Taking any form of sample from a deceased patient has inherent life-threatening risks for response workers (Manguvo and Mafuvadze 2015). Issues arise during the removal of bodies, filling body bags, safe burials, mass burials and even cremation. What these issues give rise to is not just the proposal of an unwelcomed burial or an invasive autopsy, it relates to the deceased and how the deceased are managed in different cultures (Manguvo and Mafuvadze 2015; Sajid 2016a; Sajid 2016b; Al-Saif et al. 2016; Madadin et al. 2014; Marshall and Smith 2015). This affects the capacity to undertake autopsy, sampling, or safe burials.
Virtual autopsy (virtopsy)
There is a deep chasm between what scientists want to undertake and how communities perceive it from traditional, religious, or spiritual points of view. Therefore, we need to engage in the kind of research, investigation and dialogue that will lead us to a mutually acceptable solution. One of these could be virtopsy. This is an innovative technique for overcoming the concerns, needs and requirements of one side and the scientific aims of the other. It can serve as a proper entry point to negotiations around the examination of the deceased.
One of the unique advantages to virtopsy is using hand-held devices [e.g. portable ultrasound (US)] for non-invasive or minimally invasive imaging-guided biopsy. In poor or remote regions, these devices could serve as an alternative when better resolution imaging scans are unavailable [e.g. magnetic resonance imaging (MRI) or computed tomography (CT)]. Portable ultrasound devices open the possibility to obtain tissue samples for histological and molecular diagnosis in areas that have experienced outbreaks of communicable diseases or regions where the aetiology is unknown.
For an outbreak situation in remote regions where a top-level high-security laboratory is unavailable, very few interventions are possible without basic personal protection equipment. It is likely that portable ultrasound-guided Tru-Cut needle biopsy can be the only option. The ultrasound cannot differentiate communicable causes from others. It only guides the needle so that major organs or fluid accumulations can be punctured. At night, ultrasound can also be used in the darkness of a medical tent when lighting is not available. In brief, such use of portable ultrasound-guided biopsy might have been very useful in these outbreaks (O’Sullivan et al. 2017). In addition, ultrasound-guided needle biopsy could have been highly effective in quickly identifying the cause of the outbreak (O’Sullivan et al. 2017). This approach may have reduced the number of Ebola cases worldwide. Moreover, this could have potentially enabled an earlier diagnosis linking Zika virus to microcephaly recently in Northeast Brazil (O’Sullivan et al. 2017). If the diagnosis was made earlier, additional cases may have been prevented. Earlier diagnosis may make it possible to devise protection policies that greatly reduce the number of individuals who are affected by Ebola or Zika virus.
However, these portable technologies are still not as reliable as conventional virtopsy technologies (e.g. MRI or CT). In general, ultrasound imaging cannot match these technologies in terms of data quality, detail and resolution. Nevertheless, these hand-held devices cost far less and may be the best alternative for individuals with metallic heart valves, pacemakers, implanted cardiac defibrillators, or high body mass index (preventing them from being able to physically fit in a medical imaging scanner)—currently unsuitable for conventional virtopsy. Diagnosis with these portable devices can potentially prevent contamination and spread of communicable diseases in such regions, as well as increasing public acceptance of usage.
Establishing virtopsy as a feasible alternative to conventional autopsy not only increases acceptance among certain populations, it can also lead to identifying more pathogens and increasing scientific discoveries or advancements in the years ahead. A recent study aimed at determining the diagnostic accuracy of post-mortem MRI, CT and CT-guided biopsy (with conventional autopsy used as reference standard) was based on 100 consecutive adult patients who died in a hospital setting (Wagensveld et al. 2018). The authors found that combining MRI with biopsies had high sensitivity and specificity for detecting acute and chronic myocardial ischaemia (Wagensveld et al. 2018).
Non-invasive or minimally invasive virtopsy response work is very straightforward but extremely significant. Many countries can train their response and military personnel on how to perform a safe virtopsy procedure in an outbreak situation. It is also possible to overcome any education and training limitations by investing in human capital and local capacities who are able to carry out a proper response. Developed regions in Africa have the capacity to facilitate and cater for virtopsies using MRI or CT machines. An alternative, non-invasive technique (e.g. virtopsy) is ideal for developed Muslim countries such as Saudi Arabia, Qatar, Brunei, United Arab Emirates, Oman, Kuwait, Bahrain and Malaysia, among others. The world’s Muslim population is expected to rapidly grow from 23% (ca. 1.6 billion) in 2010 to 30% (nearly 2.8 billion) in 2050. Muslims are expected to grow twice as fast as the overall global population (Pew Research Center 2015). Europe’s Muslim population is projected to grow by 63%, increasing from 5.8% (43 million) in 2010 to 10.2% (71 million) in 2050 (Pew Research Center 2015).
The goal should be to maintain autopsy, but with the inclusion of this updated, innovative methodology, as a core science in understanding diseases. Response teams should listen, understand and adapt their scientific vocabulary, using appropriate descriptions and examples, before engaging with African communities and then introducing an innovative alternative such as virtopsy.
