Drought disaster declared for dozens of counties across MN, MT, ND and SD, flue emergency in NY

The U.S. Department of Agriculture (USDA) has declared as drought disaster areas dozens of counties across Minnesota, Montana North and South Dakotas. The designations follow damages and losses caused by the recent drought.

Health emergency declared in NY state amid flu epidemic

New York State has declared a public health emergency, as a severe influenza outbreak tightened its grip across the country.

  • About  20,000 cases of flu have been reported statewide so far this season, a rise of nearly 4 folds on the last season (4,400 confirmed cases in 2012).
  • “We are experiencing the worst flu season since at least 2009, and influenza activity in New York State is widespread, with cases reported in all 57 counties and all five boroughs of New York City,” Governor Cuomo said in a statement. “Therefore, I have directed my Administration, the State Health Department and others to marshal all needed resources to address this public health emergency and remove all barriers to ensure that all New Yorkers – children and adults alike – have access to critically needed flu vaccines Gov. Cuomo said .
  • Public health officials in NY announced last week that flu-related illnesses had reached epidemic levels, killing at least 20 children nationwide.
  • CDC estimates that from the 1976-1977 flu season to the 2006-2007 season, flu-associated deaths each season ranged from a low of about 3,000 people to a high of about 49,000 people.
  • Twenty-four states and New York City are now reporting high ILI activity. Additionally, 16 are reporting moderate levels of ILI activity. States reporting high ILI activity for the week ending January 5, 2013 include Alabama, Colorado, Delaware, Georgia, Illinois, Iowa, Kansas, Louisiana, Michigan, Minnesota, Mississippi, Missouri, New Jersey, New Mexico, North Carolina, North Dakota, Oklahoma, Pennsylvania, Rhode Island, Tennessee, Texas, Utah, Virginia, and West Virginia, CDC said.

More on Swine Flu

UPDATE: Mexican govt says new flu virus probably killed 81

Flu virus particles, or “virions”

The flu is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness, and at times can lead to death. The best way to prevent this illness is by getting a flu vaccination each fall.

Every year in the United States, on average:

  • 5% to 20% of the population gets the flu
  • more than 200,000 people are hospitalized from flu complications, and
  • about 36,000 people die from flu. Some people, such as older people, young children, and people with certain health conditions, are at high risk for serious flu complications.

What you should know:

Influenza A and B are the two types of influenza viruses that cause epidemic human disease. Influenza A viruses are further categorized into subtypes on the basis of two surface antigens: hemagglutinin and neuraminidase. Influenza B viruses are not categorized into subtypes. Since 1977, influenza A (H1N1) viruses, influenza A (H3N2) viruses, and influenza B viruses have been in global circulation. In 2001, influenza A (H1N2) viruses that probably emerged after genetic reassortment between human A (H3N2) and A (H1N1) viruses began circulating widely. Both influenza A and B viruses are further separated into groups on the basis of antigenic characteristics. New influenza virus variants result from frequent antigenic change (i.e., antigenic drift) resulting from point mutations that occur during viral replication. Influenza B viruses undergo antigenic drift less rapidly than influenza A viruses.

CDC – Key Facts about Swine Influenza (Swine Flu)

Under a plate magnification of 37,800X, this colorized transmission electron micrograph (TEM) depicted the A/New Jersey/76 (Hsw1N1) virus, while in the virus’ first developmental passage through a chicken egg. CDC/ Dr. E. Palmer; R.E. Bates (1976).

What is Swine Influenza?

Swine Influenza (swine flu) is a respiratory disease of pigs caused by type A influenza that regularly cause outbreaks of influenza among pigs. Swine flu viruses cause high levels of illness and low death rates among pigs. Swine influenza viruses may circulate in swine throughout the year, but most outbreaks among swine herds occur during the late fall and winter months similar to humans. The classical swine flu virus (an influenza type A H1N1 virus) was first isolated from a pig in 1930.

Can humans catch swine flu? [YES THEY CAN! They already have! Moderator.]

Swine flu viruses do not normally infect humans. However, sporadic human infections with swine flu have occurred. In the past several years, on average CDC has received about one influenza virus isolate from a human that tests positive for swine flu each year. Most commonly, these cases occur in persons with direct exposure to pigs (workers in the swine industry, for example). In addition, there have been rare documented cases of one person spreading swine flu to others. For example, an outbreak of apparent swine flu infection in pigs in Wisconsin in 1988 resulted in multiple human infections, and, although no community outbreak resulted, there was antibody evidence of virus transmission from the patient to health care workers who had close contact with the patient.

This negative-stained transmission electron micrograph (TEM) depicts the ultrastructural details of an influenza virus particle, or “virion”. A member of the taxonomic family Orthomyxoviridae, the influenza virus is a single-stranded RNA organism.  Dated: 1981.  CDC/ Dr. Erskine. L. Palmer; Dr. M. L. Martin

This negative stained transmission electron micrograph (TEM) shows recreated 1918 influenza virions that were collected from supernatants of 1918-infected Madin-Darby Canine Kidney (MDCK) cells cultures 18 hours after infection. CDC/ Dr. Terrence Tumpey (2005)

To separate these virions, the MDCK cells are spun down (centrifugation), and the 1918 virus in the fluid is immediately fixed for negative staining. The solid mass in lower center contains MDCK cell debris that did not spin down during the procedure. See PHIL 8160 for a black and white version of this micrograph.

Dr. Terrence Tumpey, one of the organization’s staff microbiologists and a member of the National Center for Infectious Diseases (NCID), recreated the 1918 influenza virus in order to identify the characteristics that made this organism such a deadly pathogen. Research efforts such as this, enables researchers to develop new vaccines and treatments for future pandemic influenza viruses.

The 1918 Spanish flu epidemic was caused by an influenza A (H1N1) virus, killing more than 500,000 people in the United States, and up to 50 million worldwide. The possible source was a newly emerged virus from a swine or an avian host of a mutated H1N1 virus. Many people died within the first few days after infection, and others died of complications later. Nearly half of those who died were young, healthy adults. Influenza A (H1N1) viruses still circulate today after being introduced again into the human population in the 1970s.
