Alert: Deadly Flu Outbreak In Mexico City


Source : https://dofollownet.com

For the first time in more than 20 years, the federal government has cancelled classes at all levels (from kindergarten up to university). The Minister of Health is investigating 943 cases and estimates that the virus has already killed 16 people so far in April.

"We are faced with a new influenza virus, whose symptoms are: fever over 39 degrees, cough, severe headache, muscle aches and joints, irritation of the eyes and nasal discharge" said Health Minister Jose Angel Cordova, on Thursday night.

While the authorities recognized investigating 16 "suspicious" deaths, the World Health Organization says that there are about 800 suspected cases of swine flu, with 57 deaths in the region of Mexico and similar reported cases in the San Luis Potosi region in the center of the country.

The outbreak could be caused by a new strain of swine influenza A (H1N1), which could have spread from pigs to human, then maybe from human to human.

The U.S. Centers for Disease Control and Prevention also reported that a new variant of H1N1 swine influenza has sickened at least seven patients in California and Texas.

Scientists in Mexico and in the U.S. are trying to determine whether or not the cases in both countries are related and if a pandemic risk exists.

Swine Flu Update: Possible Cases in New York

admin 1 year 16 weeks 1 day 19 hours ago

According to All Headline News, 75 students at St. Stephens Preparatory School (New York) fell ill on Thursday with nausea, fever, dizziness and aches and pains. The symptoms are similar to those experienced by patients in California and in Texas and have similar characteristics to the deadly strain in Mexico.

Testing is under way to rule out the strain of swine flu that has killed dozens in Mexico.

It is highly possible that some of the students have taken a trip to Mexico during the April break.

Mexico Flu Outbreak Follow-Up

admin 1 year 16 weeks 2 days 10 hours ago

Latest results from the US CDC show that in at least 9 cases, the influenza virus strain is the same in Mexico than in southern California and Texas.

But CDC and WHO say that it is not yet time to declare a pandemic, but have prepared "rapid containment measures" in case of emergency. CDC also declared that they will send experts to Mexico to help local scientists investigate the virus.

Cases of swine flu virus transmission from pigs to humans have already been documented in the past, as well as rare cases of direct human-to-human transmission.

To become a pandemic threat, the virus would have to acquire the capacity to rapidly spead from human to human: this could happen only by exchanging RNA sequences with a human influenza strain, which mean that the swine flu virus would need to infect people already infected by a human flu virus.

Statistically, the risk remains very low...but not null.

More information about Influenza Virus and Pandemic

Influenza Virus belongs to the Orthomyxoviridae family and is a Retrovirus, which means that its genetic material is composed of RNA and not of DNA. When infecting an host, it uses a specific enzyme (Reverse Transcriptase) to translate its RNA into DNA and then it inserts this viral DNA into the host's cell DNA. That's how it get "reproduced".

There are 3 types of Influenza viruses:

Influenza A: known to infect birds, pigs, humans, horses, horses and dogs (as well as some other mammals).

Influenza B: known to infect only humans and seals.

Influenza C: known to infect only humans and pigs.

Types B and C are less common than type A, so let's concentrate on Influenza A to which belongs the strain that caused the 1919 deadly pandemic that was coined Spanish Flu and most of the pandemics ever reported.

The Influenza A Virus is a fast mutating virus, i.e., its RNA sequence change regularly and thousands of varieties exist with different genes' combinations. That's what make the conception of vaccines so difficult: each outbreak can be caused by a new strain, generally different enough to make previous vaccines ineffectives. New strains have to be identified in order to create new specific vaccines.

Within type A of Influenza Virus, it exist different subtypes that are identified by 2 proteins: Hemagglutinin (H) and Neuraminidase (N), hence the subtypes names: H1N1, H5N1, H7N3, etc...

Known Human Influenza strains belong to subtypes H1N1, H1N2 or H3N2.

The present Mexico new strain belong to the H1N1 subtype, which is endemic to human and pigs.
