So how at all is Ebola transmitted? Series Two

Follow me on Twitter

Transmission of Ebola Virus.

There has been so much media hype and scare about the transmission of the Ebola virus. Ebola is not airborne and so containment is very possible. The situation is not as bleak as the hype puts it.

The first contact leading to an outbreak is believed to be zoonotic – from an infected animal (mostly bats) to human. This is tentative though as researchers have not yet been able to pin down on this hypothesis. It thus remains hypothetical for now.  

Following a successful zoonotic transmission, the remainder of the epidemic remains human to human though fresh zoonotic transmission is still possible. Once EVD is established, the possible routes of transmission are;
  • ·         direct contact with the blood or secretions of an infected person
  • ·         exposure to objects (such as needles) that have been contaminated with infected secretions.
Friends and family are the nearest at high risk of contracting the virus in the home setting as they are closer to the patient. The patient’s contacts in bus stations and public gatherings are also at risk but depend on the stage of the progression of the virus in the patient’s body. It takes approximately three weeks within which one can break down with EVD. You are less risky to the public if you have the virus and do not bleed or secrete body secretions or have family and friends come into contact with your body fluids. 

Health workers need to up their emergency response protocols. Adequate protective clothing are essential to gaping the spread of Ebola in health care workers.

Avoid body contact with travelers in the outbreak belt.

Stay tuned.

Introduction to The Ebola Virus Disease. Series One

Follow me on Twitter here.

The Ebola Virus Disease (EVD) or Ebola Haemorrhagic Fever (EHF) is not a new disease in sub-Sahara Africa, but it is the latest viral threat – without known and readily available vaccine(s) or cure – on public health in West Africa. The first cases of Ebola simultaneously broke out in the Democratic Republic of Congo and Sudan. The former’s outbreak occurred along the Ebola River hence its name – Ebola Virus.

The Ebola virus belongs to a family of viruses known as the Filoviradae. This family of viruses has three sub-families or genera which comprise a), b), and c). There are five species of the Ebolavirus as denoted by I, II, III, IV and V.
1)      Filoviradae
a)      Marburgvirus
b)      Cuevavirus
c)       Ebolavirus
                                                              I.      Bundibugyo ebolavirus (BDBV)
                                                            II.      Zaire ebolavirus (EBOV)
                                                          III.      Reston ebolavirus (RESTV)
                                                          IV.      Sudan ebolavirus (SUDV)
                                                            V.      Taï Forest ebolavirus (TAFV) formerly Cote d’Ivoire ebolavirus

Since its first outbreak in 1976, all five save Reston ebolavirus has been implicated in causing human disease. And, the first and only case in West Africa was reported in Cote d’Ivoire in 1994. The current species of the West African bane has been identified by the Pasteur Institute, Lyon, France through polymerase chain reaction and viral sequencing as the Zaire ebolavirus. EVD has registered a case fatality rate of up to ninety percent in the past. What does this mean for the lay person? It means that, out of ten confirmed cases of the disease, nine people have died and only one person survived. That is the reason why the World Health Organization and nation governments are very concerned about the virus leaping borders.

West Africa has one of the most porous borders in the world hence the need for you and me to take personal and collective responsibility in bringing this disease under control. 

The natural reservoir host of ebolaviruses remains unknown. However, on the basis of available evidence and the nature of similar viruses, researchers believe that the virus is zoonotic (animal-borne) with bats being the most likely reservoir. Four of the five subtypes occur in an animal host native to Africa. [CDC, 2014]

The World Health Organization Regional Office in Africa, 2014, technically defines a suspected case of Ebola as;
“Illness with onset of fever and no response to treatment for usual causes of fever in the area, and at least one of the following signs: bloody diarrhoea, bleeding from gums, bleeding into skin (purpura), bleeding into eyes and urine.” 
And a confirmed case as;
“A suspected case with laboratory confirmation (positive IgM antibody, positive PCR or viral isolation).”

