A poor understanding of Ebola Virus Disease (EVD) among Health Care Professionals (HCPs) may put our lives at risk. We aimed to assess the awareness, knowledge, attitudes, perceptions, beliefs of HCPs towards Ebola at Gondar University Hospital (GUH) in Northwest Ethiopia. We conducted a hospital based, cross-sectional survey among 245 randomly selected HCPs working at GUH from August-October, 2015. A validated, self-administered questionnaire was used to collect the data. We calculated descriptive statistics with P<0.05 being statistically significant. Of the 245 participants, 211 (86.1%) completed the study. The majority had heard about EVD and used news media (62%) as a source of information. Still, many were afraid of getting EVD (56.4%; P=0.001). A significant number of HCPs thought EVD can cause paralysis like polio (45%) and can be treated with antibiotics (28.4%). In addition, 46.4% of the HCPs felt anger or fear towards Ebola infected patients (P=0.006). We identified poor knowledge and negative incorrect beliefs among doctors and allied health professionals. There is a need for intensive training for all HCPs reduce EVD risk.
Paralytic poliomyelitis is a constantly rising problem in the developing world. It may take an insiduous endemic "infantile paralysis" behaviour exacting a high toll in the first few years of life, as in Ghana or Burma but on the other hand it may take the form of sudden extensive outbreaks of paralytic disease as in Argentina, Mexico or Malaysia. The developed world has controlled the disease by effectively immunizing a very high proportion of their populations, but those who have not been vaccinated are at risk even in countries with very high coverage, as has been noted in the Netherlands, Sweden, United States of America, etc. There is no reason to have a crippled paralytic child (or adult). Both the live and killed vaccines have been repeatedly shown to be safe and effective. The minute risk incidental to vaccination is more than one hundredfold smaller than the risk from the disease, not only in the developing world but in the developed world as well. Therefore, the question of which vaccine to use is of far less relevance than of how to increase effective coverage with any available vaccine. This does not mean that vaccine control should be relaxed. A health respect should be maintained for the polioviruses used as vaccine sources and great care must be exercised by those undertaking the manufacture or the administration of vaccine.
In 1988, the World Health Assembly resolved to eradicate poliomyelitis globally by 2000. A plan of action for polio eradication in the Western Pacific Region (WPR) by 1995 was adopted in 1990. The plan was based on routine and supplemental vaccination activities with oral poliovirus vaccine (OPV) and acute flaccid paralysis (AFP) surveillance in the eight countries where polio was endemic (Cambodia, China, Laos, Malaysia, Mongolia, Papua New Guinea, Philippines, and Vietnam). Regionwide, the number of reported polio cases decreased from approximately 6000 in 1990 to zero in 1998. This report describes the extensive efforts to eliminate the last chains of poliovirus transmission in the Mekong River area.

In 1988, the World Health Assembly adopted the goal of global poliomyelitis eradication by 2000, which was endorsed in each of the six regions of the World Health Organization (WHO). In the Western Pacific Region (WPR), where the last known case of polio associated with isolation of wild poliovirus occurred in March 1997, the reported number of cases decreased from 5963 in 1990 to 197 in 1996. This report documents progress toward polio eradication in WPR from January 1, 1996, through September 27, 1997, in countries where polio is endemic (Cambodia, China, Laos, Papua New Guinea, Philippines, and Vietnam) or recently was endemic (Malaysia and Mongolia) and describes the routine and supplemental vaccination activities necessary to interrupt wild poliovirus transmission in the region.

The last confirmed case of poliomyelitis in West Malaysia was in 1986', and over the past few years, we have condescendingly associated polio with other developing countries. Recently, 2 children with acute flaccid paralysis (AFP) were confirmed as cases of poliomyelitis due to a wild strain of the virus. This implies a failure of the immunisation programme to contain the spread of the wild virus (Hall). However, if we look at the WHO standard case definition of polio virus infection (appendix 1) it is possible that we could have missed a few cases over the last 6 years. At this juncture a brief clinical summary of the 2 cases and a discussion of the differential diagnosis may be useful. (Copied from article).
