Q

What are the factors affecting the occurrence of disease?

A

Host Factors: -
* Heredity and genetic factors several diseases, have a genetic origin like Down syndrome
* Age population is more prone to acute and infectious diseases while old population is more prone to chronic diseases and give examples
* For sex females are more prone to diseases than males and vice versa due to different physiological factors and give example
* Health status the general health and nutritional status determines the ability to resist the disease for example a healthy individual response to tuberculate infection by forming a focus. A poor health status will proceed to a manifest disease.
* Previous immunologic experience having past infections, give you the ability to resist, and some even produce a lifelong immunity
* Physiological state pregnancy lactation, and growing children are more susceptible
* Lifestyle, beliefs, and activities, as well as habits like smoking
* Socio-economic status is affected by education occupation, and economic conditions

Environment Factors:-
* The physical environment which includes physical and chemical surroundings, including air, land, gravity, and temperature
* The biological environment which includes animal and plants as well as microorganisms, biological environment, provides human beings with essentials for life, but also pathological organisms that produce disease
* The social and cultural environments which is created by human relations and behaviours which might differ from one country to another or subcultures in the same country

Causative agent: -
* biological agents that cause communicable diseases, such as bacteria and viruses and fungi
* Nutritional deficiencies and excess nutrients, iron deficiency, and obesity
* Chemical agents like poison insecticides, as well as some drugs
* Physical has excessive heat or cold or radiation
* Mechanical Agents causing injuries or accident

Q

What is a risk factor?

A

Factors that make an individual community family, more prone to specific disease due to the presence of a certain factor (maybe know or unknown), but it’s not the direct causative agent The risk factor is related to the host or their self-specific environment.

Q

What are the levels of prevention?

A
  1. Primordial prevention: which is prevention of risk factors through individual and mass education
  2. Primary prevention: which is the prevention of development to the disease entirely,
    ➢ non-specific group of interventions aiming at improving the level of health as health education, environmental sanitation, nutrition, care healthy lifestyle
    ➢ Specific prevention referring to different types of interventions to a specific disease condition:
    * Immunization, active and passive
    * Chemo prophylaxis
    * Nutritional supplementation to prevent specific deficiencies
  3. Secondary prevention is prevention of complication development, progression, and recurrence through early detection of the disease periodic examination for at risk groups and screening tests example cervical cancer adding to this prompt appropriate treatment to achieve cure like this election of antibiotics and the period of treatment and streptococcal pharyngitis to prevent traumatic fever
  4. Tertiary Prevention which is rehabilitation applied to disabled individuals to improve their abilities
    * Might be medical rehabilitation to achieve possible physical ability
    * Social vocational rehabilitation, which includes education and training for suitable job to help earn their own living
    * Psychological rehabilitation to cope with disability, as well as to the family so they can deal with the handicapped and for the environment to welcome him

Q

Levels of practice?

A

On individual level: -
* The case approaches with the presenting condition only (least type of care)
* The total person approach denotes that the person is assessed for it’s for the medical psychological and social aspects to reach proper diagnosis, appropriate line of treatment

Family level: -
* Practice considers the whole family as one unit for care
* It requires a will integrated team of family, physicians, capable of providing quality healthcare to all members with the family
* Also requires family health file and proper record system

The community level: -
* The health services provided to the community should be appropriate to address. The health needs a particular community to promote health and well-being to prevent and control priority, health problems, and treat any disease conditions.

Q

What are the factors affecting incubation Period?

A

A. Dose And route of infection: for example, a higher dose of salmonella is associated with faster symptoms and shorter incubation. Period.

B. Biological factors of the infected host: some people are more susceptible to faster, disease, progression and complications because of their age genetics or the competence of their immune system. Incubation period of aids tends to be longer in eight HIV infected individuals who are young.

C. Pharmacologic factors: for example, the incubation period of aids will substantially lengthen by the use of effective anti-retroviral therapy

Q

Define carrier and the types of carriers?

A

A carrier is an apparently healthy individual who is infected and harbours pathogenic organisms as a focus of an infection in different part of their body where the organism finds a portal of exit to spread the infection

Types of carriers: -
* Incubatory carrier to transmit the disease during the incubation period.

  • Convalescent carrier transmitting the disease during the convalescent period (after recovery of symptoms)
  • Contact carrier: contact might be infected if came in contact with an infected person
  • Healthy carrier like the inhabitants of endemic areas of infectious diseases usually the infections are eliminated spontaneously in two weeks except for HHBV one year (If asked human reservoir infection, just add cases, individuals with symptomatic illness showing disease manifestation)

Q

Compare between direct and indirect droplet infection?

