Acute eosinophilic pneumonia (AEP) is a cause of acute respiratory failure, and differs from other eosinophilic pneumonias by its acute onset, presence of fever and acute hypoxaemia. Cases of 2009 influenza A (H1N1) virus infection have included rapidly progressive lower respiratory tract disease resulting in respiratory failure. We describe the case of a young patient who showed dyspnoea, feve...

Respiratory viruses can cause a wide spectrum of pulmonary diseases, ranging from mild, upper respiratory tract infections to severe and life-threatening lower respiratory tract infections, including the development of acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). Viral clearance and subsequent recovery from infection require activation of an effective host immune resp...

Background: The main viral causes of acute respiratory diseases (ARDs) include influenza viruses A and B, respiratory syncytial virus (RSV), adenovirus (ADV), rhinovirus, and parainfluenza viruses (PIV). This study aimed to investigate the prevalence of respiratory RSV, ADV and rhinovirus in patients with flu-like symptoms admitted to Mazandaran province health centers in north of Iran. Metho...

Introduction Chlamydia pneumoniae was initially recognized as a cause of acute lower respiratory tract infections such as pneumonia and bronchitis in both adults and children (1-7), hence the species name “pneumoniae.” Moreover, C. pneumoniae was noted in some individuals to cause a persistent respiratory tract infection following an acute infection (8), which is entirely consistent with the kn...

The following principles of appropriate antibiotic use for adults with nonspecific upper respiratory tract infections apply to immunocompetent adults without complicating comorbid conditions, such as chronic lung or heart disease. 1. The diagnosis of nonspecific upper respiratory tract infection or acute rhinopharyngitis should be used to denote an acute infection that is typically viral in ori...

The COVID-19 pandemic, caused by the Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) infection poses a serious threat for heart [1,2]. Myocardial damage has been observed in larg...

Long COVID-19 is a constellation of symptoms following confirmed acute infection. SARS-CoV-2 infection does not only give rise to respiratory problems but also other non-respiratory conditions. The and duration may vary among the patients its treatment based on clinical presentation. mildly infected was scarcely studied reported, therefore we present previously healthy, stage 2 patient who expe...

Abstract We conducted 3 population-based cross-sectional surveys, at 1-month intervals, to estimate the prevalence and time-trend of severe acute respiratory syndrome coronavirus 2 infection in Puducherry, India. Seropositivity rate increased from 4.9% 34.5% over months was 20-fold higher than number diagnosed cases infection.
