Acute respiratory viral infections (ARVI), including influenza, remain the most common infectious diseases. In the context of COVID‑19 pandemic, there is a need for differential diagnosis of respiratory syndrome. The clinic of ARVI, depending on the pathogen, may have its own characteristics. Influenza and COVID‑19 have common pathways of transmission of the pathogen and similar symptoms, so the optimal differential diagnosis is the use of test systems for both viruses. Against the background of influenza and other acute respiratory infections, complications from various organs and systems can develop. The article discusses in detail the issues of the clinical course of ARVI, differential diagnosis, modern approaches to therapyand prophylactic. Complications of influenza from the cardiovascular system are considered in detail. The data of our own observations on the risk of developing acute coronary syndrome in persons who have undergone COVID‑19 are presented. Prevention of the development of complications of influenza and other acute respiratory infections is the early appointment of antiviral therapy. Numerous studies confirm the effectiveness of interferon inducers in the treatment of influenza and other ARVI. The article presents the results of clinical studies confirming the effectiveness of therapy with the interferon inducer Kagocel. Against the background of its use, a decrease in the severity of clinical manifestations, a reduction in the duration of the disease, and the prevention of complications were noted. In studies, the drug has shown a high level of safety. The article discusses studies on the effectiveness of chemoprophylaxis of influenza and other acute respiratory infections.
Over the past period of the COVID‑19 pandemic, experience has been gained on the ways of spreading the infection, new approaches to treatment have been formed, and preparations for vaccine prevention have been created. Information about COVID‑19 is updated with new data on the features of the clinical course, including rare manifestations of the disease. The clinical symptoms of CAVID‑19 are characterized by a significant variety and are due to the tropism of the SARS‑CoV‑2 virus to various tissues. The article describes a clinical case of COVID‑19. With severe intoxication syndrome, the patient was found to have concomitant acute tonsillitis. The article provides a review of the literature on the clinical symptoms of COVIND‑19 and the mechanisms of their development. The differential diagnosis of viral and bacterial tonsillitis is considered. Efficacy of antibacterial therapy of tonsillitis with cefixime. The clinical case is illustrated with photos.
Influenza remains one of the most common respiratory viral diseases with a high risk of complications. In the context of the COVID-19 pandemic, there is a possibility of simultaneous circulation of two viruses, which makes it necessary to conduct a differential diagnosis. Influenza and COVID-19 have common pathways of transmission of the pathogen and similar symptoms, so the optimal differential diagnosis is the use of test systems for both viruses. Against the background of influenza and COVID-19, complications from various organs and systems can develop. The article describes in detail the complications of influenza from the cardiovascular system. After infection with the flu virus, there is a 6-to 10-fold increase in the risk of acute myocardial infarction and a 3 - to 8-fold increase in the risk of stroke. COVID-19 is associated with arterial hypertension, diabetes mellitus, cardiac arrhythmias, myocarditis, high risk of acute myocardial infarction, and heart failure. The article presents the data of our own research, indicating that the transferred COVID-19 disease increases the risk of acute coronary syndrome, regardless of the presence of risk factors for cardiovascular events. Prevention of the development of influenza complications is the early administration of etiotropic antiviral therapy. Numerous studies confirm the effectiveness of the neuraminidase inhibitor oseltamivir in the treatment of influenza. The use of oseltamivir reduces the severity of clinical manifestations, reduces the duration of the disease, reduces the risk of complications and death. The most effective measure to prevent influenza and COVID-19 is specific immunization. In some cases, chemoprophylaxis can be used. The article discusses studies on the effectiveness of influenza chemoprophylaxis with the use of neuraminidase inhibitors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
