with endemic parasitic infections had a low incidence of COVID-19. By contrast, the United States and several European countries, having a non-endemicity of parasitic infections, recorded a high incidence of COVID-19. Some parasites have an immunomodulatory mechanism that can induce an immune tolerance state in the infected persons by balancing pro-inflammatory and anti-inflammatory responses.
