There is a new public health crisis threatening the world with the emergence of the novel corona virus-19 or COVID-19 in Wuhan, China and its subsequent global spread. It is believed to have originated in bats and transmitted to humans through yet unknown intermediary animals. The disease is transmitted through inhalation or contact with infected droplets and the usual incubation period is 5 days (range 2-14 days). The symptoms are mild in most people but 15-20 % of patients (usually the elderly and those with comorbidities) may suffer from severe disease. The case fatality rate is estimated to range between 2-3 %. Diagnosis is by specific molecular tests in respiratory samples. Treatment is essentially supportive. The role of antiviral agents is being explored. Prevention is by strict contact and droplet precautions in hospitals for suspected and confirmed cases. Home isolation of patients with mild illnesses is recommended.

Abstract


There is a new public health crisis threatening the world with the emergence of the novel corona virus-19 or COVID-19 in Wuhan, China and its subsequent global spread. It is believed to have originated in bats and transmitted to humans through yet unknown intermediary animals. The disease is transmitted through inhalation or contact with infected droplets and the usual incubation period is 5 days (range 2-14 days). The symptoms are mild in most people but 15-20 % of patients (usually the elderly and those with comorbidities) may suffer from severe disease. The case fatality rate is estimated to range between 2-3 %. Diagnosis is by specific molecular tests in respiratory samples. Treatment is essentially supportive. The role of antiviral agents is being explored. Prevention is by strict contact and droplet precautions in hospitals for suspected and confirmed cases. Home isolation of patients with mild illnesses is recommended.
