Are you not bothered about Covid-19?
A global crisis has shocked the world. It is causing a tragic number of deaths, making people afraid to leave home, and leading to economic hardship not seen in many generations. Its effects are rippling across the world.
And nothing about the human response to COVID-19 will either. The evolutionary arms race between humans and viruses has existed for millennia. Our bodies, packed with nutrients and the machinery of cellular reproduction, are irresistible targets for exploitation by smaller and faster-evolving organisms
Whereas viruses benefit from rapid replication rate and mutation potential, allowing them to quickly adapt to exploit their hosts, humans are not left defenseless. Natural selection has endowed us with a complex physiological immune system
That targets viruses at a cellular level and a behavioral immune system
that modulates human behavior to reduce the risk of contagion. Moreover, our ability to communicate and develop vast repositories of information, paired with intelligence and innate curiosity, allowed us to engineer extraordinary tools such as modern medicine. And, we have developed cultural systems of coordination that can allow us to erect walls for limiting the spread of disease
It is possible that SARS-CoV-2 has been particularly successful because it is highly infectious before symptoms appear. Suppressing the sickness-related behavior of hosts is one way that viruses can increase their fitness. Hosts that are infected but do not feel sick are more likely to go about their usual activities, which allows them to come in contact with others whom they might infect. If they do not display symptoms of infection, the human behavioral immune system fails to activate in others (see Insight 3: Activating Disgust Can Help Combat Disease Spread), silently spreading to new hosts.

the 1918 influenza virus
And Borna disease virus
although causality is impossible to establish with this evidence. One study administered the influenza vaccine as a proxy for infection and found a significant change in social behavior—for the 48 h after receiving the vaccine (during the time of peak transmissibility), people interacted with others more (from 51 to 101 people) and in larger groups (from 2.4 to 5.5) than in the 48 h before receiving it
This study suggests exposure to viral antigens can have effects on host social behavior and is consistent with what would be expected if viruses alter host behavior to enhance viral transmission. By understanding how SARS-CoV-2 is evolving and having behavioral and psychological effects on us that enhance its transmission, we will be better able to shape its evolutionary trajectory so it becomes less harmful and less lethal.
The COVID-19 pandemic has been a part of our daily lives since March 2020, but with about 115,000 new cases a day in the United States and the U.S. death toll at more than 464,000, it remains as important as ever to stay vigilant and know how to protect yourself from coronavirus.
Covid-19, Save The Human Race for Know how it spreads
Scientists are still learning about COVID-19, the disease caused by the coronavirus, but according to the CDC, this highly contagious virus appears to be most commonly spread during close (within 6 feet) person-to-person contact through respiratory droplets.
Practicing good hygiene is an important habit that helps prevent the spread of COVID-19. Make these CDC recommendations part of your routine:
The means of transmission can be through respiratory droplets produced when a person coughs or sneezes, or by direct physical contact with an infected person, such as shaking hands
Practice social distancing -
The CDC recommends maintaining a distance of approximately 6 feet from others in public places.
Practicing good hygiene is an important habit that helps prevent the spread of COVID-19. Make these CDC recommendations part of your routine:
Wash your hands often with soap and water for at least 20 seconds, especially after you have been in a public place, or after blowing your nose, coughing, or sneezing.
- Before eating or preparing food
- Before touching your face
- After using the restroom.
- After leaving a public place
- After blowing your nose, coughing, or sneezing.
- After handling your mask.
- After changing a diaper.
- After caring for someone who’s sick.
- After touching animals or pets.
If soap and water are not readily available, use a hand sanitizer that contains at least 60% alcohol. Cover all surfaces of your hands with the sanitizer and rub them together until they feel dry.
Avoid touching your eyes, nose, and mouth with unwashed hands
In addition to hand-washing, disinfect frequently touched surfaces daily. This includes tables, doorknobs, light switches, countertops, handles, desks, phones, keyboards, toilets, faucets, and sinks.

“Soap molecules disrupt the fatty layer or coat surrounding the virus, ” says Dr. Goldberg.“ Once the viral coat is broken down, the virus is no longer able to function.”
“Face masks are designed to provide a barrier between your airway and the outside world,” says Dr. Ole Vielemeyer, medical director of Weill Cornell ID Associates and Travel Medicine in the Division of Infectious Diseases at NewYork-Presbyterian/Weill Cornell Medical Center and Weill Cornell Medicine. “By wearing a mask that covers your mouth and nose, you will reduce the risk of serving as the source of disease spread by trapping your own droplets in the mask, and also reduce the risk of getting sick via droplets that contain the coronavirus.
Travel increases your chance of getting and spreading COVID-19.
states the CDC. “Staying home is the best way to protect yourself and others from COVID-19.”
For people at risk for the complications of COVID-19, such as those with underlying medical conditions or those who are older, it’s prudent to avoid travel,
Travel between provinces will be restricted considering the increasing caseload of COVID-19 in the country
Most common symptoms:
fever
dry cough
tiredness
Less common symptoms:
aches and pains
sore throat
diarrhea
conjunctivitis
headache
loss of taste or smell
a rash on the skin, or discoloration of fingers or toes
Serious symptoms:
difficulty breathing or shortness of breath
chest pain or pressure
loss of speech or movement
Seek immediate medical attention if you have serious symptoms. Always call before visiting your doctor or health facility
People with mild symptoms who are otherwise healthy should manage their symptoms at home.
On average it takes 5–6 days from when someone is infected with the virus for symptoms to show, however it can take up to 14 days.
Herbal Medicine is Powerful enough to save the Life of a Covid-19 infected person.
have been used to treat respiratory infections like the Influenza trusted Source and pneumonia.
Supermarkets and smaller retailers have run out of ginger, coriander, turmeric, yellow vine, and lime, and Ayurveda practitioners warn there may not be enough supplies to produce the wide range of indigenous medicinal products that many Sri Lankans trust over Western medicine.
practitioners recommend the consumption of herbal drinks using coriander and venivel to boost the immune system, a practice that has been strongly advocated amid the COVID-19 pandemic.
Particular tradition uses hundreds of medicinal plant extracts to strengthen the immune system. These include commonly used herbs such as turmeric and yellow vine, to lesser-known plants.
A host of other plants are used in Ayurveda to treat common illnesses. These include adhatoda or Malabar nut (Justicia adhatoda), Indian lilac or neem (Azadirachta indica), white or Indian sandalwood (Santalum album), red sandalwood (Pterocarpus santalinus), black pepper (Piper nigrum), bin kohomba (Munronia pinnata), katuwel batu or wild eggplant (Solanum virginianum), suvanda kapuru (Gaultheria leschenaultii), heen araththa or snap ginger (Alpinia calcarata), nelli or Indian gooseberry (Phyllanthus emblica), and rasakinda or heart-leaved moonseed (Tinospora cordifolia).
Sri Lanka has at least four established traditional treatment systems: Ayurveda, Unani, Siddha, and Deshiya Chikitsa, or indigenous treatment — all popular methods of treating people.
Besides the use of medicinal plant resources in Ayurveda, herbs are extensively used in Sri Lankan homes to build up immunity, fight contagious diseases, and in cooking. Herbal drugs play a key role on native preventive care, with many Sri Lankans relying on traditional remedies over Western medicine. Fear of the side effects associated with the latter is one of the factors that drive people to prefer native treatments as the safer option.
