Study Notes

Cholera

Cholera is a bacterial infection, spread through contaminated water and food.
Infected individuals may experience severe watery diarrhea, vomiting, and dehydration.
Cholera can be fatal if untreated, but prompt rehydration therapy significantly improves survival.

Botulism

Botulism is a serious, life-threatening illness caused by a neurotoxin produced by Clostridium botulinum bacteria.
The bacterium is commonly found in improperly preserved foods, such as canned goods.
Botulism paralyzes muscles, including those involved in breathing.
Symptoms include blurred vision, difficulty swallowing, and muscle weakness.

Foodborne Toxic Infections

Foodborne Toxic Infections are characterized by short incubation periods and persistent immunity.

Viral Diarrheas

Most commonly encountered viral diarrheas include rotavirus infections, parvovirus infections, picornavirus infections, viral hepatitis E, poliomyelitis, tetanus, enteric hepatitis, adenovirus infections and influenza.

Picornavirus Infections

Picornavirus infections are characterized by sudden fever, gastroenteritis, and watery diarrhea.

Protozoal Colitis

Protozoal colitis is caused by various protozoan parasites, including amoebas, balantidia, giardia, and cryptosporidium.

Amoeba

Amoebas exist in various stages of development, including trophozoites and cysts.
Amoebiasis can manifest as intestinal, extraintestinal, or mixed infections.

Viral Hepatitis

Viral hepatitis is an inflammation of the liver caused by various viruses.
Hepatitis viruses can enter the liver through the arterial blood or portal vein.
Hepatitis A and E are transmitted via the fecal-oral route, while Hepatitis B and C can be spread through blood and sexual contact.
Hepatitis A and E viruses make their way to the liver through the portal vein, while hepatitis B and C viruses enter through the arterial blood.

Erysipelas

Erysipelas is a bacterial skin infection caused by Streptococcus pyogenes.
Characterized by redness, swelling, and pain in the affected area.

Rabies

Rabies is a viral disease that affects the central nervous system.
Spread through bites or scratches from infected animals.
Early symptoms include fever, headache, muscle weakness.
In the later stages, rabies leads to delirium, paralysis, and death.

HIV Infection

HIV is a viral infection that attacks the immune system.
Initially, HIV infection may cause flu-like symptoms.
Over time, the virus weakens the immune system, making individuals vulnerable to opportunistic infections.
HIV transmission occurs through blood, semen, vaginal fluids.
Antiretroviral therapy can help to manage HIV infection.

Endogenous Infection

Endogenous infections are caused by opportunistic organisms normally present in the body.
They occur when the body's immune system is weakened.

Infectious Diseases

Shock is a life-threatening condition that can be caused by infectious diseases.

Preventive Measures for Infectious Diseases

Preventive measures for infectious diseases include: vaccination, proper hygiene, and prompt treatment of infections.
