The Hard Work will be Worth It!

                The Hard Work will be Worth It!

Blog by Emaras One: Feb 25, 2016

Do you sometimes wonder how on earth you will ever be able to reach the levels of those who are successful

Do you think that's just going to be too hard and doesn't happen to 'people like you'?
One thing's for sure...if you don't try and persist, and then try some more, you're never going to get anywhere, either in business or in life in general.
It's a great idea to take inspiration from those who have already achieved the dizzy heights you dream of; after all, they've already 'been there and done that'. Learn from their mistakes, study their lives, emulate their successes and before you know it, you will begin to think and act in the same way.
Remember the Law of Attraction and the importance of visualization. Make that mood board, add to it every day, study it and FEEL what it's going to be like when you reach your dreams.
You never know, those who are your idols could end up becoming your followers or even your rivals!

Have a wonderful evening fellow entrepreneurs.

Life Cycle of an Aedes Mosquito which spread zika viruse


Life Cycle of an Aedes Mosquito

Under optimal conditions, the egg of an Aedes mosquito can hatch into a larva in less than a day. The larva then takes about four days to develop into a pupa, from which an adult mosquito will emerge after two days. Three days after the mosquito has bitten a person and taken in blood, it will lay eggs, and the cycle begins again.


Did you know?

  • 1. Only the female Aedes mosquito bites as it needs the protein in blood to develop its eggs.
  • 2. The mosquito becomes infective approximately seven days after it has bitten a person carrying the virus. This is the     extrinsic incubation period, during which time the virus replicates in the mosquito and reaches the salivary glands.
  • 3. Peak biting is at dawn and dusk.
  • 4. The average lifespan of an Aedes mosquito in Nature is two weeks.
  • 5. The mosquito can lay eggs about three times in its lifetime, and about 100 eggs are produced each time.
  • 6. The eggs can lie dormant in dry conditions for up to about nine months, after which they can hatch if exposed to     favourable conditions, i.e. water and food.

Zika virus...


Zika virus

 

Fact sheet
Updated February 2016

Key facts

  • Zika virus disease is caused by a virus transmitted by Aedes mosquitoes.
  • People with Zika virus disease usually have symptoms that can include mild fever, skin rashes, conjunctivitis, muscle and joint pain, malaise or headache. These symptoms normally last for 2-7 days.
  • There is no specific treatment or vaccine currently available.
  • The best form of prevention is protection against mosquito bites.
  • The virus is known to circulate in Africa, the Americas, Asia and the Pacific.

Introduction

Zika virus is an emerging mosquito-borne virus that was first identified in Uganda in 1947 in rhesus monkeys through a monitoring network of sylvatic yellow fever. It was subsequently identified in humans in 1952 in Uganda and the United Republic of Tanzania. Outbreaks of Zika virus disease have been recorded in Africa, the Americas, Asia and the Pacific.
  • Genre: Flavivirus
  • Vector: Aedes mosquitoes (which usually bite during the morning and late afternoon/evening hours)
  • Reservoir: Unknown



Signs and Symptoms

The incubation period (the time from exposure to symptoms) of Zika virus disease is not clear, but is likely to be a few days. The symptoms are similar to other arbovirus infections such as dengue, and include fever, skin rashes, conjunctivitis, muscle and joint pain, malaise, and headache. These symptoms are usually mild and last for 2-7 days.

Potential complications of Zika virus disease

During large outbreaks in French Polynesia and Brazil in 2013 and 2015 respectively, national health authorities reported potential neurological and auto-immune complications of Zika virus disease. Recently in Brazil, local health authorities have observed an increase in Guillain-Barré syndrome which coincided with Zika virus infections in the general public, as well as an increase in babies born with microcephaly in northeast Brazil. Agencies investigating the Zika outbreaks are finding an increasing body of evidence about the link between Zika virus and microcephaly. However, more investigation is needed to better understand the relationship between microcephaly in babies and the Zika virus. Other potential causes are also being investigated.

Transmission

Zika virus is transmitted to people through the bite of an infected mosquito from the Aedes genus, mainly Aedes aegypti in tropical regions. This is the same mosquito that transmits dengue, chikungunya and yellow fever.
Zika virus disease outbreaks were reported for the first time from the Pacific in 2007 and 2013 (Yap and French Polynesia, respectively), and in 2015 from the Americas (Brazil and Colombia) and Africa (Cape Verde). In addition, more than 13 countries in the Americas have reported sporadic Zika virus infections indicating rapid geographic expansion of Zika virus.

Diagnosis

Infection with Zika virus may be suspected based on symptoms and recent history (e.g. residence or travel to an area where Zika virus is known to be present). Zika virus diagnosis can only be confirmed by laboratory testing for the presence of Zika virus RNA in the blood or other body fluids, such as urine or saliva.

