SARS-CoV-2 primarily affects a person's respiratory system and leads to the spread of pathogenicity in the person and therefore this study evaluated the Case Fatality Rate (CFR) and Basic Reproductive Rate (R-naught) of COVID-19.
This cross-sectional descriptive study was performed on all people with COVID-19 from the first date of admission of positive PCR patients with SARS-CoV-2 until September 21, 2020, in the area of Markazi Province in Khomein, Iran. Information on the records of definitively discharged and deceased patients due to COVID-19 (having positive PCR) was extracted from 20/2/2020 to 21/9/2020, and Case Fatality Rate (CFR) and Basic Reproductive Rate (R-naught) of COVID-19 were evaluated. The sample size was 691 people.
The CFR of the COVID-19 in the current study is 6.65%, and the rate of disease transmission among the sensitive population of Khomein city at the beginning of the study (March) averaged BASIC REPRODUCTIVE RATE= 1.75, and in the last month (September) of the study This value was reduced to BASIC REPRODUCTIVE RATE= 1.306.
According to our study on Case Fatality Rate (CFR) and Basic Reproductive Rate (R-naught) of COVID-19, showed that the prevalence of the disease was high in March, which due to lack of proper observance of health protocols, we saw this problem and in the months when people have more problems. Hygiene was reduced, and the rate of transmission and mortality was reduced.
严重急性呼吸综合征冠状病毒2（SARS-CoV-2）主要影响人的呼吸系统，并导致病原体在人体内传播，因此本研究评估了新型冠状病毒肺炎（COVID-19）的病死率（CFR）和基本繁殖数（R0）。
本横断面描述性研究针对2020年2月20日至9月21日期间伊朗霍梅因马卡齐省地区所有感染COVID-19的患者开展，这些患者自SARS-CoV-2核酸检测呈阳性并入院首日起纳入研究。从2020年2月20日至9月21日提取确诊出院和因COVID-19死亡（核酸检测呈阳性）患者的记录信息，并评估COVID-19的病死率（CFR）和基本繁殖数（R0）。样本量为691人。
本研究中COVID-19的病死率为6.65%，研究开始时（3月）霍梅因市易感人群中的疾病传播率平均基本繁殖数为1.75，在研究的最后一个月（9月）该值降至基本繁殖数为1.306。
根据我们对COVID-19的病死率（CFR）和基本繁殖数（R0）的研究表明，3月疾病患病率较高，这是由于缺乏对卫生协议的适当遵守，我们发现了这个问题，并且在人们卫生习惯较差的几个月里，传播率和死亡率都有所降低。
