Understanding these health trends is crucial for both residents and international visitors, as it sheds light on the nation's public health priorities and the significant strides made in improving the well-being of its population.

Historically, infectious diseases were the primary cause of mortality in Iran, posing a significant burden on the healthcare system. However, thanks to remarkable advancements in health standards, robust national surveillance systems, and dedicated efforts over the past two decades, there has been a notable shift in the leading causes of death. This transformation highlights Iran's commitment to public health and its success in mitigating some of the most devastating health threats.

The Shifting Sands of Health: From Infectious to Non-Communicable Diseases in Iran

For decades, infectious diseases were the dominant health challenge, responsible for the majority of deaths across Iran. However, the landscape of public health has undergone a significant transformation. The success of improved sanitary measures and effective national surveillance systems has led to a remarkable shift in the causes of death, moving away from communicable diseases towards non-communicable diseases (NCDs). This paradigm shift is a testament to the country's progress in public health infrastructure and preventive strategies. While this transition signifies progress in many areas, it also presents a new set of complex challenges that the Iranian healthcare system must address.

The Rise of Non-Communicable Diseases: A New Health Frontier

Today, non-communicable diseases like cardiovascular disorders and cancer are currently the most widespread and harmful diseases in Iran. This rise reflects a global trend often associated with lifestyle changes, urbanization, and an aging population. The focus of public health efforts has increasingly shifted towards understanding and mitigating the risk factors associated with these chronic conditions. Investigating NCDs’ risk factors and tackling them head-on is a critical priority for the Ministry of Health and Medical Education. This involves comprehensive strategies that encompass public awareness campaigns, early detection programs, and the provision of advanced medical care to manage these complex conditions effectively.

Cardiovascular Disease: Iran's Silent Killer

Among the myriad of non-communicable diseases, cardiovascular disease (CVD) stands out as the most common and devastating, killing an estimated 100,000 Iranians each year. This makes CVD a leading cause of mortality and a significant public health concern. The burden of CVD in Iran has dramatically increased over the past 40 years, shifting from infectious and diarrheal diseases in the 1960s to CVD becoming the predominant cause of death a few decades ago. CVD mortality has seen a substantial rise, underscoring the urgent need for targeted interventions. Furthermore, chronic kidney disease also poses a serious health threat to the entire nation, contributing to the overall burden of NCDs. Addressing these chronic conditions requires a multi-faceted approach, including promoting healthy lifestyles, managing risk factors such as hypertension and diabetes, and ensuring access to quality cardiac and renal care.

Persistent Threats: Understanding Infectious Diseases in Iran

Despite the significant decrease in the incidence of infectious diseases, particularly parasitic ones, in Iran in recent years, they continue to be one of the most important public health problems in the Eastern Mediterranean Region, including the Islamic Republic of Iran. Some infectious diseases, such as HIV/AIDS, tuberculosis (TB), viral hepatitis, and pneumonia, still take lives today. Others, such as diarrhoeal diseases and leishmaniasis, also pose ongoing challenges. The fight against these diseases requires continuous vigilance, improved sanitation, active surveillance, comprehensive infection control strategies, and monitoring the appropriate use of antibiotics. These measures are indispensable to prevent a resurgence and to further reduce their impact on the population.

Hepatitis: A Common Concern for Travelers and Residents

Hepatitis, a liver disease, is particularly prevalent among the diseases in Iran. The Center for Disease Control and Prevention (CDC) recommends being vaccinated for Hepatitis A and Hepatitis B before traveling to the Middle East, due to it being one of the most common diseases in Iran. Hepatitis A, specifically, is spread by consuming contaminated food or water and can cause symptoms such as fever, tiredness, nausea, vomiting, and stomach pain. This highlights the importance of practicing good hygiene and being mindful of food and water sources, especially for travelers. The continued presence of viral hepatitis underscores the need for ongoing vaccination campaigns and public health education to prevent its spread and protect vulnerable populations.

Zoonotic Diseases: The Human-Animal Health Interface

Beyond the more commonly known infectious diseases, Iran also faces challenges from zoonotic diseases, which are transmitted from animals to humans. Other emerging and re-emerging infectious diseases (EIDs and RIDs) in Iran include zoonotic diseases such as leptospirosis, glanders, hantaviruses, and Middle East Respiratory Syndrome (MERS). Controlling these aforementioned diseases necessitates a close collaboration between the Ministry of Health and the Veterinary Organization, since animals are the main reservoirs of these diseases. This "One Health" approach is crucial for effective prevention and control, involving coordinated efforts in surveillance, diagnosis, and public health interventions at the human-animal interface. The Research Centre for Emerging and Re-emerging Infectious Diseases at the Pasteur Institute of Iran, with its National Reference Laboratory for Plague, Tularemia, and Q Fever, plays a vital role in this collaborative effort.

