Human coronaviruses (HCoV) cause mild respiratory illness but can lead to severe infections in vulnerable groups. Monitoring these viruses is crucial due to their potential for emergence from animal reservoirs.
Area of Science:
- Virology
- Respiratory Infections
Context:
- Human coronaviruses (HCoV) are single-stranded RNA viruses.
- Four classical/novel HCoVs circulate seasonally, causing mild respiratory infections.
- HCoVs account for 2-7% of respiratory infection hospitalizations.
Purpose:
- To differentiate between common and emerging HCoVs.
- To highlight the increased severity and epidemic potential of SARS-CoV and MERS-CoV.
- To emphasize the need for monitoring HCoVs due to zoonotic potential.
Summary:
- Classical HCoVs cause mild respiratory illness, but affect susceptible populations (children, elderly, immunocompromised) more severely.
- Emerging HCoVs like SARS-CoV and MERS-CoV present greater health risks with higher epidemic potential.
- HCoVs are routinely detected using molecular biology tools alongside other respiratory viruses.
Impact:
- HCoVs represent a significant burden on healthcare systems, especially in hospitalized patients.
- Understanding HCoV circulation and severity is vital for public health surveillance.
- Continuous monitoring is essential to detect and respond to potential HCoV outbreaks from animal sources.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