Prevention

Mosquitoes and their breeding sites pose a significant risk factor for Zika virus infection. Prevention and control relies on reducing mosquitoes through source reduction (removal and modification of breeding sites) and reducing contact between mosquitoes and people.
This can be done by using insect repellent; wearing clothes (preferably light-coloured) that cover as much of the body as possible; using physical barriers such as screens, closed doors and windows; and sleeping under mosquito nets. It is also important to empty, clean or cover containers that can hold water such as buckets, flower pots or tyres, so that places where mosquitoes can breed are removed.
Special attention and help should be given to those who may not be able to protect themselves adequately, such as young children, the sick or elderly.
During outbreaks, health authorities may advise that spraying of insecticides be carried out. Insecticides recommended by the WHO Pesticide Evaluation Scheme may also be used as larvicides to treat relatively large water containers.
Travellers should take the basic precautions described above to protect themselves from mosquito bites.

Treatment

Zika virus disease is usually relatively mild and requires no specific treatment. People sick with Zika virus should get plenty of rest, drink enough fluids, and treat pain and fever with common medicines. If symptoms worsen, they should seek medical care and advice. There is currently no vaccine available.

WHO response

WHO is supporting countries to control Zika virus disease through:
  • Define and prioritize research into Zika virus disease by convening experts and partners.
  • Enhance surveillance of Zika virus and potential complications.
  • Strengthen capacity in risk communication to help countries meet their commitments under the International Health Regulations.
  • Provide training on clinical management, diagnosis and vector control including through a number of WHO Collaborating Centres.
  • Strengthen the capacity of laboratories to detect the virus.
  • Support health authorities to implement vector control strategies aimed at reducing Aedes mosquito populations such as providing larvicide to treat standing water sites that cannot be treated in other ways, such as cleaning, emptying, and covering them.
  • Prepare recommendations for clinical care and follow-up of people with Zika virus, in collaboration with experts and other health agencies.

[Morals and Values]
           Private, personal standards of what is right and wrong in conduct, character and attitude







Principles of ethics and integrity 4
Dr. Sikyewunda William
M.B;Ch.B (Makerere)
MPH Wales
Morals and Values
Definition of Morality
        Private, personal standards of what is right and wrong in conduct, character and attitude
        Principles concerning right and wrong or good and bad behavior
        Yardsticks which work as prescription to human behavior
        Norms of conduct whose legitimacy is justified on the grounds that they are good or right or necessary for social welfare or social life
        Morals may be created by and defined by society, religion or individual conscience

Socially Acceptable Moral Standard
        Unfair for group to impose its moral ideas on rest of population
        No hard and fast rule as to socially acceptable moral standard
        General behavioral expectation of person living in given society
        In medical profession seniority recognized and junior practitioners expected to greet seniors with respect
        Morals start from family

                               Similarities between Law and Morality
        Both prescribe and proscribe conducts in given society
        Supplement and reinforce each other
        Law operates within framework of morality which prescribes obedience to rules established by custom or laid down by authority
        Both have some form of sanction - law takes coercion and morality takes reprobation, repulsion and ostracism

                                Differences between law and morality
        Law does not punish every omission while morality punishes every omission
        Law continuously evolving while morality is constant
        Law legislated, coercive by nature, while morality is neither of the two
        Morality easily enforced, but law more difficult to enforce
        Locus of legal control is external; whereas that of morality is internal
                                   
                              Terms
        Morality refers to the requirements for people to live together in society
        Moral behaviour - way person perceives these requirements and responds to them
        Moral development is pattern of change in moral behaviour with age

        Moral Development
        Process of learning to tell difference between right and wrong
        Complex process begins in childhood and continues throughout life
        Theories of moral development attempt to answer questions
        How person becomes moral
        What factors influence way person behaves in moral situation
                     Lawrence Kohlberg’s Theory of Moral Development
        Specifically addressed moral development in children and adults
        Focused on reasons why individual makes decision
        Moral development progresses through 3 levels and 6 stages
        Levels and stages not linked to specific developmental stage
              
               Levels of Kohlberg’s Moral Development Process
        1. Pre-moral or pre-conventional level – children responsive to cultural values and labels interpreted in terms of consequence of action - punishment or reward
        2. Conventional level – individual concerned about maintaining expectations of family, group or nation for conformity and loyalty to own expectations and society’s
        3. Post conventional, autonomous or principle level – individual makes effort to define valid values and principles

                                 Stages in the levels
        Level and Stages
Level 1: Pre-conventional
        Stage 1 – Punishment and obedience orientation
        Stage 2 – Instrumental relativist orientation
        Explanation and Examples 
        Action wrong if punished and right otherwise e.g. Health worker attending to duty  only for fear of being sacked
        Action only for self satisfaction e.g. child accepting treatment due to being given sweets

