The outbreak of the novel COVID-19 in December 2019 in Wuhan, China, posed numerous challenges across multiple sectors globally. Even developed countries, despite having advanced health and social welfare systems, have faced difficulties in recent years (
1). Other countries that officially reported COVID-19 cases after China have often attributed the spread and infection to human-to-human transmission via air travel and cross-border movement (
2). As the disease rapidly spread across continents, the World Health Organization (WHO) declared COVID-19 a global health emergency in March 2020, intensifying international concerns (
3). The WHO also called for early diagnosis, isolation, and treatment of patients, contact tracing, and social distancing to break the chain of virus transmission (
4). According to WHO data, as of June 17, 2022, over 535 million confirmed cases and more than 6.3 million deaths have been reported worldwide (

COVID-19 has had significant economic impacts on countries. Direct and indirect medical costs, increased hospital admissions, loss of income, and a decline in gross domestic product (GDP) are among these effects. The economic burden of this disease has placed substantial pressure not only on health systems but also on national economies. This study aims to estimate the economic burden of COVID-19 at Abadan University of Medical Sciences so that health system policymakers and planners can allocate resources more efficiently based on these results. Today, according to studies conducted by international organizations and research centers, the COVID-19 pandemic is not only a health threat but also a socioeconomic challenge. Changes in daily life and economic interactions attest to this claim (

Regarding the impact of this disease on Iran’s economy, it should be noted that Iran is a middle-income country with a significant portion of its population employed in the informal sector (
7-
9). Despite struggling against the effects of harsh US sanctions in various economic, trade, and medical dimensions, Iran’s achievements in managing and combating the COVID-19 crisis have been commendable, demonstrating the dedication of medical and healthcare staff and the mobilization of available national resources (

One of the main concerns is the extent to which COVID-19 has negatively impacted each country’s economy. From an economic perspective, the outbreak of COVID-19, the increasing number of patients, and the complications arising from this disease have imposed substantial direct and indirect medical costs on individuals, the health system, and the government (
10,
11). Direct medical costs vary depending on the number of infected individuals, disease severity, average hospital stay, ICU admission rates, and other factors (
11,
12). Research suggests that the medical expenses for COVID-19 patients are significantly higher than those for other infectious diseases, mainly due to increased hospitalization rates and mortality risks. A study on 138 COVID-19 patients in Wuhan, China, found that 26.1% received intensive care, with 41.6% receiving non-invasive ventilation and 47.2% requiring invasive ventilation (
13). In Lombardy, Italy, 88% of ICU-admitted patients required invasive ventilation, while 11% received non-invasive ventilation (
14). The daily cost of ICU hospitalization is generally three to four times higher than general ward expenses (
15). Additionally, lost income due to illness, mandatory home quarantine, or workforce death due to infection can be considered significant indirect costs (
16-
18). The spread of COVID-19 and the shutdown of many industries have severely impacted global economic performance, contributing to GDP declines (
19,
20). According to studies, the worldwide spread of COVID-19 has led to a monthly reduction of approximately 2.5% to 3% in global GDP (
21). Furthermore, the COVID-19 outbreak has disproportionately affected the fifteen largest economies worldwide, amplifying financial strain (
