However, there has been at least one documented case of human-to-human transmission of swine flu. In March and April 2009, over 1000 cases of suspected swine flu in humans were detected in Mexico and the Southwestern United States of California, Texas, New Mexico? The Mexican 2009 swine flu outbreak, of a new strain H1N1 influenza virus was first detected by in March 2009. As of April 26, 2009, Mexico City schools, universities, and all public events remained closed or suspended while other schools in the U.S. closed due to confirmed cases in students. On April 27, 2009, Mexican government officials announced a nationwide shut down of schools.
This never-before-seen strain of swine flu has turned killer in Mexico and is causing milder illness in the United States and elsewhere. While authorities say it's not time to panic, they are taking steps to stem the spread and also urging people to pay close attention to the latest health warnings. They urge people to take common-sense precautions including covering your coughs and sneezes, with a tissue that you throw away or by sneezing into your elbow rather than your hand. Washing ones hands frequently and if soap and water aren't available, with alcohol-based hand sanitizer or gels is also advised. As a precaution, people are advised to avoid close contact with someone who's sick and avoid crowded gatherings in places where swine flu is known to be spreading.
The good news however is that swine flu is sensitive to and treatable with the flu drugs oseltamivir (Tamiflu) and zanamivir (Relenza). Face mask is also advised to effectively cover a person's mouth and nose so that if a person is around someone who is infected, there is a decreased likelihood of transmission. It is said that the available scientific evidence does not support the general wearing of face-masks by those who are not ill, whilst going about their normal activities. Currently there is no vaccine for swine flu but vaccines are available to be given to pigs to prevent swine influenza. There is no vaccine to protect humans from swine flu. The seasonal influenza vaccine will likely help provide partial protection against swine H3N2, but not swine H1N1 viruses. Symptoms of swine flu are similar to those of common influenza and includes fever, cough, sore throat, lethargy, lack of appetite, while runny nose, nausea, body aches, headache, chills and fatigue. A few other patients have also reported diarrhea and vomiting.
People should avoid touching their mouth, nose or eyes with their hands unless they've washed their hands. If people do cough, they should either cough into a tissue and throw it in the garbage immediately, cough into their elbow, or, if they cough in their hand, they should wash their hands immediately. Generally, swine flu viruses spread through uncovered coughs and sneezes or by touching your mouth or nose with unwashed hands? Swine Flu is spread between humans through coughing or sneezing of infected people and touching something with the virus on it and then touching their own nose or mouth. Flu viruses can live on surfaces for several hours, like a doorknob just touched by someone who sneezed into his hand. The swine flu in humans is most contagious during the first five days of the illness although some people, most commonly children, can remain contagious for up to ten days. Swine flu cannot be spread by pork products, since the virus is not transmitted through food.
This particular Mexican swine flu has unusually been aggressive on healthy young adults, much like the deadly Spanish Flu of 1918, unlike most other influenza strains which devastate young children and elderly adults as well as others with weaker immune systems. Icheoku hopes medical sciences will once again rise up to the challenge and stop this swine flu inn order to save humanity from possible extinction assuming it takes a turn for the worst!

Mexico's … By E. EDUARDO CASTILLO and PAUL HAVEN, Associated Press Writers E. Eduardo Castillo And Paul Haven, Associated Press Writers – 50 mins ago
MEXICO CITY – The swine flu epidemic entered a dangerous new phase Monday as the death toll climbed in Mexico and the number of suspected cases there and in the United States nearly doubled. The World Health Organization raised its alert level but stopped short of declaring a global emergency.
The United States advised Americans against most travel to Mexico and ordered stepped up border checks in neighboring states. The European Union health commissioner advised Europeans to avoid nonessential travel both to Mexico and parts of the United States.
The virus poses a potentially grave new threat to the U.S. economy, which was showing tentative early signs of a recovery. A widespread outbreak could batter tourism, food and transportation industries, deepening the recession in the U.S. and possibly worldwide.
The suspected number of deaths rose to 152 in Mexico, the epicenter of the outbreak with nearly 2,000 people believed to be infected.
The number of U.S. cases rose to 50, the result of further testing at a New York City school, although none was fatal. Other U.S. cases have been reported in Ohio, Kansas, Texas and California. Worldwide there were 79 confirmed cases, including six in Canada, one in Spain and two in Scotland.
The World Health Organization reported a slightly lower figure, 73. The WHO said it was still awaiting official reports from the U.K. about the Scottish cases, and it was reporting different numbers in the U.S. (40) and Mexico (26) from what those governments confirmed.
While the total cases were still measured in hundreds, not thousands, Mexican Health Secretary Jose Angel Cordova said the epidemic was entering an extremely dangerous phase, with the number of people infected mushrooming even as authorities desperately ramped up defenses.
"We are in the most critical moment of the epidemic. The number of cases will keep rising, so we have to reinforce preventative measures," Cordova said at a news conference.
The WHO raised the alert level to Phase 4, meaning there is sustained human-to-human transmission of the virus causing outbreaks in at least one country.
