Early recognition and appropriate management are crucial

Zinc Deficiency

Zinc is an essential trace mineral that supports hundreds of physiological functions, from immune response and wound healing to cellular metabolism and DNA synthesis. Zinc deficiency, although often overlooked, can have significant consequences on health and development. Understanding the causes, identifying symptoms, and taking proactive steps to treat and prevent zinc deficiency is critical for

Zidovudine-Induced Anemia

Zidovudine (AZT), a nucleoside reverse transcriptase inhibitor (NRTI), was the first antiretroviral drug approved for the treatment of HIV. While effective in suppressing viral replication, zidovudine is associated with a range of adverse effects, among which anemia is one of the most clinically significant. Zidovudine-induced anemia can limit the drug’s therapeutic potential and compromise treatment

Zaire Ebolavirus Vaccination

Zaire ebolavirus, the most lethal species of the Ebola virus, poses a significant threat to global public health due to its high mortality rate and potential for widespread outbreaks. Vaccination has emerged as a critical tool in mitigating the impact of this filovirus. Effective vaccines have been developed and deployed with measurable success, particularly in

Zaire Ebolavirus Infection

Zaire ebolavirus, a member of the Filoviridae family, is one of the most virulent pathogens responsible for Ebola Virus Disease (EVD), a severe and often fatal hemorrhagic fever. This virus gained notoriety due to multiple deadly outbreaks primarily in Central and West Africa. The Zaire strain (EBOV) is known for its high case fatality rates,
