Diseases caused by living organisms like viruses and bacteria can be infectious and they can be passed from person to person through body secretions, insects or other means .some of the diseases are discussed here:
Sr.No. |
Name |
Symptoms |
Spread |
Prevention |
1. |
SARS (Severe Acute Respiratory Syndrome) Coronavirus (SARS-CoV). |
Fever, malaise, myalgia, headache, diarrhoea, and shivering |
Close person-to-person contact Transmitted most readily by respiratory droplets. when a person touches a surface or object contaminated with infectious droplets and then touches his or her mouth, nose, or eye |
Frequent hand washing with soap and water or use of an alcohol-based hand rub Avoid contact with others if infected, prevent community spread |
2. |
Rabies Rabies virus (RV) |
viral disease that causes inflammation of the brain in humans and other mammals paralysis, anxiety, insomnia, confusion, agitation, abnormal behavior, paranoia, terror, and hallucinations |
Spread through the saliva of infected animals. Infected animals can spread the virus by biting another animal or a person. |
Vaccines for infected, Proper vaccination of animals also |
3. |
Smallpox Variola virus |
High fever, chills, headache severe back pain, abdominal pain ,vomiting |
Airborne diseases tend to spread fast. Coughing, sneezing, or direct contact with any bodily fluids could spread the smallpox virus. In addition, sharing contaminated clothing or bedding could lead to infection. |
Avoid contact with infected person Do not share clothes etc |
4. |
Syphilis (STI) Treponema pallidum |
Headaches.swollen lymph nodes. fatigue,fever,weight loss,hair loss |
Transmitted through shared needles. Avoid sharing needles if using injected drugs. |
Avoid sharing needles if using injected drugs Have protected Sex |
5. |
Cholera Vibrio cholerae |
Loss of skin elasticity , Dry mucous membranes, including the inside of the mouth, throat, nose, and eyelids , Low blood pressure , Thirst |
Severe watery diarrhea, which can lead to dehydration and even death if untreated. |
Avoid drinking contaminated water |
Choose several infectious diseases and analyze how they are spread, using the chain of infection. Examples...
Choose several infectious diseases and analyze how they are spread, using the chain of infection. Examples are AIDS, rabies, cryptosporidiosis, cholera, malaria, smallpox, syphilis. For each disease, how can the chain of infection be interrupted?
Describe the chain of infection of malaria to analyze how it is spread. Describe how you can break the chain of malaria as well
One only needs to break one link in the chain of infection to prevent the spread of disease. Which link do you think would be the easiest to break to prevent the most recent influenza virus (H1N1) and why? CHAIN OF INFECTION Infectious Disease For an infection to develop, Reservoir Susceptible Host each link of the chain must be connected. Breaking any link of the chain Portal of Entry Portal of Exit can stop the transmission of infection! Mode of...
One only needs to break one link in the chain of infection to prevent the spread of disease. Which link do you think would be the easiest to break to prevent the most recent influenza virus (H1N1) and why? Your answer must include the name of a link on the chain and a reasonable explanation for why that would work. Include how the flu is transmitted. Be sure to cite and reference your sources. Note: Some people refer to intestinal...
Part A - SIR model for the spread of disease Overview. This part of the assignment uses a mix of theory and data to estimate the contact number c=b/k of an epidemic and hence to estimate the infection-spreading parameter b. The point is that once you know the value of b for a certain disease and population, you can use it in your model the next time there is an cpidemic, thus cnabling you to make predictions about the demand...
1. Bacteria such as E.coll and staph belong to which Domain? A. Animalia B. Eukarya C. Archaea D. Bacteria 2. In general terms, prokaryotic cells are cells that? A. Have a nucleus B. Do not have a nucleus. 3. Think about the name E. coli 4X56. In that name which refers to the serotype? A E B. coli C4X56 4. Which of the following best describes the type of bacteria that are important to ecology, and once were thought to...
