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

Stress

Stress can be mainly of two types – physical and psychological. Psychological symptoms include anxiety, depression, aggressiveness, restlessness, panic attack, mood swings, etc. Sometimes due to extreme stress people tend to become increasingly silent, or can react in a manner opposite to their normal behavior.
Physically the symptoms seen affect various parts of our body. For instance when stress affects the nervous system, a person would experience constant headaches or would experience reduced appetite, stomach upset or pain, and in case of the respiratory system one may experience difficulty breathing.
Stress also affects the heart and can lead to a rise or a sudden fall in BP and possibly a heart attacks. It can affects one’s sexual life as wel.

Ignoring stress and living without dealing with it, can leave you with many physical and psychological conditions such as asthma, diabetes, obesity, menstrual disturbance, headache, eating disorder, weight loss and others. It can also lead to the development of heart disease and hypertension.
