Sentiment Analysis of Corona Vaccination on Twitter Data using Machine Learning Techniques

Currently, most of the people are stating their opinion through social media. Public opinion stands an important one while reviewing any product, Movie etc. The field of opinion mining has turn out to be the most significant areas of Natural Language Processing. Opinion mining can be used to make decisions about the product or Movie centred on the reviews given by customers in social media. Twitter is one of the most popular social media platforms;Twitter allows users to express their opinions through tweets. It is vital to use these reviews to make decisions and manage the situation. This paper examines public opinions regarding Corona vaccination during pandemic situations with the goal of exploring the opinions of people. In this work, opinion mining of tweets posted by users in Twitter regarding corona vaccination has been performed using Machine Learning Models and Lexicon based approach. Data are collected from Twitter through Tweepy API, and it is pre-processed using NLTK library using python. A comparison of eleven different classification algorithms is made to determine which the best is. As a result, we can conclude that people support neutral decision to take Corona vaccine during the current pandemic. © 2022 IEEE.

A Review On Covid-19 Vaccines and its Hesitancy

The COVID-19 pandemic was caused by the virus namely Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2), has caused a substantial loss not only to human lives but also to public, healthcare systems and global economy. The vaccine development is the crucial process which helps to end the covid-19 pandemic. The preliminary data from trials shows that the covid-19 vaccine is safe as well as effective. However, the acceptance of the COVID-19 vaccine among the public depends on various factors. The primary aim of the study is to examine the factors that promote vaccine acceptance or hesitancy and strategies to overcome hesitation thereby to improve vaccine acceptance among public.

Discussed herein are facts about the aetiological agent, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), phases of the pandemic, magnitude of the pandemic in China and in India, and its global spread, measures put in place to control disease transmission such as screening of travellers, contact tracing, testing, home quarantine, and lockdowns, strategy for COVID-19 testing in India, course and outcome of COVID-19. In addition, several other topics are discussed such as providing health care to COVID-19 patients, guidelines for management of infected persons, home-based care for persons with mild infections, hospitalisation for moderate and severe cases, care of vulnerable segments of population with COVID-19, health care for persons not having COVID-19, nutrition support to persons with COVID-19, Nutrition support to general population during COVID-19 epidemic, preventing the rise of overnutrition during the COVID-19 epidemic. Furthermore, discussed here as well are topics such as COVID-19 and mental health, personal protection measures, handwashing and sanitising surfaces, wearing of masks, personal protective equipment for health care workers. Lastly, the adverse impact of COVID-19 on quality of life is discussed as well, particularly aspects such as human cost of lockdown, its effect on the economy, food supply, food security, and food safety.

Critically ill COVID-19 patients attended by anesthesiologists in northwestern Spain: A multicenter prospective observational study

Background and objectives There is limited information on outcome, complications and treatments of critically ill COVID-19 patients requiring admission to an intensive care unit (ICU). The aim of this study is to describe the clinical ICU course, treatments used, complications and outcomes, of critically ill COVID-19 patients admitted in seven ICU in Galicia region during the 2020 March–April pandemic peak. Methods Between March 21 and April 19, 2020, we evaluated critically ill COVID-19 patients admitted to the ICU of Anesthesia of seven hospitals in Galicia, northwestern Spain. Outcome, complications, and treatments were monitored until May 6, 2020, the final date of follow-up. Results A total of 97 critically ill COVID-19 patients were included. During ICU stay, mechanical ventilation became necessary in 80 (82.5%) patients, and tracheostomy in 22 (22.7%) patients. Prone position was used frequently in both intubated (67.5%) and awake (27.8%) patients. Medications consisted of antivirals agents (92.7%), corticosteroids (93.8%), tocilizumab (57.7%), and intermediate or high doses of anticoagulants (83.5%). The most frequent complications were ICU-acquired infection (52.6%), thrombosis events (16.5%), and reintubation (9.3%). After a median follow-up of 42 (34–45) days, 15 patients (15.5%) deceased, 73 patients (75.2%) had been discharged from ICU, and nine patients (9.3%) were still in the ICU. Conclusions A high proportion of our critically ill COVID-19 patients required mechanical ventilation, prone positioning, antiviral medication, corticosteroids, and anticoagulants. ICU complications were frequent, mainly infections and thrombotic events. We had a relatively low mortality of 15,5%. Resumen Antecedentes y objetivos Existe poca información sobre la evolución, complicaciones y los tratamientos recibidos por los pacientes críticos con COVID-19 que requieren ingreso en una unidad de cuidados intensivos (UCI). El objetivo de este estudio es describir la evolución clínica, los tratamientos utilizados, las complicaciones y resultados de pacientes críticos COVID-19 ingresados en siete UCI de Anestesiología en la Región de Galicia durante el pico de la pandemia en marzo-abril 2020. Métodos Entre el 21 de marzo y el 19 de abril de 2020 evaluamos todos los pacientes críticos COVID-19 ingresados en las UCI de Anestesiología de siete hospitales en Galicia, en el Noroeste de España. Los resultados, complicaciones y los tratamientos administrados se registraron hasta el 6 de Mayo de 2020, fecha final del seguimiento. Resultados Un total de 97 pacientes críticos COVID-19 fueron incluidos. Durante su estancia en UCI, 80 pacientes (82,5%) necesitaron ventilación mecánica, y 22 pacientes (22,7%) traqueotomía. El decúbito prono se usó frecuentemente en pacientes intubados (67,5%) y despiertos (27,8%). Las medicaciones usadas fueron antivirales (92,7%), corticoides (93,8%), tocilizumab (57,7%), y dosis intermedias y altas de anticoagulantes (83,5%). Las complicaciones más frecuentes fueron infecciones adquiridas en UCI (52,6%), eventos trombóticos (16,5%), y reintubationes (9,3%). Tras un seguimiento medio de 42 (34–45) días, 15 pacientes fallecieron (15,5%), 73 pacientes (75,2%) habían sido dados de alta de UCI y nueve pacientes (9,3%) permanecían todavía en la unidad. Conclusiones Un alto porcentaje de nuestros pacientes críticos COVID-19 requirieron ventilación mecánica, posición prona, medicaciones antivirales, corticoides y anticoagulantes. Las complicaciones en UCI fueron frecuentes, principalmente infecciones y eventos trombóticos. Tuvimos una mortalidad relativamente baja del 15,5%.