Financing Health Education in Ghana: Policy Alternatives



Background and Arguments
When the debate for scrapping off teacher trainee allowances was raging, it was voraciously expected that same will shift to the health sector. Lo, same debate has been commissioned with some people calling for the allowances of health trainees to be equally scrapped off.
The proponents of the scrapping off of the allowances base their arguments principally on equity across board – education and health sectors. They also think that there is no accountability in the disbursement of allowances and that salaries and wages account for 90% of the health sector’s budget while the remaining 10% goes into service delivery.
Be it as it may, one must not necessarily call for the killing of the gander simply because the geese have been killed. That notion simply does not click. While I do not undermine the teaching profession, I think that the condition that exists in their sector is not the same as it is in the health sector. The ministry of education and the ministry of health are not operating on the same budget; therefore if the education ministry thinks that its budget cannot support the payment of allowances to trainee teachers’, it does not necessarily imply that the health ministry should do same. The health of a nation’s citizens is directly linked to its productivity and development and we must not lose sight of that fundamental fact to behave in a way that will shift the balance of the forces holding the health of the nation in equilibrium.
Trainee allowances were introduced to attract students to the health professions because people in past times considered nursing as a ‘dirty’ job. It was also introduced to attract human resource to bridge the widened gap between the population ratios of nurses and for that matter other health professionals and the population at large. Suffice it. Are we saying that we have been able to achieve these crucial indices? Or are we saying that we have been able to meet the health related Millennium Development Goals? However you answer the rhetoric, few things needs consideration.
If 90% of the health sector budget goes to the payments of salaries and wages, 90% of that goes to the payment of salaries of doctors and directors and not to trainees. That is the inequity policy makers should be addressing and not scrapping off of the meager allowances paid to health trainees. If those in policy are arguing that there is no accountability in the payment of these allowances, it is simply an administrative fiasco on their part and I honestly think they should not stick their heads to discuss this issue publicly. They must be held accountable for that lapse because it is the taxpayer who suffers when such heinous flaws are committed.
There is every justification why health trainees like any of their colleagues in the other sectors should enjoy their allowances. In 2006, the average fee per annum in health training institutions was about GHC 350 and GHC 450, today, it is well over GHC 1500. Many trainees rely on their allowances which are raked back by government in the form of fees. What is the allowance here then when all you receive is paid back to government through fees?  Another dimension of inequity policy makers are in oblivion of is the fact that scrapping off of the allowances will mean that the poor cannot go to school. Only the rich who can afford college education should be in school. This is inequity better defined.
The proponents of this chauvinist policy further submit that as a result of the allowance, the right calibers of people are not admitted into the health system. To this end I agree conditionally. The right caliber of people can be admitted into the health system if the processes of admission into health training institutions are purged of nepotism and undue pressure on principals and directors to admit their cronies. Attending an interview before you gain admission into a health training institution was meant to filter the right caliber of health trainees into the health system but that effort has been completely defeated due to pressure from politicians and policy makers to by all means gain admission for their cronies and sympathizers. That is the real problem not trainee allowances!
Before I submit my opinion on policy alternatives to solve the problem, I will like to bring to bear that scrapping off trainee allowances will logically usher in the rebirth of brain drain. It does not make legal sense to bond a nurse you have not financed his/her education. And for that matter, if a nurse struggles to survive high school fees on his/her own, he/she should equally have the moral right  to determine who and where he/she wants to work.
Policy Alternatives
The ageless adage – there are many ways of killing a cat – is still true even today. I submit below some of the ways we can finance health education in Ghana bearing in mind that budgetary allocation to the health sector is constrained – about 4.8% of GDP (2011).
Instead of scrapping it off completely, trainee allowances (health and teacher alike) can be granted as repayable bursaries payable by installments over the bond period that trainees are bonded. With this, the onus rests with government to ensure that trainees are promptly placed and hooked onto the public payroll grid to facilitate easy recollection so that the scheme will be self-financing in a revolving manner. A very low interest rate – say 5% p.a can be imposed on it. To this end, if you are unable to complete your training within the stipulated time frame, you begin to receive 50% (half) of your training allowance for the rest of the years you are adding on. While others may be paying 15% interest rate over the three year period corresponding to their training, such a person who defaults in completing his/her studies within the stipulated time period will pay an additional 5%p.a for each additional year. This is one way.
In certain provinces in South Africa, bursaries are available to health trainees based on the composite annual earnings of both father and mother. So that, if one qualifies into a health training school, the annual income of your parents are calculated, if it is below a certain value amount, you qualify for a full training allowance, if it falls within a particular range, you qualify for a partial allowance and if it falls above a certain range, you are out. This is possible in Ghana only if politics is not meddled into it. It is working across the SADC countries. Your father cannot be a doctor and your mother an MP and you expect a bursary from government – that is unfair!
The last option I would suggest is that, if it comes to the worse that trainee allowances should be scrapped, then, school fees should be drastically slashed by over 70% to make it affordable. There should be affordable accommodation. Plus, allowances must be paid trainees on clinical rotation for their accommodation and daily subsistence.
But the notion that trainee allowances should be totally scrapped off is misplaced and therefore should be out-rightly dismissed.
