The two patients are the parents of a 37-year old man who arrived on June 10  from Canada, the Romanian Health Ministry said Sunday.
The two were hospitalized at the “Matei Bals” infectious diseases hospital,  along with their son and his wife. The four are kept under medical supervision  and receive antiviral medicine.
 
The ministry said all AH1N1 virus patients hospitalized in Bucharest so far,  as well as the little girl admitted at the "Victor Babes" infectious diseases  hospital in Timisoara, on June 13, are in a good state.   
 
Nine of the sixteen people infected with the AH1N1 virus have already been  released from hospital.    
 
Romanian health minister Ion Bazac on Friday underscored Romania does not  register cases of widespread infections, adding that, apart from basic hygienic  rules, Romanians need not make any changes in their daily lives.  
  
 Bazac  mentioned masks will be distributed to border police and doctors who come in  contact with people coming in from some of the states most affected by the new  virus, such as the U.S., Canada and Mexico. 
  
 On Thursday, WHO officially  declared the swine flu a pandemic, raising the alert to the highest level of  six.
