Since the beginning of COVID-19, more than 13,036,550 people have been infected, and 571,574 died because disease by July 13, 2020. Developing new methodologies to predict COVID-19 pandemic will help policymakers plan contain spread virus. In this research, we develop a Stochastic Fractal Search algorithm combined with mathematical model forecast pandemic. To enhance algorithm, employed design experiments approach for tuning. We applied our public datasets in Canada upcoming months. Our predicts number symptomatic, asymptomatic, life-threatening, recovered, death cases. The outcomes reveal that asymptomatic cases play main role transmission also show increasing testing capacity would detection limit community transmission. Moreover, performed sensitivity analyses discover effects changes rates on growth. provide realistic overview future if change due emergence variants or social measures.

The COVID-19 pandemic continues to have major impact health and medical infrastructure, economy, agriculture. Prominent computational mathematical models been unreliable due the complexity of spread infections. Moreover, lack data collection reporting makes modelling attempts difficult unreliable. Hence, we need re-look at situation with reliable sources innovative forecasting models. Deep learning such as recurrent neural networks are well suited for spatiotemporal sequences. In this paper, apply long short term memory (LSTM), bidirectional LSTM, encoder-decoder LSTM multi-step (short-term) infection forecasting. We select Indian states hotpots capture first (2020) second (2021) wave infections provide two months ahead forecast. Our model predicts that likelihood another in October November 2021 is low; however, authorities be vigilant given emerging variants virus. accuracy predictions motivate application method other countries regions. Nevertheless, challenges remain reliability difficulties capturing factors population density, logistics, social aspects culture lifestyle.

COVID-19 is the disease evoked by a new breed of coronavirus called severe acute respiratory syndrome 2 (SARS-CoV-2). Recently, has become pandemic infecting more than 152 million people in over 216 countries and territories. The exponential increase number infections rendered traditional diagnosis techniques inefficient. Therefore, many researchers have developed several intelligent techniques, such as deep learning (DL) machine (ML), which can assist healthcare sector providing quick precise diagnosis. this paper provides comprehensive review most recent DL ML for studies are published from December 2019 until April 2021. In general, includes 200 that been carefully selected publishers, IEEE, Springer Elsevier. We classify research tracks into two categories: present public datasets established extracted different countries. measures used to evaluate methods comparatively analysed proper discussion provided. conclusion, diagnosing outbreak prediction, SVM widely mechanism, CNN mechanism.

The first known case of Coronavirus disease 2019 (COVID-19) was identified in December 2019. It has spread worldwide, leading to an ongoing pandemic, imposed restrictions and costs many countries. Predicting the number new cases deaths during this period can be a useful step predicting facilities required future. purpose study is predict rate one, three seven-day ahead next 100 days. motivation for every n days (instead just day) investigation possibility computational cost reduction still achieving reasonable performance. Such scenario may encountered real-time forecasting time series. Six different deep learning methods are examined on data adopted from WHO website. Three LSTM, Convolutional GRU. bidirectional extension then considered each method forecast Australia Iran This novel as it carries out comprehensive evaluation aforementioned their extensions perform prediction COVID-19 death To best our knowledge, that Bi-GRU Bi-Conv-LSTM models used presented form graphs Friedman statistical test. results show have lower errors than other models. A several error metrics compare all models, finally, superiority determined. research could organisations working against determining long-term plans.

Today, artificial intelligence (AI) and machine learning (ML) have dramatically advanced in various industries, especially medicine. AI describes computational programs that mimic simulate human intelligence, for example, a person’s behavior solving problems or his ability learning. Furthermore, ML is subset of intelligence. It extracts patterns from raw data automatically. The purpose this paper to help researchers gain proper understanding its applications healthcare. In paper, we first present classification learning-based schemes According our proposed taxonomy, healthcare are categorized based on pre-processing methods (data cleaning methods, reduction methods), (unsupervised learning, supervised semi-supervised reinforcement learning), evaluation (simulation-based practical implementation-based real environment) (diagnosis, treatment). classification, review some studies presented We believe helps familiarize themselves with the newest research medicine, recognize their challenges limitations area, identify future directions.

SARS-CoV-2 virus infections in humans were first reported December 2019, the boreal winter. The resulting COVID-19 pandemic was declared by WHO March 2020. By July 2020, present 213 countries and territories, with over 12 million confirmed cases half a attributed deaths. Knowledge of other viral respiratory diseases suggests that transmission could be modulated seasonally varying environmental factors such as temperature humidity. Many studies on sensitivity are appearing online, some have been published peer-reviewed journals. Initially, these raised hypothesis climatic conditions would subdue rate places entering summer, southern hemisphere experience enhanced disease spread. For latter, peak coincide influenza season, increasing misdiagnosis placing an additional burden health systems. In this review, we assess evidence drivers significant factor trajectory pandemic, globally regionally. We critically assessed 42 80 preprint publications met qualifying criteria. Since has prevalent for only year northern, one-quarter hemisphere, datasets capturing full seasonal cycle one locality not yet available. Analyses based space-for-time substitutions, i.e., using data from climatically distinct locations surrogate progression, inconclusive. strong northern bias. Socio-economic peculiar to 'Global South' omitted confounding variables, thereby weakening signals. explore why research date failed show convincing modulation COVID-19, discuss directions future research. conclude thus far weak effect, currently overwhelmed scale spread COVID-19. Seasonally transmission, if it exists, will more evident 2021 subsequent years.

Abstract The Covid‐19 pandemic has emerged as one of the most disquieting worldwide public health emergencies 21st century and thrown into sharp relief, among other factors, dire need for robust forecasting techniques disease detection, alleviation well prevention. Forecasting been powerful statistical methods employed world over in various disciplines detecting analyzing trends predicting future outcomes based on which timely mitigating actions can be undertaken. To that end, several machine learning have harnessed depending upon analysis desired availability data. Historically speaking, predictions thus arrived at short term country‐specific nature. In this work, multimodel technique is called EAMA related parameters long‐term both within India a global scale proposed. This proposed hybrid model well‐suited to past present For study, two datasets from Ministry Health & Family Welfare Worldometers, respectively, exploited. Using these datasets, data outlined, observed predicted being very similar real‐time values. experiment also conducted statewise countrywise across it included Appendix.