A

Direct droplet infection both reservoir and host are found together in the same place within 6 feet (1.8 meters) and the host is infected through direct inhalation of the spray (fine droplets) of reservoir. Kissing is a potential method of direct infection.

➢ Predisposing Factors include crowded areas with ill ventilation as camps

Indirect infection reservoir host do not come together and infection is transmitted by droplet nuclei, which are minute residues of spray droplets after evaporation of water, it measure <=5 µm in diameter making them easily suspended and carried by air current for longer period of time.

41
What are the reasons of outbreak occurring?
1. changing the agent itself like an increase in the amount or the virulence of an agent Where it’s introduction into a new setting 2. The host becomes less immune or may have risk factors that renders them more susceptible 3. Environment, favourable for interaction between host agent, for essence enhancing mode of transmission

Prevention of congenital infection by treatment of mother during pregnancy by highly active antiretroviral therapy (HAART). HIV women should not breast feed their infants. 7. Immunization of HIV infected children with BCG, DPT, measles, MMR, hepatitis B vaccines to guard against infection of the corresponding diseases in highly susceptible immune­ compromised persons.
68
Control of HIV
1. Isolation of HIV infected person is unnecessary and ineffective 2. Specific treatment: ■ HIV can be suppressed by lifelong treatment with combination ART (antiretroviral therapy), consisting of 3 or more ARV (antiretroviral) drugs. ■ ART does not cure HIV infection but controls viral replication within a person's body and allows individual's 'immune system to strengthen and regain the capacity to fight off infections. ■ Treatment also includes drugs for prophylaxis / treatment of opportunistic infections. Contacts to HIV/ AIDS: 1- Listing of the sexual and needle sharing partners. Confidential HIV testing and counseling should be offered to them 2- No isolation or segregation, just follow up is recommended every 3 months by staff from the National AIDS program. 3- No specific protection measures, just highlight on the general measures -(given before)­ through health education to prevention of further exposure( s) to infection.
69
What is the post exposure prophylaxis for HIV
* Post-exposure prophylaxis (PEP) is the use of ARV drugs within 48 hours of exposure to HIV in order to prevent infection. * A three drug ARV regimen is recommended. * PEP is recommended for healthcare workers following needle stick injuries in the workplace.

Control of Hepatitis C
* Case-finding, by serologic testing of suspected cases. * Specific therapy: The goal is to prevent complications of HCV and to eradicate infection. Patients legible for treatment are selected carefully according to the degree of liver fibrosis, coma, liver functions and blood picture. Direct acting antiviral agents (DAAs), which work as HCV protease inhibitors, are currently used as the main treatment regimen.
74
The Ministry of Health Plan of Action for prevention, care and treatment of viral hepatitis includes the following topic areas:
1) Strengthening surveillance of acute and chronic viral hepatitis to: * Monitor trends of disease. * Assess risk factors. * Monitor prevention programs. * Detect outbreaks. 2) Reducing transmission of viral hepatitis through: * Promoting infection control practices in governmental hospitals as well as private healthcare settings. * Establishing governmental commitment to support policies that ensure infection control practices in Egypt. * Reducing occupational transmission of viral hepatitis. * Strengthening monitoring and evaluation programs for ensuring implementation of infection control programs. 3) Improving blood safety through: * Establishing governmental commitment to support policies that ensure the safety and adequacy of national blood supply. * Building a sustainable base of safe blood donors to maintain adequate and safe blood supplies. * Applying the national standards in all activities related to production and testing of blood. 4) Increasing awareness about viral hepatitis through health education. 5) Eliminating transmission of vaccine-preventable viral hepatitis through: * Achieving universal hepatitis B vaccination for populations at high risk for infection or complications. * Ensuring that all newborns receive the hepatitis B birth dose as soon as possible following birth (24 hours). 6) Improving care and treatment to prevent complications through: * Providing safe, effective, and affordable treatment to patients with chronic hepatitis B and C. * Improving care and treatment of patients with advanced forms of liver diseases. * Increasing political commitment to support global pricing for viral hepatitis drugs and to increase access to new drugs in Egypt and worldwide.
75
HCV screening in Egypt is a priority cost effective public health program due to many facts:
* Prevalence of HCV seropositivity was about 10% and the prevalence of HCV RNA positivity was 7% among the 15 - 59 years age groups. Approximately 3.7 million persons had chronic HCV infection in the age group 15-59 as per EDHS-2015 * A significant number of those who are chronically infected will develop cirrhosis or liver cancer. * New HCV infections are usually asymptomatic, few people are diagnosed when the infection is recent. Chronic HCV infection is also often undiagnosed because it remains asymptomatic until decades after jnfection when symptoms develop secondary to serious liver damage "WHO calls HCV as silent enemy". * Currently, antiviral medicines can cure more than 95% of persons with hepatitis C infection, thereby reducing the risk of death from cirrhosis and liver cancer, but access to diagnosis and treatment is low.

