Abstract

  SARS-CoV-2 emerging from Wuhan, China is a member of the Coronaviridae family, which has so far infected and killed many people. The SARS-CoV-2 pandemic affected various aspects of life in Iran and Worldwide, and governments have imposed quarantines and travel bans on an unprecedented scale. The virus causes COVID-19, which can spread through close contact with the infected person, contaminated equipment, and suspended air droplets. The most common symptoms of the disease include fever, cough, shortness of breath, gastrointestinal symptoms, and diarrhea. In severe cases, the lung infection can occur, which causes Severe Acute Respiratory Syndrome that leads to ICU admission and even death.
  Besides, this infection can cause gastrointestinal, neurological, and renal impairments. Not merely, this new coronavirus has infected many more people worldwide in comparison to MERS and SARS, but also it has killed more people. Patients with underlying diseases such as hypertension, diabetes, respiratory problems, kidney disease, heart disease and Immunodeficiency are at higher risk of infection and potential death. Also, the risk of death and complication increases in older adults, while most of the infected children are asymptomatic. Some infected people may have mild or no symptoms but can still transmit the disease and spread it to others.
To diagnose COVID-19, serology tests, and level of ESR, CRP and other acute-phase reactants are helpful, whereas molecular tests, such as RT-PCR tests, that detect the virus’s genetic material are still the golden standard. Also, CT scan detects lung involvement; Ground-glass opacification, especially in lower lobes and subpleural region, is the most common CT characteristic, although it is not specific for COVID-19. Because the disease is difficult to diagnose, hard to prevent and challenging to treat, it has become a major concern for many countries. This review aims to gather existing information in the fields of virology, molecular pathogenesis, disease symptoms, epidemiology, clinical presentations, diagnosis, treatment, and the spread of the disease. This study also provides evidence-based prevention and treatment strategies for health policymakers, doctors, nurses, and practitioners in the field of public health, including researchers and students.

Abstract

The development of industry and technology, changes in agriculture, trade and global travel, and the adaptation of microorganisms are important factors in the occurrence of emerging diseases. Currently, the world is facing a pandemic caused by an emerging virus called the novel coronavirus (Covid 19) in 2020. This disease led to infect more than one million people worldwide and the death of more than five hundred thousand people during six months. Covid 19 causes death in patients with respiratory problems of varying severity. Fever, soreness, dry coughs, shortness of breath, runny nose, and nasal congestion were observed in coronavirus-infected individuals. Fever was one of its common symptoms. Other unusual signs such as diarrhea and nausea were reported for this disease. For the first time, the bat was introduced as the host of the novel coronavirus in China. Therefore, identifying the initial route of transmission of the novel coronavirus is necessary to prevent the occurrence and its widespread distribution. The virus enters into a human through respiratory particles as well as touching the surfaces contaminated by nasal, mouth and eye secretions. Viruses are obligate intracellular pathogens needing host cells to survive. These microorganisms cannot proliferate in foods and require live cells for existence. Food is introduced as a carrier of viruses to the consumer. There have been no reports of novel coronavirus transmission through food. However, it is important to observe the principles of health and safety by assuming the spread of the virus due to food contamination. Regarding the presence and proliferation of novel coronavirus in the gastrointestinal tract and aerosol formation of this microorganism in the feces and the possibility of re-transmitting it to people from various environmental sources, the most important priority is to remove the virus from food environments. It is also important to update the methods of disinfecting surfaces, especially areas with high contact of hand as well as personal hygiene. Therefore, it is recommended to educate the staff about managing the novel coronavirus and improving health guidelines. Furthermore, keeping distance and washing hands is in priority in different food-related environments.

Abstract

Background: The advent of Severe Acute Respiratory Syndrome Coronavirus 2 (so-called SARS-CoV-2) causing Coronavirus Disease 2019 (so-called COVID-19) occurred in Dec. 2019 in Wuhan, China. Having an inconceivable worldwide contagion, the outbreak was labeled a pandemic by the WHO. Dental services and related professions (including dentists, dental assistants, dental hygienists and the personnel of cleansing, remedial, triage, dental laboratories, radiographic laboratories and other related paraclinicals), facing galore aerosol and droplets, are in the topmost risk groups exposed to the queer virus. This study was fulfilled to round up evidence-based data to break a link at any part of the virus transmission chain in dental services and related professions.
Methods: Relevant online databases, as PubMed, MEDLINE, Embase, Scopus, Google Scholar and TripDatabase were searched meticulously and evaluated for relevant published original research papers. Subsequently, to fulfill the investigation, ADA, CDC and WHO websites were reviewed to gain relevant guidelines and protocols. Consequently, 476 resources were included considering the canonical inclusion criteria. For the sake of quality assessment of the resources, an authentic checklist was exploited to score the resources from 1 to 15, wherein the admissible score was 10. After deliberation of resources, 366 of them were excluded and finally, 110 resources were selected and overhauled to attain a comprehensive perception on the subject of the investigation.
Results: Transmission of SARS-CoV-2 includes direct transmission (via droplet and aerosol inhalation) and indirect transmission (via surface and instrument contamination), which can amply occur in dental services and related professions. Therefore, an all-inclusive evidence-based miscellany was rallied on several exigent topics, containing genuine esteem in reputable scientific authorities, to present a consummate report for the dental clinicians and related practitioners, working in the course of the running pandemic.
Conclusion: Contemplating the ongoing crisis, undertaking a set of miscellany elected guidelines and protocols, is indispensable in this vital interval of history to bridle the current pandemic, which has been abridged via this systematic perusal.

Abstract

Background: The clinical field has vast sick data that has not been analyzed. Discovering a way to analyze this raw data and turn it into an information treasure can save many lives. Using data mining methods is an efficient way to analyze this large amount of raw data. It can predict the future with accurate knowledge of the past, providing new insights into disease diagnosis and prevention. Several data mining methods exist but finding a suitable one is very important. Today, coronavirus disease (COVID-19) has become one of the causing deadly diseases in the world. The early diagnosis of pandemic coronavirus disease has a significant impact in preventing death. This study aims to extract the key indications of the disease and find the best data mining methods that enhance the accuracy of coronavirus disease diagnosis.
Methods: In this study, to obtain high accuracy in diagnosing COVID-19 disease, a complete and effective workflow over data mining methods was proposed, which includes these steps: data pre-analyzing, indication selection, model creation, the measure of performance, and display of results. Data and related indications of patients with COVID-19 were collected from Kerman Afzalipour Hospital and Rafsanjan, Ali Ebn Abi Taleb Hospital. Prediction structures were made and tested via different combinations of the disease indications and seven data mining methods. To discover the best key indications, three criteria including accuracy, validation and F-value were applied and to discover the best data mining methods, accuracy and validation criteria were considered. For each data mining method, the criteria were measured independently and all results were reported for analysis. Finally, the best key indications and data mining methods that can diagnose COVID-19 disease with high accuracy were extracted.
Results: 9 key indications and 3 data mining methods were obtained. Experimental results show that the discovered key indications and the best-operating data mining method (i.e. SVM) attain an accuracy of 83.19% for the diagnosis of coronavirus disease.
Conclusion: Due to key indications and data mining methods obtained from this study, it is possible to use this method to diagnose coronavirus disease in different people of different clinical indications with high accuracy.