Community engagement
In terms of the scientific field, there is a misinterpretation concerning traditional, religious or spiritual beliefs and there has previously been unwillingness to adapt to them (Manguvo and Mafuvadze 2015; Sajid 2016a), and this leads to a breakdown in trust. There is the need for a proper understanding of indigenous community traditions, customs or belief systems. Response groups may find that engaging with these African communities in an appropriate respectful manner results in a compromise that works effectively. This could prevent the blaming of religion or belief systems as the cause of spreading diseases. The focus should be maintained on trying to gain a better understanding of how the international medical/scientific world can engage with these communities more successfully (Sajid 2016a; Al-Saif et al. 2016; Madadin et al. 2014; Marshall and Smith 2015). Therefore, the first step is to find ways in which non-native healthcare practitioners can perform the necessary scientific work (e.g. virtopsy), whilst simultaneously being sensitive to the local importance of traditional, religious or spiritual beliefs (Sajid 2015).
The second step taken to avoid conflict is engaging with leaders or influential individuals in these villages (Manguvo and Mafuvadze 2015). These leaders or influential individuals sometimes include chiefs, village headmen, church pastors, mosque imams, religious leaders, spiritual leaders and even healers. The term healer can also relate to diviners, traditional healers, spiritual healers, traditional doctors, witch doctors, sorcerers or medicine men/women, among others. These leaders or influential individuals usually hold extremely influential power within these communities (Manguvo and Mafuvadze 2015; Sajid 2016a; Sajid 2016b; Marshall and Smith 2015).
In the past, in some remote regions of Africa, if a person was suspected by a healer to have carried a disease into their village, the consequences led to violent ritual executions of that person by the villagers. Rumours or horror stories of these tragic events can build up reluctance among non-native aid workers who would be willing to volunteer and travel to these remote regions of Africa. The Ebola outbreak of 2014 had a very slow number of volunteers in the early stages of the outbreak (2–3 months delay) (Gates 2015), which is a factor that also contributed to the undue duration and length of the outbreak. On the other hand, non-native charity/aid workers need to have had sufficient professional background checking for suitability and should receive training in reducing their own ability to transmit disease to the locals they are caring for, as well as those in their country of origin upon their return. A number of cases in the media discussed health care workers returning to their countries with Ebola (e.g. in 2014, one of the cases involved a nurse from Scotland that volunteered in Sierra Leone, who then fell ill on return to Glasgow) (Gulland 2016).
For Christians/Muslims, their imams and pastors may play a major role in reaching out to many people. In relation to Christianity as a religion in Africa, there are issues surrounding ‘devil worship’ which is a thorny issue in the faith. There is a belief that body parts are removed and used for sinister motives associated with Satanism. The majority of Muslims (in Africa and elsewhere) are opposed to invasive autopsy; this is due to religious reasons, burial delays or abhorrence of what they consider the mutilation of the dead. Universal objection of conventional autopsy has led to the search for verbal autopsy and non-invasive or minimally invasive alternatives (e.g. virtopsy); needle biopsy can be found to be less invasive, whereas imaging is found to be a non-invasive substitute of autopsy.
Islamic advances (such as catgut sutures in surgery, informed consent for surgery, prophetic medicine, the first ever university and teaching hospitals as we know them today) have evidently helped science, for instance, from medieval Islamic times to modern era science. Abu’l Qasim al-Zahrawi (born in Spain 936 AD) is considered the greatest medieval surgeon to have appeared from the Islamic World; he has been described as the father of surgery and authored the Kitab at-Tasrif (a 30-volume Arabic encyclopaedia on medicine and surgery that included pictures and details of many new surgical instruments).
There is a common misconception that Islam has only recently surfaced as a major religion or that the number of Muslims has only increased recently in Europe following arrival of migrants and refugees. Islam has been a part of Europe for a long time (Shah 2011; Chaudhary 2017; Redžić 2005). Jean de Joinville (chronicler of Medieval France and the Crusades) reported that he was rescued by a Saracen doctor in 1250—the Crusaders testified that they depended upon Arab doctors on frequent occasions. Avicenna’s ‘The Canon of Medicine’ (1025) was translated and disseminated worldwide—he noted the contagious nature of numerous communicable diseases and attributed these to ‘traces’ left in the air by a sick person. A united approach using inspirational techniques from the past and findings in the present would lead to beneficial outcomes in the future.
In the current climate, it would be more credible and appropriate if the lead on this comes from physicians/scientists (providing an evidence-based approach) working jointly in cooperation with communities (including Muslims) to champion this cause and increase worldwide education of alternative choices to the conventional autopsy genuinely now available, with the potential for this to be available at no extra cost to them (Lancashire County Council 2018; Sajid 2016a; Sajid 2016b; Sayligil and Ozden 2014; Speech by HRH Prince Charles at Oxford centre for Islamic studies 1993; Sterns 2015; Sajid and Sajid 2007; Madadin et al. 2014; Saad Foundation n.d.). This post-mortem issue can also be negotiated by members of the academic or theological fields willing to deal with those representing the health, medical or scientific fields. A similar strategy proved successful for polio programs; these involved deep negotiations to overcome resistance to vaccinations, based on them being ‘haram’ (an act that is forbidden by Allah) as opposed to being ‘halal’ (permissible).