What do you have to do if a dog bites an adult or a child in the street? 4 different problems
You have the risk of 4 main problems: * Pyogenic infections: staph, stept. Infections => (use antibiotics) * The risk of tetanus (see algorithm for contaminated wounds) * The risk of rabies (Give HDCV + RIG if indicated) * Besides: the lacerated wounds & cut nerves and tendons
80
What do you have to do for a rabies bite?
The first thing ( without thinking) is to deal with the wound: ■ Clean the wound with plenty of water+ 20.0% soap solution, 70.0 % alcohol ■ Never suture the wound (except in life threatening conditions or excessive bleeding) If: ■ The animal escaped, or died/ killed and found Negri bodies, or ■ Severe multiple wounds in the head and neck Then, give HRIG and start active immunization immediately and complete the doses You have to ask about the history of previous immunization: ■ If no history: Give full doses. ■ If previously immunized within 2 years: give fewer doses. o HDCV: give only 2 doses, 3 ·days apart. If: low severity wound, and the animal is alive, confined, arrested, or captured Then, start active immunization, and observe the animal for 10 days. ■ If the animal dies, complete the doses. ■ If the animal kept alive, stop the doses. Conditions where RIG is Not given: ■ Minor scratches, abrasions or bruises without bleeding ■ The wound was not contaminated with animal's saliva (e.g., there was a barrier of clothes) ■ If the bitten individual had full post exposure vaccination in the last 5 years. ■ After 10 days or more of the bites with no signs of rabies on the animal

Causative agent: The yellow fever virus of the family Flaviviridae. Reservoir and vector of Yellow Fever: In Jungle yellow fever, the main reservoirs in the forest area are nonhuman primates, and forest mosquito (Aedes or Haemagogus species) is the vector. In Urban yellow fever, the reservoir is man and Aedes aegypti mosquito is the vector. Blood of infected individuals and monkeys thru mosquito bites MOT: bite of infective female Aedes aegypti mosquitoes (man-mosquito-man). and bite of several species of genus Aedes or Haemagogus (monkey-mosquito­ man).
83
Prevention of yellow fever
1) General Prevention a. Environmental sanitation: Eradication or control of mosquito vector . Control measures are directed to breeding places and use of insecticides. b. Health education: to the target population in endemic area to follow the methods of protection from mosquito bites ( e.g. protective clothing, bed nets, repellents, etc.) 2) Specific Prevention: Immunization: Active Immunization: 17 D vaccine: * It is the most effective preventive measure for yellow fever. * It gives 99% immunity. Antibodies appear 7-10 days after immunization and persist for life. International health regulation considers that the yellow fever vaccines approved by WHO provide protection against infection starting 10 days following the administration of the vaccine; this protection continues for the lifetime of the person vaccinated. * The vaccine is given to international travelers ( all travelers 2:9 months of age) coming from or going to endemic countries.
84
How is Egypt protected from Yellow Fever?
Yell ow fever is not present in Egypt and is rare in other areas such as eastern Africa despite the wide spread of the vector Aedes aegypti. Cross immunity due to infection by other flavi viruses ( e.g. Dengue, West Nile), provides an "ecological barrier" that prevents the occurrence of yellow fever in these areas.

86
Elimination of lymphatic filariasis (Bancroftian) in Egypt:
1. Interruption of transmission, and care for those who already .have the disease. To interrupt the transmission, the entire population at risk must be covered by mass drug administration (MDA) for a period long enough to ensure that the level of microfilariae in the blood remains * below that which is necessary to sustain transmission .. The recommended MDA includes a single annual dose of combinations of Diethylcarbamizine citrate (DEC) and Albendazole for 4-6 years. The regular use of DEC­ medicated cooking salt for 1-2 years has also been used in some settings to interrupt the transmission cycle. Mass administration of these drugs has the two-fold purpose of preventing future cases of lymphatic filariasis and control the infection for those people who are already suffering from the disease. Alleviate the suffering of affected people through morbidity management and disability prevention.

