چکیده
در سال­های اخیر بیماری کووید-19 بهعنوان یک بیماری مسری با قدرت انتشار بالا اثرات بسیار مخربی بر جوامع انسانی داشتهاست. از این رو، بررسی نحوۀ انتشار و انتقال آن ضرورت دارد. هدف از پژوهش حاضر، تخمین احتمال انتقال ویروس کرونا و پیش­بینی سرایت آن با استفاده از روش تصادفی زنجیره­های مارکوف است. برای این منظور به مدل‌سازی انتشار ویروس کرونا در کشورهای فرانسه، انگلستان، آلمان، ایران و نیجریه پرداخته شدهاست. باتوجهبه نتایج، بیشترین احتمال انتقال این ویروس مربوطبه کشور فرانسه است که با گذشت زمان بهسرعت کاهش یافتهاست. علاوهبر این، موارد ابتلای پیش­بینیشده در سال 2021 برای کشورهای انگلیس، آلمان و ایران بهترتیب بهاندازۀ 1.2، 1.8 و 0.7 درصد با مقادیر گزارششده، اختلاف دارد. این نتایج بیانگر کارایی مدل پیشنهادی در پیش­بینی تعداد افراد مبتلا به ویروس کروناست.

چکیده English

In recent years, Covid-19 disease, as a contagious disease with high spreading power, has had very destructive effects on human societies. Therefore, it is necessary to investigate how it is spread and transmitted. The aim of the current research is to estimate the probability of transmission of the coronavirus and to predict its spread using the random method of Markov chains. For this purpose, the spread of the coronavirus in France, England, Germany, Iran and Nigeria has been modeled. According to the results, the highest probability of transmission of this virus is related to France, which has decreased rapidly over time. In addition, the cases predicted in 2021 for England, Germany and Iran are 1.2%, 1.8% and 0.7% different from the reported values, respectively. These results show the effectiveness of the proposed model in predicting the number of people infected with the coronavirus.