Poliomyelitis in Malaysia has not been reported since 1986. We report two cases of poliomyelitis in non-immunized children whose parents, though relatively educated, opted not to vaccinate their children for socio-cultural reasons. This recent trend may interfere with our attempts to eradicate poliomyelitis globally by the year 2000. The clinical features, pathophysiology and differential diagnosis are discussed.

Immunization is the process of making individuals immune. Childhood immunization is a common process for various aliments, but adult immunization in the Indian scenario is obscure. Officially, India has been declared polio-free, which is an achievement despite cultural, political, economic, geographic, and so many other factors. The changing demographics of adult, geriatric population and growing cost of health-care maintenance are a concern in developing countries like India. Thus, promoting healthy lifestyle needs prevention, early detection, and management of various diseases and disorders. Certainly, prevention in adults is yet to be tapped completely, so that goal of 100% prevention can be achieved. Various fraternities of medical association have come up with guidelines for adult immunization schedules in India. The present paper reviews infectious diseases such as anthrax, chikungunya, cholera, dengue, influenza, and malaria in this section of the review. We humbly request all health-care professionals and educators to educate the mass for adult immunization. So that, cost involved for treatment and workforce for the management of diseases can be better utilized in some other needed areas.
Introduction: Poliomyelitis is an incapacitating and highly infectious disease which effect mostly young children. It is caused by one of the three serotypes of polioviruses (PV) and transmitted through faecal-oral route hence making the disease quite pertinent to the lower and middle class society or under-immunized population. This surveillance is one of the strategy included by WHO in the “Eradication, Integration and Certification: The Endgame Strategy 2019-2023” as a supplement to AFP surveillance by which it could be more sensitive to detect low circulation of WPV and circulating vaccine derived poliovirus (cVDPV). Methods: Routine collection and testing of representative environmental surveillance are carried out in the National Polio Laboratory. The specimens are collected from designated locations draining target populations at increased risk of poliovirus transmission using the grab method once a month and processed according to WHO standard protocol. Polioviruses were identified by real time reverse transcriptase polymerase chain reaction (rRT-PCR) for intratypic differentiation (ITD) and vaccine derived poliovirus (VDPV) whereas non-polio enteroviruses (NPEVs) were identified by PCR and sequencing. Results: From 2012 to 2019, results showed various isolation of PVs and NPEVs. A total of 12 sewage disposal plants located in urban highly populated areas in Kuala Lumpur (3), Selangor (5), Sabah (3 ) and Negeri Sembilan (1) were investigated. A total of 22 Sabin-like PVs were isolated consisting of 3 PV1, 8 PV2 and 11 PV3 thus indicated that in Malaysia even though PVs were existed in environment, but all of them were Sabin-Like viruses and no evidence of imported WPV or VDPV in the sampling sites. Conclusion: Even though Malaysia has been declared as WPV free country in 2000, Environmental Surveillance is very important and crucial in detecting the introduction and silent circulation of WPV and cVDPV before the virus reaches the community.
Pakistan accounts for 85.2% of the total polio cases reported worldwide. Healthcare workers (HCWs) are an integral part of immunization campaigns and source of education for the general public. This study aimed to assess the knowledge and attitudes towards polio vaccination among HCWs providing immunisation and education to general public in Quetta and Peshawar divisions of Pakistan.
Despite the efforts of national and international organizations, polio has not been eradicated from Pakistan. The prevalence of polio in Pakistan is exceptional in global context. Quetta and Peshawar divisions are amongst the most affected regions hit by polio in Pakistan. This study was carried out to assess the knowledge, attitudes and perceptions towards polio immunization among residents of Quetta and Peshawar divisions in Pakistan.