Its alert system was revised after bird flu in Asia began to spread in 2004, and Monday was the first time it was raised above Phase 3.
"At this time, containment is not a feasible option," as the virus has already spread to several other countries, said WHO Assistant Director-General Keiji Fukuda.
Putting an alert at Phases 4 or 5 signals that the virus is becoming increasingly adept at spreading among humans. That move could lead governments to set trade, travel and other restrictions aimed at limiting its spread.
Phase 6 is for a full-blown pandemic, characterized by outbreaks in at least two regions of the world.
It could take 4-6 months before the first batch of vaccines are available to fight the virus, WHO officials said.
Russia, Hong Kong and Taiwan said they would quarantine visitors showing symptoms of the virus amid global fears of a pandemic, an epidemic spread over a large area, either a region or worldwide.
President Barack Obama said the outbreak was reason for concern, but not yet "a cause for alarm."
Dr. Richard Besser, acting director of the Centers for Disease Control and Prevention, said that so far the virus in the United States seems less severe than in Mexico. Only one person has been hospitalized in the U.S.
"I wouldn't be overly reassured by that," Besser told reporters at CDC headquarters in Atlanta, raising the possibility of more severe cases in the United States.
"We are taking it seriously and acting aggressively," Besser said. "Until the outbreak has progressed, you really don't know what it's going to do."
U.S. customs officials began checking people entering U.S. territory. Millions of doses of flu-fighting medications from a federal stockpile were on their way to states, with priority given to the five already affected and to border states. Federal agencies were conferring with state and international governments.
"We want to make sure that we have equipment where it needs to be, people where they need to be and, most important, information shared at all levels," said Janet Napolitano, head of the Homeland Security Department.
"We are proceeding as if we are preparatory to a full pandemic," Napolitano said.
She said travel warnings for trips to Mexico would remain in place as long as swine flu is detected.
Mexico canceled school at all levels nationwide until May 6, and the Mexico City government said it was considering a complete shutdown, including all public transportation, if the death toll keeps rising. Labor Secretary Javier Lozano Alarcon said employers should isolate anyone showing up for work with fever, cough, sore throat or other signs of the flu.
Even some of Mexico's most treasured national holidays were affected by the swine flu alert.
Authorities announced Monday the cancellation of the annual Cinco de Mayo parade, in which people in period costumes celebrate Mexican troops' defeat of a French army on May 5, 1862. The national labor umbrella group announced the cancellation of Mexico City's traditional May 1 parade and the National Institute of Anthropology and History said all of its 116 museums nationwide would be closed until further notice.
Amid the warnings, the Mexican government grappled with increasing criticism of its response. At least two weeks after the first swine flu case, the government has yet to say where and how the outbreak began or give details on the victims.
The health department lacked the staff to visit the homes of all those suspected to have died from the disease, Cordova said.
Cordova said 1,995 people have been hospitalized with serious cases of pneumonia since the first case of swine flu was reported April 13. The government does not yet know how many were swine flu.
He said tests show a 4-year-old boy contracted the virus before April 2 in Veracruz state, where a community has been protesting pollution from a large pig farm.
The farm is run by Granjas Carroll de Mexico, a joint venture half owned by Virginia-based Smithfield Foods, Inc. Spokeswoman Keira Ullrich said the company has found no clinical signs or symptoms of the presence of swine flu in its herd or its employees working anywhere in Mexico.
Mexico's Agriculture Department said Monday that its inspectors found no sign of swine flu among pigs around the farm in Veracruz, and that no infected pigs have been found yet anywhere in Mexico.
As if the country did not have enough to deal with, Cordova's comments were briefly interrupted by a 5.6-magnitude earthquake in southern Mexico that rattled already jittery nerves and sent mask-wearing office workers into the streets of the capital.
Aside from the confirmed cases, 13 are suspected in New Zealand, and one is suspected in both France and Israel.
European Union Health Commissioner Androulla Vassiliou advised Europeans to avoid nonessential travel to Mexico and parts of the United States, although Besser said that including the U.S. in the advisory seemed unwarranted at this time.
State Department spokesman Robert A. Wood said Vassiliou's remarks were his "personal opinion," not an official EU position, and therefore the department had no comment.
"We don't want people to panic at this point," Wood said.
The U.S. stepped up checks of people entering the country by air, land and sea, and the State Department warned U.S. citizens to avoid nonessential travel to Mexico. It said those who live in Mexico should avoid hospitals or clinics there unless they have a medical emergency.
The best way to keep the disease from spreading, Besser said, is by taking everyday precautions such as frequent handwashing, covering up coughs and sneezes, and staying away from work or school if not feeling well. He said authorities are not recommending that people wear masks at work because evidence that it is effective "is not that strong."
Besser said about 11 million doses of flu-fighting drugs from a federal stockpile have been sent to states in case they are needed. That's roughly one quarter of the doses in the stockpile, he said.
There is no vaccine available to prevent the specific strain now being seen, he said, but some antiflu drugs do work once someone is sick.
