CORONARY ARTERY DISEASE (CAD), also known as CORONARY HEART DISEASE (CHD); ISCHEMIC HEART DISEASE (IHD) or simply HEART DISEASE (HD), which involves in reduction of blood flow to the heart veins and muscles, coz of build-up of plaque in the arteries of the heart. It is the most common type of cardiovascular diseases.

CARDIOVASCULAR DISEASES INCLUDE :

• STABLE ANGINA

• UNSTABLE ANGINA

• MYOCARDIAL INFARCTION

• SUDDEN CARDIAC ARREST DEATH

Vaccination of Corona Virus (COVID-19)

VACCINATION :

A COVID-19 Vaccine is a vaccine intended to provide acquired immunity against severe acute respiratory syndrome Corona virus 2 (SARS-CoV-2), the virus that causes the corona virus disease in 2019, (COVID-19). Prior to COVID-19 pandemic, an established body of knowledge existed about the structure and function of coronaviruses causing disease like severe acute respiratory syndrome (SARS) & Middle East respiratory syndrome (MERS). The COVID-19 are widely credited for their role in reducing the spread, severity, and death caused by COVID-19.

Many countries have implemented phased distribution that prioritize those of higher risk of complications such as the elderly, and those of higher risk of exposure and transmission, such as healthcare workers. Single doze interim use is under consideration to extend vaccination to as many people as possible until vaccine availability is improves.

As of 15th September 2021, 5.82 billion dozes of COVID-19 has been administrated World - Wide based on official reports from National Public Health Agencies. AstraZeneca anticipated producing 3 billion doses in 2021, Pfizer Bio-NTECH 1.3 billion doses and Sputnik V, Sinopharm, Sinovac and Janssen 1 billion doses each. Moderna target producing 600 million doses and Convidecia 500 million doses in 2021. By December 2020, more than 10 billion vaccine doses had been preordered by countries, with about half of the doses purchased by high-income countries  comprising 14% of World's population.

.....it's mandatory to inject vaccination ..... 😜 😜

Transmission of Corona virus (COVID-19)

The COVID-19 disease is mainly transmitted via the airborne route when people inhale droplets and small airborne particles (that form a aerosol) that infected people when breath out as they breathe, talk, cough, sneeze or sing. Infected people are more likely to transmit COVID-19 when they are physically close. Infection can occur over longer distance, particularly indoors.

Infectivity begins as early as three days before symptoms appear and people are most infectious just prior to and during the onset of symptoms. It declines after a first week, but infected people remain contagious for up to 20 days. People can spread the disease even if they are asymptomatic.

Infectious particles range in size from aerosols that remain suspended in the air for long periods of time to larger droplets that remain airborne or fall to the ground. Various groups utilize terms such as "airborne" and "droplet" both in technical and general ways leading to confusion around terminology. Additionally, COVID-19 research has defined the traditional understandings of how respiratory viruses are transmitted. The largest droplets of respiratory fluids do not travel far and can be inhaled or land on mucous membranes on the eyes, nose, or mouth to infect. Aerosols are higher in concentration when people are in close proximity, which leads to easier viral transmission when people are physically close, but air borne transmission occur at longer distances, mainly in locations that are poorly ventilated; in those situations particles can remain suspended in the air for minutes to hour.

The number of people generally infected by one infected person varies; as only 10% - 20% people are responsible for the disease's spread. It often spreads in clusters, where infection can be tracked back to an index case or geographical location. Often in these instances, superspreading events occur where people are infected by one person. 

...... this is how transmission occurs ? & this is the end of topic..... 😜 😜 😜

Signs and symptoms of COVID-19

Symptoms of Corona virus (COVID-19) are variable, ranging from mild symptoms to severe illness. Common symptoms include headache, loss of smell and taste, nasal congestion and runny nose, cough, muscle pain, sore throat, fewer, diarrhea and breathing difficulties. People with same infection may have different symptoms and their symptoms change over time. The common clusters of symptoms have been identified : One respiratory system cluster with cough, sputum, shortness of breath and fever, a musculoskeletal symptom cluster with muscle and joint pain; headache and fatigue; and a cluster of digestive systems and abdominal pain, vomiting and diarrhea. In people without prior ear, nose and throat disorders, loss of taste combined with loss of smell is associated with COVID-19.

Most people recover from acute phase of disease. However, some people - over half of cohort of home-isolated with young patients - continue to experience a range of effects such as fatigue after a month of recovery, a condition called long COVID, long-term damage to organs have been observed. Multi-year are underway to further investigate the long-term effects of the disease.

......this is the end of the topic ... 😜 😜 😜

How does the Corona virus (COVID-19) spread/caused ?

COVID-19 transmits when people breathe in air contaminated by droplets and small airborne particles containing the virus. The risk of breathing these in is highest when people are in close proximity, but they can be inhaled over longer distances, particularly indoors. Transmission can also occur if splashed or sprayed with contaminated fluid in the eyes, nose or mouth and rarely via contaminated surfaces. Several testing methods or techniques have been developed to diagnose the disease. The standard diagnostic method is by detection of the virus by nucliec acid by real time reverse transcription polymerase chain reaction (rRT-PCR) transcription-meditated amplification (TMA), or by reverse transcription loop-meditated isothermal amplification (RT-LAMP) from a nesopharyngeal swap.

Preventive measures include physical and social distancing, quarantining, ventilation of indoors spaces, covering cough and sneezes, hand-washing and keeping unwashed hands away from the face. The use of face mask or coverings has been recommended in public settings to minimize the risk of transmission.

While working to underway to develop drugs that inhibit the virus (and several vaccines for it have been approved and distribution in various countries, which have since initiated mass vaccinations campaigns), the primary treatment is symptomatic. Management involves the treatment of symptoms, supportive care, isolation and experimental measures.

.....this is how the corona virus spread & the end of this topic ..... 😜😜

Coronavirus disease 2019 (COVID-19) - Pandemic disease

Coronavirus disease 2019 (COVID-19) is deadly epidemic disease spread by severe acute respiratory syndrome coronavirus 2(SARS-COV 2). It's mainland, engendered and implanted found in Wuhan, China, December 2019. This disease has since caused globally and internationally, leading to ongoing pandemic - it's about to 3rd wave come.

Symptoms of COVID-19 are variable, but mainly include fewer, cough, headache, fatigue, breathing difficulties and loss of smell and taste. Symptoms may begin one to fourteen days after exposure of the virus. At least a third of people who are infected do not develop noticeable symptoms. One who develop noticeable symptoms are enough to be classified as patient, most (81%) develop mild to moderate symptoms while 14% develop severe symptoms (more than 50% lungs involvement on imaging & 5% suffered critical symptoms. Older people are higher risk of developing severe symptoms. Some people are continue to experience the range of affects for the months after recovery and to the organs are observed.
