Pertussis is an infectious disease caused by the Bordetella pertussis bacterium, which was first isolated in 1906. The bacteria attaches to respiratory cilia and produces toxins that paralyze the cilia, causing inflammation of the respiratory tract and difficulty expelling pulmonary secretions. It is a highly contagious disease transmitted through coughing or sneezing within close contact, and has an incubation period of 7-10 days followed by three illness stages: catarrhal, paroxysmal cough, and convalescence.

Bordetella pertussis
Pertussis, or whooping cough, is caused by the bacterium Bordetella pertussis. It is highly contagious and can cause serious illness, especially in infants. The disease progresses through catarrhal, paroxysmal, and convalescent stages. Symptoms include intense coughing fits that can end in a "whooping" sound. Treatment focuses on hydration and rest. Universal childhood vaccination against pertussis significantly reduced cases, though neither natural infection nor vaccines provide lifelong immunity. Booster shots are recommended to maintain protection against this respiratory illness.
Influenza
The influenza virus, commonly called "the flu", infects the respiratory tract of humans and animals. It is caused by RNA viruses in the Orthomyxoviridae family. There are three main types of influenza viruses - A, B, and C. Common symptoms of the flu include fever, cough, sore throat, runny nose, headache, muscle aches, and fatigue. Treatment focuses on vaccination with flu shots or nasal spray vaccines, increasing fluid intake, and using warm showers or compresses to relieve symptoms.
brucellosis
Brucellosis is a highly contagious zoonotic disease caused by Brucella bacteria, characterized by fever, sweating, arthritis, and enlarged spleen. It is transmitted from infected animals to humans through contact with tissues/fluids, ingesting raw milk/dairy, or inhalation. Symptoms include intermittent fever over 40°C, joint pain, headaches, and enlarged liver/spleen. Diagnosis involves blood tests showing abnormal white blood cell count and elevated antibodies, with cultures also possible. Treatment consists of antibiotics like doxycycline and rifampin taken for 6 weeks to prevent complications like osteomyelitis, arthritis, or organ abscesses.
Influenza
Influenza is an acute respiratory infection caused by influenza viruses types A, B, and C. Type A is more pathogenic and causes pandemics by mutating into new subtypes. The virus attaches to respiratory cells using hemagglutinin and neuraminidase proteins. Symptoms include fever, cough, and sore throat. Complications can include pneumonia. Antiviral drugs like oseltamivir and zanamivir can reduce symptoms if taken early. Vaccination is recommended for high-risk groups annually.
Rhinovirus
Rhinovirus is the most common cause of the common cold. It is a non-enveloped, positive sense RNA virus that primarily infects the upper respiratory tract. Rhinovirus infections are most frequent and widespread during fall and winter. Symptoms include runny nose, sore throat, coughing, sneezing, and body aches. While the common cold is usually self-limiting, complications can occasionally occur such as sinusitis, ear infections, or pneumonia. There is no vaccine or cure for the common cold. Treatment focuses on relieving symptoms through rest, hydration, analgesics, and in some cases decongestants.
Bordetella pertussis depa
Bordetella pertussis is a small, gram-negative coccobacillus that causes whooping cough. It colonizes the cilia of the respiratory epithelium and produces several toxins that damage cilia and cause symptoms. Pertussis has three stages - catarrhal, paroxysmal, and convalescent. It is diagnosed through culture or PCR of nasopharyngeal secretions. Treatment involves erythromycin, though it may only impact the catarrhal stage. Immunization with whole-cell or acellular pertussis vaccines can prevent the disease.
Smallpox
Smallpox is a highly contagious and often fatal viral disease caused by the variola virus. It was responsible for hundreds of millions of deaths in the 20th century before being eradicated. The disease originated in Africa and spread worldwide. Symptoms include fever, body aches and a distinctive pustular rash. Transmission occurs through respiratory droplets. Vaccination with the smallpox vaccine, developed by Edward Jenner in 1796, was critical to controlling and eventually eradicating the disease globally by 1980. While there is no treatment for smallpox, vaccination provided immunity and mass vaccination programs were important in its eradication.
Rickettsiae
Rickettsial diseases are difficult to diagnose clinically and often go unrecognized, leading to significant morbidity and mortality. They are caused by intracellular bacteria from the Rickettsia genus that are typically spread by arthropod vectors like ticks, fleas and mites. Some of the most common rickettsial diseases found in India include scrub typhus, murine typhus, Indian tick typhus and Q fever. Diagnosis relies on clinical suspicion combined with serology. Treatment involves doxycycline. Prevention focuses on vector control and improving hygiene.

Smallpox disease
Smallpox was intentionally spread among Native American tribes in the 18th century by distributing blankets exposed to smallpox. The disease devastated populations who had no immunity. In the late 20th century, smallpox was developed as an aerosol biological weapon by the Soviet Union. It remains a potential bioterrorism threat. Smallpox is caused by the variola virus and is highly contagious and potentially fatal if left untreated. It was declared eradicated worldwide in 1980 after global vaccination campaigns.
Anthrax
Bacillus anthracis is the etiologic agent that causes the zoonotic disease anthrax. It forms spores that can survive in soil for decades and become activated when they enter the body. There are three main forms depending on route of entry: cutaneous (skin), inhalational (lungs), and gastrointestinal (ingestion). Symptoms vary but can include lesions, fever, vomiting and respiratory distress. Transmission occurs through contact with infected animals/products or inhaling spores. Treatment involves antibiotics like ciprofloxacin or doxycycline for 7-60 days. Prevention involves proper animal product handling, hygiene and immunization of high risk groups.
Plague disease
Plague is a bacterial infection caused by Yersinia pestis that primarily affects the lungs, lymph nodes, and blood vessels. It is a fatal disease that has killed over 200 million people throughout history. There are three main types of plague: bubonic plague causes swollen lymph nodes, pneumonic plague causes coughing and sneezing and can be transmitted between people, and septicemic plague occurs when the bacteria enter the bloodstream directly. Yersinia pestis is usually transmitted to humans via infected fleas or animals. Modern antibiotics can treat plague if diagnosed early enough. Researchers are working to develop vaccines to protect against pneumonic plague.
Pertussis
This document provides an overview of pertussis (whooping cough) including its epidemiology, clinical presentation, diagnosis, treatment and post-exposure prophylaxis.

Pertussis (whooping cough)
- 2. Pertussis is an infectious disease caused by a bacterium called Bordetella Pertussis The bacterium was first isolated in 1906 Small aerobic, gram- negative bacteria Bordetella Pertussis gram stain Bordetella Pertussis under microscope
- 3. The bacteria attaches to cilia of the hosts respiratory cells and produces toxins which paralyze the cilia. This causes the respiratory tract to inflame which causes the excretion of pulmonary secretions difficult.
- 4. Very Contagious disease which is only found in humans. Usually caused by people with Pertussis coughing or sneezing within close contact of other who then breathe in the bacteria.
- 5. 7-10 day incubation period Rarely may be 42 days Illness is divided into 3 stages •Catarrhal Stage •Paroxysmal Cough Stage •Convalescence