                               Stages in the levels
        Level and Stages
Level 2: Conventional
        Stage 3 – Interpersonal concordance
        Stage 4 – Law and order orientation
        Explanation and Examples
        Action taken to earn approval from other person e.g. In-charge allowing colleague off-duty for personal reasons
        Right behavior is following the rules e.g. Nurse refusing relative to visit patient after visiting time
                                Stages in the levels
        Level and Stages
        Level 3: Post-conventional
        Stage 5 – Social contract, legalistic orientation
        Stage 6 – Universal ethical principles
        Explanation and Examples
        Adherence to laws that protect rights of others, considering values and opinions of others and avoiding violation e.g. ensuring worship for patients
        Universal moral principles internalized and respect for rights upheld e.g. whistle-blowing against errant boss
       

                     Carol Gilligan’s Stages of Moral Development
3 stages with each ending with transition of discomfort with behavior
        Stage 1 – caring for oneself – focus is survival. Ends when individual views this as selfish hence seeing need for relationships with others
        Stage 2 – Caring for others – recognition and responsibility  Ends with realization of need for balance with self care
        Stage 3 – Caring for self and others – balance between caring for others and for self. Responsibility now for self and others
             
                                            VALUES
Definition of Value
        Freely chosen, enduring belief or attitude about worth of something
        Worth ascribed to person or object determines behavior towards  person or handling of object
        Value set – small group of values held internally along continuum from most important to least important forming value system
        Value systems basic to way of life, giving direction to behavior based on decisions and choices
                                        
                                      BELIEF, ATTITUDE
        Interpretation or conclusion that one accepts to be true based more on faith than fact without necessarily involving value
        Attitudes – mental positions of feelings towards something continuing over time, whereas belief may last only briefly
        Attitudes often judged as bad or good, positive or negative, whereas beliefs judged as correct or incorrect
        Attitudes have thinking and behavioral aspects, but feelings important component, vary greatly among individuals
                                         TYPES OF VALUES
        Values influence decisions and actions
        6 basic types of values underlying interests and motives
        Each person’s value orientation is unique blend of types with one  predominant
        Identifying own orientation and that of others helps understanding  people’s perception of situations and choices of action

                                    TYPES OF VALUES
        Theoretical: person values truth and empiricism, critical, rational, keeps records and works with facts on ground
        Economic: interested in what is practical and useful, not in irrelevance and wasting resources
        Aesthetic: values beauty, form and harmony, dislikes untidiness and believes in orderliness
        Social: values humans, loving, kind, sympathetic and unselfish. Enjoys  teamwork
        Political: values power, interested in leading, directing and recognition.         . Religious: values unity

                                      Development of Values
        Values formed over lifetime through information from environment, family, and society
        People internalize values and perceive them as personal values
        People need to inculcate societal values to feel accepted, and need personal values to have sense of individuality
        Health professional values acquired during socialization into Health sector
                             
                     ESSENTIAL HEALTH PROVIDER VALUES
        Specific professional health provider values stated in code of ethics, in standards of practice and in legal system
Four important values of health provider
        Strong commitment to service
        Belief in dignity and worth of each person
        Commitment to education
        Professional autonomy

                                     VALUE CLARIFICATION
        Process  of identifying, examining and developing individual values
        No one set of values is right for everyone
        When people identify their values, they can retain or change them freely by choice, rather than unconsciously 
        Promotes personal growth by fostering awareness, empathy, and insight 
        Process has 7 steps centered on 3 main activities; choosing (Cognitive), prizing (Affective), and acting (Behavioural)
       
                         CLARIFYING HEALTH WORKER’S VALUES
        Health workers and students need to examine values they hold about life, health, illness and death
        Professionals need to be “value neutral” and non-judgmental
        Health worker has commitment to clients regardless of values held
        Health care professional may have moral obligation to respond to  client’s value that may cause harm to client and/or others e.g. CSW’s values

                                  CLARIFYING CLIENT’S VALUES
        Client ignores health professional’s advice
        Client exhibits inconsistent communication or behavior e.g. pregnant woman continues to drink alcohol and smoke
        Client has history of numerous admissions to health agency for same problem
        Client confused and uncertain about course of action
In such situations health care provider should help client clarify values
                      
              CLARIFYING CLIENT’S VALUES
        List alternatives
        Examine possible consequences of choice
        Choose freely
        Feel good about choice
        Affirm choice
        Act choice
        Act with pattern

THE SCIENCE OF DEATH AND DYING ...



THE SCIENCE OF  DEATH AND  DYING 

UNDERSTAND ALL ABOUT DEATH AND HOW TO RECOVER FROM ITS EFFECT.

