article imageSwine flu returns to Mexico

In January Mexico registered a resurgence in flu of all types, including the H1N1 strain (also known as swine flu), with more cases in one month than in all of 2011, according to Health Secretary Salomon Chertorivski Woldenberg.
CBS News reported Mexico's early 2012 influenza spike that spread northward from Chile and the Andes along with the Health Secretary's reassurance that the sudden increase and larger number of cases falls within expectations for a typical flu season in the country, where 5,000 to 11,000 reported cases of all flu strains during the flu season is not unusual.
"Last year, H1N1 barely circulated in the country or in the world," Chertorivski explained, to put the recent sudden increase in perspective.
Chertorivski told reporters that of 1,623 cases flu documented by health officials in January, 90 percent were H1N1; and that 32 people had died from flu, all but three from the H1N1 strain.
In the spring of 2009, Mexico became the epicenter of a worldwide H1N1 pandemic, and because the virus at first appeared to have a super-high mortality rate, Mexican authorities then closed schools, libraries, museums and restaurants in efforts to prevent its spread.
Since then, the low appearance of H1N1 and other flu strains caused pharmacies to understock antiviral drugs, but Chertorivski said sufficient doses are available now throughout the country, CBS News reported.
According to the Centers for Disease Prevention and Control (CDC) and the online drug, disease and procedure reference Medscape, the 2009 H1N1 influenza (swine flu) was caused by one of several swine influenza A viruses.
The CDC now refers to the virus as 2009 H1N1, and the disease is spread person to person through coughing, sneezing and touching infected surfaces and fluids, according to PubMed Health
Although the World Health Organization in August 2010 declared the H1N1 pandemic was over, the virus is still circulating, and the vaccine for H1N1 (that is more likely to cause vomiting and diarrhea than other flu strains) is included in the 2011-2012 seasonal flu vaccine, according to Flu.gov.