If a new vaccine eventually is ordered, the CDC already has taken a key preliminary step — creating what's called seed stock of the virus that manufacturers would use.
Many of the cases outside Mexico have been relatively mild. Symptoms include a fever of more than 100, coughing, joint aches, severe headache and, in some cases, vomiting and diarrhea.
European and U.S. markets bounced back from early losses as pharmaceutical stocks were lifted by expectations that health authorities will increase stockpiles of anti-viral drugs. Stocks of airlines, hotels and other travel-related companies posted sharper losses.
WHO spokesman Peter Cordingley singled out air travel as an easy way the virus could spread, noting that the WHO estimates that up to 500,000 people are on planes at any time.
Governments in Asia — with potent memories of previous flu outbreaks — were especially cautious. Singapore, Thailand, Japan, Indonesia and the Philippines dusted off thermal scanners used in the 2003 SARS crisis and were checking for signs of fever among passengers from North America. South Korea, India and Indonesia also announced screening.
In Malaysia, health workers in face masks took the temperatures of passengers as they arrived on a flight from Los Angeles.
China said anyone experiencing flu-like symptoms within two weeks of arrival had to report to authorities.
China, Russia and Ukraine were among countries banning imports of pork and pork products from Mexico and three U.S. states that have reported swine flu cases, while other countries, such as Indonesia, banned all pork imports.
The CDC says people cannot get the flu by eating pork or pork products.
Germany's leading vacation tour operators were skipping stops in Mexico City as a precaution. The Hannover-based TUI said trips through May 4 to Mexico City were being suspended, including those operated by TUI itself and through companies 1-2 Fly, Airtours, Berge & Meer, Grebeco and L'tur.
Japan's largest tour agency, JTB Corp., suspended tours to Mexico through June 30. Russian travel agencies said about a third of those planning to travel to Mexico in early May had already canceled.
WHO to stop using term 'swine flu' to protect pigs

Slideshow:Swine Flu Play Video Video:Swine Flu vaccine KVUE-TV Austin Play Video Video:Swine flu cases increase in Europe Reuters AP – A traditional Hungarian 'mangalitsa' pig sticks its snout out of the hurdle at a private pig farm in … By FRANK JORDANS, Associated Press Writer Frank Jordans, Associated Press Writer – Thu Apr 30, 7:02 pm ET
GENEVA – The World Health Organization announced Thursday it will would stop using the term "swine flu" to avoid confusion over the danger posed by pigs. The policy shift came a day after Egypt began slaughtering thousands of pigs in a misguided effort to prevent swine flu.
WHO spokesman Dick Thompson said the agriculture industry and the U.N. food agency had expressed concerns that the term "swine flu" was misleading consumers and needlessly causing countries to ban pork products and order the slaughter of pigs.
"Rather than calling this swine flu ... we're going to stick with the technical scientific name H1N1 influenza A," Thompson said.
The swine flu virus originated in pigs, and has genes from human, bird and pig viruses. Scientists don't know exactly how it jumped to humans. In the current outbreak, WHO says the virus is being spread from human to human, not from contact with infected pigs.
Egypt began slaughtering its roughly 300,000 pigs Wednesday even though experts said swine flu is not linked to pigs and not spread by eating pork. Angry farmers protested the government decree.
In Paris, the World Organization for Animal Health said Thursday "there is no evidence of infection in pigs, nor of humans acquiring infection directly from pigs."
Killing pigs "will not help to guard against public or animal health risks" presented by the virus and "is inappropriate," the group said in a statement.
China, Russia, Ukraine and other nations have banned pork exports from Mexico and parts of the United States, blaming swine flu fears.
Most in the Muslim world consider pigs unclean animals and do not eat pork because of religious restrictions. The farmers in Egypt raise the pigs for consumption by the country's Christian minority.
WHO also reported the number of confirmed swine flu cases rose to 257 worldwide Thursday, with cases in Mexico rising to 97 from 26, with seven deaths. The WHO confirmed tally from the United States now stands at 109, with one death.
Other confirmed cases include 34 in Canada, 13 in Spain, eight in Britain, three each in Germany and New Zealand, two in Israel and one each in Austria, Switzerland and the Netherlands.
WHO raised the pandemic flu alert to phase 5 on Wednesday, one step away from the highest level indicating a global outbreak. WHO flu chief Keiji Fukuda said Thursday there were no indications in the past day that would prompt the U.N. body to raise the alert further.
To move from pandemic alert level 5 to level 6 means that WHO believes there is evidence of big outbreaks in at least two world regions and a pandemic is under way.
Fukuda said the jump in confirmed cases from Mexico was probably the result of scientists working their way through a backlog of untested samples from suspected cases.
"They are going through several thousands of laboratory specimens right now," he said.
WHO has started distributing its stockpile of 2 million treatments of the antiviral drug Tamiflu to regional offices, which will decide where to send them next.
Many of those drugs will go to developing countries that don't have stockpiles of their own and some will be sent to Mexico, Fukuda said, without providing figures.
