Typhoid Fever: Pathogenesis (vectors, bacteria), Symptoms, Diagnosis, Treatment, Vaccine

This video series discusses typhoid fever, a bacterial infection caused by Seminella typhi or Paratyphi. It is transmitted through direct or indirect contact with contaminated food or water, and is more common in children and young adults, as well as in overcrowded and unsanitary areas. Symptoms include a stepwise fever, abdominal pain, rose spots, intestinal bleeding, hepatosplenomegaly, diarrhea, constipation, headaches, confusion, delirium, and acute psychosis. Diagnosis is made through suspecting it in the first place and then doing blood and stool cultures. Treatment depends on local resistance patterns and includes fluoroquinolones, zythromycin, tetraxone, and caropenum. Prevention includes fresh water, sanitation, and hygiene, as well as a vaccination. The speaker also encourages viewers to check out their infectious disease playlist and to like, subscribe, and click the notification bell to support the channel.
