Folk music is an integral part of our culture. The life of the rural people is reflected in folk music. Our agriculture, food, seasons, and rituals are all reflected in these songs. Village people express their weal and woe and feelings through different form of folk music like Palligiti, Bhatiwali, Jari, Sari, Lalon Giti, Palagan, etc. But people's taste for music has changed over time. As people migrate to cities and villages transform, our traditional folk songs are slowly fading. Folk music or Palligiti is now sung with western instruments. At the same time, modern music is now fusing melodies from folk and traditional songs. In general band and pop music is becoming more and more popular, particularly among the young generation. Yet folk music has a great importance in our everyday life today. As this song is deeply rooted in our culture, people still derive pleasure listening to folk music. Besides, folk music is still used in mainstream films and music albums.

Dengue Fever

Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. This virus spreads among people through the bite of an infected Aedes species mosquito. Symptoms typically begin three to fourteen days after infection. These may include a high fever, severe headache, vomiting, muscle and joint pains and characteristic skin rash. In small portion of cases, the disease develops into a severe hemorrhagic dengue fever. This results in bleeding and low levels of blood platelets. There are no specific antibiotics to treat dengue fever. Antiviral medications are also not indicated for dengue fever. Treatment of acute dengue is supportive care. Paracetamol is recommended for fever reduction and pain relief. Taking sufficient rest is also important. For more severe cases, blood transfusion may be required. Aedes mosquitoes typically lay eggs near standing water in containers that hold water, like buckets, bowls, animal dishes, flower pots and vases. So the best method of preventing dengue includes destroying mosquito habitat and limiting exposure to bites. This may be done by throwing standing water and wearing thick clothes that cover much of the body. Most importantly, everyone's awareness against dengue can halt the outbreak of this disease.

How COVID-19 Spreads

Coronavirus disease (COVID-19) is an infectious disease caused by the SARS COV-2 virus. This disease spreads through close contact with an infected person. When an infected person coughs, sneezes, or talks, the virus of this disease spreads. The virus comes out through the nose and mouth in droplets and if a healthy person inhales the droplets, he or she will be affected too. The droplets can also sit on the surface of any object. When someone touches that surface with bare hands, the virus gets transmitted to his hands. After that, if the person touches his nose, mouth or eyes, the virus gets into his respiratory system. After getting infected, a person might expose no symptom for several days or weeks. This means the infected person may not show symptoms of sickness at the beginning. This period is very dangerous because the infected person can unknowingly affect other healthy people. To avoid infection, social distancing, wearing masks while staying outside, washing hands with soap and water frequently, or cleaning hands with hand sanitizers are essential. Besides, we can make our immune system stronger by following the health rules, taking nutritious food, drinking a lot of liquid and doing light exercise. Even after getting fully vaccinated, we must follow these measures to prevent COVID-19.