Census is the enumeration of all persons in different parts of the country at the specific time as well as collecting demographic and social economic data of the population ( age, sex, religion, education, occupation, etc) using a special questionnaire form by a trained enumerator, usually every 10 years. Value of census: - * Provides information about the characteristic features of population. * Provides basic data required for calculation of statistical indicators; example, vital rates * The census data along fertility and mortality indicators are used in making population projection (expected population changes) which is essential for planning the future needs of a population as education, jobs, etc

What are the three components of a population change? And three ways to measure it?
* Births * Deaths * migration Measured by rate of natural increase, growth rate, doubling time of population growth
147
Outline the stages of demographic transition?
* Stage one: high birth rate and high death rate = little or no increase in the population (high potential population) * Stage two: high birth rate and falling death rate = high growth rate (transitional population) * Stage three: declining birth rate and relatively low death rate = slow population growth (balanced population) * Stage four: low birth rate and low death rate = very low or no population growth
148
Characteristics of the population pyramid?
* The base width: presents the proportion of the young age group * The top width: presents the proportion of the old age group * The height: presents duration of life expectancy * The symmetry: presents the similarity/differences in proportion of males and females in the different age group * The shape of the sides: maybe smooth with depressions (emmigration out the country) or with bulging (immigration or baby boom)
149
Discuss different Profiles of the different population pyramids?
The age-sex composition may show: - * expensive population: large number of people in the younger ages (developing countries) * Constrictive population: smaller number of people in the younger ages (transitional phase from high to low birth rates) * Stationary population: has roughly equal number of people in all age ranges and of gradually at older ages; example, developed countries
150
What is age-dependency ratio and what does it indicate?
It’s the ratio of person in the dependent age (<15 and >64) to those at the working age (15- 64) usually expressed as the number of dependent persons for every 100-working person. It indicates the economic burden that the working portion of the population must carry, the higher the ratio, the heavier the dependency. Burden is one of the factors that affect health, social pattern and labour for quality
151
What are the three main dimensions of Egyptian problems?
* Rapid population growth: Egypt population ranks 15th in the world. * Improper population distribution where 97% of Egyptians are concentrated in about 4% of the total of 1 million km² * Improper population characteristics as high illiteracy rate, high level of unemployment, high age dependency ratio, and minor role of women in the development programs.
152
What are the objectives of the national population policy?
* Decreasing rate of population growth * Achieving better population geographic distribution * Promoting the population characteristics
153
What are the strategies to achieve the objectives of the national population policy?
The national socioeconomic development programs as a long-term policy; examples, education and economic development Family planning program is a short-term policy that aim at slowing down population growth so that the country can allocated resources towards development programs rather than service programs Strategy is focusing on FIVE parameters: family planning, youth, health, woman empowerment, and communication/awareness
154
Enlist to the factors affecting fertility?
* Age and sex structure of the population: the higher the proportion of young women in reproductive age the higher the fertility rates * Fecundity: it is the physiological capacity of couples to reproduce * Marriage rate * Age at marriage for girls: the younger, the higher the rates * Economic status: the higher, the lower the rates * Education: better education is associated with low fertility rates * Woman status: the better the woman status in the community with good access to education, work and health services the lower the fertility * Family planning method use: the availability and accessibility to them is associated with high contraception and subsequently low fertility rates * Presence of motives for high fertility; example, stable marriage, religious or personal motive
155
Mention some motives for high fertility ?
* Health: high infant/child mortality motivates the family to have more children * Economically children support the family by being employed at young age * Family welfare where they believe large families are empowered and sons continue the family name * Stable marriages as many children help prevent divorce and infidelity * Religious motive * Personal motive: manliness in high fertility * Dislike of contraception * National welfare: stronger nation when having high population
156
What are the objectives of the family planning program?
* Increase the contraceptive prevalence rate through increasing availability and accessibility of family planning services and methods . * Increase the demand for family planning services through information, education and communication programs. * Follow up services to decrease discontinuation rates for contraception * Decreased contraceptive method failure rate * Reduce the unmet needs for family plan
157
Who are the priority groups for family planning programs?
1. Teenage pregnancy as it’s too early and may lead to spontaneous abortion or prematurity. 2. Late pregnancy above 35 years of age as it increases risk of down syndrome. 3. Short spacing negatively influence, proper breast-feeding and process of rebuilding maternal nutritional stores. 4. Multi-parity (5 or more) predisposes to hypertension, diabetes, renal diseases, and genital prolapse.
158
What are the impact indicators of family planning program?
* Crude birth rate * General fertility rate * Fecundity rate * Age specific fertility rate * Total fertility rate * Other indicators as maternal morbidity, maternal mortality
159
What are the outcome indicators of family planning program?
* Contraceptive prevalence rate * Contraceptive discontinuation rate * Contraceptive failure rate * The unmet needs for family planning
