A group of doctors and nurses have contracted a deadly tick-borne virus after treating an infected patient.
 
According to health authorities, a woman in her 60s suspected of suffering from blood poisoning was admitted to an emergency room in Seoul last September. When the woman died, blood analysis showed she was infected with severe fever with thrombocytopenia syndrome (SFTS). 
 
Four doctors and nurses that had contact with the patient became infected in the process of giving the unconscious woman CPR.
 
It is the first case of person-to-person transmission of SFTS to be confirmed in the nation. 
 
SFTS is transmitted by ticks and those infected with the virus suffer from cold-like symptoms, including fever and body aches, after an incubation period of one to two weeks.
