Virus wiki

Highly pathogenic avian influenza A(H5N1) primarily affects poultry and wild birds; sporadic human infections raise pandemic preparedness attention.

Chikungunya virus causes fever and often debilitating joint pain; outbreaks follow Aedes-borne transmission and can stress outpatient services during peaks.

Cholera is acute diarrheal disease caused by toxigenic Vibrio cholerae; outbreaks track unsafe water, sanitation, and hygiene failures.

COVID-19 is respiratory disease caused by SARS-CoV-2. Global surveillance tracks cases, severity, and regional pressure to highlight emerging waves and healthcare stress.

Dengue is the most common mosquito-borne viral disease globally; repeated infections increase risk of severe dengue in some individuals.

Ebola virus disease is severe filovirus illness managed through isolation, supportive care, and community-engaged response.

Hantaviruses cause hemorrhagic fever with renal syndrome and hantavirus pulmonary syndrome depending on region; exposure often follows aerosolized rodent excreta.

Seasonal influenza viruses cause recurrent epidemics; zoonotic influenza subtypes remain under global watch for pandemic potential.

Lassa fever is an arenavirus hemorrhagic fever endemic in parts of West Africa, associated with rodent reservoirs and nosocomial spread risk.

Marburg virus causes severe viral hemorrhagic fever; outbreaks require rapid contact tracing, safe burials, and strict infection prevention and control.

Mpox (monkeypox) is orthopoxvirus disease with zoonotic reservoirs and human-to-human transmission; outbreak dynamics vary by network contacts and vaccination coverage.

Nipah virus is a zoonotic paramyxovirus with high case-fatality risk; outbreaks are often linked to bats, pigs, or contaminated food products in South and Southeast Asia.

Zika virus is a mosquito-borne flavivirus associated with outbreaks in tropical and subtropical regions; surveillance focuses on vectors, travel-related cases, and congenital risk signals.
