MANILA, Philippines?(UPDATE) Three residents and three students of Mapua Institute of Technology campus in Makati City are now confirmed cases of the Influenza A(H1N1) virus, the city government announced on Monday.

Makati public information office chief Joey Salgado said two Filipino residents of San Miguel Village and a child from Barangay Cembo have been hit by the contagious flu virus, based on their communications with the Department of Health.

Meanwhile the three students from the Mapua annex on Gil Puyat, though not Makati residents, reportedly acquired the disease from mingling with affected De La Salle University students.

Salgado said city heath officer Ma. Lourdes Salud will soon announce contingency measures to mitigate the virus' spread in the country's financial district.

He added that the city council was set to hold a special session Monday afternoon to possibly declare a "state of calamity" and release funds for pandemic preparedness plan.

The calamity fund would be used to buy face masks and sanitizers that would be given to public schools and institutions, Salgado said.

Also on Monday, some 1,000 Makati government employees received free flu-vaccine shots as part of a month-long drive to strengthen their immunity.

Around 8,000 city workers-which includes regular, casual and contractual employees-stand to benefit from P2.8-million worth of influenza vaccine meant to prevent the common flu but not the new virus strain.
