Once COVID-19 start to spread worldwide, some countries obligate the lockdown while another countries announce strict andvsecure preventive measures so which is the best according to your opinion?
Standard recommendations to prevent the spread of COVID-19 include frequent cleaning of hands using alcohol-based hand rub or soap and water; covering the nose and mouth with a flexed elbow or disposable tissue when coughing and sneezing; and avoiding close contact with anyone that has a fever and cough.
Dear dr. Hussein .... Health education and awareness of the dangers of the disease are the best way to prevent all diseases not just viral diseases, while other measures are complementary to the first step such as curfews, staying at home ... etc. ...... thank you for your question

Hi Dr. Lockdown and personal hygiene especially hands washing by soap and water or by using 60% ethanol is a good measure for breakdown COVID 19 spreading chain

Lockdown because it is to enable the more precise and targeted measures that are needed to stop transmission and save lives. “Factors such as population density, urbanization, environmental factors including temperature and humidity, and connectivity to the rest of the world have been shown to drive transmission rates.
Without the lockdowns and other measures in Hubei province, scientists there estimate, the number of Covid-19 cases would have been 67-fold higher
Both strategies are needed depending on the mortality and morbidity rates , furthermore, I opine that the capacity of health system infrastructure to cope with this pandemic is crucial in this regard.
The World Health Organization (WHO) has declared the coronavirus SARS-CoV-2 as an international public health crisis, therefore it is advisable to avoid trips that are not strictly necessary to the areas affected by the coronavirus SARS-CoV-2.
On the one hand, if you have an unavoidable trip to one of these areas, it is advisable to follow the general measures indicated above to reduce the risk of infection and, in addition:
Do not approach live or dead domestic or wild animals and their secretions or droppings in markets or farms.
Do not consume products of animal origin (meat or undercooked or raw food).
In the case of elderly people or those with health problems, who may be at risk of serious illness, they must evaluate the trip together with a healthcare professional at an international vaccination center.
On the other hand, if it is a person who has returned from an affected area, you have to follow the following recommendations:
If the person is well, they can continue with their social, work and educational life; but has to monitor the health status during the 14 days following your arrival. In case of general malaise, cough, fever or feeling of shortness of breath, call 061 and follow the indications. Remember to report not only the symptoms you have, but also the area you have visited.
The two are important:- There is a special class of people. They should follow a full lockdown life, such as patients , children and the elderly, because their immunity is insuffecient to resist the disease.
At the same time, there are important community service departments that must work and continue to work with strict precautions.
World Health Organization says lock-down, shelter-in-place. The key issue is SPREAD. If you do not get in contact with the population, chances are that you will neither contract nor transmit the infection. If people lock-down, the infected people with weak immunity will die while the strong will survive because of sufficient care. Spread is truncated, transmission is non-existent. Normal life returns. However, normal life with restrictions or regulations against people you are not sure of status is very UNWISE. No country has a health system that can handle the spread from the second option. Fatalities will be high. USA and UK tried that and are now paying heavily and dearly. USA now has 22.77% of global COVID-19 deaths and about 31% of total cases. UK is the worst hit in Europe.
Maintain at least 1 metre (3 feet) distance between yourself and anyone who is coughing or sneezing.
Why? When someone coughs or sneezes they spray small liquid droplets from their nose or mouth which may contain virus. If you are too close, you can breathe in the droplets, including the COVID-19 virus if the person coughing has the disease.
Lock-down is an easy manner to prevent the spread of COVID 19, but has many bad effects. The regulated life that using strict preventive measures is good in control COVID 19 and important to the economy... like what happening in China nowadays.
Both can be effective. However, avoid touching eyes, nose and mouth.
Why? Hands touch many surfaces and can pick up viruses. Once contaminated, hands can transfer the virus to your eyes, nose or mouth. From there, the virus can enter your body and can make you sick.
Make sure you, and the people around you, follow good respiratory hygiene. This means covering your mouth and nose with your bent elbow or tissue when you cough or sneeze. Then dispose of the used tissue immediately. Why? Droplets spread virus. By following good respiratory hygiene you protect the people around you from viruses such as cold, flu and COVID-19.
Stay home if you feel unwell. If you have a fever, cough and difficulty breathing, seek medical attention and call in advance. Follow the directions of your local health authority.
Why? National and local authorities will have the most up to date information on the situation in your area. Calling in advance will allow your health care provider to quickly direct you to the right health facility. This will also protect you and help prevent spread of viruses and other infections.

Hong Kong took the route that the World Health Organization recommends and embarked on a rigorous programme of testing everyone with symptoms. Those who tested positive were quarantined in hospital. All their contacts over recent days were traced and instructed to self-isolate. Strict controls were brought in at the borders. Anyone arriving from mainland China or a country with Covid-19 cases was required to go into quarantine for 14 days. Holiday camps and new but unoccupied housing estates were turned into quarantine facilities. Schools were closed and people were encouraged to work from home if they were able to. Hong Kong has not had that sort of lockdown. Although people were not required to stay at home, they chose to change their behaviour.
By quickly implementing public health measures, Hong Kong has demonstrated that Covid-19 transmission can be effectively contained without resorting to the highly disruptive complete lockdown.
What if the Coronaviruse is able to survive near boiling point of water?
SARS-CoV-2 direct diagnosis is based on RNA detection by RT-qPCR. The most common protocol for virus deactivation is the one-hour-60 degrees Celsius heating technique. In combination with the use of Triton X-100,it has been recommended by CDC.
Experiment have been conducted to prove that when infected cells are heated to about 92 degrees Celsius for 15 minutes, viruses are denatured entirely. However,this is not a feasible solution because,at such temperatures, the viral RNA becomes fragmented, causing the number of false negatives to rise.
According to WHO, COVID 19 transmitted through air and sustain for long time period and may infect to the another person. So, the minimum 1 meter distance from the infected person does not implies properly to stop COVID 19 spread. Many scientists concluded that the only way to stop the spread by physical distancing from one another. Temperature and humidity is another factor for minimizes the the spread out.
Eventually even with lifting of social restrictions we need to exercise good hygiene and minimize contact until a vaccine protects us or when a majority of the population has had it and is immunized. Let's just say R0 = 3 under normal conditions. To control the transmissions need to get R0 below 1, which means reducing 3-ft contact by more than 2/3's. But we can do that by not shaking hands with strangers, washing hands more, etc.
Smart lock downs with restricted business timings.
This means social distancing, masking, and use of hand hygiene, thermal screening of people, and not allowing children and older people in gatheraings.
This was successful in South Korea. Pakistan is also following it.
Lock down would be most secure, but may not be a long-term solution and can cause its own social deprivation problems. I believe that precautions such as wearing a mask when near people, keeping distance as much as possible, and washing your hands with a good disinfectant often can reduce transmission probability by about 90% and that should allow going out and conducting normal activities to some extent.
Both actually. Only lockdown can't be the solution as it's not possible for an unlimited time for any country. Sweden's soft strategy based on strict preventive measures without lockdown. China showed the hardest lockdown so far. South Korea showed the quickest response so far. Decision-making is an important issue in the prevention of pandemic crisis as it's beyond individual.
