BACKGROUND: With the COVID-19 pandemic, there was an increase and scaling up of provider-to-provider telemedicine programs that connect frontline health providers such as nurses and community health workers at primary care clinics with remote doctors at tertiary facilities to facilitate consultations for rural patients. Considering this new trend of increasing use of telemedicine, this study was conducted to generate evidence for patients, health providers, and policymakers to compare if provider-to-provider telemedicine-based care is equivalent to in-person care and is safe and acceptable in terms of diagnostic and treatment standards...

INTRODUCTION: Acute febrile illnesses (AFI) are a frequent chief complaint in outpatients. Because the capacity to investigate the causative pathogen of AFIs is limited in low- and middle-income countries, patient management may be suboptimal. Understanding the distribution of causes of AFI can improve patient outcomes. This study aims to describe the most common etiologies diagnosed over a 16-years period in a national reference center for tropical diseases in a large urban center in Rio de Janeiro, Brazil...

Viral diseases of the nervous system are ancient and poliomyelitis was described in Egypt as early as 2000 BC. They can cause a wide range of neurological symptoms, such as meningitis, encephalitis, meningoencephalitis, Guillain-Barré-like syndrome and stroke, often leaving mild to severe residuals. Depending on the pathogen, the symptoms appear quickly within hours, or lead to increasing chronic symptoms within 1 week or months. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which was newly identified in January 2020 and occurs worldwide, illustrates the sequelae of a phenomenon that has been known for centuries, the possible rapid spread of pathogen-related infectious diseases...

Multisystem inflammatory syndrome in adults (MIS-A) is an uncommon but severe and still understudied post-infectious complication of COVID-19. Clinically, the disease manifests itself most often 2-6 weeks after overcoming the infection. Young and middle-aged patients are especially affected. The clinical picture of the disease is very diverse. The dominant symptoms are mainly fever and myalgia, usually accompanied by various, especially extrapulmonary, manifestations. Cardiac damage (often in the form of cardiogenic shock) and significantly increased inflammatory parameters are often associated with MIS-A, while respiratory symptoms, including hypoxia, are less frequent...

BACKGROUND: During the COVID-19 pandemic, the use of face masks has been recommended or enforced in several situations, however their effects on physiological parameters and cognitive performance at high altitude are unknown. METHODS: Eight healthy participants (four females) rested and exercised (cycling, 1 W/kg) while wearing no mask, a surgical mask, or a filtering facepiece class 2 respirator (FFP2), both in normoxia and hypobaric hypoxia corresponding to an altitude of 3000 m...

Several tropical or geographically confined infectious diseases may lead to organ failure requiring management in an intensive care unit (ICU), both in endemic low- and middle-income countries where ICU facilities are increasingly being developed and in (nonendemic) high-income countries through an increase in international travel and migration. The ICU physician must know which of these diseases may be encountered and how to recognize, differentiate, and treat them. The four historically most prevalent "tropical" diseases (malaria, enteric fever, dengue, and rickettsiosis) can present with single or multiple organ failure in a very similar manner, which makes differentiation based solely on clinical signs very difficult...

The COVID-19 pandemic was the worst public-health crisis in recent history. The impact of the pandemic in tropical regions was further complicated by other endemic tropical diseases, which can cause concurrent infections along with COVID-19. Here, we describe the clinical course of a patient with concurrent COVID-19 and scrub typhus infection. The patient's de-identified clinical data were retrieved retrospectively. The patient had progressive breathlessness at the time of presentation and was hospitalized for COVID-19...

Patients with respiratory viral infections are more likely to develop co-infections leading to increased fatality. Mucormycosis is an epidemic amidst the COVID-19 pandemic that conveys a 'double threat' to the global health fraternity. Mucormycosis is caused by the Mucorales group of fungi and exhibits acute angioinvasion generally in immunocompromised patients. The most familiar foci of infections are sinuses (39%), lungs (24%), and skin tissues (19%) where the overall dissemination occurs in 23% of cases...

Human monkeypox (MPOX) which recently hit the headlines is a rare, emerging zoonotic disease, only next to smallpox yet never attended adequately to halt the epidemic outbreak threat. MPOX is caused by Orthopox virus , which is a double-stranded, linear DNA virus, transmitted from infected animals, commonly rodents to humans. Monkeypox is endemic to the tropical jungles in Central-West Africa; occasional cases reported in other nations could be due to people traveling from endemic regions of MPOX. Transmission may occur via direct contact with human body secretions, cutaneous or mucosal lesions in the mouth or throat or respiratory droplets, and contaminated objects...

