Ebola virus disease (EVD) is a severe, often fatal illness, with a case fatality rate of up to 90%. It is one of the world’s most virulent diseases.The infection is transmitted by direct contact with the blood, body fluids and tissues of infected animals or people. Severely ill patients require intensive supportive care. During an outbreak, those at higher risk of infection are health workers, family members and others in close contact with sick people and deceased patients. Ebola outbreaks can devastate families and communities, but the infection can be controlled through the use of recommended protective measures in clinics and hospitals, at community gatherings, or at home.
Viral hepatitis kills approximately half a million people every year in the 11 countries of WHO’s South-East Asia Region. An estimated 100 million people are currently infected with hepatitis B virus and another 30 million with hepatitis C virus. These chronic infections have the potential to progress to cirrhosis and cancer of liver.
The World Health Organization (WHO) has been officially notified by the China National Health and Family Planning Commission about human infection (and deaths) with an influenza virus subtype A(H7N9) that has not been previously reported in humans. There is no indication of human-to-human transmission associated with these patients. WHO is working closely with it's Collaborating Centres for influenza to discuss and strengthen diagnostics and case management. At present, the reservoir, source of infection and mode of transmission remain unknown.
Coronaviruses are a large family of viruses that includes viruses that may cause a range of illnesses in humans, from the common cold to SARS. Viruses of this family also cause a number of animal diseases.
This particular strain of coronavirus has not been previously identified in humans. There is very limited information on transmission, severity and clinical impact with only a small number of cases reported thus far.
