Hepatitis D
Hepatitis D, also known as delta hepatitis, is an infectious disease caused by the hepatitis D virus (HDV) infection, primarily damaging the liver. Since HDV relies on the hepatitis B virus (HBV) for replication, patients with hepatitis D often have concurrent or a history of hepatitis B. The main clinical manifestations of hepatitis D include fatigue, anorexia, dark urine, and right upper quadrant pain.
View detailsToxoplasmosis
Toxoplasmosis is a zoonotic disease caused by infection with *Toxoplasma gondii*. It is distributed worldwide, with approximately 30% of the global population potentially infected with *Toxoplasma gondii*, and about 7.9% in China, mostly asymptomatic. The manifestations of toxoplasmosis are complex and diverse. The vast majority of infected individuals have no obvious symptoms, which is called latent infection; a small number of patients may develop very severe symptoms, which can even be life-threatening. *Toxoplasma gondii* parasitizes nucleated cells in humans and animals, mainly invading the eyes, brain, heart, liver, lymph nodes, and other parts, which can cause toxoplasmic hepatitis, ocular toxoplasmosis, toxoplasmic encephalitis, etc. Infection in pregnant women can affect fetal development and lead to severe malformations.
View detailsSeptic shock
Infectious shock, also known as septic shock, is a life-threatening organ dysfunction caused by a dysregulated host response to infection. The main symptoms include altered mental status, oliguria, and hypotension, accompanied by multiple organ damage.
Hepatitis A
Hepatitis A (HA) is an acute infectious liver disease caused by infection with the hepatitis A virus (HAV). It is common in children and young adults. The main symptoms include fatigue, loss of appetite, diarrhea, and nausea.
View detailsErysipeloid
Erysipeloid is an acute infectious disease caused by the bacterium Erysipelothrix rhusiopathiae (also known as Erysipelothrix insidiosa) entering damaged skin, leading to erysipelas-like skin lesions.

Cytomegalovirus (CMV) is one of the most common pathogens, causing hearing loss and neurodevelopmental delay in children. In immunocompromised individuals, CMV infection can be life-threatening. CMV infection is a congenital or acquired infection caused by cytomegalovirus. CMV infection is very common in the population, but often without obvious symptoms. Neonatal CMV infection can have severe consequences.
View detailsGas gangrene
Gas gangrene is an infectious disease caused by anaerobic Clostridium, leading to deep soft tissue inflammation and necrosis, often secondary to various open wounds such as open fractures with vascular injury, crush injuries with deep muscle damage, prolonged tourniquet application, overly tight plaster casts, or severe trauma near the perianal and perineal regions. This disease primarily manifests as severe pain in the affected area, with possible exudate and foul odor, as well as systemic toxic symptoms. It has an acute onset, rapid progression, and high rates of disability and mortality. Therefore, once it occurs, early diagnosis and timely treatment are crucial to avoid adverse outcomes such as disability or even death.
View detailsAnthrax
Anthrax is a group of acute zoonotic infectious diseases caused by Bacillus anthracis. It is more common in people who have frequent contact with animals and livestock product processing. The disease has an insidious onset and lacks specific early symptoms. Once typical symptoms appear, it will rapidly progress to critical stages such as sepsis and multiple organ failure within 2-3 days, with an extremely high mortality rate.
View detailsHepatitis E
Hepatitis E, fully known as hepatitis E virus infection, is an acute infectious disease caused by infection with the hepatitis E virus (HEV). It primarily affects the liver, with main clinical manifestations including fatigue, loss of appetite, aversion to oily foods, and abnormal liver function. It is mainly transmitted through the fecal-oral route. Most outbreaks of hepatitis E are associated with drinking water contaminated with feces. It is classified as a Class B infectious disease in China.