Tackling Communicable Diseases: Strategies and Successes

The Iranian government, through its Ministry of Health and Medical Education, has implemented robust strategies to combat communicable diseases. While the incidence and prevalence of many infectious diseases have decreased significantly, especially parasitic ones, the fight is far from over. Sustained community spread of viruses, where the source of infection is unknown, remains a concern, necessitating strong public health responses. Iran's MOHME has enacted measures to strengthen hospital readiness, ensuring that healthcare facilities are equipped to manage outbreaks and provide appropriate care. The Center for Communicable Diseases Control, a department within the Ministry of Health and Medical Education in Tehran, Iran, is at the forefront of these efforts, working tirelessly to monitor, prevent, and control the spread of infectious agents across the nation. Their work, combined with improved sanitation and active surveillance, has been instrumental in the progress observed.

Oral Health in Iran: Addressing Neglected Needs

While the focus often lies on life-threatening systemic diseases, oral health also represents a significant public health challenge in Iran. The findings address the challenging changes in oral diseases and difficulties in responding to the urgent oral health needs in Iran. The burden of oral diseases should be considered as a priority in Iran, given their widespread prevalence and impact on overall well-being. A critical need also exists to pay more attention to the oral health policies and principles of prevention. This includes promoting oral hygiene practices, ensuring access to dental care, and integrating oral health into broader public health initiatives. Neglecting oral health can lead to systemic health issues, making it an integral part of a holistic approach to managing diseases in Iran.

Public Health Achievements: Milestones in Maternal and Child Health

Iran has achieved remarkable success in certain areas of public health, particularly in maternal and child health. Notably, Iran is one of the few countries in the world that reached targets of the Millennium Development Goal (MDG) number 5 on 2008, seven years ahead of the planned time. This goal focused on improving maternal health, demonstrating Iran's commitment and effectiveness in reducing maternal mortality rates. Furthermore, the cause of neonatal mortality has changed in the past two decades. While the share of infectious diseases has been decreasing, the importance of prematurity and congenital disorders was increasingly recognized. This shift indicates improved control over infectious causes of infant mortality and a greater capacity to identify and manage other critical factors affecting newborn survival. These achievements reflect a strong public health infrastructure and dedicated efforts to protect the most vulnerable populations.

The Role of National Surveillance and Collaboration in Disease Control

The continuous improvement in public health standards and the establishment of robust national surveillance systems have been pivotal in transforming the health landscape and controlling the spread of diseases in Iran. These systems allow for the timely detection, reporting, and response to disease outbreaks, enabling health authorities to implement targeted interventions. The close collaboration between the Ministry of Health and the Veterinary Organization is a cornerstone of this strategy, especially for zoonotic diseases where animals are primary reservoirs. Organizations like the Department of Epidemiology and Biostatistics, Research Centre for Emerging and Re-emerging Infectious Diseases at the Pasteur Institute of Iran, play a crucial role in conducting research and providing laboratory support for disease surveillance. Despite the progress, the need for improved sanitation, active surveillance, comprehensive infection control strategies, and monitoring appropriate use of antibiotics remains indispensable to further alleviate the burden of diseases in Iran.

Future Outlook: Sustaining Progress in Iran's Health Sector

The health sector in Iran faces a dual challenge: continuing to suppress infectious diseases while simultaneously tackling the rising tide of non-communicable diseases. The nation's journey from a high burden of infectious and diarrheal diseases to a landscape dominated by conditions like cardiovascular disease highlights both its past successes and future imperatives. Sustaining the progress achieved requires ongoing investment in public health infrastructure, research, and human resources. The emphasis on prevention, early detection, and effective management of NCDs will be crucial. Furthermore, maintaining vigilance against re-emerging infectious threats and strengthening the "One Health" approach for zoonotic diseases will ensure a comprehensive health security framework. The Iranian people have suffered much from various health challenges, but the advancements made demonstrate a strong foundation for continued improvement in health outcomes.

For individuals traveling to or residing in Iran, understanding the prevalent diseases and taking appropriate precautions is essential for personal health and safety. As highlighted, vaccination for Hepatitis A and B is recommended by the CDC for those visiting the Middle East, given their commonality among diseases in Iran. Practicing good food and water hygiene is also paramount to prevent food or waterborne illnesses. Awareness of zoonotic disease risks, especially in rural areas, and avoiding contact with potentially infected animals can reduce exposure. While the incidence of many infectious diseases has decreased, basic precautions like handwashing and being aware of local health advisories remain important. The Iranian Ministry of Health and Medical Education is committed to public health, and their measures to strengthen hospital readiness underscore their dedication to providing care. By staying informed and proactive, individuals can significantly mitigate health risks and enjoy a safer experience in Iran.

The evolving health landscape in Iran presents both challenges and opportunities. The shift from infectious to non-communicable diseases reflects a successful public health transition, yet it also underscores the need for new strategies to combat chronic conditions.
