MALARIA

Malaria is caused by Plasmodium parasites. The parasites are spread to people through the bites of infected female Anopheles mosquitoes, called "malaria vectors.” There are 5 parasite species that cause malaria in humans, and 2 of these species – P. falciparum and P. vivax – pose the greatest threat.
Malaria is an acute febrile illness. In a non-immune individual, symptoms appear 7 days or more after the infective mosquito bite. The first symptoms – fever, headache, chills and vomiting – may be mild and difficult to recognize as malaria. If not treated within 24 hours, specially for falciparum malaria can progress to severe illness, often leading to death.
In most cases, malaria is transmitted through the bites of female Anopheles mosquitoes. There are more than 400 different species of Anopheles mosquito; around 30 are malaria vectors of major importance. All of the important vector species bite between dusk and dawn

DENGUE



  • Dengue fever is a disease caused by a family of viruses that are transmitted by mosquitoes.
  • Symptoms include severe joint and muscle pain, swollen lymph nodes, headache, fever, exhaustion, and rash. The presence of fever, rash, and headache (the "dengue triad") is characteristic of dengue fever.
  • Dengue is prevalent throughout the tropics and subtropics.
  • Because dengue fever is caused by a virus, there is no specific medicine or antibiotic to treat it. For typical dengue fever, the treatment is directed toward relief of the symptoms (symptomatic treatment).
  • The acute phase of the illness with fever and muscle pain lasts about one to two weeks.
  • Dengue hemorrhagic fever (DHF) is a specific syndrome that tends to affect children under 10 years of age. It causes abdominal pain, haemorrhage (bleeding), and circulatory collapse.
  • The prevention of dengue fever requires control or eradication of the mosquitoes carrying the virus that causes dengue. 
  • There is currently no vaccine to prevent dengue fever.

Matcha Green Tea


Matcha literally means “powdered tea.” When you order traditional green tea, components from the leaves get infused into the hot water, then the leaves are discarded. With matcha, you’re drinking the actual leaves, which have been finely powdered and made into a solution, traditionally by mixing about a teaspoon of matcha powder with a third cup of hot water, which is then whisked with a bamboo brush until it froths.
Matcha preparation involves covering the tea plants with shade cloths before they’re harvested. This triggers the growth of leaves with better flavor and texture, which are hand selected, steamed briefly to stop fermentation, then dried and aged in cold storage, which deepens the flavor. The dried leaves are then stone-ground into a fine powder.

 Matcha is more potent source of nutrients than steeped green tea. In addition to providing small amounts of vitamins and minerals, matcha is rich in antioxidants called polyphenols, which have been tied to protection against heart disease and cancer, as well as better blood sugar regulation, blood pressure reduction, and anti-aging. Another polyphenol in matcha called EGCG has been shown in research to boost metabolism, and slow or halt the growth of cancer cells.

Depression

Depression is feeling sad for weeks or months on end, feelings of hopelessness, feelings of worthlessness and emptiness a lack of energy do anything, and taking little or no pleasure in things that gave you joy in the past. A person who experiences depression cannot often see a future for themselves, and feel like the world is closing in around them. The warning signs and symptoms of depression are usually pretty clear to those around the person suffering — the person doesn’t seem at all like their normal self. The changes in the person’s mood are evident to friends and family.



Symptoms of Depression:
  • Persistent sad, anxious, or empty mood
  • Feelings of hopelessness, pessimism
  • Feelings of guilt, worthlessness, helplessness
  • Loss of interest or pleasure in hobbies and activities that were once enjoyed, including sex
  • Decreased energy, fatigue, being “slowed”
  • Difficulty concentrating, remembering, or making decisions
  • Insomnia, early-morning awakening, or oversleeping
  • Appetite and/or weight loss or overeating and weight gain
  • Thoughts of death or suicide; suicide attempts
  • Restlessness, irritability
  • Persistent physical symptoms that do not respond to treatment, such as headaches, digestive disorders, and chronic pain
