H 1 n 1 flu virus

I was severely sick. I have had SOB, occasional dry cough for a few years, he contributes to my asthma. Sleep study was normal.

Googling everything. Possibly pulmonary fibrosis or lung cancer. Anyone with some opinions would be greatly appreciated. I am not sure if the virus or the vaccine is the cause of my health issues but right after both my immune system started overreacting. I developed a few inflammatory diseases. It has been 10 years since the last time I had a fever. I am not sure if I have an amazing immune system or my immune system has collapsed.

Pandemic Preparedness Influenza pandemics are uncommon; only three have occurred since the pandemic. Get an annual flu vaccine to protect you against seasonal influenza. A seasonal flu vaccine will NOT protect you against a novel influenza A virus; but it is good practice and lays the groundwork for development and administration of a pandemic flu vaccine.

Learn, teach to others, and practice everyday preventative actions that can help slow the spread of germs. Stay home when you are sick. Avoid close contact with people who are sick. Social distancing avoiding close contact with others is one of the most important personal nonpharmaceutical interventions that people can take to help avoid getting sick. Cover your coughs and sneezes. Wash your hands often. Create an emergency supplies kit that includes personal needs , such as soap, hand sanitizer with at least 60 percent alcohol, and tissues.

Close-knit communities are often more resilient in a disaster, like a pandemic. Keep up to date on health news, and turn to reliable sources of information like your local government. Monitor local news coverage for public health advisories and information about temporary school closures and large event cancellations. Beware of misinformation and rumors, especially on social media.

We cannot wait.!!! Hello, In light of recent events, specifically with the measles outbreak in New York, the importance that this article highlights continues to provide guidance for future pandemic episodes. Hello, The relevancy this article provides holds true to this day.

Influenza D viruses primarily affect cattle and are not known to infect or cause illness in people. Influenza A viruses are divided into subtypes based on two proteins on the surface of the virus: hemagglutinin H and neuraminidase N. There are 18 different hemagglutinin subtypes and 11 different neuraminidase subtypes H1 through H18 and N1 through N11, respectively. Reassortment can occur when two influenza viruses infect a host at the same time and swap genetic information.

This graphic shows the two types of influenza viruses A and B that cause most human illness and that are responsible for flu seasons each year. Both influenza A and B viruses can be further classified into clades and sub-clades which are sometimes called groups and sub-groups. Note that this graphic is an example, and currently circulating influenza clades and subclades may differ from those presented here. Figure 1 — This is a picture of a phylogenetic tree.

Each sequence from a specific influenza virus has its own branch on the tree. The degree of genetic difference between viruses is represented by the length of the horizontal lines branches in the phylogenetic tree. The further apart viruses are on the horizontal axis of a phylogenetic tree, the more genetically different the viruses are to one another.

An influenza clade or group is a further subdivision of influenza viruses beyond subtypes or lineages based on the similarity of their HA gene sequences. See the Genome Sequencing and Genetic Characterization page for more information. Clades and subclades are shown on phylogenetic trees as groups of viruses that usually have similar genetic changes i. Dividing viruses into clades and subclades allows flu experts to track the proportion of viruses from different clades in circulation.

Note that clades and sub-clades that are genetically different from others are not necessarily antigenically different.

These proteins act as antigens. Antigens are molecular structures on the surface of viruses that are recognized by the immune system and can trigger an immune response such as antibody production. Therefore, for antigenically different viruses, immunity developed against one of the viruses will not necessarily protect against the other virus as well.
