Influenza A virus, subtype H3N2 virus , kolkatta

 Influenza A virus, subtype H3N2 virus, is a strain of the influenza virus that causes respiratory illness in humans. It is one of the most common strains of the influenza virus that circulates during the flu season.

Kolkata, formerly known as Calcutta, is a city in eastern India. Like many other parts of the world, Kolkata experiences seasonal flu outbreaks, which can be caused by a variety of influenza viruses, including H3N2.

Symptoms of H3N2 influenza virus infection are similar to those of other strains of the flu and can include fever, cough, sore throat, body aches, and fatigue. The flu is primarily spread through respiratory droplets that are released when an infected person talks, coughs, or sneezes.

The best way to prevent H3N2 influenza virus infection is through vaccination. The flu vaccine is typically available annually and is recommended for everyone aged 6 months and older, particularly those who are at high risk for complications from the flu, such as young children, older adults, and individuals with certain underlying medical conditions.

In addition to vaccination, practicing good hygiene habits such as frequent hand washing, covering coughs and sneezes, and avoiding close contact with sick individuals can also help to prevent the spread of the flu. If you suspect that you have the flu, it is important to seek medical attention as soon as possible, particularly if you are at high risk for complications. Treatment options for the flu may include antiviral medications, which can help to reduce the severity and duration of symptoms.

Thyroid hormones are essential for the function of every cell in the body. They help regulate growth and the rate of chemical reactions (metabolism) in the body. Thyroid hormones also help children grow and develop. The thyroid gland is located in the lower part of the neck, below the Adam's apple, wrapped around the trachea (windpipe). It has the shape of a butterfly: two wings (lobes) attached to one another by a middle part. The thyroid uses iodine, a mineral found in some foods and in iodized salt, to make its hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine (T3).

Since the main purpose of thyroid hormone is to "run the body's metabolism," it is understandable that people with this condition will have symptoms associated with a slow metabolism. Causes About three percent of the general population is hypothyroidic. Factors such as iodine deficiency or exposure to Iodine can increase that risk. There are a number of causes for hypothyroidism. Iodine deficiency is the most common cause of hypothyroidism worldwide.
