droplet infection
  1. Dr Md shahriar kabir B H M S; MPH
    Dr Md shahriar kabir B H M S; MPH Enlightened dr.basuriwala

    Droplet transmission is an infection spread through exposure to virus-containing respiratory droplets (i.e., larger and smaller droplets and particles) exhaled by an infectious person. Transmission is most likely to occur when someone is close to the infectious person, generally within about 6 feet.

    There are several types of disease carriers.
    1. An asymptomatic carrier is a person or organism infected with an infectious disease agent but displays no symptoms.
    2. A genetic carrier is a person or organism that has inherited a genetic trait or mutation but displays no symptoms.
    3. Incubatory carriers, who can transmit the agent during the incubation period before clinical illness begins.
    4. Convalescent carriers, who have recovered from their illness but remain capable of transmitting to others; and
    5. Chronic carriers, who continue to harbor a pathogen for months or even years after their initial infection.

    In epidemiology, the incidence is a measure of the probability of occurrence of a given medical condition in a population within a specified period of time. Although sometimes loosely expressed simply as the number of new cases during some time period, it is better expressed as a proportion or a rate with a denominator.

    Diseases or infections are transmitted in many ways. It may be directly transmitted from one person to another, or by certain bacteria, viruses, protozoa, or fungi. There are two different modes of transmission of diseases:

    A) Direct Transmission– This occurs when the pathogen is transmitted directly from an infected person. For eg., if an open wound comes in contact with the blood of a Hepatitis B infected patient, the wounded person might contract the disease.

    B) Indirect Transmission- When the pathogens are not transmitted directly from the infected person but through vectors such as flies, mosquitoes, ticks, dogs, etc., it is known as indirect transmission.

    Disease Transmission:
    A) Direct Transmission
    1. Person to Person: When an infected person comes in contact with or exchanges body fluids with a non-infected person. A mother can transmit infections to the unborn child via the placenta. A sexually transmitted disease such as gonorrhoea can be transmitted by direct transmission.

    2. Droplet Transmission: The droplets spread during sneezing, speaking, and coughing by an infected person can spread infections. The infections can also spread by touching the nose and mouth with the hands contaminated with infectious droplets. The droplets are so minute that they travel only a short distance before falling. The people nearby might contract infections.

    3. Spread by skin: There are a few infections such as chickenpox, conjunctivitis, head lice, ringworm, etc., which spread when the skin of an infected person comes in contact with the skin of the other person.

    4. Spread through body fluids or blood: A few diseases spread when the body fluids or blood of an infected person come in contact with the mucous membrane or bloodstream of an uninfected person. Diseases such as hepatitis, HIV, cytomegalovirus infections, etc. spread through semen and vaginal fluids, saliva, breastmilk, urine, etc.

    B) Indirect Transmission:
    1. Airborne Transmission: Some infectious agents remain suspended in the air for a long period of time. These pathogens might attack the immune system of a person in contact. E.g. if you enter a room that was initially occupied by a patient of measles, you too might catch the infection.

    2. Contaminated Objects: The objects around us carry pathogens. Touching the infected objects which were initially used by a diseased person might render us diseased. Contaminated blood and medical supplies can also spread infections.

    3. Vector-Borne Diseases: Some infectious agents are transmitted by the blood-sucking insects. The insects feed on hosts such as birds, animals, and humans and carry infectious agents from them. These infections are transmitted to some new host. Malaria and Lyme disease are the two vector-borne diseases.

    4.Food and Drinking Water: Improperly canned and undercooked food is the main source of infections. Water also carries various pathogens from rivers and lakes. It should be boiled or filtered before use. E.coli is transmitted through contaminated food which causes various stomach problems. Botulism is caused by the consumption of improperly canned food. Cholera is one water-borne disease which has affected millions of people consuming contaminated water.

    5.Transmission through Animals: When an infected animal bites or scratches against a person, it transfers the infectious agents to the person. These agents can also be transmitted through animal waste. When diseases are transferred from animals to people, zoonosis occurs. Anthrax (sheep), rabies (dogs), plague (rodents) are some of the diseases transmitted from animals to humans. Pregnant women and people with weak immune systems are more prone to infections.

    6.Environmental Factors: The infectious agents are present in soil, water and plants as well. These agents can be transmitted to people and may cause diseases. For eg., Hookworm is transmitted through contaminated soil. Legionnaires’ disease is spread by water supplied to condensers and cooling towers.

epidemic

pandemic

    Dr Md shahriar kabir B H M S; MPH Enlightened dr.basuriwala

    A pandemic is an epidemic of an infectious disease that has spread across a large region, for instance, multiple continents or worldwide, affecting a substantial number of people. A widespread endemic disease with a stable number of infected people is not a pandemic.

endemic
  1. Dr Md shahriar kabir B H M S; MPH
    Dr Md shahriar kabir B H M S; MPH Enlightened dr.basuriwala

    In epidemiology, an infection is said to be endemic in a population when that infection is constantly maintained at a baseline level in a geographic area without external inputs.

    Epidemiology is the only way of asking some questions in medicine, one way of asking others (and no way at all to ask many). Seven ‘uses’ of epidemiology have been described:

    1. In historical study of the health of the community and of the rise and fall of diseases in the population; useful ‘projections’ into the future may also be possible.

    2. For community diagnosis of the presence, nature and distribution of health and disease among the population, and the dimensions of these in incidence, prevalence, and mortality; taking into account that society is changing and health problems are changing.

    3. To study the workings of health services. This begins with the determination of needs and resources, proceeds to analysis of services in action and, finally, attempts to appraise. Such studies can be comparative between various populations.

    4. To estimate, from the common experience, the individual’s chances and risks of disease.

    5. To help complete the clinical picture by including all types of cases in proportion; by relating clinical disease to the subclinical; by observing secular changes in the character of disease, and its picture in other countries.

    6. In identifying syndromes from the distribution of clinical phenomena among sections of the population.

    7. In the search for causes of health and disease, starting with the discovery of groups with high and low rates, studying these differences in relation to differences in ways of living; and, where possible, testing these notions in the actual practice among populations.
