The pandemic of the new coronavirus COVID-19 has switched medicine around world on primary fight against this infection. Patients with chronic liver diseases require increased attention doctors during an epidemic, since background exacerbation their disease, not only risk contracting COVID 19 viral infection increases, but also its more severe course. confirmed damage - high biochemical activit...
Avian influenza viruses sporadically cross the species barrier to mammals, including humans, in which they may cause epidemic disease. Recently such an epidemic occurred due to the emergence of avian influenza virus of the subtype H10N7 (Seal/H10N7) in harbor seals (Phoca vitulina). This epidemic caused high mortality in seals along the north-west coast of Europe and represented a potential ris...
Besides the epidemic threshold, the recently proposed viral conductance w by Kooij et al. [11] may be regarded as an additional characterizer of the viral robustness of a network, that measures the overall ease in which viruses can spread in a particular network. Motivated to explain observed features of the viral conductance w in simulations [29], we have analysed this metric in depth using th...
Clinical disease associated with porcine epidemic diarrhea virus (PEDV) infection in naïve pigs is well chronicled; however, information on endemic PEDV infection is limited. To characterize chronic PEDV infection, the duration of infectious virus shedding and development of protective immunity was determined. On Day 0 (D0), a growing pig was challenged with PEDV and 13 contacts were commingled...
As the COVID-19 epidemic is still ongoing, a more rapid detection of SARS-CoV-2 infection such as viral antigen-detection needs to be evaluated for early diagnosis disease. Here, we report dynamic changes antigens in nasopharyngeal swabs patients and its association with nucleic acid clearance clinical outcomes. Eighty-five were enrolled antigens, including 57 anti-SARS-CoV-2 antibody negative ...
Hepatitis C virus (HCV) has emerged as the cause of the second major epidemic of viral infection after human immunodeficiency virus (HIV) within the past two decades, and coinfection of HIV and HCV represents a growing problem for the future. This article reviews the current evidence on the epidemiology and clinical implications of an interaction between HIV-1 and HCV infection, and the current...
Herpes Simplex Virus (HSV) is the most common cause of non-epidemic, acute focal central nervous system infection. HSV type 1 (HSV-1 or Human Herpes Virus-1 [HHV-1]) is commonly associated with oropharyngeal infections, keratoconjunctivitis, and infections of the central nervous system, whereas HSV type 2 (HSV-2 or HHV-2) commonly produces genital infections. Severe disseminated HSV infection m...
Epidemic viral conjunctivitis is a highly contagious disease that is encountered year-round. The causative agents are mainly adenoviruses and enteroviruses. It occurs most commonly upon infection with subgroup D adenoviruses of types 8, 19, or 37. For common corneal involvement of human adenovirus type 8 epidemic keratoconjunctivitis, full-layer epithelial detachment is rarely seen. Herein, we ...
In this paper, we present a fuzzy approach to the Reed-Frost model for epidemic spreading taking into account uncertainties in the diagnostic of the infection. The heterogeneities in the infected group is based on the clinical signals of the individuals (symptoms, laboratorial exams, medical findings, etc.), which are incorporated into the dynamic of the epidemic. The infectivity level is time-...
The HIV-1 epidemic among men who have sex with men (MSM) has been spreading throughout China. Shanghai, a central gathering place for MSM, is facing a continuously increasing incidence of HIV-1 infection. In order to better understand the dynamics of HIV-1 diversity and its influence on patient's immune status at baseline on diagnosis, 1265 newly HIV-1-infected MSM collected from January 2009 t...
