Mexico seeks to reassure over deadly swine flu
MEXICO CITY : Mexican authorities sought to reassure citizens Saturday over a deadly new multi-strain swine flu, as the World Health Organization warned that the virus had "pandemic potential."
The outbreak of the new virus transmitted from human to human that has killed up to 60 people and infected hundreds in Mexico and infected eight in the United States is a "serious situation" with a "pandemic potential", the head of the World Health Organization said Saturday.
In Mexico City, where 13 of 20 confirmed deaths occurred, officials said no deaths from swine flu had been registered on Friday, but reassurances came amid the severest public health measures seen here since a 1985 earthquake.
Meanwhile in the United States, where eight non-fatal infections occurred in Texas and California, reports said that 75 students in New York being treated for flu-like symptoms had recently travelled to Mexico, but no swine flu case was confirmed.
"A new virus is responsible" for the cases reported in Mexico and the United States, WHO Director General Margaret Chan said in a telephone press conference Saturday.
How the situation will evolve is "unpredictable," she said, urging other countries to "increase vigilance".
"This virus has clearly a pandemic potential," Chan added.
Mexican Health Minister Jose Angel Cordova confirmed 20 deaths from swine flu late Friday and said authorities were probing another 48 who had died with similar symptoms.
Health officials have been investigating more than 1,000 possible swine flu infections.
Apart from the capital, four other deaths were in central San Luis Potosi, two in Baja California, in northwest Mexico, and one in Oaxaca, in the southeast.
But Cordova added that it was "an epidemic, not a pandemic."
Mexican President Felipe Calderon said that the government would decree necessary emergency or preventative measures.
Authorities on Friday launched a huge campaign to prevent the spread of the virus, urging people to avoid contact in public.
In Mexico City, schools closed for up to a week, according to the health minister, and numerous public venues, including museums and sports stadia were closed to the public.
Mexico City Mayor Marcelo Ebrard said late Friday that 553 sporting and cultural events had been cancelled for at least 10 days to avoid large public gatherings.
The capital did not register any deaths on Friday, Armando Ahued, the local health minister said Saturday.
"The good news is that sick people are reacting adequately to the medication," Ahued said, without giving further details.
Mexico City authorities initially announced a mass vaccination campaign using regular human flu vaccines, but later admitted that the WHO had advised them that it was better to use antiviral medicines, and said they had more than one million doses of suitable drugs.
The CDC website states that there is no vaccine to specifically protect humans from swine flu, only to protect pigs.
The US Centres for Disease Control and Prevention (CDC) said tests show some of the Mexican victims died from the same new strain of swine flu that affected eight people in Texas and California, who later recovered.
The WHO, which was to send a team of experts to Mexico, said Friday that most Mexican cases had occurred in otherwise health young adults.
"Because there are human cases associated with an animal influenza virus, and because of the geographical spread of multiple community outbreaks, plus the somewhat unusual age groups affected, these events are of high concern," the Swiss-based body said in a statement.
Seven other countries on the continent on Friday adopted preventative measures to try to avoid the spread of the virus to their territory.
In Mexico City, medical teams were on stand-by at the international airport, and all passengers had to fill out a health questionnaire.
Human outbreaks of H1N1 swine influenza virus were recorded in the United States in 1976 and 1988, when two deaths were recorded, and in 1986. In 1988 a pregnant woman died after contact with sick pigs, according to the WHO.
In recent years, the global focus for a pandemic has shifted to the H5N1 bird flu virus, which has spread from poultry to humans and killed 257 of the 421 people infected by the virus since 2003.
If a pig is simultaneously infected with a human and an avian influenza virus, it can serve as a "mixing vessel" for the two viruses that could combine to create a new, more virulent strain.
