Abstract Background Although acute respiratory tract infections (RTI) have been recognized as a significant cause of illness in returning travelers, few studies have specifically evaluated the etiologies of RTI in this population. Methods This prospective investigation evaluated travelers returning from countries with endemic influenza A(H1N1) 2009, and who were seen in our department at the onset of the outbreak (April–July 2009). Patients were included if they presented with signs of RTI that occurred during travel or less than 7 days after return from overseas travel. Patients were evaluated for microbial agents with RespiFinder plus assay, and throat culture according to clinical presentation. Results A total of 113 travelers (M/F ratio 1.2:1; mean age 39 y) were included. They were mainly tourists (n = 50; 44.2%) mostly returning from North America (n = 65; 58%) and Mexico (n = 21; 18.5%). The median duration of travel was 23 days (range 2–540 d). The median lag time between return and onset of illness was 0.2 days (range 10 d prior to 7 d after). The main clinical presentation of RTI was influenza-like illness (n = 76; 67.3%). Among the 99 microbiologically evaluated patients, a pathogen was found by polymerase chain reaction (PCR) or throat culture in 65 patients (65.6%). The main etiological agents were influenza A(H1N1) 2009 (18%), influenza viruses (14%), and rhinovirus (20%). A univariate analysis was unable to show variables associated with influenza A(H1N1) 2009, whereas rhinorrhea was associated with viruses other than influenza (p = 0.04). Conclusion Despite the A(H1N1) 2009 influenza pandemic, rhinovirus and other influenza viruses were also frequent causes of RTI in overseas travelers. Real-time reverse transcription-PCR and nasopharyngeal swab cultures are useful diagnostic tools for evaluating travelers with RTI.

ABSTRACT Viruses that cause respiratory tract infections are the most common agents of infectious diseases in humans throughout the world. A virus that infects the respiratory system, may induce various clinical symptoms. What is more, the same symptoms may be caused by different viruses. The aim of the study was to analyze the prevalence of enteroviruses that cause respiratory infections in patients with influenzavirus A/H1N1 hospitalized in the Lublin province. The experimental material was throat and nose swabs taken from patients hospitalized in Lublin and Tomaszow Lubelski. In the group of 44 patients (20 women and 24 men) infected with influenza A/H1N1, the genetic material of enteroviruses was detected in 13 patients (29.5%). Respiratory viruses co-infections are very common in hospitalized patients. Studies show that co-infection with influenza virus and enterovirus are more common in children than in adults. Moreover, viral respiratory tract infections are independent from the patients’ gender.

Introduction: In India and worldwide, there are millions of cases of acute respiratory infections annually killing hundreds of thousand people. It also has billions of dollars of losses worldwide. There are frequent outbreaks of deadly infections such as severe acute respiratory syndrome (SARS) in 2003, caused by a novel coronavirus (SARS-CoV), the novel swine-origin influenza A (H1N1) virus in Mexico in March 2009, Middle East respiratory syndrome coronavirus (MERS-CoV) in 2012 and the current pandemic with Novel CoronaVirus -Covid19. I did my research to find a common effective, safe, and cheap therapynamed as Ozonated air inhalation therapy (OAIT) for respiratory infections. Materials and methods: In the last one year, I treated 21 patients (group A) with upper and lower respiratory tract infections (URTI and LRTI) with 0.1 ppm Ozonated air inhalation therapy (OAIT). OAIT was given as a monotherapy. In the same time period, 36 patients (group B) were given conventional treatment in the form of antibiotics, anti-histaminic and analgesics kept as control.

Dilutional Hyponatraemia

The syndrome of inappropriate antidiuretic hormone (SIADH) secretion is a frequent cause of hyponatraemia. It is a dilutional hyponatraemia secondary to impaired urinary dilution in the absence of renal disease or any identifiable non-osmotic stimulus known to induce antidiuretic hormone secretion. SIADH can arise secondary to various respiratory tract infections; however, the association between SIADH and influenza A infection is described in only a few cases in the literature. The authors present a case report of influenza A that may have caused a profound SIADH-related hyponatraemia.

In recent years viral respiratory tract infections, especially influenza viruses, have had a major impact on communities worldwide as a result of unavailability of effective treatment or vaccine. The frequent alterations in the antigenic structures of respiratory viruses, particularly for RNA viruses, pose difficulties in production of effective vaccines. The unavailability of optimal medication and shortage of effective vaccines suggests the requirement for alternative natural therapies. Several herbal remedies were used for prevention and treatment viral respiratory illnesses. Among those that were found effective included maoto, licorice roots, antiwei, North American ginseng, berries, Echinacea, plants extracted carnosic acid, pomegranate, guava tea, and Bai Shao. There is scientific evidence regarding the effectiveness of several complementary therapies for colds. Oral zinc may reduce the length and severity of a cold. Taking vitamin C supplements on a regular basis only slightly reduces the length and severity of colds. Probiotics were found better than placebo in reducing the number episodes of acute upper respiratory tract infections, the rate of episodes of acute upper respiratory tract infection and reducing antibiotic use. Alkaline diets or drinks might have antiviral properties as in vitro studies demonstrated inactivation effect of alkaline medium on respiratory virus. Earthing might have a natural anti-inflammatory effect for human body. It is now accepted that an overwhelming inflammatory response is the cause of human deaths from avian H5N1 influenza infection. Earthing accelerates immune response following vaccination, as demonstrated by increases of gamma globulin concentration. No in vivo or clinical studies were found that investigate the role of alkalization or earthing on respiratory viral infections. Thus, future studies are recommended to reveal any potential curative effects.

Tract Infections

Acute respiratory tract infections (ARTI) are very common in all age groups. Childhood respiratory tract infections are responsible for considerable morbidity and mortality. It is significant health problem in India also. The World Health Organization (WHO) estimates that 2 million children under five years of age die due to pneumonia. Majority of ARTIs have viral etiology. Rhinoviruses, respiratory syncytial viruses, parainfluenza and influenza viruses, human metapneumovirus, and adenoviruses are main causative agents. Among bacteria, group A streptococci, Corynebacterium diphtheriae, N. meningitides, H. influenzae, pneumococcus and Staphylococcus aureus are responsible for ARTIs. Drug utilization studies help to understand the pattern of prescription in that particular area for specific conditions.We included children from one to five years of age, diagnosed as ARTI and evaluated 298 prescriptions given to these children. Analysis of these prescriptions was done as well as they are compared with WHO prescription indicators. Cough (96%), fever (93%) and rhinitis (82.5%) were common symptoms observed, but sore throat, earache and breathlessness were also present in these children. Average number of drugs prescribed was 4.1/patient. Following drugs were prescribed, Antipyretics 98.3%, antimicrobials 91.3%, antihistaminics and cough syrups in 75.2%, Leukotriene antagonist in 25.1% patients, Vitamin B complex 11% and glucocorticoids 4.6%. All drugs were prescribed by brand names and not by generic name. 97.3% prescribed drugs were from national list of essential medicine. We found overuse of antimicrobials in our study. Educational programs are needed in order to bring rational use of antimicrobials. At the same time awareness in parents also should be done regarding antimicrobial use.
