An Emerging Health Crisis in Turkey and Syria after the Earthquake Disaster on 6 February 2023: Risk Factors, Prevention and Management of Infectious Diseases.

On 6 February 2023, Turkey and Syria were hit by two major earthquakes that caused extremely heavy structural damage to buildings and infrastructure in one of the most densely populated areas of Anatolia. The authors visited the devastated area shortly after the earthquakes in the frame of search and rescue and scientific missions in order to check whether the newly formed conditions have the potential to further affect public health. Based on the collected disaster-related field data, it is revealed that risk factors associated with and favoring emergence of infectious diseases are present in the affected residential areas from the first hours of the emergency state. The coexistence and synergy of many collapsed health facilities, cold winter conditions, destruction of lifeline infrastructures, overcrowding in emergency shelters, poor sanitation and adverse socio-economic conditions along with evolving crises and disasters (conflicts, pandemic and epidemics) may further aggravate the already fragile public health situation and cause considerable delays in the recovery process. Efficient disease surveillance at local and regional levels is a crucial requirement for early warning and protection against emerging infectious diseases in the earthquake-affected areas among other proposed measures for prevention and management of infectious diseases.

The Impact of Earthquakes on Public Health: A Narrative Review of Infectious Diseases in the Post-Disaster Period Aiming to Disaster Risk Reduction.

Earthquakes are among the most impressive natural phenomena with very high potential to set off a chain of effects that significantly affects public health through casualties and injuries. Related disasters are attributed not only to the strong ground motion and coseismic phenomena but also to secondary effects, comprising mainly landslides and tsunamis, among others. All these can create harsh conditions favorable for the emergence of infectious diseases that are capable of causing additional human and economic losses and disruption of the emergency and recovery process. The present study comprises an extensive narrative review of the existing literature on the earthquake-triggered infectious diseases recorded worldwide, along with their symptoms, causative pathogens, associated risk factors, most vulnerable population groups, and prevention strategies. Respiratory, gastrointestinal, and vector-borne diseases, as well as wound and skin infections, are mainly recorded among the earthquake-affected population. Measures for effectively preventing earthquake-triggered infectious diseases are also proposed. One of the widely proposed measures is the establishment of a proper disease surveillance system in order to immediately and effectively identify the pre- and post-disaster occurrence of infectious diseases. This approach significantly contributes to disease trends monitoring, validation of early warning, and support of the emergency response and recovery actions.

Infectious Diseases Associated with Hydrometeorological Hazards in Europe: Disaster Risk Reduction in the Context of the Climate Crisis and the Ongoing COVID-19 Pandemic.

Hydrometeorological hazards comprise a wide range of events, mainly floods, storms, droughts, and temperature extremes. Floods account for the majority of the related disasters in both developed and developing countries. Flooding alters the natural balance of the environment and frequently establish a favorable habitat for pathogens and vectors to thrive. Diseases caused by pathogens that require vehicle transmission from host to host (waterborne) or a host/vector as part of their life cycle (vector-borne) are those most likely to be affected by flooding. Considering the most notable recent destructive floods events of July 2021 that affected several Central Europe countries, we conducted a systematic literature review in order to identify documented sporadic cases and outbreaks of infectious diseases in humans in Europe, where hydrometeorological hazards, mainly floods, were thought to have been involved. The occurrence of water-, rodent-, and vector-borne diseases in several European countries is highlighted, as flooding and the harsh post-flood conditions favor their emergence and transmission. In this context, strategies for prevention and management of infectious disease outbreaks in flood-prone and flood-affected areas are also proposed and comprise pre- and post-flood prevention measures, pre- and post-outbreak prevention measures, as well as mitigation actions when an infectious disease outbreak finally occurs. Emphasis is also placed on the collision of floods, flood-related infectious disease outbreaks, and the evolving COVID-19 pandemic, which may result in unprecedented multi-hazard conditions and requires a multi-hazard approach for the effective disaster management and risk reduction.

Respiratory Infections Following Earthquake-Induced Tsunamis: Transmission Risk Factors and Lessons Learned for Disaster Risk Management.

Earthquake-induced tsunamis have the potential to cause extensive damage to natural and built environments and are often associated with fatalities, injuries, and infectious disease outbreaks. This review aims to examine the occurrence of respiratory infections (RIs) and to elucidate the risk factors of RI transmission following tsunamis which were induced by earthquakes in the last 20 years. Forty-seven articles were included in this review and referred to the RIs emergence following the 2004 Sumatra-Andaman, the 2009 Samoa, and the 2011 Japan earthquakes. Polymicrobial RIs were commonly detected among near-drowned tsunami survivors. Influenza outbreaks were commonly detected during the influenza transmission period. Overcrowded conditions in evacuation centers contributed to increased acute RI incidence rate, measles transmission, and tuberculosis detection. Destruction of health care infrastructures, overcrowded evacuation shelters, exposure to high pathogen densities, aggravating weather conditions, regional disease endemicity, and low vaccination coverage were the major triggering factors of RI occurrence in post-tsunami disaster settings. Knowledge of risk factors underlying RIs emergence following earthquake-induced tsunami can contribute to the implementation of appropriate disaster prevention and preparedness plans characterized by sufficient environmental planning, resistant infrastructures, resilient health care facilities, and well-established evacuation centers. Global and local disease surveillance is a key prerequisite for early warning and protection against RIs' emergence and transmission in tsunami-prone areas.

Geological and hydrometeorological hazards and related disasters amid COVID-19 pandemic in Greece: Post-disaster trends and factors affecting the COVID-19 evolution in affected areas.

Since the first confirmed COVID-19 case in December 2019 the pandemic has severely affected humanity in various ways on all sectors of the everyday life. Natural hazards and related disasters did not stop for the novel virus. The parallel evolution of disasters and the pandemic have high potential for producing compound emergencies characterized by new unprecedented challenges. Greece was no exception. It was struck by disasters induced by geological and hydrometeorological hazards amid the pandemic. The most destructive events in terms of human and economic losses were the Mw = 5.7 Epirus and Mw = 6.9 Samos earthquakes on March 21 and October 30 respectively, the Evia flood on August 9 and the Ianos medicane in mid-September 2020. We studied the daily recorded laboratory confirmed COVID-19 cases in the disaster-affected areas in selected pre- and post- disaster periods. Increase of the reported COVID-19 cases in the post-disaster period has been detected only after the Ianos medicane in affected areas. No change in cases was observed after the studied earthquakes and flood. We examined various factors related to the evolving pandemic, the studied disasters and their management plan that may have contributed to the post-disaster evolution of cases. It is shown that the preexisting viral load and the infection rate in the affected areas, the intensity of the disaster effects and the measures adopted for the effective disaster management of the compound emergencies have the potential to affect the post-disaster evolution of the pandemic in the disaster affected areas.
