Answer:
sure mark me brainiest
Explanation:
We have heard the word ‘health’ used quite
frequently. We use it ourselves as well, when
we say things like ‘my grandmother’s health
is not good’. Health’ is therefore a
state of being well enough to function well
physically, mentally and socially.
ACUTE AND CHRONIC DISEASES
The manifestations of disease will be different
depending on a number of factors. Some
diseases last for only very short periods of time,
and these are called acute diseases. We all know
from experience that the common cold lasts
only a few days. Other ailments can last for a
long time, even as much as a lifetime, and are
called chronic diseases. An example is the
infection causing elephantiasis, which is very
common in some parts of India.
As we have seen, it is important to keep public
health and community health factors in mind
when we think about causes of diseases. We
can take that approach a little further. It is
useful to think of the immediate causes of
disease as belonging to two distinct types. One
group of causes is the infectious agents,
mostly microbes or micro-organisms.
Diseases where microbes are the immediate
causes are called infectious diseases. This is
because the microbes can spread in the
community, and the diseases they cause will
spread with them.

Question
define health.explain the types of diseases?
Explanation:
Answer
Types of disease= disease is a particular abnormal condition that negatively affects the structure or function of all or part of an organism, and that is not due to any immediate external injury.[1][2] Diseases are often known to be medical conditions that are associated with specific symptoms and signs.[1][failed verification] A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergies and autoimmune disorders.
In humans, disease is often used more broadly to refer to any condition that causes pain, dysfunction, distress, social problems, or death to the person afflicted, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries, disabilities, disorders, syndromes, infections, isolated symptoms, deviant behaviors, and atypical variations of structure and function, while in other contexts and for other purposes these may be considered distinguishable categories. Diseases can affect people not only physically, but also mentally, as contracting and living with a disease can alter the affected person's perspective on life.
Death due to disease is called death by natural causes. There are four main types of disease: infectious diseases, deficiency diseases, hereditary diseases (including both genetic diseases and non-genetic hereditary diseases), and physiological diseases. Diseases can also be classified in other ways, such as communicable versus non-communicable diseases. The deadliest diseases in humans are coronary artery disease (blood flow obstruction), followed by cerebrovascular disease and lower respiratory infections.[3] In developed countries, the diseases that cause the most sickness overall are neuropsychiatric conditions, such as depression and anxiety.
The study of disease is called pathology, which includes the study of etiology, or cause.
Health=Health is a state of physical, mental and social well-being in which disease and infirmity are absent.
