Study Notes
Bacterial and Viral Diseases
- Leptospirosis is a bacterial disease caused by Leptospira bacteria, transmitted through urine of infected animals or contaminated environment.
- Control methods include vaccination and rodent control, and prevention involves wearing protective clothing and avoiding contaminated water.
Viral Diseases
- SARS (Severe Acute Respiratory Syndrome) is a viral respiratory disease caused by SARS-CoV, which led to a global outbreak in 2003.
- COVID-19 is a member of the SARS-CoV family and is currently a major global problem.
Mosquito-Borne Diseases
- Chikungunya is a viral disease transmitted to humans by infected mosquitoes, causing fever and severe joint pain (arthralgia).
Bacterial Infections
- Meningococcemia is a bacterial infection of the blood caused by Neisseria meningitides, which can have a high mortality rate if untreated.
- Transmission occurs from person-to-person through respiratory secretions.
- Patients require antibiotic treatment through IV or IM routes as soon as diagnosis is suspected.
Viral Infections
- Hand, Foot, and Mouth Disease is caused by Coxsackievirus and enterovirus, with no available vaccine.
- Avian Influenza (A(H7N9)) is a subtype of influenza viruses detected in birds and humans in China since 2013.
- Influenza A(H1N1) is a flu virus that was first detected in 2009, similar to those found in pigs.
- Vaccines have been developed to protect against the H1N1 virus.
Stages of Infectious Diseases
- Incubation stage: time between exposure and appearance of symptoms, varying from hours to months.
- Prodromal stage: body reacts to the presence of pathogen, lasting about 1-2 days.
- Acute stage: highest point of disease, with signs and symptoms for diagnosis.
- Declining stage: symptoms start to subside, but patient is still recovering.
- Convalescent stage: patient recovers strength and returns to normal state of health.
Terminology
- Morbidity: disease state of an individual or occurrence of illness in a population.
- Mortality: number of deaths in a population.
- Acute Respiratory Infections: infection in the upper or lower respiratory tract, preventing breathing.
- Bronchitis: inflammation of the bronchial tubes, with signs and symptoms including wheezing, cough, chest discomfort, and low fever.
