The link between the baby’s present condition and the three-year-old sisters is that, the three year old might have transferred the virus to the six month old through touch, coughing or sneezing. As it is with shingles the virus was dormant for four month till the time that their mother noted the blister like lesions on the babies back (page17). 4.The baby did not have symptomatic illness when his sister was experiencing it because at the time, the baby was being breast fed by the mother. This means the baby was getting natural antibiotics from his mother through the breast milk. Two moths after the cessation of breast-feeding, the baby did not have that protection anymore.
Unit 4222-265 Causes and spread of infection (ICO2) Understand the causes of infection 1. The differences between bacteria, viruses, fungi and parasites Bacteria belong to a group of single celled microorganisms which are classified as prokaryotes i.e. they do not have membrane bound organelles. They have no true nucleus as the DNA is not contained within a membrane or separated from the rest of the cell, but is coiled up in a region of the cytoplasm called the nucleoid and the cell is surrounded by a cell wall an outer covering that protects the bacterial cell and gives it shape. Viruses are infectious agents, often highly host-specific, consisting of genetic material surrounded by a protein coat.
This usually means that the bacteria have been able to invade either your circulatory system or the lymphatic system and spread. Localised infection - is restricted to a ceratin region of your body 1.5 not washing your hands, not wearing PPE, not storing or cooking foods properly, not cleaning your surroundings, not covering your nose or mouth when sneezing or coughing. 2.1 Food,Acidity,Temperature,Time,Oxygen,& Moisture 2.2 Inhalation, ingestion, injection and absorption 2.3 Common sources of infection include food, water, sick people (colds and flu or winter vomiting virus etc. ), animals and poor housing 2.4 Direct - Person to person (touching, biting ,intercourse)Indirect - coughing, sneezing etc. 2.5compromised immune system,lack of good safety precautions - handwashing, proper cleaning of all surfaces,exposure to more infectious agents (e.g in a hospital setting),handling of body fluids.
Some of the most deadly diseases and devastating epidemics in human history have been caused by bacteria. Cholera Diphtheria Dysentery Plague Pneumonia Tuberculosis Typhoid Typhus VIRUSES A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms, from animals and plants to bacteria and archaea. The average virus is about one one-hundredth the size of the average bacterium. Most viruses are too small to be seen directly with an optical microscope.
3. Which of the following respiratory infections CANNOT be treated with antimicrobial drugs? a. Atypical pneumonia b. Q Fever c. Otitis media d. Common cold e. Tuberculosis 4. Development of a vaccine against rhinoviruses is difficult because a. they are resistant to antibiotics. b. they are resistant to low pH.
It tells that our government is planning to teach people about this deadly disease. In 1970, an eight year old girl named Bilkisunnessa can see the symptoms of smallpox and called the world health organization (WHO). “ She reported the case to a local health worker, and she eventually collected a reward of sixty- to dollars from WHO- a fortune for a girl on Bhola Island”(Preston91). If an eight year old girl can tell the symptom about the smallpox, than if our generation got the right education about smallpox they would be prepared and ready for
Being a Virus, Smallpox cannot be cured, only vaccinated against. It is part of the Orthopoxvirus genus, the Poxviridae virus, and Chordopoxvirinae subfamily. While I couldn’t find a picture I could use as a model to draw and label, I did find information on what the virus looks like, I did find plenty of information on the virus’ appearance. It is a brick-shape measuring 302-350 Nanometers (nm) by 244 to 270 nm. It has a single linear double stranded DNA genome 186 kilobase pairs in size containing a hairpin loop at each end.
4. Cranberry- Decreased elimination of many drugs that are renally excreted. 5. Kava- may increase the effect of barbiturates and alcohol. Pg.
Lesson 1.4 Vaccination - Overview Preface In this unit, students have studied diagnostic tests used to identify disease agents and have examined how antibiotics can be used to treat bacterial infections. In Lesson 1.4, students discuss infectious disease prevention, specifically through vaccination. In the aftermath of the bacterial meningitis cases at Sue’s school, all student medical records are reviewed and any student who did not receive the meningitis vaccine is called back in for immediate immunization. Vaccination is a valuable first line of defense against this debilitating infection and could make the difference between a few isolated cases and a full-blown outbreak. In the first activity of the lesson, students study the history of vaccination through the eyes of scientist Edward Jenner.
2. Explain the term "risk factors" and describe how to reduce your risk of 3 different diseases. (5 points) Risk factors are factors that put your health at risk. To reduce my risk of HIV, I would get as many vaccines as possible.
