Septic 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.
View detailsHepatitis 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.
View detailsCytomegalovirus infection
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.
View detailsCOVID-19
Novel Coronavirus Pneumonia, abbreviated as COVID-19, is an acute respiratory infectious disease caused by a novel coronavirus. This disease was caused by multiple cases of "pneumonia of unknown cause" that occurred in Wuhan, China, in December 2019. On January 10, 2020, Wuhan completed the viral nucleic acid testing for this type of pneumonia, ultimately identifying the pathogen as a novel coronavirus. On February 7, 2020, the National Health Commission decided to temporarily name the disease "新型冠状病毒肺炎" (Novel Coronavirus Pneumonia). On February 11, 2020, the World Health Organization (WHO) named the disease Corona Virus Disease 2019 (COVID-19). On February 22, 2020, the National Health Commission decided to revise the English name of "新型冠状病毒肺炎" to "COVID-19" to align with the WHO naming, while the Chinese name remained unchanged. Currently, the general population is susceptible to this disease. Initial symptoms after infection include fever, fatigue, and dry cough, gradually progressing to severe manifestations such as dyspnea. Some severe cases may develop acute respiratory distress syndrome or septic shock, even becoming life-threatening. Based on clinical manifestations, this disease can be classified into mild, moderate, severe, and critical types: Mild type: Mild clinical symptoms, with no pneumonia manifestations on imaging. Moderate type: Fever, respiratory symptoms, etc., with pneumonia manifestations found on imaging. Severe type: Adults meeting any of the following criteria are considered severe: shortness of breath, respiratory rate ≥30 breaths/min; oxygen saturation ≤93% at rest; arterial partial pressure of oxygen/fraction of inspired oxygen ≤300 mmHg; progressive worsening of clinical symptoms, with lung imaging showing significant lesion progression >50% within 24-48 hours. Children meeting any of the following criteria are considered severe: persistent high fever for more than 3 days; shortness of breath at rest and normal temperature (<2 months old, respiratory rate ≥60 breaths/min; 2-12 months old, respiratory rate ≥50 breaths/min; 1-5 years old, respiratory rate ≥40 breaths/min; >5 years old, respiratory rate ≥30 breaths/min); oxygen saturation ≤93% at rest; presence of accessory breathing signs (nasal flaring, three-recession sign); lethargy, convulsions; refusal to eat or feeding difficulties, signs of dehydration. Critical type: Meeting any of the following criteria is considered critical: respiratory failure requiring mechanical ventilation; shock; co-occurrence of other organ dysfunction requiring ICU monitoring and treatment.
View detailsMycoplasma infection
Mycoplasma are a class of the smallest prokaryotic microorganisms, lacking cell walls, exhibiting diverse morphologies, capable of passing through bacterial filters, and able to survive in inanimate culture media. They are widely found in animals such as cats, dogs, cattle, horses, sheep, chickens, ducks, rabbits, mice, and pigeons, as well as in various plants and soil. Mycoplasma infection refers to various infectious diseases caused by Mycoplasma. Currently, over a hundred species of Mycoplasma are known to be associated with human diseases, with the most common ones including: * Mycoplasma pneumoniae: Primarily causes respiratory tract infections. * Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma urealyticum, Ureaplasma parvum: Primarily cause infections of the genitourinary tract and other sites. Symptoms of this disease mainly involve inflammatory reactions in the respiratory and genitourinary tracts, such as sore throat, cough, fever, urethral swelling, vaginal pain, and painful urination.
