Can swine flu be transmitted to humans?

Can humans be infected with swine influenza viruses? Yes. Swine flu viruses do not normally infect humans, however, sporadic human infections with influenza viruses that normally infect swine have occurred.

Is H1N1 worse than H3N2?

Conclusions: Influenza A H3N2 infection was more severe than A H1N1 or B in terms of fever, leukopenia, and C-reactive protein. Myalgia and other symptoms such as fever, headache, general malaise and sore throat were equally frequent in influenza A H3N2, A H1N1, and B infections.

Why is the flu a public health issue?

However, influenza represents a major public health issue due to the associated hospitalizations and excessively high number of deaths. Aging (>65 years old), comorbidities, pregnancy and compromised immune system are considered risk factors associated with higher rates of hospital admissions and mortality.

What is H3N2 called?

Influenza A H3N2 variant viruses (also known as “H3N2v” viruses) with the matrix (M) gene from the 2009 H1N1 pandemic virus were first detected in people in July 2011. The viruses were first identified in U.S. pigs in 2010.

How did H1N1 spread from pigs to humans?

The virus likely spreads from pig to pig through contact with infected mucous secretions. (When pigs are really sick, their mucous carries high levels of virus). Strains of swine flu virus also can be directly transmissible to humans. Most human infections occurred following direct contact with infected pigs.

Is there a vaccine for H1N1?

The 2009 influenza A (H1N1) monovalent vaccine was released in mid October. The immunization series consisted of 2 doses for children younger than 10 years, consisting of an initial dose and a booster to be administered several weeks later. Adults and children 10 years and older received a single dose.

Is H3N2 the swine flu?

H3N2v is a non-human influenza virus that normally circulates in pigs and that has infected humans. Viruses that normally circulate in pigs are “swine influenza viruses.” When these viruses infect humans, they are termed “variant” viruses.

Can you get H3N2 twice?

A double-barreled flu season occurs when two flu outbreaks overlap one another, a pattern which is very unusual, according to flu experts. Last year, for example, we saw A/H1N1 infections peak early, followed by another wave of A/H3N2 infections.

What is CDC purpose?

Mission. CDC works 24/7 to protect America from health, safety and security threats, both foreign and in the U.S. Whether diseases start at home or abroad, are chronic or acute, curable or preventable, human error or deliberate attack, CDC fights disease and supports communities and citizens to do the same.

How does the CDC monitor the flu?

Treatment for influenza virus infection is guided by laboratory surveillance for antiviral resistance. Influenza surveillance and targeted research studies are used to monitor the impact of influenza on different segments of the population (e.g., people in certain age groups, people with underlying medical conditions).

What is h3 influenza?

Influenza A virus subtype H3N2 (A/H3N2) is a subtype of viruses that causes influenza (flu). H3N2 viruses can infect birds and mammals. In birds, humans, and pigs, the virus has mutated into many strains. In years in which H3N2 is the predominant strain, there are more hospitalizations.

Do meat pigs need vaccines?

A vaccination program is encouraged in order to protect your pigs’ health. The basic vaccinations for feeder pigs are atrophic rhinitis (bordetella), actinoba- cillus pleuropneumoniae (APP), mycoplasmal pneumonia, and erysipelas.
