THE Philippine Red Cross on Wednesday reminded the public to remain vigilant against the Zika virus by preventing carrier mosquitoes from breeding, following a report that an American woman has been tested positive for the virus after a four-week visit to the country. PRC chairman Richard Gordon said it can be done by regularly cleaning surroundings at home and in the communities and discard possible breeding grounds of mosquitoes. “Make prevention everyone’s responsibility. Join or initiate community efforts to clean your surroundings and remove possible breeding grounds of mosquitoes,” Gordon said. He added that the Red Cross remains ready to provide blood in case it would be needed, in the event of a Zika outbreak.