DEATH AND DYING
Death is the permanent termination of the biological functions that sustain a livingorganism. Phenomena which commonly bring about death include old age, predation, malnutrition, disease, and accidents or trauma resulting in terminal injury.
Death as aresult of age can be seen as the final conclusion of an individual’s developmental cycle. Death is viewed differently depending on age, culture and religious beliefs. Irrespective of who you are, no one wishes to die.

ATTITUDES TOWARD DEATH 
Childhood
Before they attain the ability to perform concrete operations, children do not have an accurate conception to death. They believe death is reversible and can be avoided
Adolescence
Although adolescentsunderstand the nature of death, they do not have a healthy respect for its implications. An adolescent thinks only on how to live not how long to live. In fact they may associate death with glamour or daring deeds of heroism. They would always want to do extreme activities to defy death hence making death not to be feared.
Young Adults
Young adults are at the peak of their physical and sensory abilities and believe that the future has much to offer them. They rarely think of their own death. Consequently the occurrence of life threatening illness usually provokes extreme anger and rage. Young adults with terminal illness are typically very poor hospital patients; they feel death is unfair and they are being robbed of their future.
Middle Adult hood
During the middle ages noticeable physical changes (signs of aging e.g. wrinkled face, weakness in bones etc) in addition to experiences of death of loved ones and other people, make them aware of death. This awareness can lead to a middle life crisis, where an individual may start behaving like they are in an earlier stage like adolescence or improve dietary and exercise habits to become more physically fit and live a long life.
Late adulthood
The elderly have reached a stage of understanding and accepting of this eventuality than the young ones. According to Erik Erikson, at this age they face the crisis of generatively verses stagnation. Generatively in the sense that they have parented children and achieved in their life and also given back to society.With this perspective death is not a very big issue. But if they have not achieved as above, they feel stagnated and may wish to have more time so as to be able to realize achievement.
Death and religious beliefs
All religions, Christians, hindu, islam believe in life after death. The following bible verses, John 11:25, John 3:16,luke 16:19-31 articulate the fact that there is life after death. Islamic doctrine holds that human existence continues after the death of the human body in the form of spiritual and physical resurrection. Faith in life after death is one of the six fundamental beliefs required of a Muslim to complete his faith



Death and cultural beliefs
Almost all cultural beliefs believe in life after death, they perform rituals which are perceived to prepare one for the next world.  Placing the body of the deceased on high ground (a mountain) and leaving it for birds of prey to dispose of, as in Tibet. Birds of prey are carriers of the soul to the heavens

Qn.Describe some culture practices done by your tribe to prepare someone for life after death

Confronting death
Ultimately we must all face our impending death. How will we react?. According to Elisabeth Kubler-Rose, terminally ill patients typically go through five stages in dealing with and understanding death.
Stage one:-Denial
The typical reaction is, this can’t happen to me, because friends and family members may also deny the reality of death the patient feels isolated and has no one with whom to talk.
Stage two:-Anger
Once the reality has been confronted, the not me attitude changes to why me?, complaint. Young and healthy individuals are envied. To move beyond this stage, patients must express their anger and rage.
Stage three:-Bargaining
Once rage and anger have been expressed, terminally ill person bargains for additional time. Such bargains often take the form of prayers such as I will lead a better life if I can only live until…..
Stage four:- Depression
Depression often follows the bargaining stage. As with anger depression should not be hidden. Only by directly confronting and experiencing the normal feelings of sadness and grief will the person be able to progress to the stage of acceptance
Stage five:-acceptances
This stage is characterized by a feeling of being at peace with oneself. Unfinished business such as setting ones finances in order and seeing old friends for a final time, has been taken care of and the person accepts the fact that time is near.



BEREAVEMENT, GRIEF AND SUPPORT
Death brings numerous changed and adjustments for those who are left behind. Roles change, a wife becomes a widow, a husband a widower and a child an orphan
The emotional and role changes that followdeath are called bereavement, all people whose emotions and role Ts change are known as the bereaved. E.g. widows and widowers must assume the responsibility of the deceased spouse and orphans must adjust to a totally new environment.
Grief
The emotional changes associated with bereavement. It’s usually quit difficult to adjust to emotions of bereavement, this process usually progresses through four stages.
Stage one-shock and denial
These reactions serve to protect the individual from the pain of what happens. The stage may last as long as two or three months or even more
Stage two-intense concern
This is characterized by intense concern for perpetuating/extending the memory of the dead person. All thoughts and concern are on the dead person.
Stage three-Despair and depression
Is often characterized by confused thinking and anger. Irrational behaviors e.g. selling ones house and moving away, not caring for one’s self etc
Stage four-Recovery
When the bereaved person shows renewed interest in normal daily activities, he or she has reached the recovery stage. Social support is a key ingredient ina successful copying with death and bereavement.