INTRODUCTION: This article aims to discuss all the challenges faced in the diagnosis of coronavirus disease 2019 (COVID-19) in pregnancy, isolation of suspected and positive patients, their management, and the strategies to prevent the transmission of infection among the healthy population and medical fraternity. The diagnosis of COVID in pregnancy is influenced by many factors, including normal physiological changes in pregnancy, comorbid conditions associated with pregnancy, and the presence of asymptomatic infection in patients...

BACKGROUND: Current surveillance of travellers' health captures only a small proportion of illness events. We aimed to evaluate the usability and feasibility of using an app to enable travellers to self-report illness. METHOD: This pilot study assesses a novel mobile application called Infection Tracking in Travellers (ITIT) that records travel-related symptoms with associated geolocation and weather data. Participants were recruited in three Swiss travel clinics between December 2021 and March 2022...

Severe respiratory failure developing in the course of high-altitude pulmonary edema in an alpinist with COVID-19 pneumonia: a case report. High Alt Med Biol . 23:372-376, 2022.-The case of a 38-year-old Polish alpinist, evacuated from base camp (4,200 m) under Lenin's Peak due to severe high-altitude pulmonary edema (HAPE) and symptoms of acute mountain sickness/high-altitude cerebral edema (HACE), is presented. Starting the expedition, the man was asymptomatic and had a negative COVID-19 molecular test...

BACKGROUND: Respiratory and gastrointestinal symptoms and febrile illness are the most common complaints among ill pilgrims attending the Grand Magal of Touba (GMT) in Senegal. METHODS: Patients presenting with respiratory or gastrointestinal symptoms or febrile systemic illnesses were recruited between 2018 and 2021 at a healthcare centre close to Touba. Respiratory, gastrointestinal and blood samples were tested for potential pathogens using qPCR. RESULTS: 538 patients were included...

A 65 year-old gentleman had been brought to our Respiratory Emergency Department for patients with respiratory symptoms and a possible COVID-19 infection with a 3-day history of shortness of breath (SOB), fever, a productive cough of yellow sputum, and right-sided chest pain. The patient had received both vaccinations at the time and initially reported no travel history, although later it was revealed that he had recently stayed at a hotel. He tested positive for COVID-19 and had hyponatremia and a raised procalcitonin, indicating a bacterial infection as well...

Human monkeypox is an emerging zoonotic disease caused by a monkeypox virus. The monkeypox virus history originated in 1958 after the occurrence of a pox-like illness in monkeys. In September 1970, the first case of human monkeypox was identified in the Democratic Republic of Congo, Africa. This year, from January 01, to September 30, 2022, the virus swiftly spread from endemic to non-endemic counties, involving 106 states, infecting 68,017 people; 689 cases from 07 endemic African countries and 67,328 cases in 99 non-endemic countries in Europe, America, Asia and Oceania continents...

BACKGROUND: Recent studies on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reveal that Omicron variant BA.1 and sub-lineages have revived the concern over resistance to antiviral drugs and vaccine-induced immunity. The present study aims to analyze the clinical profile and genome characterization of the SARS-CoV-2 variant in eastern Uttar Pradesh (UP), North India. METHODS: Whole-genome sequencing (WGS) was conducted for 146 SARS-CoV-2 samples obtained from individuals who tested coronavirus disease 2019 (COVID-19) positive between the period of 1 January 2022 and 24 February 2022, from three districts of eastern UP...

Background: Since the first case reported in December 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused an outbreak of coronavirus disease 2019 (COVID-19) worldwide. The global case count continued to rise and the WHO declared a Public Health Emergency of International Concern (PHEIC), causing a growing risk of imported COVID-19 infection. This study aimed to provide descriptive and quantitative epidemiological characteristics of imported COVID-19 cases in China...

With increasing travel and immunosuppression, parasitic lung and pleural diseases are increasingly been reported. The diagnosis in certain cases is very challenging because of nonspecific clinical and radiological features. We hereby present a case of a 60-year-old immunocompetent female complaining of difficulty in breathing for 4-5 days for which sputum sample along with the coughed-up fragment of the parasite under investigation was sent to the laboratory. All the blood parameters along with blood and sputum culture were within normal limits...
