At the beginning of the COVID-19 in Iran, adequate measures were recommended and taken by the health system to control this epidemic. These interventions can be classified into three main parts: 1) Measures to change the health behaviors of the community and improve self-care; 2) Social distance plans; and 3) Active screening, finding patients and isolating COVID-19 cases, which were not wholly fulfilled.
Carrying out these interventions caused Iran to have acceptable success in the relative control of the first wave of the COVID 19 after a period of initial disorder for several weeks [i]. Despite the efforts made, due to the limited evidence and scientific controversies ,severe sanctions, the most complex etiologies, most rapid spread, and most unpredictable scale, the lack of preparedness of society and the health system, lack of a plan for risk communication and community engagement, the lack of similar experience in the country and internationally, and after too early reopening, challenges arose in the management of the disease and the number of deaths and hospitalized people has been increased for several times. Assessing these challenges in the health system in response to COVID-19 can improve the knowledge of service providers and serve as a primary framework for the planning of the health system to enhance readiness to manage this long-lasting and devastating event and similar situations.
The nature of COVID-19 and the way(s) it is spread globally were unknown, which led to the rapid spread of the disease in countries. The power of transmission in asymptomatic-symptomatic, mild, and severe cases remains unknown. In some cases of COVID-19, we are faced with inconsistencies in laboratory diagnosis with clinical and radiographic findings. In the line of this part of the study results, some studies focusing on unknown nature of the virus and its complex etiologies (10).
In line with this study's findings, other countries also had successful experiences in performing disease management interventions. For example, Qatar has conducted free diagnostic and treatment tests for patients, the developed medical staff, and the necessary equipment, including establishing field hospitals to further prepare for the fight against the disease (11). Iceland, with its precision and speed in taking preventive measures, was able to stabilize after 40 days of the outbreak. Testing of all suspected asymptomatic and symptomatic individuals, people who have had suspicious trips or have been in contact with people suspected of having the disease began a month before the discovering of the first case of the disease in the country (12, 13).
Too early reopening public places and reduce social restrictions and isolation is causing a second wave in some countries like the United State of America, Germany, France and Iran. Moreover, scarce resources and funding allocation decisions must aim to reduce inequities rather than exacerbate them (14).
The other countries with similar challenges have some experiences which can be used to manage the disease; for instance, although Vietnam has a common land border with China and has a high population, the incidence rate of this disease has been low in this country (15). After announcing the outbreak of a disease like Hong Kong (16), Vietnam closed its borders to China and, since the first case of the disease was identified in the country, quarantined all travelers from abroad for 14 days. For this purpose, even hotels were used as a place to quarantine travelers without charge. The cancellation of flights and the ban on the entry of all foreign passengers into the country also began about two months after the outbreak of the epidemic in the country. Vietnam is one of the most prosperous countries in the fight against COVID-19 (15).
The announcement of a nationwide home quarantine for three weeks from March 26, 2020, and the help of police forces to prevent people from leaving their homes, closing cultural and religious centers, stopping the Indian tourism industry, and holding some popular Indian sports such as cricket without spectators were other actions to control the disease (17). Egypt also closed its borders and canceled international flights until April 23, 2020, recessed schools, Universities, sports clubs, and restaurants, closed cultural venues and suspended cultural and artistic activities, suspended mosques and churches, banned collective activities and the holding of Iftar ceremonies during the month of Ramadan and released eligible prisoners to prevent the spread of the disease in the country (18). South Africa has so far been successful in controlling COVID-19 and has used its experience in fighting AIDS to combat COVID-19. The implementation of the quarantine program and its extension until the control of the disease, the performance of the social distance plan, home-to-home screening of people by health personnel, and the prohibition of public gatherings have been among the programs of this country (19).
In Malaysia, a day after the start of the epidemic in the country, visas for travelers from Wuhan and other parts of China were revoked. In total, 107 Malaysians were deported from Wuhan, China, and quarantined for 14 days. Home quarantine was also implemented by restricting traffic except for essential services, reducing the working hours of gas stations, supermarkets and shops, and closing public and private offices, as well as religious rites, in addition to not allowing people to leave their homes in high-risk areas for 14 days (20, 21).
The intensive work of health care providers during COVID-19 physically and emotionally destroyed them (22). Adequate, trained, experienced, responsible, and accountable staff plays an essential role in achieving the health system's goals. A recent study in Iran shows that in terms of the subscale score of NASA-TLX, nurses had more scores in mental pressure, physical pressure, time pressure (temporal), and frustration compared to the other jobs. Moreover, nurses had significantly more workloads compared to other jobs (Shoja, 2020).
Health care workers need to be motivated to provide quality services to the community. Sometimes, due to the lack of evidence and unrealistic self-confidence, health care personnel neglect proper personal protection, which requires monitoring staff performance and support. It is necessary to prepare a database of employees of the health system, retirees, and volunteers and organize them in alternative relief teams.
In this regard, Brazil has listed the benefit of official employees and employers from the short-term work program supported by the government and unemployment insurance and payment of salaries for the first 15 days of sick leave to the employees with positive Coronavirus test. India has also allocated medical insurance for health care providers (23). In Germany, DBfK – Bundesverband has a cooperation with the Federal Chamber of Psychotherapists to provide telephone counseling services to nurses free of charge, and In Taiwan, nurses who have taken care of suspected or confirmed cases of COVID-19 may take an additional three-day and 14-day leave, respectively (24).
Equipment such as personal protective equipment (PPE), ventilators, oxygen, and diagnostic kits should be available (25) Providing the necessary equipment in an emergency by making changes to upstream rules, developing guidelines and transparent processes for Strategic Supply Chain is essential to deal with COVID-
Finally, to manage the next wave of disease, it is recommended to making a clear decision on when to reopen educational centers, monitoring the implementation of social distancing protocols, applying more strictness and seriousness in the field of traffic restrictions, quarantine of contacted and vulnerable people, real-time risk communication with establishing a trustable communication with the people to educate and accompany them for quarantine and social distancing is necessary. Providing appropriate and timely social support for vulnerable groups could decrease the number of infected and dying. Supporting the country to procure vaccine at least for vulnerable groups by international community can help the health system to manage next coming waves or peaks.