Pakistan is one of the two countries where polio remains endemic. Among multiple reasons of polio prevalence, false religious beliefs are accounted as major barriers towards polio immunization in Pakistan. Within this context, religious scholars are now engaged in polio immunization campaigns to dismantle the myths and battle the resurgence of polio in Pakistan. The objective of this study was to assess knowledge, attitudes and perceived barriers of Muslim scholars towards polio immunization in Pakistan. A descriptive, cross-sectional survey of Muslim scholars was conducted in Quetta and Peshawar divisions of Pakistan. From October to December 2015, a convenience sample of 770 Muslim scholars was recruited from the local mosques and religious institutions to participate in this study. Knowledge, attitudes, and perceived barriers were assessed by using self-administered, anonymous and pretested questionnaire. Descriptive and regression analyses were used to express the results with p
A qualitative study design was adapted to explore the challenges faced by health workers (HWs) during the polio health campaign. In addition, HWs' opinions about the factors causing parents to refuse oral polio vaccination (OPV) were also explored. Four focus group discussions (FGDs) were held (from 1st January 2015-31st March 2015) with the HWs who participated in the OPV campaigns in the polio red zones of Khyber Pakhtoon Khawa (KPK) province of Pakistan, namely Kohat (FG 1), Domel and Bannu (FG 2), Hangoo (FG 3), and Peshawar (FG 4). A total of N=42 HWs (10-11 in each FG) agreed to participate in this study. Overall, HWs disclosed that public attitude and harsh behaviour towards the HWs and security threats are the two main challenges they face. Common issues hindering parents' willingness to vaccinate their children against OPV are: OPV is seen as haram and not permitted in Islam, it is said to contain the blood of pigs (Khinzir) and monkeys, and parents are afraid that it is done to induce sterility among their children. HWs also shared that parents have a strong belief in the conspiracies that are associated with OPV, i.e. the USA and CIA, are spying on us and our government is helping them to achieve their agenda. Furthermore, HWs revealed that frequent visits may further strengthen parents' perceptions and make them more resistant to OPV. The common side effects of OPV reported by parents were mainly gastro-intestinal problems and in some cases mild to moderate fever with some respiratory symptoms. There is a great need to improve the logistics and facilities for HWs assisting in vaccination programmes. Furthermore, it is necessary to improve education, so people understand the basic concept of revaccination and booster doses, thereby assisting in creating a basic understanding of vaccinations, which may trigger changes in attitudes and make people believe in the benefits of OPV rather than following the conspiracies that lead them to refuse it.
Poliovirus kept on the cut surfaces of fully ripe papaya cubes placed in an ice box showed a sharp and significant reduction in the recovery of infectious virus about 15 minutes after exposure. Thereafter, a very gradual decrease ensued and infectious residual virus was detected up to the end of the 6-hour exposure period. Papaya cubes washed or kept overnight before virus inoculation, and from less ripe fruits produced a similar survival pattern. A very small proportion of the inoculum was recovered from the mashed content of the inoculated papaya cubes thus suggesting that most of the non-recovered virus particles were inactivated. The results suggest that the importance of poliovirus-contaminated cut papayas as a transmission vehicle for the virus is greatly reduced by the rapid decline in the infectivity of a large proportion of the virus soon after contamination. Nevertheless, the potential to transmit remains as a small residual pool of infectious poliovirus is able to survive for a relatively long period.
We present a unique case of tibial post fracture of a posterior-stabilised total knee arthroplasty (PS-TKA) using highly crosslinked polyethylene (HXLPE) in the unafflicted limb of a patient who had poliomyelitis. The tibial post is an upright structure perpendicular to the PE insert articular surface which articulates with the cam of the femoral component to prevent excessive posterior translation of the tibia. We explore the choice of PS polyethylene (PE) inserts in patients with neuromuscular disorders (NMD). A 74-year old gentleman presented with recurrent knee pain seven years after the index PS-TKA with HXLPE. The TKA was performed on the unafflicted left limb (contralateral to the weak side affected by poliomyelitis). The posterior drawer test was positive. During the single-stage revision surgery, the HXLPE tibial post was noted to be broken. The liner was replaced with a thicker non-HXLPE. The patient achieved an excellent outcome at one-year post-surgery. This is the first report of HXLPE tibial post fracture in the unaffected knee of a patient with NMD affecting the lower limb. The HXLPE's reduced resistance to fatigue crack propagation might not be suitable in PS-TKA where there might be focal stress points on the tibial post, which was amplified in this case as it was the limb that the patient most depended on. When managing end-stage osteoarthritis with TKA in the unafflicted knee of a patient with NMD causing lower limb weakness, the selection of polyethylene material in PS-TKA may need more consideration than previously thought.
